Wire Rope A Major Part of New BSA Center in West Virginia By Peter Hildebrandt

The new permanent Boy Scouts of America Jamboree Center at the New River Gorge is now officially open and will in turn grow for a few weeks each fourth summer to become one of the largest “cities” in the state as visitors flock to the half billion dollar development. Wire rope zip lines now make the experience unforgettable for scouts lucky enough to attend. Those involved with all aspects of construction will no doubt rest easier now that all was completed by opening day in July, 2013.

onsai Design, Grand Junction, Colorado is the main contractor involved with the wire rope construction on the project. They are primarily involved with the design and construction of aerial systems, whether tree-based, canopy tours, challenge courses, towerbased big zips, aerial adventure parks as well as climbing towers. Though Bonsai Design’s systems are principally in trees, the industry has been expanding tremendously

lately and larger corporations are even starting to take notice. They’ve had to expand their services to include engineered systems for the big towers in addition to working with more ski resorts lately or more specifically those resorts without adequate trees and forest coverage, yet still interested in the construction of a zip line onsite. “The BSA Jamboree Center is out in the middle of a 10,000 acre forest where we are acting as part of a design

and consultant team. Two and a half years ago that went onsite and provided some preliminary design services studying where they could put down different villages of installation,” explains Thaddeus Shrader, Bonsai Design, Inc. Chief Executive Officer. “The Boy Scouts wanted to find the best in each field and bring us all in. We were part of a team composed of our company, Bonsai Design, Gravity Logcontinued on page 10

continued from page 8 ic, an excellent park-building company out of British Columbia and El Dorado Walls, a Boulder, Colorado-based company. Spohn Ranch, the BMX bike ramp experts was involved too; they do cityscape bike park installations throughout the country. We were proud to be part of this overall team of adventurous and studious providers.” Bonsai Design is the zip line company onsite, informing others on all the different things they could do with zip lines and challenge courses. Since work started two years ago, Bonsai Design has been hard at work installing all of this equipment and getting it ready for the Jamboree in July, 2013. They have been onsite actually longer than 24 months at this point and currently have more than 5 miles total of zip line, according to Shrader. Canopy tours require trees. Specifically these feature tree-based zip lines and wire rope bridges. Sky bridges – basically suspension bridges - are tensioned between trees, spanning up to 200 feet in length across huge gorges. Hikes are part of this system too. Tower-based big zips will feature a steelreinforced infrastructure on each end of the zip line with huge launch and landing decks. Bonsai Design has installed five at 1200 feet in length, five at 1500 feet in length and then five at 10

3100 feet in length; on these riders can reach speeds of up to 60 and 65 mph. The tower structures will use three quarter inch swaged cable. “This is a nice product that we found through Delta Rigging,” adds Shrader. “Some of the wire rope we first studied was from Israel and Germany, 37 by 19 lays, rotation-resistant and really dense cable but very expensive at six or seven dollars per foot. The product we ended up with is made in the United States. We traditionally try to buy American cable and then have Korean cable as a backup.” Bonsai Design has found that those two countries have the best wire rope product for longevity. Lately though, the US product has been falling off, according to Shrader. “The galvanization on wire rope within the last five years has been outsourced to Mexico and the quality control has not been where it used to be. The Korean product though is holding up just as well.” For the Canopy tours they used a three eighths inch coated cable with nylon jacketing out to one half an inch. Bonsai Design tries to have a minimal maintenance and wear program as part of what they deliver to their clients. Their covenant is to have no steel on steel; nobody in the challenge course industry does that. Either their cables are coated with nylon and users can run a steel sheath

Wire Rope News & Sling Technology August 2013

on them for their zip line trolleys or for the big zips it is not possible to waste that much space just with coating and the hanging weight gets to great. The working load limit on the super long lifts in turn goes up too high for the strength ratio. For those cases they use a galvanized cable or a form-fit lock joint cable. An injection-molded coating is used on their shivs and the shivs that run on the cable have soft surface wear coating on them. “One way or another we make sure that the cables are going to last for a really long time,” says Shrader. “For all our nylon-coated cable, this comes straight out of the factory in Pennsylvania. We go to Loos & Company for that material, an all in-house, all USmade product manufactured for us; this is a great product for us.” For the big lifts they use a seveneighths cable swage-compacted down to three quarters of an inch so that they can run a three quarters sheathing on it. This is produced by Delta Rigging, spun into cable here in the U.S. Traditionally that only comes in a greased form with injected, impacted grease contained inside. “This does not come with galvanization. It is used in a wide variety of crane settings; but we can’t have the grease in our operations. Yet we have to have the galvanization so the cable can hang outcontinued on page 12

continued from page 10 side and last for ten years.” Surprisingly, one of the biggest challenges Bonsai Design faces now is the really soft response from needed volunteers to run the system. Internal auditing has revealed that the zip lines and canopy tours are the number one rated thing that scouts want to do, above the BMX pump tracks, the aquatics park and everything else. However the zip lines are also what requires the most time commitment from volunteers. Four to five days of high angle rescue training just to be safe to help participants out of a jam at 200 feet above the ground if they have to. Applicants must be in excellent physical shape and be able to manipulate their bodies while in a full-body harness as well as pull themselves up. The zip line runs stretch anywhere from 150 to 1500 feet long on the canopy tours and the big zips are up to 3100 feet long; there are five of those. The topography is used quite a bit with the lines being attached to trees and guy systems are created that can flex with the forest and the wind; a lot of termination techniques come into play. A line cannot simply be bolted to the tree and then left as that will damage the tree, according to Shrader. 12

The cables will in turn go out across gorges. Then riders will get the 200 foot heights above the ground. The canopy tour runs anywhere from 15 feet up to 70 feet up into the trees depending upon how big the tree is. Setting the course up is fairly comprehensive when the course is being planned out. Each one of the lines must have a specific catenary curve that’s calibrated both in its pitch and tension to achieve a safe entry speed in the deceleration zone for the participants. “That’s just the normal thing,” explains Shrader. “You must figure out how to get the course to work sequentially with the different lengths so that each line runs correctly. Then what we did was to tie all the eight canopy tours required to be in the same gorge together. They are going over and under one another, looping in and out of each other. A kid might see somebody else zipping overhead or underneath him and realize that he’s not going on that same line, but is traveling on some other course he’s not even on. This makes it really exciting for the kids.” The canopy tours have brake systems at the end of each line that they can slow the riders down with but overall riders will be able to travel as fast as

Wire Rope News & Sling Technology August 2013

the wind will allow them to travel. A closed-loop brake is used to slow riders down when they reach the end of each line; Bonsai Design came up with that design themselves. The company ordered components from and worked with a variety of different climbing equipment supply companies. Delta Rigging supplied wire rope as well as a lot of the hard goods that go into building a lot of courses, including fist links, rapid links and huge rigging sheaths. Also, all of their nylon-coating wire was produced by Loos and Company in Pomfret, Connecticut. “Delta Rigging really jumped through some hoops for us to find the right wire rope for us and that it was available,” adds Shrader. “The guys at Delta Rigging worked very hard to keep our business with this initial order. We had a very specific wire rope that we wanted to; the Germans and Israelis didn’t have any available. I was extremely impressed with those guys. At the jamboree’s opening this summer there were some 32,000 scouts and leaders with an additional 8,000 staff for an approximate total of 40,000 participants. Although the AT&T summit continued on page 14

continued from page 12 stadium has an expected maximum capacity of 70,000, the stadium had approximately 41,000 in attendance at the stadium for the Saturday night show. “Perhaps the biggest overall challenge for us on this site has been interacting with all the different big, heavy infrastructure companies involved. They are preparing and moving millions of yards of dirt to construct an amphitheater for 70,000 people and creating a small city that will go from up to 70,000 participants and visitors for ten days back to zero again. It’s an exercise in instant-urbanism, bringing all the necessities together. “This was the biggest construction site in the United States while it was being worked on. Our workers are used to going into the forest and disappearing all day, seeing no one except for us. Trinity Works was the main contractor on the site.” The philosophy on this job is to plan and think of the future, the future 100 years out, according to Shrader. The big, heavy infrastructure is being put in now and then for the next three or four years they will continue to construct buildings to eventually make this the mecca of the Boy Scouts. The nylon jacketing on the wire rope allows for a smoother ride and experience in addition to protecting the cable itself, according to Robert Davis, Loos and Company sales and marketing manager. “I have always understood that keeping the ride as quiet as possible always makes for a more enjoyable experience. Running on bare metal will definitely be a noisier situation. “Supplying the material for this project wasn’t difficult for us to do; it was well within the realm of our capabilities as a manufacturer. What was most rewarding for us was to be able to work with our expertise in the cable business and match up with the requirements that Bonsai Design had for durability and user experience and then matching the correct product with their application. Loos and Company is very good at working in these specific applications and working within our competencies and capabilities. We fit well with niche situations.” It helps to be able to provide them with a consistent and quality product that can be used without reinventing the wheel each time. Davis finds Bonsai Design truly a niche application as projects continue to arise from the company from California to Maine. “We’re shipping to adventure parks and courses that Bonsai Design is doing all over the country,” says Davis. “We are generally shipping them cable all the time. 14

For a project such as this it tends to take a couple of months to get everything ready before we ship to them. “I think it’s wonderful that the industry is such that geographically dispersed companies can work together on a project like this. To support the Boy Scouts in West Virginia a Colorado company contacted a wire rope company in Connecticut; it’s just great to get our product down there and to be a part of this. It’s never the biggest or the most consuming projects that give you the most pride, it’s these smaller ones where we can find the right mix of cable know how and performance and get that out there to them. In addition to this we know the kids are going to be safe, Bonsai is a great company to work with; we make a great product here with Loos and Company.” Delta Rigging is virtually the only rigging house between Denver and Salt Lake City an area that is also seeing a lot of growth in the oil, gas and energy industry. They take care of several coal mine operations as well as gas, oil drilling and crane services. “This job was a lot of legwork matching safety factors of this job were different versus prior jobs; the strength factor had to go up on the rope,” explains Justin Tate, Delta Rigging inside sales rep. “At one point their engineering was pushing to use a non-spin rotationresistant rope because of the strength. But it was so expensive and their budget wasn’t close to that. We had to find some middle ground. “Once you start looking at non-rotational, it’s very strong but very costly. Fifty thousand feet of rope all of a sudden becomes very expensive very fast. We deal direct with mills quite a bit - avoiding the middle man – and this gives us better buying power as well as saving money.” Delta Rigging was able push the mill to meet the due date that was required for the West Virginia project, according to Tate and to get a great price as well. “But every time we thought we had it figured out for them there seemed to be changes. The biggest challenge was meeting the deadline. For about half of the rope we went directly to the mill and for the other half we were able to pull from local suppliers. Once we got the strengths right that engineering was requiring – including changes – at that point we had to go to stronger rope. We had samples flown in to get them to try for a speed run.” As soon as it was narrowed down they could concentrate on their May first deadline, having all the rope sitting in

