Defying gravity By Peter Hildebrandt
Some people might wonder what it is that makes a person want to hang from ropes tens or hundreds of feet above the ground. Have they always wanted the feeling of having nothing under their feet? Or do they just decide to try it once and then get hooked?

continued from page 8 night. The exhibit featured the square root function curve brought to life with hanging pendulums. If pendulums are hung along this square root function curve, each pendulum will start in unison, go out of phase and go into a sine wave phase and then back into unison. “That was a real challenge,” says Evans. “We called Riley and luckily he was in town at the time to give us his opinions on some things. Riley pointed out a number of things we could do to get this to work. We eventually got the series of pendulums to work according to the formula and it worked great once we had that input from him. Another Gravity Design member, Dave Freitag, will say at times – referring to Riley’s guidance, ‘we have to call in the wolf on this’. Bringing history to life at a busy terminal Another big show was at the San Francisco International Airport. Joanna Haigood, artistic director for the Zaccho Dance Theatre wanted to represent the history of the Black experience in America from the slave trade all the way through the pop culture of James

fly “through” a piece of scenery on their way to the ground. The entire show was on a series of cycles. Each cycle took about thirty minutes to complete. The show was continuous for two hours. From the ground the dancers did their dance to the music and video presentation before climbing back up a ladder to a tightrope that had been set up by Gravity Design for them to walk back up to the boat trusses. They then climbed back down into the houses once again. All of this took place while the public walked around below, getting to their flights or heading to baggage claim areas. The show ran for two different weekends at the airport. “Riley’s major contribution to all these projects is that he sits down with
Brown. Part of her vision for Departure and Arrival was to have performers enter from the “slave ships,” fashioned from the huge boat trusses at the airport’s relatively new International Terminal. This venue features large stands of trusses, curved and coming out to a point over a 130 foot span. “In this visually striking performance, performers rise up in this ‘hull’ of a ship and come down through space to steel-framed houses, dancing through them and then down into the ground. Following this they dance their indoctrination into America.” This was a particularly challenging design because the performers needed to move in three- dimensions through the space, flying vertically and horizontally, changing directions in mid air. Even more complicated, the choreography called for the performers to

the artists and figures out how to realize their visions,” says Evans. “Often the artists are not grounded in the laws of physics; Riley has to interpret what they see, what they want to see and then tell them what’s possible. “The other thing Riley brings to these situations and Gravity Design is that he’s a tremendous problem solver. He can access a situation, see the dynamic forces at work in the structures that he’s trying to build and he can figure out how to stabilize and work with the dynamic flow within the realm of safety and feasibility of the architecture and art structure that we’re adding to it.” Doing what you do best Evans thinks of himself as the right hand man in the partnership giving feedback and working to solve problems. And then there is Evans’s other title. He is affectionately known as the “crash test dummy.” After they build a system the first thing they do is put dead weight on it. The next step after that is to put a live load on the system. Nine times out of ten Evans is the live load testing out the system. “I always have secondary and tertiary lines backing me up just in case something goes wrong on that first time. Ninety-nine point nine times out of one hundred nothing goes wrong. “The most important thing in rigging safely and effectively is to allow outside perspective to come in. You have to work in pairs, in tandem. It’s very easy when you work alone to be overconfident in your abilities to some degree; that’s when mistakes happen – and why it’s important to be able to bounce ideas off another person that you can believe in and trust.” Riley agrees. “Spencer and I have been working together so long we can usually finish each-other’s sentences, but every once in a while we don’t agree, and when we do we always stop and find out what’s on each-others minds. That goes for all the riggers at Gravity, anyone can ask a question, or raise a concern at anytime. Ultimately that makes for a safer working environment, and encourages individuals to take responsibility for the safety of what they are doing. Spencer and I are both careful to maintain an open book policy on information about any given job, because it builds trust, which is a commodity you can’t buy at any price.” Another show Gravity Design worked with the Zaccho Dance Theater on, took place at Jacob Pillow in the Berkshires of Massachusetts.

continued from page 10 five to six weeks and featuring 40-50 different artists. This Zaccho Dance Theater site-specific piece took place in a barn on the property at the festival. The barn had at one time been an actual station on the Underground Railroad. A story on the slave trade, the path to freedom and the Underground Railroad proved a natural fit. This was pretty much straight dance theater until the very end when Riley and Evans set up a big line on which they were able to drag the main performer up from one side to the other, from 10 feet off the ground, to the other side which was 100 feet off the ground and a big slide that they dragged the woman up along the line – flying up to freedom. On the big 160’ slide they built a Tyrolean, two wire ropes stacked on top of each other and each tensioned independently. The pulley system which dragged the performer up had to have the two segments of rope balancing perfectly. Evans, doing his crash test dummy thing, was 60 feet from each point, jumping up and down trying to get as much dynamic load into that cable as he could. With his dynometer in place Evans was pulling 600 pounds

on the slide at its peak. At that point they were well within the working load of the material. “Digital load cells and real time dynamic data acquisition are a big part of Gravity Design’s safety program,” says Riley. “Accurate calculations can be very difficult or even impossible on a dynamic or ‘moving’ live load, so it’s imperative to know what’s really going on inside a system.” Sharp enough to overcome the razor’s edge Through their relationship with Joanna Haigood and Zaccho Dance Theater they’ve cultivated another one with a group in Brooklyn, New York,
called Sens Productions, under the direction of Noémie Lafrance. “Lafrance is a very ambitious artist,” says Evans. “She wants to do aerial dance work on Frank Gehry’s architecture. The main factor that Gravity Design must deal with in working with Gehry’s buildings is that they are curve-linear, stainless steel, priceless - and razor sharp.” When they went to Bard College to set up a show, La France didn’t know what she wanted and Gravity Design didn’t know what to expect with the exception of looking at a few pictures online. When Evans got into the harness on the Gehry building site at Bard College and everything was in place, he noticed that the parapet was standard but the stainless steel paneling covering the sweep of the roof was as sharp as a razor blade. It was torch cut eighth-inch, stainless steel. Evans set himself up with his harness on a virtually horizontal spot and put the rope – a 10.5 mil nylon superstatic rescue line – over the edge. He mimicked what it would be like on the parapet side in an effort to see how much they could interact with these side panels. When he shook his head continued on page 14

continued from page 12 twice the rope cut instantly, like a hot knife through butter. “The answer to the question of how much we could interact with these steel panels was: not at all,” says Evans. They built some truss structures that would allow them to not interact with the sharp panels at all. The way their typical systems work is they use wire rope to anchor from the structure of the architecture to a place where they can safely place their piece of poly rope or dancer line over the edge. Then on their dancer lines the performers are able to use either ascending or descending climbing hardware to change their position on the line as they perform. The Petzl Grigri is the tool of choice for them. On this Gehry project Riley and Evans were able to introduce different types of apparatus that the performers could work with. It was the standard, rope over the edge of the building and swing on. Because of the nature of that architecture and what this choreographer wanted they were able to expand how the dancers interacted with the building. The dancers weren’t always on a totally vertical plane on their wall. Some
of their walls were like rolling hills. One of the systems used was a 30 foot fall-arrest seat belt, yo-yo type of equipment activated by force of gravity. “We set up one of those with a little rigging on it, placing it on a little two to one and the performer could go 45 or 50 feet comfortably if he was just walking against his current falling weight but as soon as he put the force of gravity into it and he mimicked himself falling then the thing would lock up and he would be fixed there in that position. Then he could work against the fixed line and do different movement vocabularies because he was on a rigid line now. Safety lines for the tough times Gravity Design gets a lot of their wire rope from Cable Moore in Oakland. And much of their gear comes from the folks at Rescue Direct, and Sterling Rope. Their supplier in San Francisco is The Carpenter Group, a wire rope rigging and supply company which places a major emphasis on safety. Besides inspection and testing of customer rigging and hardware, they offer on-going safety training seminars to show their customers how to recognize unsafe rigging practices.

Evans still works locally with a few theater companies providing technical services. Gravity Design has a fairly small niche they are involved with. Word of mouth drives their business presently. Much of the funding this year has come from an energy efficiency lighting retrofit for a major retailer. Evans goes around and lays out more efficient lighting for a department store as he has in Detroit and Seattle. Riley has been taking a bit of a break from Gravity Design while hosting the National Geographic Channel Program, World’s Toughest Fixes, so Evans has gone solo much of the past two and a half years. “I think it was a good move for him. But the challenge for Gravity Design is that with the Recession, much of the spending for arts funding dried up. But things are working out and funding recently seems to be picking up. We’re flexible people and it’s not in our natures to stay on the ground for very long.” WRN

The mystery of suspension bridge cable corrosion and the Forth Road Bridge’s solution By Peter Hildebrandt
“A riddle wrapped in a mystery, inside an enigma” sounds a lot like the how, why and where of suspension bridge cable corrosion today. Though the cables can look great on the outside, looks can be more than deceiving: they can be downright dangerous.

But that was just being undertaken, not all bridges stand in the midst of National Geographic’s World’s Tough- the same climate conditions as those est Fixes host Sean Riley visited the Forth Road Bridge located in South Queensferry, Scotland. (The show aired in May 2010.) Riley’s job was to help tie Ethernet wire to cables while hanging some 300 feet above the bridge’s road deck. The wires went from cable monitors down to a computer below that would help engineers know when a wire in AECOM engineers inspecting the main cable. one of the two main cables of the bridge had broken. at New York Harbor, and time has As a master rigger, Riley enjoys the brought with it rather puzzling corrofeel of the “air under my feet, swinging sion at other bridges.

The Forth Road Bridge is a suspension bridge, and was the longest in Europe and the fourth-longest in the world when it opened in 1964. (The other three are in the United States.)

continued from page 16 mary load-carrying capacity lies in the main cables. This bridge followed the same principles as the American engineer John Roebling’s Brooklyn Bridge did when it opened in 1883, using spun cables. In the case of the Forth Road Bridge, some 11,618 individual high-tensile wires run parallel and were compacted together. They were then wrapped around a circumference with a nine-

creating a microclimate which brings abundant moisture to the area where the bridge is situated. The overall climate on the east side of Scotland is surprisingly cold and dry, especially in comparison to the western side of the country state, even some 50 miles away which can have double the rainfall of the eastern side due simply to the mountains running north-south down the west side of the country, causing a rain shadow. Taking a Good Look Despite how seemingly solid and protected the cables appeared, during the start of the late 1970s, 80s and 90s in the U.S., bridge owners began to investigate their bridges by looking inside the main cables. There were some problems with corrosion. A way was developed to let them look inside. “They discovered quite significant corrosion in a number of cases,” says Colford. “In the late 1990s the National Academy of Engineering in the U.S. put together a program for developing a guide for the inspection of main ca-

gauge wire and red lead paste applied before the wire was wrapped in and then finally painted. Each of the two main cables on the bridge supports some 14,000 tons of load. “A rather standard type of protection was applied to the bridge in 1964,” explains Colford. “But the problem was that the technology in 1964 was based on what the Roeblings did on their Brooklyn Bridge in 1883. Wires were galvanized and then smeared with lead-based paint. Everyone had always thought this would work. And here at the Forth Road Bridge, on the outside it looked like that would be good enough and that everything was alright inside the cable,” says Colford. “But what we found was that being good on the outside clearly doesn’t mean being good on the inside, and that painting doesn’t work.” The reason painting doesn’t work is because even though the cables look rigid, they are actually rather flexible and move about an awful lot. Paint is not up to bridging the cracks where cable bands join. Water will get in. Once it is in, that is it. Then Neoprene wrap on its own also doesn’t work.

vanized finish or something else or a combination of factors is uncertain. “When we were spinning the cables the wind caused a real issue during the construction,” says Colford. “During the process of receiving advice from Roebling’s company, those individuals involved from the firm noted how windy it was compared to other major American bridges such as the George Washington or the Golden Gate Bridge.” As at the Golden Gate Bridge, a similar sea mist in Scotland called the Sea Haar moves in from the North Sea

bles in suspension bridges and an evaluation of their reduced strength. We were involved from Forth Road Bridge with colleagues from Golden Gate and the various bridge owners from New York, in particular Bill Monroe from the New York State Bridge Authority which looks after bridges like Bear Mountain, Hudson River bridges and those in upstate New York.” This guideline which came out in 2004 was assembled by Roebling Company and the American consulting engineers by Ron Milborough.