Wire Rope News & Sling Technology August 2013

West Virginia. On this project they had barely 90 days and they also had to push the mill to get it even sooner than that to where they could have the wire rope delivered on site to the project within in 90 days. The mill they worked with finally came through with no problem. “It was literally six weeks of back and forth, back and forth as well as being nothing more than finding the best bang for the buck. We had to make sure that it was realistic; every time we pushed the envelope a little bit I had to make some phone calls be certain we could do it. I had to know we could do it. Sure we can say we can do it, but we don’t want to tell you that, unless we can actually do that. That was the biggest challenge, jumping through the hoops to make sure it would all work.” Timing was critical in getting the right price. It is common for something to be needed immediately in the energy industry, according to Tate. “But we’d never dealt with a zip line manufacturer before – at least out of this office – so knowing what they were trying to do and who is very transparent was a great experience. This was something new that we’d never done out of here. We’re looking forward to doing a lot with Bonsai Design because they are a great company, easy to work with and talk to. “They gave us a shot at this; that’s all we wanted. Being able to meet their deadline was huge. The best quality for the best price, within the deadline all came together somehow. We had, at one point 30,000 feet of their shipment – here waiting to be delivered.” The remaining 17,500 feet came in as expected the next week. Delta Rigging has dealt with Bonsai Design on a lot of other tooling as well, opening a door for them in other areas. Work started in the middle of December with working going forward earnestly in January. End fittings and pull testing still needs to be done on the second half of the order. This will happen once the rest of the order comes in from the mill. “We are a full service rigging shop,” adds Tate. “We deal with all major manufacturers and build custom rigging in here every day; there’s not much we can’t do.” For scouts zipping over and underneath each other on a spider’s web of wire rope intermingled among the West Virginia forest, during the unforgettable summer of 2013 there was little time to wonder about all the construction details. But that doesn’t mean they didn’t appreciate all the hard work of getting things all set up and ready to go before July of 2013. WRN

Wirerope Works, Inc., Aids in Success of Nik Wallenda’s Harrowing Walk Over Gorge By Kay Shirk

Earlier this summer when Nik Wallenda crossed over the Little Colorado River Gorge near the Grand Canyon on a tightrope—without a safety net—he trusted the expertise of Wirerope Works, Inc., manufacturer of Bethlehem Wire Rope in Williamsport, PA, to help him accomplish his daredevil feat.

allenda’s successful walk would never have been possible without the efforts of Wirerope Works’ engineering team who worked closely with Wallenda’s own group to design a rope that would meet his exact specifications. In fact, the 2,200-foot cord manufactured by Wirerope Works was the same one that Wallenda used to cross Niagara Falls in June 2012. Just two inches thick, the “special order” rope took about 16 to 18 weeks to produce. It weighed

eight tons—heavy enough so it would not sway too much in a breeze—and was composed of six strands, with 49 wires each and a steel center with 49 wires. It could have held up to 200 tons. Kim Konyar, product engineer at Wirerope’s plant, said that Wallenda had approached three companies that make wire ropes before he settled on Wirerope’s product. “He actually toured the facility,” Konyar said, and Wallenda chose to have his tightrope made by Wirerope Works

because he liked the plant’s manufacturing process and the people he dealt with there. “He wasn’t sure what he wanted at the time.” Konyar said. “We made the decision on what type of wire rope Nik required and what the production and operating parameters needed to be. From that information, I was able to design the ropes and issue the specific requirements for production and testing. We did a break test here to prove that it had the strength it needed.” He

Wirerope Works, Inc., manufactured the rope used by Nik Wallenda for his historic walks over Niagara Falls and the Little Colorado River Gorge, Grand Canyon.

Wire Rope News & Sling Technology August 2013

Nik Wallenda used Wirerope Works’ rope in June 2012 to make his death-defying walk over Niagara Falls at night in a near-blinding mist.

added that those who came in contact with Wallenda found him to be an interesting person. The 34-year-old Wallenda of Sarasota, FL, comes from a family known for their death-defying feats. He is a seventh-generation high-wire artist—part of the famous “Flying Wallendas” circus family. For crossing 1,500 feet above the Little Colorado River Gorge, part of Arizona’s Grand Canyon National Park, Wallenda did not wear a harness. The event on June 23 was broadcast live on the Discovery Channel and watched by millions. Wallenda said after the walk that the winds were at times “unpredictable”; dust blew into his eyes, making it especially challenging for him to stay focused. He wore a microphone and two cameras; his leather shoes had elk-skin soles to help him keep a grip on the steel cable, and he could be heard praying quietly as he moved slowly over the gorge. The walk took more than 22 minutes, and twice he had to pause

and crouch as the winds whipped around him and the rope swayed. “I sat on the edge of my chair and held my breath the entire time he crossed the Grand Canyon,” said Norm Szamocki, Wirerope’s director of operations. Konyar added, “The strength is in the rope, integrity is in the rope.... we just sat back, white-knuckled the walk and cheered him on.” Although designing and manufacturing the wire rope for such an event was a first for Wirerope Works, their Bethlehem Wire Rope products have The wire rope manufactured by Wirerope Works, Inc., for Nik Wallenda’s high-wire feats: • took nearly 18 weeks to produce. • weighs eight tons. • measures two inches thick. • is composed of six strands, with 49 wires in each strand and a steel center with 49 wires. • is 2,200 feet long. • could hold up to 200 tons.

played a major role in many structural and offshore projects for six decades. Since beginning in 1886 as a small local wire rope mill, the company has evolved into an internationally recognized manufacturer of wire and wire rope, housed in a 46-acre facility, with more than 620,000 square feet under roof. It is now the single largest wire rope manufacturing facility in North America, manufacturing and selling wire rope, structural strand and related products. The company offers hoist, governor, compensating, standard rope, spin-resistant rope, specialized rope and plastic-infused wire ropes; spiral strand and other wire ropes; boom pendants, specialized pendants, ski ropes, cable assemblies and specialized assemblies; and rotary and plastic-infused drill, tubing, specialized tubing, sand and swab, well measuring and servicing products and mooring lines. Through its service centers it also provides customer support. Wirerope continued on next page

continued from previous page Works’ products are used in elevator, construction and industrial, logging, mining, ocean cable systems, oil field and marine, ski area and structural applications. Wirerope Works can manufacture its products in a wide range of sizes, including wire that is slightly larger than a human hair to wire rope and strand measuring more than five inches in diameter. The largest wire rope ever produced in the United States—5¾" in diameter—was made by Wirerope Works in 1995.

A Bridge Grows in Brooklyn By Peter Hildebrandt

For New York, a city existing because of the superior water bodies surrounding it, the East River challenged the linking of the city’s five boroughs as well as to the rich farmland of the largest island on the Atlantic Coast – Long Island. The idea of a bridge crossing the river was miraculous and time-saving for those residents on both sides – who were long accustomed to crowded, chilly ferry rides across the East River.

y 1860, Brooklyn was the third largest city in the United States, with only New York and Philadelphia ahead of it. But 40% of Brooklyn’s wage earners worked in Manhattan; by 1865, five ferry lines made some 1,000 trips across the East River each day. It’s hard for us today to picture the East River of those times, a rather hectic body of water. About a tenth of the inhabitants of Brooklyn boarded a Union Ferry Company vessel and crossed the East River twice each day in these cold, undependable and crowded boats. New York’s

legislature approved a construction bill for a bridge as early as 1857. During one cold winter in the 1860s the East River froze over, letting residents cross with ease; demand for a bridge became even more urgent. At the time of its completion, the Brooklyn Bridge was the largest suspension bridge in the world. Brooklyn Bridge is the first steel-wire suspension bridge in the world. Initially, Brooklyn Bridge was known as ‘New York and Brooklyn Bridge’. It was given its present name by the city government, in 1915. In 1964, Brooklyn Bridge was des-

ignated a National Historic Landmark. From 1873 to 1874 work proceeded on the iconic two neo-Gothic granite towers as well as the anchorages for the structures. They were designed to withstand strong winds and support rail lines as well; 130 years later they’re still solid and strong. John Roebling, the bridge’s designer also constructed the Cincinnati Bridge over the Ohio River. Originally from Germany, Roebling had always been fascinated with suspension bridges. After witnessing the deaths of two men due to the failure of hemp rope on the

Pennsylvania Portage Canal, he developed the technology and rope-making techniques for constructing wire rope in this country. Compared to the Brooklyn Bridge, the foundation construction on the Cincinnati Bridge structure was a snap; the bridge’s foundation is in water several feet deep at most. The East River’s bottom was sand and at that time no one had any idea how deep a foundation would have to be laid in order to support the tremendous weight of the bridge’s two huge towers. Eventually it was discovered that the foundation would have to be sunk some 40 to 80 feet deep. John’s son, Washington Roebling largely took over supervision of this Cinconstruction to free up time for his father to involve himself with other projects. Roebling’s son gained valuable knowledge and

skills from this experience. John Roebling died before the construction on the bridge had truly started from a foot crushing accident on an East River pier while he and his son Washington were inspecting the site where work was to begin. Roebling stepped to get out of the way of a boat about to land at the wharf, but instead his foot got caught on a knot on the wood and was crushed between the boat and the dock. The injury eventually resulted in his death from tetanus 17 days later. Roebling’s lifelong dislike for doctors – his belief in homeopathic cures such as hydrotherapy – most likely hastened his death; when he finally was in such agony that he was brought to a doctor the infection was already too far advanced. Roebling died in extreme pain after the tragic accident.

The building of the bridge took place with the backdrop of the 19th century politics of “Boss Tweed.” Tweed unofficially ruled government in New York with great corruption swirling around even the building of the bridge. He was arrested in the midst of its construction. “One of the biggest concerns was that, since this was a private – public partnership that the building of the bridge would be another money pit, another incredibly corrupt building project,” explains Julie Golia, Ph.D., public historian at the Brooklyn Historical Society. “In reaction to that the New York Bridge Company did everything exactly by the book, sending out proposals as per city policy, not just using Roebling’s wire. “Instead the job was opened up to anyone who wanted to apply for it.

continued from previous page the middle of work on the bridge, it was determined that the wire rope of J. Lloyd Haigh of Brooklyn was not strong enough, it was too brittle and at that point it was too late to re-wire the entire bridge. Some seven million pounds of wire went into the construction of the bridge. In the end, more wire rope had to be added to strengthen the bridge. This was one of many public relations disasters involved with the construction of the bridge; but the bridge

work succeeded, was built so strongly in the midst of this crazy political environment of the time.” Construction on the bridge started in 1869 and the bridge took 14 years to complete; the cost then was $15 million dollars which would be $320 million dollars today. A pair of watertight chambers, caissons – two, one for each of the towers and each weighing 3,000 tons – were built from wood, floated downriver to where they were needed for the foundation work. Stones were

placed atop these air-tight wooden boxes until the caissons sunk to the bottom where the foundation would eventually be. Pressurized air in turn was pumped into the chambers to allow construction of the Brooklyn Bridge’s foundation. As we may imagine, the work environment in these crude underwater containers was brutal. “Inside the caisson everything wore an unreal appearance,” described E.F. Farrington, master mechanic under John Roebling’s son Washington Roebling. “There was a confused sensation in the head, like ‘the rush of many waters’. “The pulse was at first accelerated, then sometimes fell below the normal rate. The voice sounded faint unnatural and it became a great effort to speak. What with the flaming lights, the deep shadows, the confusing noise of hammers, drills and chains, the half-naked forms flitting about, if of a poet temperament, get a realizing sense of Dante’s inferno. One thing to me was noticeable – time passed quickly in the caisson.” Washington Roebling was himself a victim of the pressure sickness also known as “the bends” which ended up crippling him for the rest of his life. Nitrogen bubbles painfully form in the body’s bloodstream as a result of the pressure difference involved. Roebling’s wife Emily, however, was instrumental in helping her husband complete his work on guiding construction of the bridge. She carried a steady stream of instructions from her husband’s sickroom to the worksite. Roebling meticulously designed the caissons. They were ingenious, if extremely dangerous due to explosions, water flooding the compartments and fire. Replacement of the caisson which was burned was expensive. When work was completed the caissons were filled with concrete. Over one hundred men suffered from what became known as “Caisson Disease”with the threat from the disease growing more critical as the the caisson went deeper into the river bottom. When work at ever greater depths tested even the bravest and most hardy of the workers and engineers, Roebling made the daring decision to halt further foundation construction while the caisson on the Brooklyn side was still 30 feet above bedrock; to this day the Brooklyn tower still rests on sand above the river bottom’s bedrock. He was an invalid after his bout of the bends. Immigrant workers ended up being paid some two dollars per day for this hazardous work. Twenty men were killed during the bridge’s construction, continued on page 24

continued from page 22 including John Roebling, the designer of the bridge and also someone who has been called the “Father of the American Wire Rope.” The bridge’s two towers were actually higher – at 276 feet – than nearly all the buildings in New York at the time. Believe it or not, after it was completed, it was the world’s longest suspension bridge. With a total length of 5,989 feet, the bridge also contained four main cables containing 3,515 miles of steel wire rope cable each and holding the platform of the bridge deck aloft were more than 1,000 suspender cables. Zinc coating of the cables was done to prevent rust – first time this procedure had been attempted on a bridge. The structure was also the first bridge to have electric lighting. By the winter of 1877 the temporary footbridge on the structure was done and workers began spinning the four main cables at the anchorages on the Brooklyn and Manhattan sides of the bridge. Those four steel cables were capable of supporting 11,200 tons each, connecting the anchorages with the two towers; cables in turn pass over saddles inside each tower. The four main cables each have a di-

ameter of 15 inches and are comprised of 19 strands incorporating a total of 5,434 steel wires. Following the spinning of the four large cables – accomplished by the fall of 1878, additional wire ropes were strung from those down to the bridge floor, with over 14,400 miles of wire used for those suspender wire ropes. Now the deck beams could be constructed and diagonal stays installed. Cables constructed in place on the bridge. Wires were laid parallel. Roebling’s sons did not make the cables for the bridge. J. Lloyd Haigh in Brooklyn made the wire rope. A breakage in some wire rope alerted construction managers to the fact that inferior wire rope had been used in the bridge. Haigh had submitted the same superior wire rope for inspections over and over. Haigh eventually went prison. Additional wire rope had to be added to strengthen the inferior rope that had been used. Roebling’s sons made the connecting wire rope attached to the main cables. Emily Roebling was the first person to cross the bridge on its roadbed, the week before its official opening in May 1883. The bridge was built in an age when materials were brought to the site by horse and wagons, with-

out mechanized tools or telephones to transmit important information. Six story buildings were skyscrapers in those days, so crossing the bridge, which its incredible height for the time was truly a marvel for residents. Emily Roebling’s remaining in the background, publicity-wise despite her being instrumental in the bridge’s construction was due at least partially to her own hand, according to Golia. “She was not a trained engineer but essentially self-trained herself to become one on site when her husband became sick. But the idea of a woman being intimately involved in such construction in the 19th Century was incredibly problematic. In the background was somewhat of a clandestine movement to try to get Washington Roebling removed as the chief engineer on the job. “Emily was therefore protecting her husband’s role by downplaying her involvement to make sure no one would be questioning whether or not he had the professional willpower, health and vitality to be able to do this project. But we cannot overstate how catastrophic it would have been for word to have gotten out that a woman was overseeing construction of what was continued on page 26

By the 1860s over a quarter of a million people lived there and by the turn of the century over one million people lived there – far too many to be serviced by a handful of ferry boats. “Lost to history is much information on the lost neighborhoods in the wake of the bridge construction. The free black community, one with little voice in the matter was displaced along with much of the industry in that area. These are stories you don’t often hear. The bridge was presented as a triumph, but the

people displaced have been largely forgotten as have those people who were either killed during construction or who later died due to their affliction with the bends which often restricted them the rest of their lives. If all of those individuals are added in, over 100 people died in the construction of the bridge over time. Directly on site some 25-35 people died.” Described as the Eighth Wonder of the world, the Great East River Bridge stood as proof of what Americans could achieve. More than a suspension bridge, connecting Brooklyn and Manhattan; it symbolizes New York. The excitement at the time it was first opened has not really gone away as the bridge’s magnificent design still inspires. It represents magnificence, change, unity, improvement, and influence. When Armstrong landed on the moon in 1969, a Long Island woman was interviewed about it; she reported in a newspaper interview that that accomplishment was alright – but it was nothing like like the day the Brooklyn Bridge opened. In 1867, John Roebling reported that he considered the bridge he designed and was about to construct be more than simply a construction project but also a work of art. We don’t typi-

Workers’ Compensation

Employers Grapple with Higher Costs By Phillip M. Perry

Employers are getting hit with higher workers’ compensation costs as the insurance industry changes its calculation for the “experience modification factor,” the critical number in the premium calculation formula. In response to escalating medical costs and a declining number of carriers, business owners are instituting programs to control the impact of workplace accidents.

mployers have long been concerned about the cost of workers’ compensation insurance. This year, though, the premium environment seems particularly harsh as the insurance industry changes the way it calculates the “experience rating modification,” or x-mod, that powerful pricing engine gear assigned to each employer. The change is expected to result in higher rates at a time when premiums are already continued on page 30

continued from page 28 rising quickly in response to escalating medical costs. As if all that weren’t enough, a growing number of carriers are leaving the market, diminishing the supply of competing policies and putting even more upward pressure on the price of this mandated benefit. It all boils down to a challenge for employers. “We are currently in an environment of rising workers’ compensation costs,” says Peter Burton,

Senior Division Executive for State Relations at the National Council on Compensation Insurance, Boca Raton, FL (ncci.com). The new math For business owners, the most immediate concern is the change in the x-mod. The portion of each claim that will flow into the experience rating formula at its full primary value will increase to $10,000 from the former level of $5,000. (See sidebar, “Calculating the New X-Mod.” on page 32)

The reason for the change, says Burton, is the growing mismatch between the cost of claims and the premiums employers pay. “The split point portion of the experience rating formula has not been updated for 20 years, a period during which the average cost of a claim has tripled,” says Burton. “So our actuaries looked at the program and saw it was out of balance.” Some industry observers recognize the connection. “The new x-mod calculation is a reflection of medical costs which have gone up exponentially in recent years,” says Daniel C. Free, President and General Counsel of Insurance Audit & Inspection, Indianapolis, IN. (insuranceaudit.com). “The NCCI is really just catching up. The new mod can be seen as a ‘true-up.’” Be that as it may, employers are sitting up and paying attention to the new math. “The x-mod changes are a big deal for employers,” says Karl Ahlrichs, benefits consultant for Indianapolis based insurance broker Gregory & Appel (gregoryappel.com). Those employers with historically safe workplaces are going to be better off under the new system. Those with more frequent, higher level claims will see their x-mods increase. “The impact will vary based on the number and size of claims the employer has had.” Carriers leaving the market A third factor contributes to premium angst: A dwindling supply of carriers serving the market. “We are seeing a growing number of cases where multiline (auto, property, umbrella, general liability) carriers are refusing to renew workers’ comp insurance for an employer whose experience is unfavorable,” says Mike Salazar, Vice President and Manager of Client Services at Gregory & Appel. The reason for carrier’s growing reluctance is clear: “In a low interest rate environment carriers cannot make up workers’ comp losses with profits from property and other insurance products.” “Employers turned down by the multiline outfits must apply to the single line workers’ comp insurance carriers,” says Salazar. While the premiums at such carriers may not be much higher, there is another problem: Insurance carriers are become more judicious in what they underwrite, due to the rising costs of the workers’ compensation system. “Single line carriers are becoming more prone to accept only employers with strong claims mancontinued on page 32

continued from page 30 agement and risk control engineering,” says Salazar. Employers with poor histories may have to go to the state pools for coverage. “These are pools you do not want to go swimming in,” says Salazar. “They are expensive. They charge standard premiums, adjusted for the employers’ experience, plus a 20 to 25 percent surcharge. And you do not get the same service. For example, there is no engineer to come in and help you manage your safety program.” Hire smart Employers can take a variety of steps to keep workers’ comp costs under control. Right out of the gate, say consultants, vetting potential hires can obviate problems down the road. “Change your hiring practices to reflect your drive to get people who value safety,“ says Ahlrichs. “It’s legitimate, for example, to ask safety related questions that are work related.” Also look at pre-hire assessments that can predict safety behaviors. It is valid to ask applicants to perform the activities required of a position, for example. “This is called a ‘fit for duty’ assessment,” says Salazar. “Can