continued from page 18 decided to inspect their own cable despite the fact that there was no sign of exterior deterioration or water coming out from the cable. The cable had been well-maintained. But the guide recommended inspection after a period of 30 years and so FETA decided to inspect the cables. “FETA was the first to use the guidelines outside of the U.S., and a number of people in Europe and the U.K. wondered if we really needed to do it,” says Colford. “At this bridge, it is 80 meters be-

tween the hanger points where the load is hanging onto the main cables. Frankly, we thought we’d open one panel at low level and find we had nothing, wrap it back up and go away. Using a brass chisel we wedged the wire slightly open and could see right inside it. To our surprise, we found corrosion in the panels. We found that approximately 8-10% of the cable strength had been lost over time and we had considerable corrosion, despite it looking fine on the outside,” says Colford. “We decided if we didn’t do something

about it, this would mean at some point in the future we’d have to implement loading restrictions on the bridge and we couldn’t afford to do that.” A total of ten panels were inspected during 2004 and 2005 – approximately 4% of the total cable length. This small sampling of the cable was used to discover the strength lost at that time, then extrapolated into the future to make a determination of what the strength loss of the bridge would be in five or ten years if nothing were done. This is the point at which engineering becomes as much an art as a science, according to Colford. This includes the making of judgments based on available basal knowledge. To inspect the cables, work starts with a softer metal chisel such as brass to gently pry the wires apart. They are in a circular pattern and there are over 11,000 wires. Plastic wedges which will not damage the cables are then used, at twelve o’clock, two, four and so on around the cable. Observers can look down the wedges right into the middle of the cable. Corrosion can be seen with the naked eye – the best inspection tool available, according to Colford. Until the wires of the cables were uncovered and pried apart for inspection it was anyone’s guess as to where the greatest damage from the moisture would be. Perhaps intuitively, reasoning suggests it should be near the base as the cable starts its rise. However, when Philadelphia’s Walt Whitman Bridge was inspected for corrosive damage, the most extensive corrosion due to moisture was found at the penultimate sections of the cables - just before they reached the top of the suspensions bridge towers, according to Colford. On the Forth Road Bridge corrosion was most extensive midway between the towers – at the lowest point of the cable. “We looked at various options we had at that point,” says Colford. “We knew that some of the owners in the States had opened up all the cables and oiled them and that some with similar problems had put neoprene wrap over them on top of the painted surface just to keep water out. But we were aware there’d been limited success with this and weren’t convinced it was the right option. Oiling the cables involves opening up the whole cable and that is a significant cost. A New Technique Using…Air FETA had to do something or they were facing the prospect of the cable deteriorating. They knew that in Ja-
pan a new technique for suspension bridges was being studied using de-humidification. The process involved wrapping the cables with a neoprene wrap and passing air with a relative humidity of less than 40% up through the voids between the wires to try and drive out the moisture being caused by the water and oxygen present in Inspecting corrosion in the wedged open main cable. those spaces.

sion products within the cable.” The installation of the dehumidification system of the cable was finished in October 2009 and there is now dry air being pumped continually into the main cables. It is likely that monitoring of the strength-loss versus time graph for the bridge cables will continue, according to Colford. The hope is that the rate of deterioration stabilizes. One of the issues is that FETA knows that there will be cracks within these wires and the cable. What happens to these cracks from now until the end of the cable’s life, perhaps some 80 to 100 years time, will persist as an area for study. The main question remains, will these cracks develop into breakages and reduce the strength of the continued on next page

continued from previous page cable or not? The dehumidification technique employed here has not been universally accepted in the United States. “It has been accepted in Europe and Japan,” says Colford. “It’s starting to be accepted in China but it hasn’t been universally accepted there yet either. Peter Sluszka of Ammann and Whitney Consulting Engineers, New York has helped us as well as Wayne Langer. Langer bangs the drum for dehumidification. There hasn’t been a great response as yet; but we think it is the only way to prevent further deterioration and should be installed on all new suspension bridges – though I don’t think it’s happening in the States yet.” In 2012 FETA will be going back in to re-inspect the cable by opening up 10 panels at low and high levels. “We will have to repeat that exercise either every five or ten years, depending on what we find each time,” adds Colford. “So for the remainder of the life of the cable this will have to be done. Without that, it is difficult to evaluate strength. And what we will also do is gain more confidence. Maybe through time we can cut the interval to every 20 or perhaps 15 years. But it will still have to be done to make sure that the
dehumidification, if it does succeed, is continuing to succeed.” One thing FETA has also done is to fit acoustic monitoring onto the cables. These consist of a series of listening devices which pick up wire breaks by eavesdropping for them. A wire break can actually be detected in this manner. This is a web-based system so they can easily pick up any problems by going onto the website involved with this monitoring system. This has been going on since 2006. But it does have its limitations. It doesn’t tell the history: in other words, whether a wire break has been the first one or the eleven thousandth. It does not predict the future either, only telling the observer what is happening currently. For now, wrapping the cable in neoprene and then applying dehumidification is the only way a cable can be made to remain dry or be become dry. “Certainly if I were building a suspension bridge from the start I would insist that it come with a built-in dehumidification system,” says Colford. “This is very cheap to do at the beginning. It is a lot harder to do if you are attempting to retrofit it. Our dehumidification systems cost us 11 million pounds, or close to 15 million dollars – a lot of money with no guarantee of
success. “As a result of this work, I think our experience has shown others that new bridges need to be built with dehumidification systems. One suspension bridge in Norway, the Haldangar Bridge, I think is being fitted with such a system. Any new ones will be built with that in mind. Cable stay bridges are becoming more the norm today as replacement on the of suspension bridge cables involves shutting down the whole bridge, which is expensive and time-consuming.” The decision to construct a new cable stay bridge beside the Forth Road Bridge is currently going through the Scottish Parliament. Construction is due to start on the structure in 2011. It is out to bid currently. Hopes are it may be completed by 2016. “I am confident that we can keep the cables on our bridge going for the rest of their service life,” says Colford. “It is just a matter of monitoring them at this point and onward. Though I am confident the dehumidification will work; I can’t give an unconditional guarantee either. We are continuing to monitor the ‘patient’ as things go along. We’ve done what we can. Now it’s just a question of waiting to see if it works.” WRN

Hessville Cable & Sling Co. thrives in the industrial thick of things By Peter Hildebrandt
Hessville Cable & Sling Company, Gary, Indiana turned 50 in 2010. These days, in times of mergers, buyouts, shutdowns, bankruptcies, layoffs and overall stress on firms throughout the region, country and world, making it to a half century of service is a big milestone. The company continues to play a vital role in the development of what was already a highlyindustrialized area of the state and the country. Gary Indiana has been a steel production center since the start of the 20th Century.
F
ounder who truly knew the ropes Located just south and west of downtown Gary, the company is currently owned by two brothers, George and Ken Randall. Their father, Boyd Randall, started the business back in 1960, working part-time out of a less than one-car garage. He had to roll the reels of wire rope out of the garage first, just to be able to have space to do his work there. During the day he worked as an ironworker in the steel mills in Gary with crews constructing such iconic edifices as the Prudential Building in Chicago. He dedicated his “free” time in the evenings to cable splicing. Boyd Randall’s extensive skills had been honed in the 1940s and 1950s while he worked on the Wattsbar Dam in Tennessee, the Kentucky Dam and on many other Tennessee Valley Authority (TVA) projects. Following Randall’s settlement in northwest Indiana in 1954, stories of his reputation, his knowledge and proficiency got around in a hurry. The area’s steel and construction industries boomed in this era and superior cable was a key element in each main production venture. A family business was born when Ken and George Randall came on with Hessville Cable in 1960. Two other sons, Tom & Max Randall worked hard with the company, adding to its tremendous growth as a new company. Contracts almost doubled each year. Eventually the Randalls reached the decision to give the company time and space it needed to grow. They rented a small building in Hessville. Two years later they used a $500 loan from the Inland Credit Bureau to purchase cable they could use to mass produce slings. 24
Boyd’s sons had grown up right along with the company. But the family’s strength and mettle would be sorely tested before the decade was over. In 1966 Boyd Randall was killed at his work in a local steel mill. Randall was only 54 years old, far too young to be taken away
from a family and community that looked up to him and had been impressed by his thriving local business. Instead of giving up, the loss strengthened the commitment to this venture their father had started. George and Ken Randall decided to continue to build the wire rope business. Years later Ken related that though these were difficult times and a tough decision to make, the choice to carry on was also clear-cut. Carrying on without their father at the helm was not anything either of the Randall brothers had ever imagined. But Ken said, “We felt he truly wanted us to finish what he’d only just started.” “When his sons started out they were in their early 20s. Now they are in their 70s and still active in the company,” says Don Hennessy, general manager. “Ken and George also have two brothers who work for Hessville Cable. Those brothers, Tom Randall and Max Randall, were also both extremely instrumental in the growth of Hessville Cable
Wire Rope News & Sling Technology April 2011
& Sling over the years.” Hennessy has been with the company for over eight years, though he has been in the wire rope industry for 36 years, employed by two rigging shops before coming on with Hessville Cable. Hennessy hails from nearby Michigan, another state which is no stranger to industrial growth and leadership. Hessville Cable remains a family-owned business where collaboration and solidarity make for fortuitous conditions. “We place our emphasis on customer service,” says Hennessy. “Quality of the product remains clear. Here talents are developed in the art of hand-splicing wire rope and specialty items like braided slings. I really think this would all make founder Boyd Randall proud as Randall had a true knack for splicing.” Growing into the future Five active steel mills remain along Lake Michigan in Gary today, though they are scaled down quite a bit from earlier days. Hessville Cable is tied in strongly in its business to the steel mills. “Perhaps we are tied in a little more than we should be,” says Hennessy. “The mills are strictly our customers – not the other way around. They use our products for such things as cranes. But few major projects in this area of the country have not had at least some help from us with our highstrength wire rope, chains and fittings, wire rope or synthetic slings.” Hessville Cable is now located at 1601 Cline Avenue in a 60,000 square foot manufacturing facility. (Hessville is a general neighborhood in Hammond, Indiana, a similar situation as The Bronx being part of New York City.) “Our location probably couldn’t be better,” says continued on page 26

continued from page 24 Hennessy. “We’re right off an exit of one of the major thoroughfares of the region. I can pull out of our driveway here at the business and be in downtown Chicago in 20-25 minutes, depending on traffic, of course. The company is very, very well-positioned.” Hessville Cable currently has about 40 employees who are involved in construction of wire rope slings and assemblies, chain slings and assemblies, nylon slings and assemblies, and custom engineered lifting devices. Such products form the majority of their product line and involve the main part of their work force too. They have several divisions within their plant. In addition to manufacturing areas devoted to the assembly of slings and wire rope, the facility also has a sewing shop for custom nylon fabrication, and welding and tool repair areas where they repair anything from electric drills to compressors. This service is open to anyone who is in need of equipment repair. “The dedication and commitment of our workers is shown by the fact that a number of our employees have been with the company for decades,” says Hennessy. “The company remains among the region’s top choices for cable, rope and sling products and is one of the largest and oldest cable companies in the area. We are also a top provider of specialty wire rope. Maintaining high quality is key in all our operations,” says Hennessy. They do not supply much gear to the maritime industry on the Great Lakes any longer. Hennessy explains that those along the Mississippi River are much more involved in supplying ropes and cables than those on the Great Lakes. Hessville Cable equips the construction industry, other heavy industry and industries supporting the steel industry such as tool and die shops, machine shops, equipment manufacturers and even some of the automotive industry. Among Hessville Cable’s clients are northwest Indiana steel mills but their products ship to points across the whole United States as well. Doing what is necessary to stay around Being in a heavily industrialized area means their products find a home in many locations. The company’s products over the changing decades have found uses in building construction, shipping applications, tunnel construction and the earth-moving involved with mining operations. Though they don’t supply directly to coal mines, they do sell to customers around the country that support the coal mines. Coal mines 26
Wire Rope News & Sling Technology April 2011
need their own infrastructure of suppliers for their needs. Hessville Cable’s sling offerings have kept heavy industries such as numerous steel mills and area construction going over the decades. “The steel mills have been up and down with the economy over the years,” explains Hennessy. “Back in the 1980s during the last big recession there were a couple mills that didn’t survive. Now with the current crisis a lot of consolidation has taken place. Anyone who has sold to the steel mills over the years has taken their hard knocks too. We’ve always tried to stay diverse in who we supply as well. But the mills have been in place since the turn of the last century here in Gary. “When it comes to rigging shops, those working with wire rope, chain and other products, everyone pretty much does the same thing,” says Hennessy. “In that regard, I don’t think anybody can say that they do one thing better than anybody else. But I think the thing setting us apart particularly from our competition is our serviceability. We can respond faster to the customers’ needs more than anyone in our area.” Hessville Cable & Sling has an extensive safety training seminar. Bill Kiss, project engineer with Hessville, spends some 50 percent of his time doing training at different customer sites. Hessville tailors safety seminars for various clientele, depending on the need and class size, ranging anywhere from 10 to 200 attendees, and duration anywhere from 90 minutes to 8 hours in length. For testing they have a 600,000-pound horizontal proof tester, a 25-ton vertical proof tester and a five-ton vertical proof tester. Every few years at a customer open house, when people register as they come through the door, they’re asked to take a guess at what the breaking strength of the different items might be. The person who comes closest in predicting that point wins a prize. That’s always a lot of fun. Hennessy has noticed the recent pinch and how much things are off compared to business prior to 2008. But he feels they have fared much better than other rigging shops and those they purchase products from, in many respects. He credits this to their company being aggressive and persistent. “Right up until the end of 2008 we were having a record year,” adds Hennessy. “And even the first three months of 2009 turned out to be fantastic for us. But then it was like someone just turned the facet off. We in turn watched the economy and the sales really close. We had to make cutbacks just like evcontinued on page 28