Calculating the New X-Mod

Workers’ compensation premiums are rising at a rate of between two and five percent in many states this year. Reason? Several factors. One is the rising cost of medical care, translating into higher costs to return injured workers’ to health. Another is the departure from the market of some multiline insurance carriers, reducing competition for employers. There’s also a third factor: a change in the calculation for the “experience modification factor,” or x-mod, which is assigned to each employer. A higher x-mod translates into higher workers’ compensation premiums. The details of the change in the x-mod calculation can be found at the web site of the National Council on Compensation Insurance (ncci.com). Click on “Experience Rating Split Point” at the lower right corner of the screen. When calculating an employer’s x-mod, the states will look at three years of losses and payrolls. However, the most recent year is excluded. “The reason for that is that when a claim is made no one can predict the cost of the claim and set money aside to pay it,” says Salazar. “The reality is we have to see how the claim settles out.” Expect more costly x-mod adjustments ahead. “It is significant that the split point will continue to rise,” says Mike Salazar, Vice President and Manager of Client Services at Gregory & Appel. “It will move to $15,000 and adjust for inflation in future years.” Rising costs in workers’ comp seems to have the greatest effect on those employers without the resources to institute safety programs, or which have especially high costs of labor. “My experience has been that small businesses have a tough time absorbing these cost increases,” says Salazar. the applicant do the job safely based on its requirements?” Finally, conduct pre-employment

continued from page 32 ers’ comp claims,” says Salazar. “People who take drugs are more likely to have accidents, hurting themselves or others.” Drug abusers, too, can suffer from poor health. “Employees who are in poor health when they do have accidents usually end up with more expensive claims.” However, don’t fall into the trap of discrimination. It is improper, and illegal, to reject older applicants under the belief that they will have more accidents. “Older workers tend to work more safely than younger workers’ because they know the job better,” says Burton. It’s true that older workers, when they do get injured, often have costlier injuries because they do not heal as quickly as younger ones, notes Burton. However, this is offset by the fact that older workers tend to be higher paid and this correlates to higher premiums being collected in the workers’ compensation system. “In the aggregate older workers do not adversely affect the costs of workers’ comp.” Install safety programs Given that the x-mod rating is based on an employer’s accident record, it is wise to put an emphasis on workplace

Controlling costs at the state level

Nervous about rising workers’ compensation insurance? State governments are trying to do something about it. “Medical cost containment is one of the biggest topics this year in state legislatures,” says Peter Burton, Senior Division Executive for State Relations at the National Council on Compensation Insurance, Boca Raton, FL (ncci.com). “Medical fee schedules are being examined. States are also considering limiting the ability of physicians to dispense injured workers’ repackaged drugs that can be purchased much more inexpensively at the pharmacy.” There is also a major initiative by legislative organizations to place constraints on the abuse of prescription drugs, according to Burton. “More individuals die from overdoses of prescription drugs than from cocaine and heroin abuse.” “Because many injuries qualifying under workers’ compensation are traumatic in nature, drugs for pain relief are often prescribed,” says Burton. “This may be abused over time. Also, the longer workers stay on these drugs the longer it takes the injured workers’ to return to work.” safety, says Burton. “The message to the employers is this: Clean up your act, have a safe workplace and you are likely to reap greater benefits under the revised experience rating system.” Undertake a program of constant safety vigilance. “Hold a monthly meeting during which you review

continued from page 34 Many employers have redesigned their work stations, and introduced stretching and exercise programs to assure good employee health. “Strains and sprains, and slips and falls are the most common claims in workers’ comp industry,” says Salazar. “They can be engineered out of the workplace.” Wellness program can also play a role. “My sense is that there will emerge a body of data that links effective wellness programs with effective safety programs,” says Ahlrichs. “The combination should produce a great result on workers’ comp costs. Right now it’s difficult to find supporting data, but it makes sense that a company with a

focus on safety and well being will gain a competitive advantage.” Back to work Another good technique is to have early return to work programs for employees who have been medically restricted by physicians. The trick here is to identify alternative positions for which the injured worker is capable. “Suppose the worker has a medical restriction such as ‘Can’t lift more that 15 pounds,’” poses Salazar. “See if you have tasks that require lifting less than 15 pounds that you can assign the employee to while recovering.” There is an advantage to employees who cooperate, since most employers will compensate them at their normal salary, but only provide partial compensation to workers who stay

home. And there’s another reason: Adjustors will suspend the workers’ comp claims of employees who refuse temporary positions. “Workers’ comp is there for people who cannot work for medical reasons, not for those who refuse to work,” says Salazar. Can’t find a temporary position for an injured worker? Then keep open lines of communication with the home bound person. “Once people are hurt really badly they lose their desire to be part of a team,” says Free. “They feel forgotten and alone. Their spouses may be off at work while they are home with a broken leg. So we always tell our clients to visit them. Bring some fruit, talk for a half hour, show the person you care about him and want him back as soon as possible. That really helps. The little things that employers do make all the difference.” All of these steps together can communicate an attitude of caring. “Adopt policies that send the right message to your workforce,” says Ahlrichs. “Your message should be this: ‘We have a culture of safety. We attempt to control the variables so people do not get hurt. If you do get hurt we will get you back to work quickly.’ When that message gets out, people who are prone to accidents will apply at another business that does not make safety a front burner issue.” Get help Employers can seek help from consultants who specialize in workplace safety. “Some of these people go through special training,” says Free, who suggests employers look for designations such as “Associate in Loss Control Management” or “Certified Safety Professional.” Such people can teach employees in good workplace practices, including lifting properly and avoiding shoulder injuries. Consultants can make a big difference, but lay out parameters before the safety guru arrives. “One of the bad raps consultants get is that they make recommendations that are too expensive,” says Free. So emphasize you want suggestions on improvement that are cost neutral. “In such cases these improvements pay for themselves as losses go down.” A safe workplace can reduce your accident load and thus cap or even reduce your workers’ comp premiums as your x-mod improves. That’s all to the good. The cost of insurance is an integral component in competition, whether you produce a product or service. WRN

Preliminary steel imports decrease 14% in June

Import market share 23% in June Based on preliminary Census Bureau data, the American Iron and Steel Institute (AISI) reported that the U.S. imported a total of 2,442,000 net tons (NT) of steel in June, including 1,956,000 net tons (NT) of finished steel (down 14% and 9%, respectively, vs. May final data). Year-to-date (YTD) total and finished steel imports are 15,714,000 and 12,351,000 net tons (NT), respectively, down 11% and 9% vs. 2012. Annualized total and finished steel imports in 2013 would be 31.4 and 24.7 million NT, down 6% and 4% respectively vs. 2012. Finished steel import market share was an estimated 23% in June and is estimated at 23% YTD. Key finished steel products with a significant import increase in June 2013 compared to May are plates in coils (up 30%), mechanical tubing (up 18%) and hot rolled sheets (up 10%). In June, the largest volumes of finished steel imports from offshore were all from Asia and Europe. They were from South Korea (234,000 NT, down 17% vs. May final), China (153,000 NT, down 17%), Japan (129,000 NT, down 24%), Germany (106,000 NT, up 67%) and Turkey (99,000 NT, down 42%). For six months of 2013, the largest offshore suppliers were South Korea (1,752,000 NT, down 7%), Japan (955,000 NT, down 5%), China (896,000 NT, up 11%), Turkey (740,000 NT, down 18%) and Germany (556,000 NT, down 13%). Below are charts on estimated steel import market share in recent months and on finished steel imports from offshore by country.

AISI says USTR nominee would “work well with steel industry”

The American Iron and Steel Institute (AISI) said it was encouraged by the Senate Finance Committee hearing to confirm Michael Froman, one of President Obama’s key trade advisers, as the U.S. Trade Representative (USTR). Thomas J. Gibson, President and CEO of AISI, said he was pleased that Froman appears to be willing to listen to the concerns of the steel industry regarding the surge of steel imports, currency manipulation by a number of foreign countries, the trade disparities caused by state-owned enterprises and their government subsidies for manufacturing, and other un38

fair trade practices. “AISI works closely with the Office of the USTR and looks forward to continuing our open and frank dialogue to address the critical trade issues facing the industry. Michael Froman has been a responsive partner in ensuring the interests of the manufacturing sector are brought to the table. As the senators at the hearing heard today, he is a well-versed advocate for fair trade and will make an excellent trade ambassador,” Gibson said. Froman, who currently serves as Deputy National Security Adviser for International Economic Affairs, addressed the AISI Board of Directors at its November Board Meeting in Washington, D.C. He currently serves as an Assistant to the President and Deputy National Security Adviser for international economics, and has been deeply involved in the Obama administration’s international economic agenda for the past four years, working from the White House on the discussions for

Successful staging of Metallurgy Trade Fair quartet in Russia

At the recent staging of wire Russia 2013, International Wire and Cable Trade Fair in Russia, 250 exhibitors from 26 countries displayed their latest technologies at the Expocentre in Moscow. Held concurrently were Metallurgy-Litmash, Tube Russia and Aluminium/Non-Ferrous 2013 with 330 exhibitors from 30 nations and Russia Essen Welding & Cutting 2013. Some 10,850 visitors from all parts of the Russian Federation came to get a broad overview of pioneering trends. The positive development of wire Russia, Metallurgy-Litmash, Tube Russia, Aluminium/Non-Ferrous as

well as Russia Essen Welding & Cutting confirmed the importance of these trade fairs in the Russian Federation. The number of visitors shows that interest in an international specialist trade show for the wire, cable and wireprocessing industries as well as for the metallurgy, foundry and tube-processing industries has increased even further in Russia. These trade fairs provided the exhibiting companies with an excellent opportunity to present products until now not shown in Russia to a broad expert audience and to deepen customer relationships, get new contacts and develop new business. In addition to the individual exhibitors, countries such as Austria, China, France, Italy and the U.S. participated with country group exhibits again. As in the past, exhibitors from Germany took part in the official joint stand managed by the German Ministry of Economics and AUMA (Association of the German Trade Fair Industry). The North American group stand was organized by Messe Düsseldorf North America and supported by the Wire and Cable Industry Suppliers Association (WCISA). wire Russia, Metallurgy-Litmash, Tube Russia and Aluminium/ Non-Fer-

continued from previous page ahead of any others. The measure, introduced by Senator Rob Portman (ROH), calls for bridges that have been classified by the Federal Highway Administration (FHWA) as “functionally obsolete” or “structurally deficient” to receive priority consideration for new federal bridge funding under the $500 million “Bridges in Critical Corridors” fund. The new program is included in the Transportation and Housing and Urban Development (THUD) appropriations bill. Thomas J. Gibson, president and CEO of AISI, said, “Our nation’s infrastructure needs are at critical mass. According to the American Society of Civil Engineers, nearly 25 percent of our nation’s bridges are structurally deficient or functionally obsolete, and our deteriorating surface transportation infrastructure could cost the American economy more than 876,000 jobs. Investments in surface transportation directly impact the competitiveness of the manufacturing sector, especially by increasing demand for steel fabricated products which creates valuable steel jobs. Senator Portman’s amendment will help address this serious national concern and put

critical bridge repair funds where they are needed most.”

AISI calls on MTA to reconsider decision to use Chinese steel

The premier trade association representing North American steel producers asked the New York Metropolitan Transit Authority (MTA) to reconsider their decision to allow an expected 15,000 tons of steel plate made in China to be used in the upper deck replacement project for the Verrazano Narrows Bridge. In a letter to the MTA, Thomas J. Gibson, President and CEO of the American Iron and Steel Institute (AISI), said, “At a time when our nation remains in a recovery from high unemployment and economic recession, we cannot afford to ship American manufacturing jobs overseas. Sourcing 15,000 tons of steel from China for repairs on the Verrazano-Narrows Bridge is particularly offensive as the vast majority of Chinese steel companies are government-owned and controlled, and heavily subsidized. In addition, the Chinese government deliberately engages in unfair trading practices like currency manipulation to give Chinese

exports an unfair competitive advantage. We urge you to reconsider the decision.” Gibson cited a recent Wall Street Journal article entitled U.S. Icons Now Made of Chinese Steel, indicating that the Chinese trade association representatives tout their competitiveness against the North American industry. “The taxpayers of New York, and the many American tourists who cross the Verrazano Bridge, should not be forced to have their toll dollars go toward improving the economy of China when American manufacturing needs their support,” Gibson concluded.

AISI supports OCTG imports investigations filed today

The trade association representing North American steel producers lent its support to petitions filed with the Department of Commerce (DOC) and the International Trade Commissions (ITC) seeking antidumping relief on certain Oil Country Tubular Goods (OCTG) from India, Philippines, Saudi Arabia, South Korea, Taiwan, Thailand, Turkey, Ukraine and Vietnam. Petitioners are also seeking countervailing duties on certain OCTG from India and Turkey. Thomas J. Gibson, President and CEO of the American Iron and Steel Institute (AISI), said, “Imports from these countries have surged by 111 percent in the past few years, and the petitioners present that these imports have caused material injury to the domestic steel industry. U.S. laws against unfair trade exist to counter market-distorting practices – like subsidies – and to restore conditions of fair trade, but this cannot occur unless all parties play by the rules. It is vital for U.S. companies to have the chance to compete for business on a level playing field. We applaud these domestic steel companies for taking a stand and we urge the DOC and ITC to take a hard look and provide antidumping and countervailing duty relief for our industry.” Gibson said that in recent years the volume of U.S. imports of OCTG from the subject countries soared from 840,313 net tons (NT) in 2010 to 1,771,320 NT in 2012. In the first quarter of this year, 425,987 NT of imports entered the market from the subject countries. Petitioners include: Boomerang Tube; Energex Tube, a division of JMC Steel Group; Maverick Tube Corporation; Northwest Pipe Company; Tejas Tubular Products; TMK IPSCO; Unit-

ed States Steel Corporation; Vallourec Star, L.P.; Welded Tube USA, Inc.

Steel industry says climate plan will raise electricity costs

The trade association representing the nation’s largest steel producers said the plan laid out in President Obama’s speech on climate change “would place the steel industry at a substantial disadvantage to its foreign competitors and raise electricity costs.” “The regulations proposed by the President will invariably raise electricity costs and decrease service quality for major industrial customers, like the steel industry,” said Thomas J. Gibson, President and CEO of the American Iron and Steel Institute (AISI). “The North American steel industry is heavily dependent on affordable and reliable energy, which is typically 20 percent or more of the cost of making steel. We are the most energy efficient steel industry in the world, having voluntarily reduced our energy intensity by 27 percent since 1990. However, we compete globally against countries, like China, where the industry is often state-owned, controlled and subsidized, including for electricity costs. Policies, like those proposed by the President, raise energy costs on domestic companies and threaten our ability to remain competitive in this international manufacturing environment.” Gibson said that increasing regulations on the utility sector to force a quick reduction in carbon emissions is also unfair to many specific regions of the country and will encourage “fuelswitching,” since there are no proven technologies to control CO2 emissions from power plants: “The shift from coal to natural gas is already well underway due to the low price of natural gas and other EPA Clean Air Act regulations. However, certain areas of the country – including many of the states where there is a high concentration of steel production – have more abundant coal sources; whereas, other regions are better suited for production from wind and solar sources. The Administration’s plan makes coalfired electricity supply less affordable and less reliable to major industrial customers, such as steel producers – which will threaten the loss of valuable manufacturing jobs in the United States. We will be closely watching to see how EPA handles the transition period to minimize the cost and reliability impacts on regions that are still dependent on coal-intensive electricity generation.”

April steel shipments up 0.7 percent from March

Year-to-date shipments down 6.3 percent from prior year The American Iron and Steel Institute (AISI) reported that for the month of April 2013, U.S. steel mills shipped 7,978,531 net tons, a 0.7 percent increase from the 7,922,265 net tons shipped in the previous month, March 2013, and a 3.2 percent decrease from the 8,245,339 net tons shipped in April 2012. Shipments year-to-date (YTD) in 2013 are 31,547,910 net tons, a 6.3 percent decrease vs. 2012 shipments of 33,663,439 net tons for the first four months of the year. A comparison of April shipments to the previous month of March shows the following changes: cold rolled sheet, up 10 percent, hot dipped galvanized sheets and strip, up 5 percent and hot rolled sheet, down 4 percent.

July SIMA import permits down 6 percent, import market share 21 percent in July

Based on the Commerce Department’s most recent Steel Import Monitoring and Analysis (SIMA) data, the American Iron and Steel Institute (AISI) reported that steel import permit applications for the month of July total 2,476,000 net tons (NT). This was a 6% decrease from the 2,626,000 permit tons recorded in June and 1% increase from the June final imports total of 2,460,000 NT. Import permit tonnage for finished steel in July was 1,929,000, down 2% from the final imports total of 1,974,000 in June. For the first seven months of 2013 (including July SIMA), total and finished steel imports were 18,208,000 NT and 14,298,000 NT, respectively, down 11% and 10% from the same period in 2012. July 2013 total and finished steel import permit tons would annualize at 31,214,000 NT and 24,511,000 NT, down 7% and 5%, respectively, vs. the 33,475,000 NT and 25,826,000 NT imported in 2012. The estimated finished steel import market share in July was 21% and is 23% yearto-date (YTD). Finished steel imports with large increases in July permits vs. the June final included wire rods (up 74%), sheets and strip all other metallic coatings (up 31%), hot rolled sheets (up 27%), hot rolled bars (up 15%) and wire drawn (up 11%). Products with significant year-to-date (YTD) increases vs. the same period in 2012 include heavy structural shapes (up 25%), standard rail (up 18%) and tin plate (up 18%). continued on next page Wire Rope News & Sling Technology August 2013

continued from previous page In July, the largest finished steel import permit applications for offshore countries were for South Korea (268,000 NT, up 12% from June final), China (155,000 NT up 1%), Japan (140,000 NT, up 6%), Germany (90,000 NT, down 15%) and Taiwan (70,000 NT, up 30%). Through the first seven months of 2013, the largest offshore suppliers were South Korea (1,996,000 NT, down 11% from the same period in 2012), Japan (1,091,000 NT, down 9%) and China (1,053,000 NT, up 14%).

Lift-It Manufacturing provides international training

Michael J. Gelskey, Chief Executive Officer, Lift-It Manufacturing Co., Inc. presented two workshops for the EPRI 2013 Generation European Workshop in Rome, Italy. Mr. Gelskey presented an early morning session titled, Rigging for Success and another session in the afternoon that detailed Industry, Association and Regulatory Updates

from the American rigging perspective. Delegates from four continents attended the presentations and were enthused and extremely complimentary in their post conference evaluations. Mr. Gelskey remarked, “Thankfully, the attendees were far more advanced in their language skills than most of my United States students as the majority of the European attendees are bilingual.”

The one resounding comment that was received from the participants of both sessions was the passion Mike Gelskey has in presenting topics that will enable the attendees to make a difference in the lives of those they are tasked with protecting. Gelskey comments, “Long before it was fashionable or profitable, I would travel anywhere at my own expense to present sling and rigging training for anyone that would have me. Now, training is very much in vogue. My goal has always been to inspire and help my students leave with a new found perspective on the direct correlation that exists between rigging right and going home at night.” The first of many international presentations, Mr. Gelskey will follow up the European presentations with on site, sling and rigging training in the Dominican Republic and Australia.

This year, of particular interest, the representatives discussed the controversy over the CEN standard prEN 13001.3-2 titled “Limit states and proof of competence of wire ropes in reeving systems”. This controversy centers on a proposed theoretical approach to determining the life of a wire rope used on cranes versus the established wire rope design factors and discard criteria found in long-standing international standards, ISO 4308 Cranes and lifting appliances – Selection of wire ropes – Part 1: General and ISO 4309 Cranes – Wire ropes – Care and maintenance, inspection and discard. The material in the ISO standards relies on proven engineering practice and established criteria of wire ropes which can easily be used by inspectors in the field.

Inventorâ&#x20AC;&#x2122;s Corner By William Fischer

Lift system for an elevator Pat. 8,316,786 U.S. class 114/268 Int. class B63B 27/00 Inventors: William R. Johanek, Saint Simons Island, GA., Dale Hengel, Minneapolis, MN. Assignee: Par Systems, Inc., Shoreview, MN. A lift assembly is provided for a platform such as used on a ship. The platform can have four spaced apart hitch points. In one embodiment, the lift assembly includes four trolley drive assemblies, each trolley drive assembly including a trolley guidable along a guide rail, and a drive configured to displace the trolley along the guide rails, each trolley being coupled to at least one hitch point. In a second embodiment, a tension leveling assembly is provided in a trolley drive assembly and is configured to couple each of the wire ropes to the trolley and maintain substantially the same amount of tension in each wire rope. In a third embodiment, the lift assembly can be provided on a ship that also includes a vessel for holding water. The lift assembly includes an electric drive that operates as generator and generates current during lowering of the platform, A resistive device is disposed in the vessel and connected to the drive to receive current, the resistive device being configured to dissipate heat into the vessel. A lift mechanism 20 for, for example, a deck edge elevator platform 22 on a ship herein exemplified as an aircraft carrier 24 is schematically illustrated in figure 1. The platform 22 is suspended by wire ropes 26 at four hitch points 28A, 28B, 28C and 28D. At ends remote from the hitch points 28A-28D, the wire ropes 26 are connected to a lift assem-

bly 30 typically located internally in the aircraft carrier 24. Sheaves 32 located on the aircraft carrier at various locations guide the wire ropes 26 within the aircraft carrier 24 between the lift assembly 30 and the platform 22. It should be noted that guide rails 23 for the platform 22 are provided for only the inboard side of the platform 22 having hitch points 28A and 28D adjacent the edge of the aircraft carrier 24, while the outboard edge of the platform 22 having hitch points 28B and 28C is unguided, being only supported by the wire ropes for hitch points 28B and 28C. The lift assembly 30 includes four trolley drive assemblies

Figure 2: Side elevational view of a pair of trolley assemblies.