We’ve worked hard at instilling in our employees ‘total customer satisfaction,’ and everyone has bought into it. All our people go well above and beyond the call for our customers, and you can see it in the pride and sense of accomplishment they show in everything they do. Our customers are able to call us if need be anytime, day or night. Today it’s a necessity, as many businesses run 24/7/365 and you must make yourself available anytime. If for instance, a ladle crane at a steel mill goes down in the middle of the night because the wire rope needs to be replaced, they need that replacement right now – not in the morning.” WRN
Aircraft cable manufacturers, here and now By Peter Hildebrandt
It’s been a good many years since wire rope started showing up on aircraft in early airplanes. (See Untwisting the largely unknown history of aircraft cable, February 2011 issue). During those years, aircraft cable manufacturers have come and gone, and now there are just five U.S. companies who are providing true aircraft cable to the aviation industry.
I
n an effort to find out what’s happening today with aircraft cable, WRN&ST talked to those five manufacturers to learn about the role they play today in the aviation industry. These companies vary widely in their size, makeup and even time in the industry. Oldest among the group is WireCo WorldGroup, which has a number of facilities of various sizes and capabilities all around the centrally-located state of Missouri. Bill Foley, vice president of fabricated products division, points out that though aircraft cable is currently only a very small part of their business, all the diverse areas they’re involved with actually complement each other. With the diversity of the various markets, skills learned in one market can be passed on to others to use that knowledge base. WireCo’s heritage extends back prior to WW II with the founder of WRCA, John P. Barclay Sr. leading the War Production Board. One of the products they’re working on now is the cables for the Orion Space Project, constructing the wire rope cable assemblies that tether the parachute to the space capsule. Working with Airborne Systems of North America the capabilities of both companies will combine to provide the required recovery system. WireCo will utilize the newest aircraft cable, RSQ 4, which was developed two years ago. So the new reaches back to the old with the Apollo Program supported by Macwhyte, the then Kenosha Wisconsin company. WireCo purchased MacWhyte in 1999. At the time of the purchase of MacWhyte, the company was a conglomeration of Broderick & Bascom, and Pacific, which had been purchased by MacWhyte over the years. Foley came to WireCo from MacWhyte and has a background in engineering as well as production. “WireCo continues to invest in equipment and the development of people with out30
standing skills. The individual commitment of our knowledgeable people have made WireCo the dominant organization in the industry,” explains Foley. WireCo is on the Qualified Products List (QPL) MIL 83420 spec for rope, Mil T 781 for fittings and Qualified Manufactures List (QML) for fabrication, with their Kirksville, MO plant AS 9100 accredited. WireCo World Group has the added distinction of providing ISO certifications at all plants, as well as API and Lloyds Registry. WireCo operates eleven manufacturing facilities in the U.S., Germany, Canada, Mexico, and China and employs nearly 2,000 employees worldwide. They supply to all the markets that use wire rope: oil, gas, mining, commercial, structural and many others. “We’re the most diversified wire rope manufacturer in the U.S. and maybe the world,” says Foley. SE Specialty Wire & Cable, LLC, Murrells Inlet, South Carolina supplies stranded cable and wire rope primarily to OEM’s & Commercial Domestic distributors. In June 2010 SESWC, LLC received QPL MIL-DTL-83420 approval of seven (7) part numbers for stainless steel and galvanized steel “flexible wire rope for aircraft control”
Wire Rope News & Sling Technology April 2011
from the Defense Logistics Agency in Richmond, VA and in August 2010 achieved ISO 9001:2008 Quality Management System Certification. “Our Plan is to submit an additional eight (8) wire rope constructions in the first quarter 2011 and continue efforts to qualify all items in the MIL-DTL-83420 listings with a target of January 2013 for completion,” explains James Stanton, operations manager. The company started in August of 2007 and currently employs 9-11 employees depending on production needs and all have previous experience in the wire and cable industry. They currently provide ferrous and nonferrous stranded wire and wire rope constructions used in the automotive, aerospace, industrial, and other diverse OEM markets in such products as trunk, hood and gas cap latch controls, security locks, hoist and winch applications, rescue cables, lanyards, marine rigging, architecture and push/ pull type controls for lawnmowers, golf carts and motorcycles. This firm is the newest of the wire rope companies manufacturing aircraft cable. Many people now working at the firm used to work at others that were MIL-spec qualified, according to Harry Fleming, sales manager. A number of these older firms had since gone out of business, such as Carolina Cable and Strand-flex. “The number of people in this industry had shrunk and SE Specialty realized there was room for another player in the field,” says Fleming. “One reason there are fewer firms in aircraft is they were also manufacturing push-pull cables (big in auto industry), which have gone import. “Aircraft cable has come to be a generic term, meaning any galvanized or stainless steel cable in small diameters. We have inquiries and they ask for aircraft cable and you have to ask them if they want the MIL-83420 or if continued on page 32

continued from page 30 they’re just looking for commercial material. A lot of people, even at the larger companies, are not familiar with the difference. There was a push by at least one manufacturer that tried to not call it aircraft cable if it wasn’t 83420, but just call it commercial or industrial cable, which doesn’t go through anywhere near the same amount of testing. It’s not 83420 unless it’s on the QPL. “We’re still the new guy on the block and are just looking to build up our QPL. In this economy we’re trying to have as many capabilities as possible to meet the needs of companies needing wire rope cable.” Continental Cable, LLC – GBG Industries, Hinsdale, New Hampshire, started manufacturing aircraft cable in the early 1970s. At that point, the large cables had begun to be imported and this was causing the company some problems. So, they headed in the direction of making smaller aircraft cables, according to Brian Nadeau, vice president of business development. “We’re pretty much exclusively in the range of 1/32 to 5/8” in diameter in the cable we work with now,” says Nadeau. “Other countries have tried to copy what’s being done with aircraft cables here in this country and they’re getting
pretty good,” says Nadeau. “But there’s no comparison, really. In the mid-1980s Continental started getting on the QPL for the MIL DTL 83420. “The technology has pretty much stayed the same over the years,” says Gary Preston, COO. “We continue to use wire rope layouts that were done back in the early 1970s.” They do quite a few cables for the Sikorsky Aircraft Corporation, manufacturer of helicopters used in commercial, industrial and military applications. The bulk of the work done at Continental Cable’s New Hampshire headquarters is cable assemblies for the aircraft industry, OEMs and related segments of the business. “Obviously, we use our own wire rope,” says Nadeau. “We manufacture the cable here and purchase the wire elsewhere. Our test bed employs the same machine as that used by other wire rope makers. Ours simply has different specs involved to handle the thinner diameter wire rope used in the aircraft industry.” Continental Cable has their own MIL spec cable. This has its own separate endurance test. Each cable needs to go on this tester and depending upon what the size of the cable is, it has a certain weight placed onto it. The cable
goes over pulleys for a certain amount of revolutions. Then it must be broken. “To be 83420 cable that is actually going on aircraft, it needs to be lubed, certified, have tighter tolerances on diameter; therefore, we are taking things up to a different level with what we refer to as aircraft cable. “The aircraft cable we’re constructing to the 83420 spec can be for all different types of things used on an aircraft such as for the door, which also contains cables and still has to be 83420 cable; we would sell those to people who are making the aircraft door, not necessarily directly to Boeing or such a company as that,” says Preston. Regarding new technology, one of the things Preston finds helpful, is that yearly the various aircraft cable companies get together as an industry at their ACCG meetings. At that time they have opportunities to roundtable different things they’re involved with. It’s also an occasion for people to direct each other on what things they are exploring, and what types of specifications can be added, including what they are going to require on their end in order to meet those specifications. When new technologies are discussed, this is an opportunity for Continental Cable as well as their competitors and their brethren to gather and stay on the same page with one another. “Even though we use those old layouts from the mid-70s, every year we still get together with other cable manufacturers and deal with problems, questions, discussions and any need to make changes,” adds Nadeau. “It’s never a thing where we sit and say ‘it’s been great for 25 years; we don’t need to get together.’ There’s always something to be added or that we might no longer need. This is beneficial to the whole industry. This gathering doesn’t just include the aircraft industry people but also the end terminal manufacturers, makers of fittings. Engineers are there assisting us.” Loos and Company, Pomfret, Connecticut, is a domestic manufacturer of military specification aircraft cable, wire rope, and stainless steel wire. Mike Wallace, vice president of sales and marketing at Loos, worked with a USAF mechanic who was very familiar with cables, on a couple of restoration projects, a B-29 and a P-38 Lightning. Loos was asked to build all new cables for both. They were sent the original drawings of the assemblies and were able to duplicate every one of them with basically the exact same continued on page 34

continued from page 32 cables and terminals. Wallace shares a little bit on each of them: In July of 1942 a squadron of B-17’s and Lightning P-38’s was forced to land on the Greenland Ice Cap during an attempted crossing of the Atlantic. The planes were abandoned and 50 years later, one P-38 nicknamed “Glacier Girl” was recovered from over 250 feet below the surface of the ice. Over time the planes had been covered in snow and ice which made it seem that they had sunk. They retrieved Glacier Girl and began a lengthy restoration program. Loos was contacted to manufacture the new flight control cables during the restoration. She has now been fully restored and made her maiden flight on October 26, 2002. http:// p38assn.org/glacier-girl.htm “Doc,” (B-29 Super fortress 44-69972, Production #10805) was manufactured by Boeing Aircraft Company at Wichita, KS, and delivered to the Air Force on March 23, 1945. “Doc” has four engines with 2,200 horsepower each. The plane has a wingspan that stretches 141 feet, three inches, is 99 feet long and stands 29 feet, seven inches high. When fully loaded, she weighed 141,000 pounds. The plane could fly up to 358 mph, had
a range of 4,100 miles, could carry up to 20,000 pounds of bombs, and held enemy aircraft at bay with 10 machine guns and one 20mm cannon. It took a crew of ten to fly the plane. Doc is being restored to flying form by volunteers in Wichita, Kansas. Loos is proud to have provided the new flight control cables for this historic restoration. http://www.b-29doc.com. Strand Core, Inc. in Milton, Florida has approximately 75% of their work involving the manufacture of aircraft cable. Strand Core’s President, Al Brown, III, echoes what has been mentioned regarding wire rope applications and how little they’ve changed over the years. “Not much drastic has happened in this area, so there is not much need to re-invent,” says Brown. “However, with the aerospace industry moving toward tighter tolerances, higher performances (longer life, break forces, safety margins, etc.), there are constant challenges to meet these demands.” When asked how Strand Core has grown or changed over the years as the aircraft and aircraft industry has changed, Brown notes that with the demand for quality and safety increasing over the last 20 or more years, certified
filtec precise inc.
quality management systems have become an integral part of their every day business. Challenges involved with the manufacture of aircraft cable include the dearth of experienced employees. “There are no schools to go to, to learn the art of manufacturing wire rope,” explains Brown. “The only way to learn is what a rope mill provides for education and training. Since there are only a handful of us left in the US, there are not many people getting trained.” The CEO of Strand Core, Inc., Al Brown, Jr. worked for John A. Roebling and Sons (CF&I) in Roebling, NJ and US Steel from the early 60’s to mid 70’s. These companies were pioneers in aircraft wire ropes. Strand Core’s foundation was built on the history that came from these companies. “I guess what I’d most like people to know about us is that we are a family-owned small business that strives to understand and help navigate the challenges a customer may face; that’s all any business – any good business - can really do. We take a lot of pride in being able to manufacture a quality product at a competitive price with customer support. That’s saying something these days.” WRN

Is there a global market for riggers?
Or is international trade viable only for large companies? By Thomas G. Dolan
As we are now told time and time again, we are all now part of the global economy, interconnected with everyone else on earth if not through our common humanity, at least through our common currency. On a day to day level, it’s difficult to buy a piece of clothing or a dinner wear set which doesn’t state it was made in China, India, or even Bangladesh. But, in terms of doing business, does the global market exist only for governments and giant multinational corporations? Or is there also room for the smaller type of business, such as a rigging shop?
I
n speaking to seven riggers around the country, we found the opinion ranged from what might be expected to some who see a real potential in international trade, and a few who have actually begun making inroads into this new arena. Starting at one end of the spectrum, Alice Jull, president, Van Port Rigging, Inc., Vancouver, WA, says, “The big guys are doing it, but the little guys don’t have the financial background to solicit that kind of business.” Jull maintains that the same dynamics which allows imports to be sold cheaper here would adversely affect the typical small American business from competing abroad. “With more and more imports, you can pick them up anywhere, and we’re selling more of them,” says Jull. “I run a small local company, so the global market has nothing to do with me. I’m just trying to put bread on the table.” “To become global and be able to handle multiple accounts in different countries means we would really have to ratchet up our operations,” says Tom Miller, president, Marcal Rope & Rigging Company, St. Louis, MO. “I think the larger rigging companies on the coasts might be able to do some of this work, but here, in St. Louis, in the middle of the country, with freight always being an issue, the global market is kind of a pipe dream really. I’ve never been one to aim low, but, realistically speaking, being a midwestern rigger becoming a global powerhouse is difficult to do. If someone can find a niche market, and offer what no one else has, that’s one thing, but standard rigging prod36
ucts are made all around the world.” When asked whether, in a general sense, the global market has any effect on him, Miller replies, “It would be foolish and short-sighted to say that we are not affected in some way. Everything can affect something else. When the U.S. economy was going well, that had an effect. When the dollar dropped, that had an effect too. And imported products, especially from Europe and Southern Korea have definitely improved. Their technology has started to catch up. But nine out of ten things we sell are still domestic made. The midwest, as opposed to the east and west coasts, where there is a prevalence of imports, is almost unique in that regard. That’s because we push made in the U.S.A. products and say buying them keep the domestic manufacturers going. We use made in the U.S.A. as a marketing tool.” David Seale, vice president, Sullivan Wire Rope & Rigging, Inc., based in Houston, TX, says that that domestic loyalty is not nearly as common in his area. “As the quality of imports becomes better, more people tend to accept them in their daily business. Then it becomes a question of cost effectiveness, and products become price driven. It boils down to if a customer asks you for a domestic product or one that has the best cost. Most purchases are price driven. So, as suppliers, we have to supply to meet the demand. Right now the total portion of our business is 70 percent import and 30 percent domestic. I don’t foresee that changing in the near future.” On the other hand, Seale says that

there are two situations which have occasionally developed which has allowed Sullivan Wire Rope to ship abroad. The first is when a company headquartered overseas sets up an office in this country and Sullivan wins it as a customer. When a project engineer or other key personnel returns to his home country, this may be a relationship that can be nurtured to ship overseas. The second is when a company based in this country that Sullivan does business with initiates a project overseas. This can also provide a connection. “While not a normal core part of our business, relationships like this have led to overseas orders,” Seale says. Rich St. Pierre, vice president, St. Pierre Chain & Wire Rope, Worcester, MA, is among those who agree there might not be much going on for riggers in the global market currently, but foresees a change in the future. The Internet, of course, is a driving factor in international sales. But there are still many reasons to be cautious about the Internet. “At least through the Internet, the further you go from your base, the more likely you are to be caught in a credit card scam. Many of the Internet shoppers are fraudulent, and we lost $6000 to $7000 through one scam.” St. Pierre says he has learned “to ask for a letter from a bank or a letter of credit, and you’ll likely find you’ll never hear from them again. We received a letter supposedly from a priest in Afr. ica who said he had $50 billion tied up in a bank, and all he wanted was for us to forward him $10,000. Whenever we get something like this through email or fax we turn it over to the FBI.” The Internet has garnered St.