31A, 31B, 31C and 31D having trolleys 34A, 34B, 34C and 34D (schematically illustrated). Each trolley 34A-34D is driven by a drive 36A, 36B, 36C and 36D, respectively. The lift assembly 30, trolleys 34A-34D and drives 36A-36D will be discussed below in further detail; however, at this point, one aspect of the present invention includes minimizing and equalizing the load carried by each trolley 34A-34D during operation of the platform 22. In this manner, the load carrying capacity of each trolley drive assembly 31A-31D can be minimized and equalized. In operation, the loads carried by the wire ropes 26 for each of the hitch points 28A-28D are not all the same. In particular, wire rope loads for the outboard hitch points 28B and 28C are typically greater than the loads carried by the wire ropes 26 for inboard hitch points 28A and 28D. In order to balance the loads carried by each of the trolley assemblies 31A-31D, each trolley 34A-34D is connected to one inboard hitch point 28A or 28D as well as to one outboard hitch point 28B or 28C. In the embodiment illustrated, there are four wire ropes connected to each hitch point 28A-28D. For each hitch point 28A-28D, two wire ropes are connected to a first trolley, while the remaining two wire ropes are connected to another trolley. Although herein illustrated where two wire ropes are con-

nected to each trolley 34A-34D and corresponding hitch point 28A-28D, this construction should not be considered limiting wherein a single wire rope could be used although use of a plurality or ropes is beneficial. In one embodiment as illustrated, trolley 34A is connected to hitch points 28A and 28C; trolley 34B is connected to hitch points 28B and 28D; trolley 34C is connected to hitch points 28C and 28A; and trolley 34D is connected to hitch points 28D and 28B. Hence, in this embodiment, each trolley 34A-34D is connected to two hitch points 28A-28D that are on the same end (i.e., aft end or forward end of ship 24) of the platform 22. In an alternative embodiment, each trolley 34A-34D can be connected to inboard and outboard hitch points that are diagonally opposed to each other, although the wire roping would be more extensive. In the foregoing configurations when all four trolleys 34A-34D and corresponding drives 36A-36D are operating, each trolley 34A-34D and corresponding drive 36A-36D is coupled to an inboard hitch point and an outboard hitch point and lifts one-half of an end (forward or aft) of the platform 22. However, it should be noted that the lift assembly 30, which forms other aspects of the present invention, can be connected to the platform 22 in a manner where each trolley 34A-34D is connected to a single hitch point 28A-28D. In the exemplary embodiment, the sprocket 44 drives or displaces a chain 52, wherein one end of each chain 52 is connected to a trolley 34A-34D. (It should be noted only portions of the chains are illustrated in some of the figures to provide clarity for other elements.) Each trolley 34A-34D is guided by a guide rail, herein a pair of guide rails 53, in a support structure 54. As illustrated, the trolleys 34A-34D and the drives 36A-36D are organized in pairs facing each other wherein two trolleys are operable and utilize a common support structure 54 so as to minimize space. In one embodiment, each trolley 34A-34D traverses the support structure 54 substantially from one end to the other which corresponds to platform 22 moving from its lowermost position to its uppermost position and vice versa. To provide a compact lift assembly 30 and efficiently utilize available

space, the trolleys 34A-34D are stacked upon each other in pairs. In the embodiment illustrated, trolleys 34A and 34C comprise lower trolleys in each respective support structure 54, while trolleys 36B and 36D comprise upper trolleys in each respective support structure 54. Mechanical hard stops 62 are provided to limit extension of each corresponding chain 52, and further, to provide a hard stop for the platform 22 in its lowermost position. In its uppermost position, platform 22 is held by tension continued on next page

continued from previous page in the wire ropes 26 and corresponding chains 52 as each of the trolleys 34A-34D are pulled away from each of the corresponding mechanical stops 62 to the other end of the support structure 54. Brakes 46 are operated to hold the platform 22 in its uppermost position. Brakes 46 are configured to operate in a fail safe manner (for example, where the calipers 50 are held back in a non-braking position by a hydraulic, pneumatic or electrical device and are moved to a braking position by a spring) so as to actively hold the platform 22 when the power to the motors 40 is off or lost. One end of each chain 52 is connected to one of the trolleys 34A-34D. The other end of the chain 52 is connected to a second flexible member 68 (herein exemplified as a wire rope) that in turn, is connected back to the same trolley 34A-34D. Hence, the chain 52 and wire rope 68 of each trolley are connected to the trolley in order to form a single loop. Referring to figures 2 and 3, and to trolley 34C by way of example, the first end of the chain 52 is connected to the trolley 34C. This portion of the chain is held in tension by the gear reducer 42 and corresponding sprocket 44 of drive 36C. It should be noted, the pitch diameter of the sprocket 44 should be as small as possible to reduce the amount of torque needed for operation, and hence, the torque capability of the gear reducer 42. During operation, the trolley 34C traverses the support structure 54 from one end to the other. In figure 3, the trolley 34C is against its stop 62 and the platform 22 is in its lowermost position. Pulling of the chain 52 by the drive 36C to the right in figure 3 raises the platform 22. To control an end of the chain remote from the trolley 34C, the wire rope 68 is connected to the end of the chain 52, schematically illustrated in figure 1 and then back to the trolley 34C and secured at location 69 in figure 3. The wire rope 68 is guided by two sheaves 70 and 72 (one of which is illustrated in figure 1) into chain supports 74 and 76 which receive that portion of the chain which is not held in tension between the sprocket 44 and the trolley 34C. As indicated above, when the trolley is furthest away from its corresponding drive and resting upon mechanical stop 62, the chain 52 extends along the length of the support structure 54 between the sprocket 44 and the trolley 34C. As the trolley 34C is retracted toward its corresponding drive 36C, the wire rope 68, being attached to the trolley 34C, is also pulled in order to pull an end of the chain remote from the trolley 34C within guide support structure 54 and along corresponding chain support 74 and 76. In the embodiment illustrated, movement of the trolley 34C toward drive 36C eventually causes the platform 22 to contact hard stops 63 when it reaches the flight deck. The controller 80 is programmed to move the trolleys 34 an additional distance to tension the wire ropes 26 so the platform 22 is held tightly against the hard stops 63 and does not move as it is loaded or unloaded. If desired, a mechanical hard stop can be provided on the support structure 54 to correspond to the uppermost position of the platform 22. Rope locking device Pat. 8,321,998 U.S. class 24/134KA Int. class F16G 11/10 Inventor: Richard L. Warren, Tampa FL. Assignee: Roto Kinetics LLC., Clarkesville, GA. A tensioning device that is inexpensive to manufacture and is useful for various rope tensioning applications. The rope locking device can be used anywhere along a length of rope that is being used to hold, tie down, or secure a load 56

or item. The rope locking device includes: a body having a first end, a second end, and side ends; a first bore extending through the body; a second bore extending through the body, wherein the second bore is horizontally aligned and spaced apart from said first bore by a first space, wherein the first and second bore are located proximate to the first end of the body; a third bore extending through the body, wherein the third bore is located proximate to the second end of the body, and wherein the third bore is spaced from the first and second bores; a first slot vertically aligned with the first bore; a second slot vertically aligned with the second bore, wherein the second slot is spaced from the first slot by a second space; and a cam element pivotally mounted within the third bore. Figure 4 of the present invention shows the device 10, which comprises: a body 20 having a first end 30, a second end 40, and side ends 50, 60; a first bore 70 extending through the body 20; a second bore 80 extending through the body 20, wherein the second bore 80 is horizontally aligned and spaced apart from said first bore 70, wherein the first bore 70 and second bore 80 are located proximate to the first end 30 of the body 20; a third bore 90 extending through the body 20, wherein the third bore 90 is located proximate to the second end 40 of the body 20, and wherein the third bore 90 is spaced from the first bore 70 and second bore 80; a first slot 100 vertically aligned with the first bore 70; a second slot 110 vertically aligned with the second bore 80, wherein the second slot 110 is spaced from the first slot 100; and a cam element 120 pivotally mounted within the third bore 90. The body 20 may be made of a single piece having any desirable shape, preferably a rectangular shape, with a thickness sufficient to make the body rigid. The body 20 may be made of molded plastic, or a metal casting of aluminum or other tough, durable material such as a ceramic, hard resin, or a polymeric plastic material. Whenever heavier duty or

heavier strengths are required, metal is clearly the material of choice, although certain types of plastic material have been found to be quite durable and acceptable for certain structures for at least moderate duty. The first bore 70 and second bore 80 are parallel to each other. The first bore 70 and second bore 80 may be straight bores. In another embodiment of the present invention the Lshaped space 150 includes a plurality of teeth disposed in its internal size in order to further help grasp the rope. Cam element 120 is the only moving part of the device according to the present invention. The cam element 120 is pivotally mounted in the third bore 90 as illustrated on figures 4 and 5. For that purpose, an orifice 160 extends through one end of the cam element 120 to receive the dowel 140 for eccentrically mounting cam element 120 for pivoting. A recess 124 runs through the cam element 120 which receives a spring 170, as seen in figures 4 and 5. The cam element 120 may have one of its sides having a convexly curved shape and including teeth 122 in its periphery arranged at an angle to facilitate the grasping of the rope between the cam element 120 and one of the side walls 92 of the third bore 90. The teeth 122 of the cam element 120 and the side wall 92 of the third bore 90 are spaced apart a sufficient distance to allow pivoting of the cam element 120 into the third bore 90 and the grasping of the rope in its locked position. The utilization of teeth arranged at an angle permits to freely slide the rope in the non-locking position and securing the rope in the locked position. In another embodiment of the present invention the clamping element 120 pivots about the dowel 140 and is biased downwardly by a spring 170 to project into the third bore 90. The biasing force of the spring 170 may be manually overcome to pivot the cam element 120 in order to allow insertion of any portion along the length of a rope into the device. Figure 6 shows the sequence in which the rope is introduced into the device according to the present invention. First, a length of rope is drawn through the first bore 70 in either a first or an oppositely directed second direction. Second, the length of rope leaving the first bore 70 is looped back through the first slot 100 and over the space 150 between the first slot 100 and the second slot 110. Third, the end of the rope passes the second slot 110 and loops 90. The multiple bends in the rope through the bores 70, 80 and slots 100, 110 assist in providing additional locking of the rope in the desired position to prevent the slippage of continued on next page