continued from previous page “There is a market, a real market out there,” Boyko says. “But it’s not for everybody. You’re not going to get far with everyday commercially available items you can pick off the shelves. But there is a market for specialty items. You have to be connected to ship internationally. And it takes an effort to train the internal office staff. You have to prepare documents and educate yourself on issues regarding exporting. It’s not an easy thing, and it takes effort.” Also, Boyko cautions, “You have to be careful. I would not rely upon the charm of China, or put all my eggs in that one basket. By nature of their culture, they think differently. You have to understand where they’re coming from. China tends to look at whatever
anyone else is doing, then try to duplicate it through reverse engineering.” Nevertheless, Boyko believes that “though this is a niche, it is a small but important part of our business.” He adds, that, as new frontiers open up, and if trading conditions become more stabilized, that more opportunities will arise. One rigging company which has extensive experience in exporting, and has been doing so for the past twenty years is Certified Slings & Supply, Inc., Casselberry, FL “We do a lot of exporting,” says Jim Flowers, manager of business development, “and, with the economy the way it’s been, we’ve been looking for new markets.

offshore drilling, especially in Brazil. “Overall, there is an appetite in these foreign markets for quality American-made products, originated and fabricated here. These customers want American expertise and know-how.” The foreign attraction for American products, Flowers continues, is because they tend to be both more customized and more mass produced as well as certified. “We are ISO qualified and certified, and this is a critical factor,” Flower says. Much of this has to do with the fact that much of Certified’s exports are for oil rigs. “Two things are going on at once,” says Flowers. “One thing that is driving this is the insurance companies. The company has to know what he is getting, so if something happens there is traceability, which won’t be there if the product came from China. Second, with critical overhead lifting on an oil rig platform you have incredible value at stake. So for those applications you need quality assurance, even though you have to pay more for what you are getting. It’s not like buying tie-downs for farm fencing.” Flowers says his company often works through exporters. This might mean Certified provides for a job it doesn’t even know about, such as a dam project in Pakistan. On the other hand, Flowers suggests that exporters might be a good way for domestic riggers, even in the interior of the country, without access to the coasts, to find foreign markets for their products. What Certified has going for it, however, is location. “Miami is like the capital of Latin America,” Flowers says. “It’s the gateway to the south.” When asked about the obstacles to foreign trade, Flowers replies, “The first is cultural. You’re going in as an American company dealing with an entirely different culture. Then there’s the language barrier.” Yet Certfied has obviously overcome these barriers, as evidenced by the fact that it recently won an award from the International Business Council for being one of the country’s top exporters. When asked the main criteria upon which the award was based, Flowers responds, “It was basically customer satisfaction. We do a lot of investigation on our own, and a lot of trial and error. We talk to a lot of people who have been both successful and unsuccessful in that country. There can be pitfalls to international trade, so you have to do your homework.” WRN
Preliminary steel imports decline 16% in February
Import market share at 18% Based on preliminary Census Bureau data, the American Iron and Steel Institute (AISI) reported that the U.S. imported a total of 1,777,000 net tons (NT) of steel in February, including 1,371,000 NT of finished steel (down 16% and 19%, respectively, from January final data). Annualized total and finished steel imports in 2011 would be 23.4 and 18.4 million NT, respectively, each down 2% vs. 2010. Finished steel import market share in February was an estimated 18% and is 20% through 2 months of this year, a slight decline from the 21% for full year 2010. In February 2011, compared to the month before, imports of reinforcing bars were up 63%; they are up 79% year-to-date. Other major products with significant year-to-date import increases vs. the same period last year include oil country goods (up 90%) and cut length plate (up 84%). In February, the largest volumes of finished steel imports from offshore were from South Korea (183,000, down 15%), Japan (123,000 NT, down 5%), Turkey (70,000 up 96%), Germany (64,000 NT, down 34%) and Australia (53,000, down 29%). For the first 2 months of 2011, the largest offshore suppliers were South Korea (396,000, up 59%), Japan (252,000 NT, up 29%) and Germany (162,000 NT, up 150%). Below are charts on estimated steel import market share in recent months and on finished steel imports from offshore by country.
American Iron and Steel Institute supports President’s priorities for boosting manufacturing; urges administration to adjust regulatory burden, take tougher stance on China trade
Supporting President Obama’s challenge to invest in America’s future issued during comments delivered to the U.S. Chamber of Commerce, the American Iron and Steel Institute (AISI) agreed that American workers nationwide will benefit if the nation is able to increase exports and rebuild America’s infrastructure. “We endorse the President’s call to to put more people to work rebuilding crumbling roads and bridges,” AISI President and CEO Thomas J. Gibson said. “The steel industry agrees this should be an immediate focus and we

are urging that Congress approve a new multi-year surface transportation act that will provide an adequate level of funding for significant infrastructure projects with an emphasis on highways and specifically bridges. This will not only make America a better place to do business, it will also put Americans back to work in high-paying jobs.” Gibson said the Department of Transportation reports that every $1 billion federally invested in highway capital supports nearly 35,000 American jobs. “We are also on record supporting the President in his goal of doubling U.S. exports by 2015,” Gibson said. “In that regard, we agree with his desire for ‘an economy that’s based on what we make and sell around the world.’ But to achieve that, we must have a level playing field for American manufacturers. The most egregious competitive disadvantage we face at present is China’s undervaluation of its currency by as much as 40 percent, which directly undercuts U.S. manufacturers and is costing valuable American jobs. Our nation must get tough with China on currency and other abusive trade prac-
tices before we can achieve this laudable goal.” Gibson said the President is on the right track with his stated goal of eliminating ‘outdated and unnecessary regulations’ that hamper economic growth. He said AISI believes, however, that the Environmental Protection Agency’s (EPA) regulation of greenhouse gas emissions from stationary sources will have to be addressed by Congress. “These regulations will negatively impact American manufacturing jobs by adding to our domestic regulatory burden even while emissions continue to increase from sources in nations without similar regulations,” Gibson said. “Members of Congress in both the Senate and the House of Representatives understand that unilateral climate regulation will not result in any emissions reductions if production is merely shifted offshore. Perversely, it will only result in increased emissions as we import steel and steel-containing goods from economies that are less efficient than our own. We look forward continued on next page

continued from previous page to working with Congress to push back these misguided regulations that will simply shift American jobs and emissions to unregulated nations.”

Gibson, AISI president and CEO, said. “We urge that WTO approve this request and move forward to assemble a panel.” Gibson said that, according to USTR, China did not follow WTO requirements in numerous aspects of the antidumping and countervailing duty proceedings in this case, which in turn has led to serious and unjustified restrictions on exports of American steel. He noted that, in contrast to the United States – where trade remedy procedures are transparent, WTO-consistent and provide due process for all parties — China has engaged in a gross abuse of its trade remedy procedures by denying due process and access to key information and by using WTO-inconsistent
methodologies. “We believe that China’s gross abuse of antidumping and countervailing duty procedures must be brought under WTO scrutiny in order to achieve clarity and an equitable solution to this unresolved dispute,” Gibson said. “This failure of China, once again, to live up to its WTO obligations has hindered U.S. steel exports and put valuable American jobs at risk.”
FeMET initiative accepting proposals for 2011–2012 design and curriculum development grants

AISI commends members of Congress for reintroduction of currency reform legislation
American Iron and Steel Institute calls on Congress to support action immediately The American Iron and Steel Institute (AISI) commended Sen. Sherrod Brown (D-Ohio), Sen. Olympia Snowe (R-Maine), Congressional Steel Caucus Chairman Tim Murphy (R-Pa.), Ways and Means Ranking Member Sander Levin (D-Mich.) and Rep. Tim Ryan (D-Ohio) for introducing the Currency Reform for Fair Trade Act of 2011. Last September, the House passed similar legislation by an overwhelming vote 348-79, but it was not taken up during the Senate’s lame-duck session. “We greatly appreciate the tremendous leadership shown today by the sponsors of the Currency Reform for Fair Trade Act. This bill has wide bipartisan support as shown by both the overwhelming vote in favor of it in the last Congress and the large number of
original co-sponsors committed to its reintroduction in the 112th Congress,” AISI President and CEO Thomas J. Gibson commented. “The Currency Reform for Fair Trade Act is common sense legislation that adds no additional cost to the federal government but does provide the U.S. with a legal tool to use in addressing the unsustainable trade balance we have with China and its built-in export subsidy, which undercuts American manufacturers and costs valuable manufacturing jobs. The bill would give U.S. manufacturers the ability to use the existing countervailing duty law to obtain a remedy for injury caused by goods benefiting from a currency manipulation export subsidy. “China Inc. continues to flagrantly disregard its WTO commitments by deliberately undervaluing its currency by as much as 40 percent to gain an unfair trade advantage for its manufacturers. Last Friday, the Obama Administration sidestepped another opportunity to cite China as a currency manipulator. We cannot keep giving China a free pass on this critical issue. It’s time that Congress directly address these protectionist and trade-distorting currency practices and make China play by the rules.” continued on next page

Steel Industry urges action by U.S. Trade Representative Ron Kirk against raw material export restrictions
In a letter sent to the U.S. Trade Representative (USTR) Ron Kirk, the American Iron and Steel Institute (AISI), the Steel Manufacturers Association (SMA), the Specialty Steel Industry of North America (SSINA) and the American Scrap Coalition (ASC) urged Ambassador Kirk to take action to address the growing imposition of
restraints on exports of raw materials used in steel making by a number of major steel producing countries. These raw material export restraints give foreign steel producers an unfair artificial advantage in international competition at the expense of the U.S. steel industry. In the letter, American steel industry representatives urged the USTR to lead the global trading community in addressing the issue of restraints on exports of raw materials, pointing to India’s recent quadrupling of export duties on certain types of iron ore, and Russia’s
announcement that it will limit exportation of iron and steel scrap through only certain ports. The letter also noted that China has announced further restrictions on exports of fluorspar and refractory bauxite, despite an ongoing WTO challenge to such restrictions. The letter notes that while some export restrictions – such as those imposed by China – are in clear violation of WTO rules, some of the other restrictions – for example, export duties – may not be subject to uniform international disciplines. The letter recommended that export duties that do not appear to be subject to adequate WTO or other disciplines, should be a priority of international negotiations. “This may require action at both the multilateral and bilateral levels,” the letter stated, “and it will also require greater ambition and effort than contemplated with the current Doha initiative on transparency,” the letter concluded. For a complete copy of the letter, go to our web site at www.steel.org/~/media/ Files/AISI/Public%20Policy/Letter-tradeUSTRreRawMaterials.ashx.
Steel industry responds to President Obama’s call to improve energy efficiency in buildings
Steel provides retrofit opportunities to reach ambitious energy-saving goals Responding to President Obama’s Penn State address calling for businesses to improve energy efficiency in commercial buildings across the United States, the steel industry announced it has the products and technologies to help building owners achieve these long-term goals. “The President has laid out an aggressive plan for retrofitting commercial buildings with energy-efficient upgrades,” Lawrence W. Kavanagh, president of the Steel Market Development Institute (SMDI), said. “We can help businesses meet this challenge with steel technologies and products that are durable, cost-effective, provide long-term energy savings, and are available now. “Steel offers energy-saving solutions for many building components,” Kavanagh said. “An example is cool metal roofing and wall products that help reduce building energy consumption by lowering cooling loads. Reflective metal roofs can save up to 40 percent in building cooling energy costs and are excellent options for commercial retrofit applications. In many retrofit applications, metal roofing can be efficiently installed with above sheathing 52

ventilation (ASV), which allows heat to dissipate through the ridge vent in hot weather while acting as an insulating layer when it is cold. With ASV, steel roofs can contribute to a 30 percent reduction in heat gain through the roof.” Kavanagh explained that the steel industry, partnering with manufacturers and installers, continues to invest in innovative technologies to improve the energy efficiency of building cladding products. Steel roofing and siding offers an excellent base to provide a building with electrical generation and innovative solar thermal systems. Metal roofs provide the optimal foundation for photovoltaic installations, since the roof can be expected to last longer than the PV system it supports. New technologies are being developed with the potential to allow the PV generating system to be painted directly on the metal roofing substrate. Wall and roof solar heat recovery systems can be integrated with steel cladding and used to provide air, water, or process heating needs. In addition to these direct energysaving benefits, steel roofing and wall cladding contribute to an overall reduction in environmental impact. Steel construction materials in retrofit ap-
plications typically generate credits in green building certification programs and reduce the building’s carbon footprint. Steel cladding is durable, offering long-term resistance to weather, including wind, hail, ice, and snow. Commercial metal roofs have been in service in excess of 30 years, and painted metal roofs are credibly warranted for a minimum of 30 years. Steel is produced using recycled materials and is fully recyclable at the end of its useful life. Reflective metal roofs can help reduce urban heat island effect. As an added benefit, steel roofing is lightweight, so a retrofit steel system can often be installed over an existing roof covering, reducing landfill waste. “Wall and roof cladding products using steel can play a key role in achieving the President’s energy objectives by providing an attractive, durable retrofit alternative for the commercial building market that also reduces overall environmental impact,” Kavanagh said. For more information on the benefits of cool metal roofing, visit www.coolmetalroofing.com. The Steel Market Development Institute, a business unit of the American Iron and Steel Institute (AISI), grows and maintains the use of steel through
strategies that promote cost-effective solutions in the automotive, construction and container markets, as well as for new-growth opportunities in emerging steel markets.