continued from previous page rope in the load direction. The unique design of the present invention has the advantage of providing a double locking feature for the rope: 1) the multiples bend on the rope through the bores and slots, and 2) the cam element. Both locking systems work together to prevent the slippage of the rope and allow placing the device at any position along the length of the rope when tensioning is desired back through the second bore 80. Fourth, a loop of a desired length is formed and the remaining rope is routed through the space between the cam element 120 and the side wall 92 of the third bore. When the cam element 120 is in the closed position it partially blocks the space between the clamp element 120 and side wall 92 of the third bore 90 and locks the rope. When the cam element is in the opened position it does not block the space between the clamp element 120 and side wall 92 of the third bore 90 and does not engage or contact the rope; thus, the rope may be freely pulled through the passageway in either the first or the second direction. Thus, the device according to the present invention is used to shorten the effective length of the rope between the two ends of the rope until it is pulled tight. At this time, the cam element 120 is pressed downwardly by the spring 170 to cause the teeth 122 to firmly bite into the rope firmly holding it in place. Any attempt to move the pre-selected length of rope (loop) located between the second bore 80 and the

cam element 120 further increases the clamping action of the device; so accidental loosening of the desired loop of rope does not occur. Changes in the size desired loop of rope cannot occur unless the cam element 120 is manually raised to disengage it from the rope. Hoist line protector (updated) Pat. 8,359,714 U.S. class 24/136R Int. class F16B 2/14 Inventor: Grover Edward James Harper, Wildwood, CA. Assignee: Grover Edward James Harper, Wildwood, CA. Disclosed is an apparatus for enclosing the free distal end of a flexible tensile member supporting an object. The flexible tensile member has a first portion in tension for suspending the object, and a free end substantially perpendicular thereto with the object between it. The apparatus comprises a body having a passage sized to slidably receive the first portion of the flexible tensile member therein a bottom edge adapted to engage the object and a void for enclosing the free distal end of the flexible tensile member wherein the bottom edge is engaged with the object. Referring to figure 7, an apparatus according to a first embodiment of the invention for enclosing the distal end of a crane line, or end protector, is shown generally at 30. The end protector 30 comprises a body extending between top and bottom ends, 32 and 34, respectively. The end protector has a passage 36 extending along a passage axis 38 between the top and bottom ends 32 and 34 for receiving the first or load bearing portion 8 of the cable 10 and a void 80 therein for receiving the free distal end 6 of the crane cable 10. The end protector 30 includes an edge surface 40 extending along one edge thereof between the top and bottom ends 32 and 34 and first and second side surfaces, 42 and 44, respectively. The passage 36 is defined by first and second walls 50 and 60, respectively extending from the edge surface 40. As illustrated, the second wall 60 extends from the second side surface 44 and includes a first portion 62 substantially parallel to the second side surface 44 and a second portion 64 substantially perpendicular to the first portion 62 and substantially parallel to the edge surface 40. Similarly, the first wall 50 comprises a first portion 52 extending sub-

stantially parallel to the first side surface 42 and a second portion 54 substantially perpendicular thereto. The first and second walls 50 and 60 cooperate with the edge surface 40 to retain the load carrying portion 8 of the crane cable 10 within the passage 36. As illustrated, the first portions 52 and 62 of the first and second walls 50 and 60 are continuous with the second portions 54 and 64 along a continuous arc about the passage axis 38. However, it will be appreciated that in other embodiments, the first and second portions may also be distinct from each other and will therefore form a segmented wall. In embodiments where the first and second portions are continuous, a distal edge 66 of the second portions may also extend back towards the edge surface 40. In such embodiments, the curvature of the wall, such as illustrated with reference to the second wall 60 may exceed 90 degrees as measured from parallel to the second side surface 44. In other embodiments having distinct first and second portions, the second portion may include a lip so as to assist in retaining the cable 10 within the passage 36. The first wall 50 extends between top and bottom edges 56 and 58 and the second wall extends between top and bottom edges 68 and 70. The first and second walls 50 and 60 are spaced apart so as to form a gap 72 between the bottom edge 58 of the first wall and the top edge 68 of the second wall. Accordingly, the first and second walls 50 and 60 are spaced Figure 9: Front elevation view of the end protector being applied to a load bearing portion of a crane cable above a socket and wedge assembly.

apart along the axis 38 of the passage. The gap 72 may be transverse or substantially perpendicular to the axis 38 as illustrated although it will be appreciated that other orientations relative to the axis 38 may be utilized as well. The gap 72 has a width sufficient for the cable 10 to pass through so as to locate the cable within the passage 36. The first portions 52 and 62 of the first and second walls 50 and 60 cooperate to enclose the cable 10 within the passage 36. As illustrated the first and second walls 50 and 60 are located on opposed sides of the passage 36 wherein the second portions 54 and 64 are oriented towards each other. The void 80 is sized and shaped to receive the free distal end 6 of the cable 10 as set out above. The void 80 is formed into the end protector 30 extending from the bottom end 34. As illustrated, the bottom end 34 may include a cavity 82 sized and shaped to receive a clip 28 as are known in the art therein. The void 80 extends from a bottom aperture 84 adjacent to the cavity 82 in a direction towards the top end 32 of the end protector 30. With reference to figure 8, the void 80 may extend through the end protector to the top end 32 so as to have an top aperture 86 therein. It will also be appreciated that in some embodiments, the void 80 may be a blind bore having no top aperture. The void 80 is formed by a pair of spaced apart side walls 88 and first and second end walls 90 and 92, respectively. The side walls have a constant distance between them and are oriented in a direction corresponding to the first and second side surfaces 42 and 44 of the end protector although a taper may be useful in some embodiments as well. The spacing between the side walls 88 may be selected to correspond to the thickness of the cable 10 with which the end protector 30 is to be used. The first and second end walls 90 and 92 may be substantially planar or may have a curvature or any other shape as will be appreciated. The first and second end walls 90 and 92 may be angularly oriented towards each continued on next page Wire Rope News & Sling Technology August 2013

other to form a taper angle, generally indicated at 94 in figure 8. The taper angle 94 may be selected so as to cause the free distal end 6 of the cable 10 to bear against the second end wall 92 when the body is placed thereover so as to assist in frictionally retaining the end protector 30 on the socket and wedge assembly 12. The end protector 30 may optionally include a keeper 100 for retaining the end protector in contact with the socket and wedge assembly 12. As illustrated in the attached Figures, the keeper 100 may comprise a tab 102 having a bore 104 therethrough sized to receive a cotter pin (not shown), or other suitable fastener. The bore 104 may be located such that a cotter pin passes through and engages upon the underside of bolts of the clasp as are known in the art. Other keepers 100 may comprise a tab 106 extending from the bottom end 34 of the end protector 30 parallel to the second wall 60. The bracing tab 106 is locatable to an opposite side of the socket and wedge assembly so as to prevent the second wall from rotating out of contact with the cable 10. The bracing 60

Wire Rope News & Sling Technology August 2013

tab 106 may be located adjacent to the passage 36 or distally through it. In operation, a user may locate the gap 70 of the end protector about a load bearing portion 8 of a cable above a socket and wedge assembly as illustrated in figure 9. Thereafter, the end protector 30 may be rotated in a direction indicated generally at 110 to bring the first and second walls 50 and 60 into contact with the load bearing portion 8 and thereby to locate the passage 36 around the load bearing portion. The end protector 30 may then be moved in a generally downward direction indicated generally at 112 so as to locate the free distal end 6 of the cable within the void 80 as illustrated in figure 10. Wire rope flaw detector for increasing accuracy independent of speed while conserving detector size (updated) Pat. 8,390,281 U.S. class 324/240 Int. class G01N 27/82 Inventor: Takashi Yoshioka, Tokyo, JP., Hiroshi Sasai, Tokyo, JP., Koichiro Nishiyori, Tokyo, JP. Assignee: Mitsubishi Electric Corporation, Chiyoda-Ku, Tokyo, JP. A magnetic flux generated by current excitation is allowed to pass through a part of or an entire magnetic path of a leakage magnetic flux. A magnetic flux content due to the current excitation is temporally changed to change a leakage magnetic flux content interlinked with a detection coil so that an induced voltage is generated in the detection coil. Consequently, damage can be detected even in a case where there is no relative speed between a wire rope and a wire rope flaw detector. Further, a configuration of the magnetic path and the number of ampere turns of an exciting coil are set to be appropriate to prevent the magnetic flux generated by the current excitation from passing through the detection coil or to allow the magnetic fluxes to offset each other. Thus, noise superimposition on the detection coil due to the current excitation can be prevented. In figure 11, a wire rope 1 and a wire rope flaw detector 2 are illustrated. Further, a back yoke 3, an excitation permanent magnet 4b, and a protecting plate 6 are illustrated. Figure 12 is a perspective view illustrating the exterior when the protecting plate is detached from the wire rope flaw detector of figure 11. Figure 12 illustrates the back yoke 3, the excitation permanent magnets 4a and 4b, a support 5, the protecting plate 6 detached from the wire rope flaw detector, a magnetic path member 7, a detection coil 8, and an exciting coil 9.

exciting power source 11, a main magnetic flux 12, a leakage magnetic flux 13, and an excitation current magnetic flux 14. A damage detection unit of the wire rope flaw detector 2 includes the magnetic path member 7, the detection coil 8, the exciting coil 9, and the exciting power source 11. Figure 15 is an enlarged diagram illustrating a cross section of the magnetic path member of figures 13 and 14. Figure 15 illustrates the magnetic path member 7 including a bypass magnetic path member 7x and a loop magnetic path member 7y, the detection coil 8, the exciting coil 9, the exciting power source 11, a bypass magnetic path 15 formed in the bypass magnetic path member 7x, a loop magnetic path 16 formed in the loop magnetic path member 7y, and a common portion 22 of the bypass magnetic path member 7x and the loop magnetic path member 7y. The wire rope flaw detector 2 according to this embodiment forms the main magnetic path in a given section in the axial direction of the wire rope 1 by means of the magnetization unit. Further, the wire rope flaw detector 2 allows the leakage magnetic flux 13 generated by the damaged portion 10 of the wire rope 1 to go around the outside of the wire rope 1 through the magnetic path member 7, and detects the leakage magnetic flux 13 by means of the detection coil 8 wound around the bypass magnetic path member 7x of the magnetic path member 7. Figure 15 is the enlarged diagram illustrating the cross section of the magnetic path member 7 of figures 13 and 14, as described above. The magnetic path member 7 forms the