Gibson, said. “Particularly noteworthy is the fact that the Commerce Department decided, appropriately, to apply the antidumping order broadly to all Chinese producers, not just the specific Chinese producers found to be circumventing. This is a clear victory for U.S. plate producers. Commerce will now collect cash deposits on all Chinese boron-added plate, unless the producer can clearly verify that the product meets very specific additional testing requirements showing that the boron addition actually was added to improve the characteristics of the steel to meet required specifications.” “We are also pleased that Commerce is going to move forward swiftly on a quick schedule to render a final determination,” Gibson said. He said it is also positive that the additional AD duty collection begins immediately, and cash deposits are actually required retroactive to April 2010.

AISI releases final report of the Technology Roadmap Research Program describing 47 R&D projects valued at $38 million supported by the steel industry and U.S. DOE
The American Iron and Steel Institute (AISI) has released the Final Report of the Technology Roadmap Research Program for the Steel Industry—an account of collaborative R&D efforts jointly funded by the steel industry and the U.S. Department of Energy (DOE). The report details 47 R&D projects valued at $38 million for research into all areas of steelmaking conducted over a 10-year period. The Technology Roadmap Program (TRP) was designed to develop new technologies directed at joint government and industry goals—saving energy, increasing competitiveness and reducing emissions to the environment. The program results provided significant energy and CO2 savings in steel manufacturing. More importantly, even greater savings are being realized by the users of steel products. For example, several advanced high-strength steel projects resulted in lightweight automotive designs—in turn reducing gasoline consumption and greenhouse gas emissions.
Wire Rope News & Sling Technology April 2011
“The TRP Final Report is the culmination of a decade of collaborative R&D work that defined a pathway for achieving the North American steel industry’s established energy and environmental objectives,” AISI President and CEO Thomas J. Gibson said. “The results speak for themselves. We have achieved a 30 percent energy intensity reduction since 1990. To make future reductions of this magnitude, we are exploring ‘breakthrough technologies’ and must have continued collaboration between industry and government through successful partnership programs like TRP.” Breakthrough technologies are those that are significant departures from current technology. The TRP began the steel industry’s efforts in this area. Several projects begun under TRP are continuing and have the potential to substantially reduce CO2 emissions: Paired Straight Hearth Furnace (McMaster University); Hydrogen Flash Smelting (University of Utah); and Molten Oxide Electrolysis (Massachusetts Institute of Technology). AISI and its members are working to continue partnering with DOE to develop these next generation processes. TRP supplemented the in-house R&D

FABTECH shifts show dates to November 14-17
Increased automation and demand for floor space fuels date change. FABTECH show management announced a shift in dates for FABTECH 2011. North America’s largest metal forming, fabricating, welding and finishing event will now open on Monday, November 14 and run through Thursday, November 17 at Chicago’s McCor-
mick Place. The show originally was scheduled to begin on Sunday. The change is due to a number of factors, including an increase in exhibitor participation and demand for larger booth spaces. In addition, exhibitors are making plans to display highly automated machinery on the show floor. This type of equipment requires a minimum amount of set-up time and the new dates will provide an additional move-in day. “We are pleased to hear exhibitors plan to demonstrate more never-beforeseen machinery, high-tech equipment and advanced technology at FABTECH 2011,” said John Catalano, FABTECH co-show manager. “We feel the date adjustment will better accommodate our exhibitor set-up needs and demonstrates our commitment to ensuring both exhibitors and attendees have the best show experience possible.” The 2011 event is expected to draw 30,000 attendees and 1,200 exhibiting companies covering more than 450,000 net square feet of floor space. Buyers and sellers from around the world will come together to exchange products and services, network with peers, problem solve and discover new products. continued on next page

SC&RA offers free comprehensive crane accident investigation guide
The Specialized Carriers & Rigging Association (SC&RA) has published its Crane Accident Investigation Guide after two years of planning and preparation by the Association’s Crane & Rigging Group Safety Education & Training Committee. Because SC&RA members typically lift and position oversize objects, frequently at great height and with tight tolerances, the possibility for severe injury or major property damage can never be overlooked. Available as a free resource exclusively to SC&RA members, the new 10-page guide is offered in PDF format, enabling it to be reprinted very easily. The primary focus is on the determination of the facts surrounding the incident and the lessons that can be learned to prevent future similar occurrences. The easy-to-use checklist format covers many considerations unique to the crane & rigging industry. For example, among the 15 types of accident description listings are crane overturned, boom collapsed, load fell, and wire rope/cable broke. Other categories in the comprehensive guide include types of bodily injury and property damage; time of accident; weather; lighting; type of job; type of project; nature of work; property ownership; legal property status; load description; weight and how determined; training of lift director, crane operator and other key personnel; rigging and equipment information; equipment setup; lift engineering; types of reports prepared as a result of the accident; contractual risk transfer; subrogation; and other factors subject to further analysis and review by qualified experts.

The award is named after Samuel Plimsoll (1824-1898) who was a member of Parliament in Britain and tirelessly fought against unsafe maritime industry practices. “The Samuel Plimsoll Award honors those whose work has made life safer and more productive for modern day seafarers,” says John Gormley, Jr., editor of Professional Mariner. Since the introduction of their flagship product AmSteel®-Blue in 1996, Samson has been making the commercial marine industry safer. This product is, size for size, as strong as steel wire but 1/7th the weight, making it much safer for crews to handle and significantly reducing back and hand injuries.

Unitex Group USA update
Unitex USA is part of the Unitex Group, a global corporation headquartered in the Netherlands. We are a privately owned corporation, with ownership that has a very long term strategic plan for our company. We have four manufacturing locations in Europe, and one manufacturing location in China. We are very proud of our product portfolio, and believe that our global sourcing and manufacturing capabilities bring great value to our customers. In the middle of 2010, our owners decided that Unitex needed a much greater presence in the United States in or-
der to service our increasing demand. As a result, a search was initiated for property in which to locate not only a webbing manufacturing facility, but to also relocate our existing fabricating and distribution business. We found the perfect location for our company in South Carolina, and finalized the purchase of our facility in October of 2010. We believe that our new location, along with the resources that will be included here, will allow Unitex to offer our customers a level of service that Unitex has not previously attained. Our goal is to provide every customer with a competitive advantage by quickly filling orders with the best products available at the most competitive prices in the market. Our new facility will also provide us with the capability of manufacturing and distributing custom made slings with minimal leadtimes, thereby helping our customers secure orders quickly and efficiently. Unitex is now in the midst of relocating our operations from Dallas, Georgia, to Piedmont, SC. We are moving both equipment and inventory, and shipping orders to customers from two locations. We expect this transition to be completed no later than Friday, January 28. We are excited about our new
location, and proud to be creating jobs in South Carolina.

Microstructured molding tools will impact manufacturers of products that could benefit from enhanced surface capabilities. Created as square or custom inserts for injection or compression molds, the innovation adds several capabilities to any molded product: superhydrophobic, reduced friction, reduced fluid drag, increased heat transfer and many others. This approach reduces microstructure manufacturing cost by 83 percent to 98 percent. Developed by Hoowaki, microstructured tooling has been available since the spring of 2010. Programming light with quantum dots is an innovation that promises not only to change the way things are manufactured, but also change the way we light our homes and offices.Quantum dots are nanoparticles of a semiconductor material that range from 2 to 10 nanometers in diameter. The ability to control the size of a quantum dot enables a manufacturer to determine the color of light emitted. Quantum dots are currently providing brighter images, lower power consumption and improved color purity for electroluminescent displays. Companies manufacturing quantum dot-enabled products include QD Vision and Weinberg Medical Physics. Controlled through a Web-based application, a remote-presence robot allows a telecommuting worker to remotely attend meetings, drop into the offices of colleagues and otherwise collaborate with people in another office. With cameras in the eyes to capture video, speakers and microphones to relay sound and a laser pointer “finger,” the user can see what the robot sees and direct it around by using a computer’s arrow keys. Companies such as Procter & Gamble are using these remote-presence robots to increase the efficiencies of teams working across the world. Ten times stickier than Velcro® and reusable gecko-inspired glues, Super Velcro is an extremely strong adhesive that comes apart when heated. Using 62
shape-memory polymers, General Motors researchers have created a product that allows a strong but alterable bond that replaces liquid adhesives requiring lengthy oven curing, which consumes a lot of energy, or foam tapes that do not provide high adhesion strength. Super Velcro is currently being used for interior and exterior automotive trims with potential applications for furniture, toys and buildings. In reviewing submissions for the Innovations That Could Change the Way You Manufacture, the committee also highlights an Innovation Watch List. These technologies are showing great promise but, as yet, are unproven in the manufacturing setting. This year’s list includes: • Continuous-flow microreactors • Dip-pen nanolithography • Green cement • Large-format ceramic batteries • Laser heating in a diamond anvil cell • Metamaterials • Self-assembling vehicles • Synthetic cells “Because most people use common, everyday products that are frequently outsourced, they think that manufacturing in America is dead,” said Fritz. “Innovations like those identified today should be a reminder that American manufacturing has moved beyond the production of commodities and is one of the most technologically advanced sectors of our economy.” The Innovations That Could Change the Way You Manufacturewill be a central focus of the Manufacturing Velocity: SME Annual Conference scheduled June 5-7, 2011, in the suburbs of Seattle. The conference brings together manufacturing professionals and leaders from throughout North America and beyond who are interested in innovations and exchanging ideas in one place.

Lifting apparatus with compensation means Pat. 7,878,347 U.S. class 212/223 Int. class B66C 23/02 Inventor: James J. Alday, Honeoye Falls, NY. Assignee: Gorbel, Inc., Fishers, NY. This patent presents a lifting assembly such as a jib crane or similar apparatus having an articulated arm assembly and a flexible means for connecting a load to an actuator. The lift arm assembly forms an articulated cantilever boom, which is extensible so as to traverse a suspended load within a work cell area. The lift arm assembly further includes a first and second member pivotally connected to one another whereby an inclined plane (e.g., a cam) at the pivot point of the articulating arms provides a vertical displacement of the secondary arms thereby moving the distal end of the secondary arm to counterbalance inherent forces acting on it. Referring to figure 1, depicted in a perspective view therein is an exemplary articulated arm lift 20, a Gorbel EasyArm. TM. lift, having a support column 20 and primary and secondary articulated arms 24 and 28, respectively, connected via pivots. The actuator or winching device 30 is located on the proximal end of primary arm 24, and controls the line or
wire rope 36 that is connected to a user control 40 and load 50 suspended from a hook or other end-effector associated with the control. There are at least two forces that produce the aforementioned objectionable circumstances as a result of the use of a cable guide pulley 32 adjacent to the pivot point 34 between the arms. One such force is the result of “droop� that occurs when a load is applied to the end of the rope 36, thereby creating a moment relative to the column and the position it is attached to the floor. This obviously varies with the location of the load relative to the column, and the height of the column. While moving the secondary (outermost) arm 28 from an in-line position relative to arm 24, the cable moves toward and contacts the pulley, thereby producing a radial force having a tendency to move the secondary arm toward an in-line position with the primary (innermost) arm. Such forces may prevent the secondary arm from remaining in a stationary position. continued on next page

counteract or negate the forces that act to prevent movement of the load and/or preclude put-n-stay functionality. The various embodiment disclosed are intended to mitigate or reduce adverse forces that compromise a uniform and sustained effort by the operator to initiate the motion of arm/load, to sustain the arm in motion, and to assure the arm remains in a put-n-stay position when an operator-applied horizontal force to the load 50, or controller 40, is removed. The embodiments contemplate the use of mechanical cam or similar means to adjust or compensate for such forces. Controlled and uniform motion of the articulated arms is compromised by a combination of forces. One force results from the cable 110 consistently pulling the secondary arm 104 towards an equilibrium position, this force results from the tension on the lifting cable, particularly when a load is suspended from it, and the offset of the cable from the center-
Figure 3: Partial top-views of the articulated arm pivot of figure 2, positioned at about a 45 degree angle.
As the secondary arm is pivoted further relative to the primary arm, the cable 36 increasingly becomes wrapped about or engages a pulley 32. Consequently, as the cable wraps about the circumference of the pulley, the moment force increases thereby producing a radial torque between the two arms. In addition, the load 50 is lifted slightly as direct function of the cable being wrapped about the pulley, thereby causing additional work as the suspended load is moved. The combination of the various forces results in a potentially imbalanced condition. In order to enable a free-swinging, articulated arm lift, where the various interactive forces are reduced or otherwise controlled, the disclosed embodiment contemplate means to

line of the pivot point. Referring for example to figures 2 and 3 the clevis or pivot pin 106 defines the center of the pivot and any offset of the cable from such a position, as shown in figure 3, produces a moment between a cable tangent point on pulley 108 and pin 106. Another force is the result of the load being vertically displaced as a function of arm pivoting and wrapping of the cable about the pulley when the arms are moved relative to one another. Yet another force is derived from the bending moment of the articulated arms and an associated column or support structure. The offset, denoted as distance “r� in both figures 3 and 4 represents the distance measured between the cable and the pivot point. This radial moment, in conjunction with wrapping of the cable 110 about pulley 108 tends to resist pivoting of the secondary arm relative to the primary arm, as well as, potentially causing the secondary arm to move after being released by the operator. Reference is now made to figures 2-4, where various positions of primary and secondary arms 102
and 104 are illustrated according to the following stages of movement: Stage 1—(aligned) In figure 2 cable 110 passes substantially over the centerline of arms 104 and 102, therefore there is no offset and accordingly no force moment or cable wrapping about pulley 108 is evident. However, a moment caused by the load 116 suspended at the distal end of secondary arm 104 is at a maximum, therefore the arms are deflected downward. In some embodiments, due to the cable tension caused by the load, the arms are not inclined to freely articulate from the generally aligned configuration of figure 2 without a considerable sidewise force to “snap” them off their respective centerline. Stage 2—(arms @ ±45°) As seen in figure 3, a minor moment force develops as the cable moves off-center and begins to make contact with the outer circumference of pulley 108. Additionally, as the angle between the arms decreased (from a maximum of 180° when aligned), the load is moved closer to the column or support, thereby reducing the bending moment. Stage 3—(arms @ ±90°) At this point, shown in figure 4, cable 110 has now completely moved across the open space between arm 104 centerline and the circumferential surface of the pulley 108. Notably cable 110 is increasingly wrapped about the radius of pulley 108, thereby progressively raising the vertical position of the load. Stage 4—(arms @ ±120°) As represented in figure 5, cable 110 continues to cause a larger moment (deflection from the center of the arms) as it wraps about the circumference of the pulley. Additionally, the wrapping about pulley 108 further causes cable 110 to shorten thereby further raising load 116 —resulting in additional work=(force)(distance). Stage 5—(fully retracted) The cable is now substantially wrapped about approximately one-half of the pulley circumference and the maximum radial torque is present, as well as the maximum amount of work expended to attain the load position. However, the moment caused by the load is at a minimum, therefore, the arm deflection or droop is also near a minimum. Ground anchor Pat. 7,887,263 U.S. class 405/259.1 Int. class E21D 20/00 Inventor: Miles Edward Moffat, Christchurch, NZ. Assignee: Miles Edward Moffat, Christchurch, NZ. This patent presents a cable guide mechanism configured to be releasably attached to a shaft, which includes a body portion, an indent or groove and a protrusion, characterised in that the indent or groove is located on the opposite side of the body portion to the protrusion, and is dimensioned and configured to releasably retain an inside edge of a first distal end of a loop which is attached to a terminal end of a cable; the protrusion is tapered with its widest section directly opposite the indent or groove; the linear distance between the bottom of the indent or groove and the widest section of the protrusion is sufficiently close to the inside length of the loop that in use the first distal end of the loop cannot climb out of the indent or groove; the shaft is configured to freely rotate co-axially inside the cable guide mechanism. Referring to figure 6, a ground anchor 100 is shown. The ground anchor 100 has a shaft 10. The shaft 10 may vary in length, as indicated by the break in the shaft indicated by arrow 11. Located at the first distal end of the shaft 10 is an extension in the form of an auger 12 on a solid shaft portion 24, for assisting insertion of the ground anchor 100 into the ground (not shown). The auger 12 is attached to the shaft-10 via the shaft portion 24 extending from the auger 12 into the

shaft 10. Preferably, the top distal end of shaft portion 24 has a tapered square shape, which slots into a portion of shaft 10, which is cylindrical. It would be appreciated by a person skilled in the art that in this configuration shaft portion 24 will then be held in place within shaft 10. Located at the second distal-end of the shaft 10 is a handle 13. The handle 13 is a metal tube attached to the shaft 10 via a rigid loop 14, through which the handle 13 is inserted. Also located on the shaft 10 of the ground anchor 100 is a cable guide mechanism 200. The cable guide mechanism 200 has a body portion, as indicated by line 15, and two protrusions, a first protrusion 16 and a second protrusion 17. Also attached to the ground anchor 100 is a wire cable 18. The cable 18 has two loops (indicated by lines 19 and 20 respectively) at each end of the cable 18. The loops 19 and 20 are retained by gripcontinued on next page

ping devices 21, which receive and retain a length of the cable 18 in a loop. The loops 19 and 20 have a teardrop shape, with a wide body portion (indicated by arrow 26) and a narrow portion (indicated by arrow 27). The cable 18 is attached to the ground anchor 100 via the first loop 19 of the cable 18, which encloses around the cable guide mechanism 200 of the ground anchor 100. Figures 7, 8, and 9 show various views of the cable guide mechanism 200 independent to the ground anchor 100. Shown in these figures is the body portion 15, the first protrusion 16 and the second protrusion 17 of the cable guide mechanism 200. As shown in these figures, the body portion 15 is in the form of a hollow tube. As shown in figure 7, the first protrusion 16 is indented (as indicated by arrow 22) from the first distal end of the body portion 15 of the cable guide mechanism 200. The second protrusion 17 is tapered, with the widest end (as indicated by arrow 23) of the second protrusion 17 being located at the first distal end of the body portion 15 and the narrow portion (as indicated by line 25) being located towards the second distal end of the body portion 15. Figure 8 shows a plan view of the top of the cable guide mechanism 200. The body portion 15, the first protrusion 16 and the second protrusion 17 are all shown. Shown in this figure the cable guide mechanism 200 is enclosed around the shaft 10 and/or shaft portion 24 of the ground anchor 100 and the auger (not shown) respectively. The first loop 19 of the cable 18 surrounds the outside of the cable guide mechanism 200. As shown, the wide portion 26 of the loop 19 sits within the indent 22 of the first protrusion 16, while the narrow portion 27 of the loop 19 sits around the second protrusion 17. Figure 9 shows a detailed view of the cable 18 and cable guide mechanism 200, while the cable guide mechanism is inserted into the ground 30. Before the cable 18 and cable guide mechanism 200 are inserted into the ground, the loop 19 of the cable 18 sits at a 90째 angle to the axis of the body portion 66
Wire Rope News & Sling Technology April 2011
15, in the orientation indicated by arrow 201. When the ground anchor 100 is twisted into the ground 30, cable 18 is pulled through the hole 31 that is formed by the auger 12. The narrow portion 27 of the loop 19 moves towards the shaft 10, in the direction indicated by arrow 32, while the wide body portion 26 of the loop 19 is held at the first distal end of the body portion 15 of the cable guide mechanism 200. When the ground anchor 100 is fully inserted into the ground 30, the cable 18 then runs in a position substantially parallel to the shaft 10 of the ground anchor 100, at an orientation as indicated by arrow 202. By allowing the cable guide mechanism 200 to rotate independently (or remain stationary in relation to) the shaft 10, and having the particular configuration of the two protrusions 16, 17, prevents the cable 18 from wrapping around the shaft 10, while the ground anchor 100 is inserted into the ground 30. Once the ground anchor 100 is at a depth that can sufficiently hold the vehicle (not shown), the handle 13 is removed and the second loop 20 of the cable 18 is attached to the vehicle (not shown) or an additional cable (not shown) that is then attached to the vehicle. Once the cable 18 is attached to the vehicle (not shown), the cable 18 can be winched pulling the vehicle forward. When a load is put on the cable 18, the cable 18 will pull in the direction, as indicated by arrow 33, towards the vehicle (not shown). This will force the cable 18 through the ground 30, in the direction indicated by arrow 34. Given that the ground anchor 100 is sufficiently anchored in place, this provides enough tension to prevent the ground anchor 100 from moving out of position. This is achieved as the cable 18 acts to pull the ground anchor 100 substantially horizontally through the ground rather than at a vertical angle out of the ground. Self contained integrated mooring system Pat. 7,891,309 U.S. class 114/230.2 Int. class B63B 21/00 Inventor: Frederick R. Driscoll, Pembroke Pines, FL., PierrePhilippe Beaujean, Fort Lauderdale, FL., John Charles Frankenfield, Greenacres, FL. Assignee: Florida Atlantic University, Boca Raton, FL. This patent presents a self contained integrated mooring system configured to contain items within a payload container in a water body. The self contained integrated mooring system may include components for conveniently collecting and storing the components of the self contained integrated mooring system. The self contained integrated mooring system may be formed from the payload container, a mooring line handling and storage module, an anchor and a system container in a single system that eliminates having to work and rework anchor lines on a deck of a boat. As shown in figure 10, the payload 12 may be formed from a container adapted to contain the payload components, which may be, but is not limited to batteries, electronics, a transducer for underwater acoustic communication and positioning system, and other appropriate items. In particular, the payload container 12 may include an internal cavity 20 configured to retain the payload components. The internal cavity 20 may have any appropriate size and shape, which is dependent upon the size of the components and the particular application for which the self contained integrated mooring system container 10 is designed. The system container 18 may also include one or more lids 22, which may be a reusable lid, attached to the system container 18 to seal one or more openings 24 in the payload container that facilitates access to the internal cavity 20. The lid 22 may include seals to seal the internal cavity 20 to prevent water intrusion when the system container 18 is deployed in

water. The lid 22 may be multipurpose and include antennas 78. The system container 18 may include a handle to facilitate handling of the container 12. The system container 18 may be formed from any appropriate material or combinations of materials, such as, but not limited to, stainless steel, aluminum, fiberglass, epoxy, foam, and plastic. The system container 18 may also contain or be attached to a mooring line handling and storage module 14 that is configured to contain a mooring line 28. The mooring line handling and storage module 14 may be in communication with the payload container 12 or other components. The mooring line handling and storage module 14 may be formed from one or more spools 30 configured to store the mooring line 28. The mooring line 28 can include, but is not limited to, plastic rope, wire rope, armored cable with internal optical and electrical conductors, monofilament line, chain, fishing line and any combination thereof. The mooring line 28 may be formed from diameters, such as about 1/8 of an inch, which are much less than conventional anchor lines because the mooring line handling and storage module 14 contains the line and prevents the line from tangling, which is typical of unconfined, thin diameter lines. Use of the smaller diameter lines by the mooring line handling continued on next page

and storage module 14 enables longer lines to be used, thereby permitting the self contained integrated mooring system 10 to be deployed in deeper water. The spools 30 may be supported by a single shaft 32. The shaft 32 may be attached to a driver 34, such as a motor, an electric motor, a mechanical winder, or an electro-mechanical winder, or handle 36, or both, for rotating the shaft 32 and spools 30, to retrieve the mooring line 28 onto the spool 30. One or more winder receiving adapters 58, as shown in figure 11, may be coupled to the shaft 32 supporting the spool 30. The winder receiving adapter 58 may be adapted to be attached to a drill or other mechanical or electrical system to rotate the spools to retrieve the mooring line. A drill, such as, but not limited to, a cordless drill, or other appropriate rotary device may be used to rotate the shaft 30 to retrieve mooring line 28 and store it on the spool 30. The mooring line handling and storage module 14 may be fixedly attached to the payload container 12 or attached via a line. The mooring line handling and storage module 14 may be attached to the system container 18 or may be a stand alone unit not attached to any of the components of the self contained integrated mooring system 10. In at least one embodiment, the mooring line handling and storage module 14 may be attached to a head 38 of the payload 12 in a position enabling the mooring line 28 to be paid out of the mooring line handling and storage module 14 and attached to the anchor 16. The mooring line handling and storage module 14 may be attached to the head such that the mooring line handling and storage module 14 is in proper orientation to prevent the payload 12 from being damaged when mooring line 28 is being paid out or retrieved and to reduce torque on the payload 12. In at least one embodiment, a sleeve 62 extending from the mooring line handling and storage module 14 extends partially over the payload 12. Attaching the mooring line handling and storage module 14 directly to the payload 12 reduces the overall size of the system. In at least one embodiment, the payload 12 may include a plurality of studs 64 that may be 68
Wire Rope News & Sling Technology April 2011
inserted through orifices in the mooring line handling and storage module 14. The mooring line handling and storage module 14 may be retained in position with clips 66 attached to grooves in the studs 64. The mooring line handling and storage module 14 may be attached in other appropriate ways as well. The mooring line 28 may be fed through a guide at a base 40 of the payload 12 to keep the payload container positioned upright when deployed. As shown in figure 12, the mooring line handling and storage module 14 may also include a locking mechanism 68 that is configured to prevent the spool 30 from rotating such that after an amount of mooring line 28 is paid out, the spool 30 may be prevented from being rotated. In one embodiment, the locking mechanism 68 may be formed from a latch 70 configured to slide within a channel 72. The latch 70 may be slid into contact with the shaft 58. In one embodiment, the shaft 58 may be generally square, and the latch 70 may be configured to engage the shaft 58 to prevent the shaft 58 from rotating. The latch 70 is held in place with a set screw 74. The locking mechanism 68 may be formed from other appropriate systems as well and is not limited to this particular configuration. Steerable paravane system for towed seismic streamer arrays Pat. 7,881,153 U.S. class 367/18 Int. class G01V 1/38 Inventor: Jan Erik Stokkeland, Heggedal, NO., Ole-Fredrik Semb, Borgheim, NO. Assignee: PGS Geophysical AS, Lysaker, NO. A paravane for a seismic acquisition system includes a float,
a frame suspended from the float, deflectors affixed to the frame, and means for coupling a tow rope to a lead-in functionally extending between a forward end and an aft end of the frame. The paravane includes means for selectively changing an effective position along the lead-in of the means for coupling the tow cable. Figure 13 shows a typical marine seismic survey system that can include paravanes and paravane connecting bridles according to the various aspects of the present invention. The acquisition system includes a seismic vessel 10 that moves along the surface of a body of water 11 such as a lake or the ocean. The seismic vessel 10 may include certain electronic equipment, shown at 12 and for convenience collectively called a “recording system.” The recording system 12 typically includes a recording unit for making a record with respect to time of signals generated by various seismic sensors in the acquisition system. Figure 14: One embodiment of a paravane.
Pat. 7,881,153
Figure 13: Plan view of a typical marine seismic survey system that can include steerable paravanes.
The recording system 12 also typically includes navigation equipment to determine at any time the position of the vessel 10 and each of a plurality of seismic sensors 22 disposed at spaced apart locations on streamers 20 towed by the vessel 10. The foregoing elements of the recording system 12 are familiar to those skilled in the art and are not shown in the figures for clarity of the illustration. In the present invention, the recording unit 12 may also include devices for controlling operation of a paravane steering device. In the seismic data acquisition system shown in figure 13, there are six seismic sensor streamers 20 towed by the seismic vessel 10. The number of seismic sensor streamers may be different in any particular implementation of an acquisition system according to the various aspects of the invention, therefore, the number of streamers shown in figure 13 is not intended to limit the scope of the invention. As explained in the Background section herein, in seismic acquisition systems such as shown in figure 13 that include a plurality of laterally spaced apart streamers, the streamers 20 are coupled to towing equipment that maintains the streamers 20 at selected lateral positions with respect to each other and with respect to the seismic vessel 10. As shown in figure 13, the towing equipment can include two paravane tow ropes 16 each coupled to the vessel 10 at one end through a winch 19 or similar spooling device that
enables changing the deployed length of each paravane tow rope 16. The other end of each paravane tow rope 16 is functionally coupled to a paravane 14, typically through a set of cables called a “bridle”. The paravanes 14 are each configured to provide a lateral component of motion to the various towing components deployed in the water 11 when the paravanes 14 are towed in the water 11, and in various aspects of the present invention such lateral component of motion can be adjustable or controllable. Lateral in the present description means essentially transverse to the direction of motion of the vessel 10. The lateral motion component of each paravane 14 is opposed to that of the other paravane 14, and is generally in a direction outward from the centerline of the vessel 10. The combined lateral motion of the paravanes 14 separates the paravanes 14 from each other until they put one or more spreader ropes or cables 24, functionally coupled end to end between the paravanes 14, into tension. As used in the present description, the term “cable” generally means a device that includes one or more electrical and/or optical conductors therein for carrying electrical power and/or signals from the vessel 10 to and/or from various components of the seismic acquisition system. A cable as used in the present context may also include various forms of armor or other device to carry axial loading along the cable, and thus may be a load bearing part of the acquisition system. The term “rope” is generally used in the present description to refer to a flexible, axial load carrying member that does not include any form of electrical and/or optical conductor, and as such is used essentially only to carry axial loading. Such rope may be made from fiber, steel or other high strength continued on next page