Figure 15: Enlarged diagram illustrating a cross section of a magnetic path member.

bypass magnetic path 15 that allows the leakage magnetic flux to go around as well as the loop magnetic path 16. The exciting coil 9 is wound around the loop magnetic path member 7y that forms the loop magnetic path 16, and when the exciting coil 9 is energized, the loop magnetic path member 7y is magnetically saturated to deteriorate the permeability. Therefore, a part of the bypass magnetic path 15 is mag62

Wire Rope News & Sling Technology August 2013

netically blocked. For that reason, the leakage magnetic flux content interlinked with the detection coil 8 is reduced to develop an induced voltage in the detection coil 8. In this way, a change in the leakage magnetic flux content interlinked with the detection coil 8 can be caused by a temporal change in the exciting coil current. Therefore, a relative speed between the wire rope 1 and the wire rope flaw detector 2 is not required, and even when the relative speed is low, the damaged portion 10 generated in the wire rope 1 can be detected with high precision. As illustrated in figure 12, surfaces of the excitation permanent magnets 4a and 4b, which face the wire rope 1, each have a substantially U-shaped surface with R in which a slight margin is added to the outer diameter of the wire rope 1 and the thickness of the protecting plate 6. The reason is that an air gap (including the protecting plate 6) between

Figure 16: Perspective view illustrating the exterior when the protecting plate is detached from the wire rope flaw detector.

each of the excitation permanent magnets 4a and 4b and the wire rope 1 is minimized to thereby effectively magnetically saturate the given section of the wire rope 1. Figure 16 is a perspective view illustrating the exterior when the protecting plate is detached from the wire rope flaw detector of figure 11. The excitation permanent magnet 4a may include, as illustrated in figure 16, a cuboid wire rope excitation main magnet 17a, cuboid wire rope excitation sub-magnets 18a and 18b, and a magnetic pole piece 19a made of a ferromagnetic material. Further, the excitation permanent magnet 4b may include a cuboid wire rope excitation main magnet 17b, cuboid wire rope excitation sub-magnets 18c and 18d, and a magnetic pole piece 19b made of a ferromagnetic material. As a result, because most of the permanent magnetic configuration is cuboid, the processing costs can be reduced. The magnetic path member 7 includes the bypass magnetic path member 7x that is made of a ferromagnetic material and allows the leakage magnetic flux 13 generated by the damaged portion 10 of the wire rope 1 to go around the outside of the wire rope 1, and the loop magnetic path member 7y that contains a part of the bypass magnetic path member 7x and forms a closed loop magnetic path by itself. The magnetic path member 7 is disposed between the pair of excitation permanent magnets 4a and 4b and immediately below the protecting plate 6. Because the bypass magnetic path member 7x is made of a ferromagnetic material, the permeance of the magnetic path of the leakage magnetic flux 13 can be improved to bring out a large amount of the leakage magnetic flux 13.

As illustrated in figure 18, in this embodiment, the rope main body impregnated with the impregnating solution is heated at 40°C or more and 180°C or less to thermally expand the strands 6, and the impregnating solution penetrates gaps between wires in the strands 6, the gaps being generated by the thermal expansion. Further heating is carried out to react and harden the hydroxy compound having two or more hydroxy groups per molecule and the isocyanate compound having two or more isocyanate groups per molecule in the impregnating solution, to thereby fill the gaps in the strands 6 or the valley parts between wires in the strands 6 where the air layer 8 is liable to appear with the impregnating solution-hardened product 9. Subsequently, the rope main body is covered with the covering resin layer 7 including the molded product of the composition for forming a covering resin layer, which is produced by mixing the thermoplastic polyurethane elastomer, the thermoplastic resin other than the thermoplastic polyurethane elastomer and the isocyanate compound having two or more isocyanate groups per molecule, to thereby obtain an elevator rope without generating the air layer 8. In the thus-obtained elevator rope, even in the case where frictional heat is suddenly generated, such as at the time of an emergency stop of the elevator, heat is easily released, and temperature change on the friction interface becomes small, resulting in a small variation in the friction coefficient.

Figure 19: Schematic cross-sectional view of the vicinity of an outer layer of an elevator rope.

The viscosity of the impregnating solution before complete hardening is adjusted so as to be lower than the melt viscosity of the composition for forming a covering resin layer. In the case where the viscosity of the impregnating solution before complete hardening is higher than the melt viscosity of the composition for forming a covering resin layer, it is impossible to fill gaps in the strands 6 or valley parts between wires in the strands 6 where the air layer 8 is liable to appear. The viscosity of the impregnating solution is appropriately adjusted depending on the composition of the composition for forming a covering resin layer and the like, but is usually 500 mPas or more and 20,000 mPas or less, preferably 2,000 mPas or more and 5,000 mPas or less. The abovementioned viscosity ranges are lower than the melt viscosity of a general thermoplastic polyurethane elastomer, and hence the impregnating solution can fill small gaps which are not filled by covering with the covering resin layer 7. Meanwhile, in order to improve the thermal conductivity of the impregnating solution-hardened product 9, a thermally conductive inorganic filler may be added to the impregnating solution. The thermally conductive inorganic filler is not particularly limited, and examples thereof include boron nitride, aluminum nitride, silicon carbide, silicon nitride, alumina, and silica. Of those, boron nitride and aluminum nitride are more preferred because of high thermal conductivity. In addition, the blending amount of the thermally conductive inorganic filler is not particularly limited. When a rope including steel wires having a multilayer structure is impregnated with the impregnating solution before covering the outermost periphery with the covering resin layer and heated at from 40°C or more to 180°C or less, the impregnating solution-hardened product can be filled even if there are gaps between the steel wires in the rope outermost layer and the resin cladding where the steel wires in the outermost layer are twisted. Figure 19 is a schematic cross-sectional view of the vicinity of an outer layer of an elevator rope which is obtained by forming an impregnating solution-hardened product by the abovementioned method before covering with an outer layer cladding. In figure 19, the numeral 9 denotes the impregnating solution-hardened product, the numeral 10 denotes the outer layer cladding, the numeral 11 denotes an outer layer strand, and the numeral 12 denotes an inner layer cladding. The outer layer strands 11 are each structured by a center wire disposed in the center and six peripheral wires disposed on the periphery of the center wire. Gaps between wires in the outer layer strands 11 and gaps between

An elongated hole 24 in the flange 42 of socket 5 (visible in figure 25 through oval access opening 44 in the opposite sidewall of socket 5) defines spaces 46a and 46b between shaft 21 and flange 42. Shear pin 7 normally carries the force from socket 5 to frame 8. When shear pin 7 fails, socket 5 will pivot relative to frame 8 about drum shaft 14; this provides tactile feedback to the user that the shear pin has failed, which indicates that the safe load has been

exceeded. Hole 24 provides a containment mechanism when the shear pin fails, as pawl shaft 21 will move through space 46a or space 46b and then contact the edge of hole 24 to prevent further rotation of the socket relative to the frame. This allows full control of the hoist and the load after shear pin failure. Elongated hole 24 allows limited, defined handle movement relative to pawl shaft 21. Upon failure of shear pin 7, the elongation of hole 24 provides enough movement to clearly indicate through tactile feedback that an overload condition has been reached.

Shear pin 7 must be capable of resisting loads within the desired range, while providing an appropriate shear load and shear characteristics. 5/16’’ round cold drawn steel of low to medium carbon content is an appropriate material. Pressed and sintered powdered ferrous materials also may be used. A groove 31 of approximately 0.080’’ width and 0.083’’ depth accomplishes a reduced diameter of 0.146’’ in

the pin shear region. The shear pin is held in place in the frame and socket by use of retaining rings 23. Alternate designs of the shear pin can use a head on one end of the pin and other means of retention of the pin in the frame and socket (e.g., a receiving cavity for the head and screw threads on the other end of the pin) to allow for easier changing of the pin after failure.

winches capable of opening the lock in 3 to 4 minutes. It is within these sliding gates that, 226 Crosby® sheaves, 64.37in./1635mm in diameter with a 1.81in./46mm wireline, will be used. McKissick® Roll-Forged™ sheaves were chosen for this contract for a number of reasons. They are lighter, stronger and more wear-resistant due to our roll-forged process. Sheaves produced under this roll-forged method are more economical because less welding and machining are involved compared to conventional methods. These sheaves can be made lighter because the rolling process incorporates upsetting the sheave. The upsetting operation allows material to be gathered where needed, in order to support the rope, as opposed to starting with a thicker blank. Our sheaves are manufactured out of different materials in order to meet demanding requirements such as Charpy Impact Testing and rigorous hardness requirements in the groove. Crosby® is the only company who can manufacture a superior roll-forged sheave by the use of our proprietary upset rollforged process. Crosby McKissick® Products began manufacturing sheaves and blocks for the oilfield industry in the 1920’s and is now the largest supplier of aftermarket replacement sheaves for both landbased and offshore drilling companies. The McKissick® brand is recognized worldwide as a quality product that is designed specifically to withstand harsh applications.

Hand pallet truck accessible palletizer makes loading easier than ever

The PalletPal Roll-In™ Level Loader from Southworth is a manual palletizer that makes loading and unloading full pallets easier than ever, according to a company release. Thanks to its unique low-profile, openended platform, the Roll-In allows the forks of an ordinary hand pallet truck to literally roll into it, in between the platform’s outer beams and a center support beam, while the pallet ends up on top of the scissor-lift platform. This innovative design, which accommodates loads on any open-bottom pallet or skid, ensures that the load is evenly placed when the hand truck is lowered and rolled away. The Roll-In Level Loader reduces costs and raises productivity. Because workers can feed and offload it with a hand pallet truck, they don’t

waste time waiting for a forklift and trained operator to assist them. A powered foot switch allows smooth, hands-free adjustment of the platform to the most comfortable height as boxes are added or removed, reducing worker fatigue and injuries. The platform can be accessed from all four sides with no bending and minimal reach-over. A full-perimeter, auto-stop toe guard provides an added measure of safety. The Roll-In Level Loader has a 2,200 lb. capacity, lowered height of 3¼ inches, 31½ inch raised height, 48 x 53 inch platform. For more information, contact Brian E.