Load control power transmission Pat. 7,900,894 U.S. class 254/348 Int. class B66D 1/14 Inventor: Bruce A. Copp, Burnsville, MN., Gary L. Veikley, Inver Grove Heights, MN., Ryan M. Stanoch, Oakdale, MN. Assignee: Hydralift AmClyde, Inc., St. Paul, MN. The present invention is a transmission used with a winch drum. The transmission includes a drive shaft, an output shaft, a hydraulic or pneumatic system, a cooling system, a gear coaxially mounted on the output shaft, and an electric motor for powering the gear. The drive shaft is adapted to drive the winch drum and includes a clutch disc extending generally radially outwards from the drive shaft. The clutch disc has a face. The output shaft coaxially surrounds at least a portion of the drive shaft and includes a friction surface extending generally radially inward. The friction surface has a face opposing the face of the clutch disc. The hydraulic or pneumatic system is adapted to bring the faces into contact, and the cooling system is adapted to remove heat from the friction surface via a fluid coolant. Towing/anchor-handling marine vessels are equipped with winches. When paying out or hauling in wire rope or holding a load stationary, the winches and their wire rope are often subjected to load surges and peaks because of wave action encountered by the vessel. These load surges and peaks can cause the wire rope to fail. The length of wire rope to be paid out from a winch can be significant. Thus, payout of wire rope at normal winch operating speeds can require substantial amounts of time. Figures 16 and 17 are, respectively, a starboard elevation and a plan view of a marine vessel 1 equipped with the anchor-handling/towing winch system 2 of the subject invention. As illustrated in one embodiment, the winch system 2 is mounted on the deck 3 of the marine vessel 1 with the winch system’s wire ropes 4 feeding towards the stem 5 of the vessel from the winch system 2. In other embodiments, the winch system 2 is mounted on the deck 3 of a marine vessel 1 so the wire ropes 4 feed towards other parts of the vessel 1, such as the bow 6. Figure 18 is an isometric view of the anchor-handling/towing winch system 2 as viewed from an elevated, port/stern position. As shown in figure 18, the winch system 2 includes a port tow drum 10, a starboard tow drum 11, an anchor-handling drum 15, and a load control power transmission 20. The

drums 10, 11, 15 carry wire rope 4. The load control power transmission 20 drives and/or brakes the drums 10, 11, 15 during the winch system’s various in-hauling and payout operations. As shown in figure 18 and explained in the following discussion of figures 19 and 20, the load control power transmission 20 employs a load limiting clutch 65a, 65b directly on each drive shaft 70a, 70b to eliminate the effects of motor and power train inertia. Because of each clutch’s location, the speed of its associated motor 45a, 45b, which is operably coupled to a shaft 70a, 70b

and associated drum or drums 10, 11, 15, does not have to remain directly proportional to the drum speed during payout. Thus, the load control power transmission 20 allows full control of the wire rope 4 for normal in-hauling and payout operations, while allowing rapid payout of wire rope 4 during surge or peak load situations, thereby reducing the risk of broken ropes. For a more detailed discussion of the load control power transmission 20, reference is now made to figure 19, which is an isometric view of the transmission 20 illustrated in figure 18, as viewed from the same elevated, port/stern position. As shown in figure 19, the transmission 20 includes a starboard power assembly 25, a starboard drive shaft assembly 30, a port power assembly 35, and a port drive shaft assembly 40. The starboard power assembly 25 is operably coupled to the starboard drive shaft assembly 30. Similarly, the port power assembly 35 is operably coupled to the port drive shaft assembly 40. As shown in figure 19, the power assemblies 25, 35 each include an electric motor 45a, 45b, a power shaft 50a, 50b, a continued on next page Wire Rope News & Sling Technology April 2011

brake 55a, 55b, a primary gear reducer 60a, 60b, and a fluid cooled multi-disc clutch 65a, 65b. Each electric motor 45a, 45b drives a power shaft 50a, 50b that runs a primary gear reducer 60a, 60b coupled to a fluid cooled clutch 65a, 65b. Each fluid cooled clutch 65a, 65b, when engaged, transfers the power of its respective electric motor 45a, 45b to its respective drive shaft assembly 30, 40. The less a clutch 65a, 65b is engaged, the greater the amount of slip between its power assembly 25, 35 and the respective drive shaft assembly 30, 40. The drive shaft assemblies 30, 40 each include a drive shaft 70a, 70b supported by drive shaft support bearings 75. The port drive shaft 70a has a port tow drum drive pinion 80a and the starboard drive shaft has a starboard tow drum drive pinion 80b. In one embodiment, as shown in figure 19, the starboard drive shaft 70b has an anchor-handling drum drive pinion 80c. In another embodiment, the anchor-handling drum drive pinion 80c is located on the port drive shaft 70a. Each pinion 80a, 80b, 80c is paired with a jaw clutch 85a, 85b, 85c. As can be understood from figures 18 and 19, the port tow drum drive pinion 80a interfaces with, and drives, a drive gear on the port tow drum 10. When the port tow drum 10 is to be driven, the jaw clutch 85a engages the pinion 80a, causing the pinion 80a to rotate with the port drive shaft 70a, thereby driving the port tow drum 10. When the clutch 85a is disengaged from the pinion 80a, the port tow drum 10 is not driven because the port drive shaft 70a is free to rotate within the pinion 80a. As shown in figure 19, a center jaw clutch 90 resides between the opposed ends of the drive shafts 70a, 70b. When the center jaw clutch 90 is disengaged, the drive shafts 70a, 70b are independent of each other and free to rotate at different speeds and different directions, each drive shaft 70a, 70b being driven by its own power assembly 25, 35. Thus, for example, when the center clutch 90 is disengaged, the port power assembly 35 may drive the port drive shaft 70a in one direction to cause the port tow drum 10 to payout its wire rope 4, while the starboard power assembly 25 may drive the starboard drive shaft 70b in the opposite direction to cause the anchor-handling drum or the starboard tow drum to haul-in its corresponding wire rope 4. As indicated in figure 19 and more fully shown in figure 20, which is a sectional elevation along section line AA of figure 19 and through the port clutch 65a, port gear reducer 60a, and outer end of the port drive shaft 70a, the outer end portion of each drive shaft 70a, 70b passes through the primary gear reducer 60a, 60b and terminates within the clutch 65a, 65b. As shown in figure 20, the primary gear reducer 60a includes a housing 100, a drive gear 105, a reducer output shaft 72

110, support bearings 115 for supporting the reducer output shaft 110 off of the housing 100, and support bearings 120 for supporting the reducer output shaft 110 off of the drive shaft 70a. As indicated in figure 20, the drive shaft 70a is supported by the support bearings 75 and is coaxially, rotatably displaceable within the reducer output shaft 110 when the clutch 65a is not fully engaged. The reducer output shaft 110 is rotatably displaceable within the housing 100 and supported by the support bearings 115, 120. The drive gear 105 is coaxially mounted on the reducer output shaft 110 and transmits the power from the electric motor 45a, via the power shaft 50a, to the reducer output shaft 110. The power is then transmitted from the reducer input shaft 110 to the drive shaft 70a to a greater or lesser degree, depending on the degree of clutch engagement. Method and apparatus for manufacture of a non-helical subsea umbilical Pat. 7,903,914 U.S. class 385/100 Int. class G02B 6/44 Inventor: Ronald E. Smith, Seabrook, TX. Assignee: Deep Down, Inc., Channelview, TX This patent presents a method and apparatus to produce a non-helically wound subsea umbilical. The apparatus to produce a non-helically wound umbilical may be portable to facilitate manufacturing of subsea umbilicals in remote locations. This apparatus is smaller and more economical to build and operate than conventional cabling machines that currently are used by many manufactures to produce helically wound subsea umbilicals. The machine shown in figures 21 and 22 may produce any type of umbilical. In figures 21 and 22 it is configured to produce a “10 around 4” type umbilical, as better seen in section view in figure 23. The “4” refers to the four inner conduits and the “10” refers to the ten outer conduits. This machine may be reconfigured to produce other types of umbilicals such as those shown in figures 24 and 25, and other types of umbilicals, not shown. For different configurations, the feed section 172 is modified from that shown in figure 21 as will be appreciated by those skilled in the art. For example, to make the 12 around 6 umbilical of figure 24, twelve outer conduit reels are positioned behind 6 inner conduit reels in an alternative design of the feed section. For example, to make the 14 around 8 umbilical of figure 25, fourteen outer conduit reels are positioned behind eight inner conduit reels in an alternative design of the feed section. Referring back to the feed section 172 shown in figure 21, a first inner conduit 10 is wound on a first reel 12 which is supported on a first reel stand 14, not shown. A second inner conduit 16 is wound on a second reel 18 which is supported

22 or to the reel 376 on vessel 372. Figure 23 is a section view of a “10 around 4” umbilical 158 produced by the machine 8 of figures 21 and 22. The umbilical 158 is non-helically wound, unlike the prior art. The term “conduit” as used herein includes: a) tubes for fluids including hydraulic fluids and/or chemicals; b) electrical power cables; c) fiber optic cables; d) wire rope; e) fillers; f) reinforcements and/or combinations thereof. The umbilical 158 is called 10 around 4 because there are four inner conduits, 10, 16, 22 and 28 surrounded by ten outer conduits, 60, 66, 72, 78, 84, 90, 98, 104, 110 and 116. In this view, conduit 116 is a wire rope 117. In this view, the fourth inner conduit 28 is a fiber optic cable 29 and second inner conduit 16 is an electric power cable 17. To add weight to the umbilical 158 every other outer conduit could be a wire rope or some combination of wire ropes and conduits. Weight may be added to reduce vortex induced vibration which is sometimes referred to in the industry as “strumming.” Figure 23: Section view of a 10 around 4 umbilical produced by the machine of figures 21 and 22.

A fourth inner conduit 28 is wound on a fourth reel 30 which is supported on a fourth reel stand 32, not shown. As shown in figure 21 by the bracket A, the first back tensioner 34, the second back tensioner 122, the first entry guide 36, the first sizing die 38, the first taping head assembly 40, the second entry guide 48, the second sizing die 126 and the second taping head assembly 128 may be mounted on a skid, not shown to facilitate portability. A second skid and a third skid are indicated by the brackets B and C in the following figure. Figure 22 is a schematic view of a rear portion 148 of the machine to produce non-helical umbilicals 164.

full of the taped bundle of outer conduits 129 which surrounds the taped bundle of inner conduits 146. These bundles of conduits pass through a crosshead extruder 150, well known to those skilled in the art. The crosshead extruder applies a jacket 51, better seen in figure 23, to the taped bundle of outer conduits 129. The jacket may be plastic, elastomer, rubber and/or combination thereof. Reinforcements, not shown, may be used in the application of the jacket for strength. The non-helical umbilical 164 then passes through a cooling tunnel 152 at a temperature and rate suitable for cooling the jacket. A caterpillar draw machine 154, well known to those skilled in the art, includes an upper tread assembly 156 and a lower tread assembly 158. The upper tread moves counterclockwise in the direction of the arrow and the lower tread moves clockwise in the direction of the arrow to pull the umbilical through the cooling tunnel. The completed umbilical 164 may be fed to a carousel, not shown, the reel Y in figure
Take-up reel for metallic filament Pat. 7,891,599 U.S. class 242/580 Int. class B65H 75/28 Inventor: Kazuhiro Kishimoto, Hyogo, JP., Akio Kataoka, Hyogo, JP. Assignee: Tokusen Kogyo Co., Ltd., Hyogo, JP. The present invention relates to a reel for taking up a metallic filament such as steel wire, steel cord, wire rope, electrical wire, and the like, and particularly relates to a reel structure for securing an end part of the metallic filament that has been wound up onto the reel. To secure the end part of a metallic filament taken up onto a reel, the take-up reel for metallic filament has a recessed portion provided in the inside surface of a flange, the recessed portion extending in the radial direction to the flange outer edge; and a connecting portion that straddles the recessed portion. A tabular end retaining member having elasticity is fitted into the recessed portion. The base end portion of the end retaining member is passed under the connecting portion and butted up against the end surface of the recessed portion on the winding drum side, and a space is provided between the tip end portion of the end retaining member and the flange outer edge to allow the end part of the metallic filament to be caught therein. The end retaining member is anchored to the connecting portion through spot welding, using a welding portion set in the vicinity of the base end portion. In a take-up reel for metallic filament provided with a flange on both sides of the winding drum, the following can be given as a general example of a conventional structure for securing the end part of the metallic filament when the metallic filament is fully wound up on the reel. A small hole is provided in the outer circumference of the flange, and an end retaining member composed of steel wire, a plate spring, or the like is provided on the surface of the outer circumference of the flange in the vicinity of the small hole. The end part of the metallic filament is led through the small hole and is then sandwiched between the end retaining member and the outer surface of the flange. However, in such a case, the operation for passing the end part of the metallic filament through the small hole is troublesome, as is the operation for removing the end part when releasing the metallic filament. In particular, with steel cord used in tires, steel cord is typically unwound from more than 500 reels during the rubber coating process (calendaring process), one of the intermediate processes in tire manufacturing; it takes an inordinate amount of time to release the end parts of the steel cord from the end retaining members of such a large number of reels. continued on next page Wire Rope News & Sling Technology April 2011

Figure 24: Schematic diagram illustrating a configuration of a reel for metallic filament.
Furthermore, if the metallic filament is a stranded wire such as steel cord or wire rope, there is a problem in that the end part frays and becomes difficult to pass through the small hole; for this reason, it is necessary to wind the end part in tape or weld the strands to one another through fusion in advance, which has been a very complicated process. In order to solve the abovementioned problems, there has been proposed a reel onto which is attached an end retaining member capable of protruding from and receding into an access hole formed in a flange, the end retaining member having a catcher for retaining the end of the metallic filament at the tip. Figure 26 is a schematic diagram illustrating a configuration of a reel for metallic filament, whereas figure 27 is an enlarged cross-sectional view of an end retaining member of the reel for metallic filament. The take-up reel for metallic filament according to this embodiment has, as shown in figure 26, flanges 2 and 2 provided on both ends of a winding drum 1. A recessed portion 3 is provided in at least one area in the inside surface of the flanges 2 and 2, and extends in the radial direction to the flange outer edge 2a; and a connecting por-

tion 4 is provided partway along the recessed portion 3, straddling the recessed portion 3 in the circumferential direction, thereby connecting the inside surface of the flange on both sides of the recessed portion 3, the connecting portion 4 being flush with the inside surface of the flange on both sides of the recessed portion 3. A tabular end retaining member 5, which is a metallic plate having elasticity, is fitted into the recessed portion 3; the tip end portion 5a of the end retaining member 5 is slightly bent outwardly along the flange outer edge 2a, and the corners of the tip end portion 5a are rounded off through beveling. The base end portion 5b of the end retaining member 5 is passed under the connecting portion 4 and butted up against the end surface 3a of the recessed portion 3 on the winding drum side, and a space A is provided between the tip end portion 5a of the end retaining member 5 and the flange outer edge 2a to allow the end part of the metallic filament W to be caught therein. In such a state, the end retaining member 5 is anchored to the connecting portion 4 through spot welding, using a welding portion 6 set in the vicinity of the base end portion. In this example, a metallic plate is used as the tabular end retaining member 5 having elasticity; however, a material having elasticity, such as plastic or the like, may be used instead of metal. Furthermore, the end retaining member 5 may be processed as appropriate so as to take on a bumpy shape, a wave shape, or the like, so that the end part of the metallic filament W is caught thereby; the surface roughness of the end retaining member 5 may also be increased so as to increase the friction between the end retaining member 5 and the end part of the metallic filament W. A steel cord having a so-called 1x7 construction, in which seven metallic strands 0.33 mm in diameter each are twisted together, was taken up using this reel. The overall diameter of this steel cord is 0.99 mm. When the end part of this cord is introduced through the space A and is drawn in the central direction of the reel, the end part is securely sandwiched between the end retaining member 5 and the flange 2. At this time, the end part of the metallic filament W is drawn into the space between the end retaining member 5 and the flange 2, and the end retaining member 5 is bent into a bow shape, as indicated by the dash-double-dot line in figure 27, to a degree that does not exceed the elastic region of the end retaining member 5, with the part where the connecting portion 4 and the end retaining member 5 make contact with one another being the point of support; force is exerted in the direction that presses down upon the end part of the metallic filament W. Furthermore, static friction arises between the end retaining member 5 and the end part of the metallic filament W, and between the end part of the metallic filament W and the flange 2. The end part of the metallic filament W is sandwiched due to these forces. Next, it was confirmed that the metallic filament W can be released easily simply by strongly pulling the end part of the metallic filament W in the outer radial direction, from the state mentioned above. After the metallic filament has been released, the end retaining member 5 returns toward the flange 2 due to its elasticity, and returns to the form indicated by the solid line in figure 27. If the space A between the tip end portion 5a of the end retaining member 5 and the flange outer edge 2a is too large, the tip part of the metallic filament W will be caught therein when the filament is taken up on the reel, and thus it is preferable for the size to be such that the tip end portion 5a is nearly touching the flange outer edge 2a, and the end part of the metallic filament W barely fits therein.

Lincoln Hoist announces addition of RFID to its products
Enhances safety and accident prevention programs
Lincoln Hoist, the originator of the lever ratchet winch hoist or “come-along,” is introducing improved new models that include RFID tags, serialization, and more visible markings. These benefits will be made available to customers with no change in prices. Regular inspection by a qualified person is one of the best ways to prevent accidents using this, or most any other tool used for lifting or pulling heavy loads. RFID tags help reduce the paperwork burden of performing and maintaining those inspection records, according to a company release. Lincoln Hoist’s newest improvement embeds a small 8mm RFID chip directly into the main hoist housing to facilitate the task. In addition, Lincoln Hoist has reached an agreement with Infochip Systems to provide free inspection, certification and tracking software**. This limited version (for Lincoln Hoist products only) of the widely used Infochip system is intended to offer inspection and certification report functions to smaller companies. According to Lincoln president Dave Hallen, “Large customers are requesting the RFID tags more and more. They have already discovered the benefits of using RFID software systems to keep track of fixed assets and to record inspection and certification information. Even though we aren’t charging customers for the chips, we want to be sure that smaller customers can get the benefit of RFID without the need to get into a full installation of the software. We are very pleased to be able to offer this package through Infochip Systems.” RFID technology enables customers to quickly call up specific hoist information by reading the data embedded in the chip. They can then see pre-loaded information regarding inspection points, evaluate and record the various attributes, create notes, and generate inspection reports or certificates. Enhancements planned for the future include the ability to have parts diagrams immediately available for quick call-out of correct repair part 76
numbers. According to Hallen “It’s important to understand that no other changes are being made to our tried and tested products. All of the internal workings are identical to (and interchangeable with) our older hoists. If you liked the tools that we’ve built for the past 60 plus years, you will like these. You just get new added functionality at no cost.”
**While the software license is free, InfoChip software is web based (no software to install) and so does require a modest fee for setting up each new customer.

The DCS-Pro electric chain hoist line from Demag Cranes & Components is packed with standard features that allow operators to handle and precisely position critically sensitive loads with ease, according to a company release. These include an infinitely-variable speed control with soft starting speeds as low as 3.15 inches/minute; a 1:200 control ratio that produces gentle positioning in addition to high speed travel; automatic switchover to low speed prior to reaching the upper/lower stop; acceleration and braking ramps to prevent load sway; and up to 90% higher nominal speed for partial load or no-load operations. Designed with safety, convenience and low maintenance in mind, the entire family of DCS-Pro chain hoists includes as standard 24V control voltage and operating limit switches for improved safety and reliability, a brakecoupling system which ensures that loads are held securely in all operating situations, and a speed monitored slipping clutch for effective cut-off on overload allow safe operation. The DCS also comes standard with “plug & lift” connections that make the hoist simple to install, while the gearbox, brake and slipping clutch are maintenance-free for up to 10 years, while the modular chain drive can be quickly and easily replaced without having to remove the motor or gear parts.

Mighty-Eco-Ergo mobile crane
“New” reversible boom crane, EcoConscious, for indoor use Air Technical Industries announces the launch of the NEW RBC50000SPBW Self-Propelled Walk-Behind Mobile Crane. The first of its kind, it is Eco-Conscious and energy-efficient in lifting-transporting technologies with the mighty muscle power of 50,000 lbs capacity, according to a company release. Designed for indoor use where heavy components need to be lifted, transported, positioned, installed and assembled to help make your job easier, along with satisfying the green initiative. Keep the facility cleaner, quieter, and safer, with environmental overtone; no fumes, no gas, no smell, no smoke, just mighty power and flexibility. The crane can lift up to 50,000 lbs and up to 240 inches high. It is selfpropelled with infinitely variable speed controls. It features power steering with sharp turning to each side making it very easy to maneuver. The powered telescopic boom will reach beyond, over and under, or into hard to reach places. These features make it ideal for lifting components such as large castings, motors high up on to a pedestal, gen-packs, compressors, boilers, transformers and aircraft engines. It can be used for many applications such as assembly work, loading trucks, container handling, etc. The unit is user friendly. It is very continued on page 78
continued from page 76 simple and easy to operate with dual controls for greater flexibility. All controls are push button operated and built into the steering handle. It has another control on a remote pendant so that operators can align the load precisely where needed. The unit featured is equipped with an optional Gooseneck Boom to reach into tight spots between the ceiling and highest positioned item for installation and removal. This is ideal for low-headroom applications.
The crane travels on ten (10) polyurethane wheels to reduce and spread floor loading and to protect the floor. All wheels are equipped with precision machine roller bearings for smooth, quiet and easy mobility. The propulsion is DC battery powered 48V. Solid state control provides smooth acceleration and deceleration. An automatic braking system is built into drive wheel motors, and is applied when the controls are released. The travel speed is from 0-3 MPH. The boom lifting, telescopic boom action, and powered steering are hydraulically operated. The hydraulic cylinder shafts are made from high carbon tough steel, ground, polished and chrome-plated, which protects from corrosion and provides smooth, efficient operation. The Hydraulic system is equipped with safety relief valves to protect the system and to prevent over loading. The RBC-series of cranes are available in a variety of capacities and sizes from 1000, 2000, 3000, 4000, 6000, 10,000, 15,000, 20,000, and 50,000-pound capacities. Smaller models start at only 34” wide, narrow enough to fit through a doorway. Built to make the job ERGONOMICALLY easier and safer in any operation, the RBC will help increase efficiency, productivity, save time, and energy. Made in AMERICA with heavy78
duty steel welded construction for many years of tough industrial use.
Wiley X® Airborne™ model flys high above the rest with sleek styling and safety features ideal for industrial workers
Bring on the dirt. Bring on the glare. Bring on the wind. Bring it all on because you’ll be ready with the Wiley X® Airborne™ safety-rated sunglasses built tough enough for work, but cool enough for play. From machining to assembly to work on an oil rig, these RX-ready glasses have been designed specifically for the special safety needs of the industrial workplace. A member of the Wiley X feature-packed Climate Control™ Series, the Airborne glasses were created by the same designers that developed the company’s U.S. Military grade glasses. According to a company release, this means precision, safety and ultra functionality were principal factors when crafting these performance safety glasses. The design of the Wiley X Airborne begins with meticulously crafted comfort and fit. The Airborne includes Wiley X’s patented removable Facial Cavity™ seal made of soft, comfortable foam, which easily snaps in and out of the frame, virtually presenting a pair of glasses and goggles in one. The seal works to keep wind, dust and debris out of the wearers’ eyes and features the company’s special Top Down™ Ventilation to prevent fogging while hard at work. The Wiley X Airborne glasses are constructed from some of the world’s most indestructible materials. The ANSI Z87.1-2003 safety-certified frames are fashioned from tough Triloid Nylon, so they can stand up to even the most challenging work environments. The Airborne lenses play two vital roles: providing for paramount clarity as well as ultimate safety. Far exceeding ANSI Z87.1-2003 safety and optical standards, each lens is crafted from shatterproof Selenite™ Polycarbonate and is finished with a scratch-resilient T-Shell™ hardcoat to protect against scratches and nicks. The Airborne is available in various lens tints including smoke grey, polarized smoke green, LA™ Light Adjusting bronze and clear. While safety and clarity came first, perhaps the best thing about the Wiley X Airborne glasses is that designers have taken all this advanced technology and transformed it into great-looking glasses that workers will want to wear. With frames available in gloss black,
Wire Rope News & Sling Technology April 2011
matte black and metallic black, the Airborne is a truly striking pair of glasses. Fitting medium to large head sizes the Airborne can also be fitted with prescription safety lenses that meet ANSI Z87.1-2003 safety requirements. When it comes to protection, no one beats Wiley X, the only premium performance sunglass manufacturer whose entire line meets ANSI Z87.12003 high velocity and high mass impact standards. To learn more about the Airborne glasses, the Safety Series from Wiley X — or the company’s full line of high performance eyewear for work and play — visit Wiley X Eyewear at 7800 Patterson Pass Rd. Livermore, CA 94550 • Telephone: (800) 776-7842 • Or visit online at www. wileyx.com. For updates on Wiley X pro athletes and events, find us on Facebook at www.facebook.com/wileyxeyewear.
