Compact Concepts By Katie Parrish and Guy Ramsey
By Richard Howes 2060 Vision
Looking for the right aerial work platform to meet the needs of a job may require users to think beyond traditional self-propelled scissors and boom lifts. For work sites that require a machine to fit in tight areas, provide low ground pressure, and work indoors and outside, track-mounted compact aerial lifts may be the best solution.
31 Product Focus What’s Under Your Hook?
Proper handling is essential to safe crane operations, and for many crane users, accessories like under-hook attachments are necessary to perform the job. Handling coils and steel plates, for example, may require custom-built grabs to manage the load. Additionally, lifting devices like shackles eliminate crowding around the master link, which ultimately makes the work area safer. This roundup of products includes information to make your job easier, as well as company news from manufacturers and suppliers.

economic forecasts, we tend to spend a lot of our lives planning for the future. For example, we know that throughput at U.S. ports is on an upswing and should continue to improve in the next few years as global economies—therefore, freight volumes—recover, and ports continue to prepare for the Panama Canal expansion project to be completed in 2014. That year will see the second MODEX trade show, which will be introduced by the Material Handling Industry of America (MHIA) in Atlanta, Ga., next February. The biennial show will alternate with Chicago’s ProMat 2013, ’15, and so forth. Georgia is the home to nearly 11,000 providers of logistics services from core transportation and facilities to third-party logistics and software providers. The Port of Savannah is the fourth-largest container port and the fastest growing container port in the United States with 2.6 million TEU (Twenty-foot Equivalent Units) annually. The Panama Canal expansion, which will accommodate 12,000-TEU ships, is set to reshape global trade patterns and be a major supply chain game-changer for the east coast of the United States, according to the MHIA. Despite all this diligent forward planning, few of us have dared gaze as far into the future as 2060, which was the focal point of Cargotec, Helsinki, Finland, at TOC Europe, a shipping, ports and terminals conference and exhibition, staged in June in Antwerp, Belgium. Its “Port 2060” vision (cargotec.com/port2060) aims to give a futuristic view of containerization in around 50 years time. By 2060, Cargotec says, mega ports will be located offshore on artificial islands where layouts can be optimized. Floating feeder/river terminals that can be moved around in line with changing demands will support these ports. The container itself will remain in use, it says, based on the same compact, standardized format, but different materials might be used, while containers could be foldable and may have built-in intelligence to communicate destination, contents, and journey details. One of the most interesting ideas generated by the Port 2060 project is that fully automatic lashing systems could form different container packages with up to 64 containers in a single moveable unit. Container crane lift capacities, it says, could increase from around 40-100 tonnes today to 1,000-2,000 tonnes, so they could handle such container packages in a single lift. Container storage could take place in terminals located in underground silos, as land will be at a premium by 2060. While some current container ship designs will still be in operation, the majority of container vessels of the future will be fully automated, Cargotec says, or they will have a small crew with numerous energy-saving features, including solar technology. They also will be designed so that a container block can be separated from the vessels if needed, allowing them to then pick up another cargo block and sail on. Within the Port 2060 environment, automation is virtually the sole mode of operation. Artificial intelligence, widely used in daily life in 2060, will monitor port processes, thereby optimizing performance. Cargo-handling systems will use alternative energy sources or electric drives, and wheels will have been replaced by air cushion or magnetic levitation technologies. Handling equipment will have its own consciousness, allowing it to monitor wear and tear, and it will be able to order its own maintenance and repairs remotely. Give this theme scope and ponder what your foundries and mills; alternative and traditional energy sites, such as solar, wind, and petrochemical; aerospace facilities; mines; and other manufacturing plants will look like 50 years from now. Are you daunted or ready for the next chapter of evolution?

ICHC Houston Exhibitor Offerings
More than 40 exhibitors, representing crane and rigging manufacturers, load indication suppliers, training companies, certification groups, and more, will participate in the Reach Expo. A preview of some of those companies follows. A current list of exhibitors and sponsors is found at www.ReachExpo2011.com. Ace World Companies, Fort Worth, Texas, is looking to expand its global distribution network. “We want to export our crane components to capable crane builders in more countries than we have in the past,” says Camron Ghanemi, chief operating officer. “Australia, the Middle East, and Asia are a focus for us. Countries such as China and India can source standard products locally much cheaper than they can get them from us; so our focus is on the sophisticated equipment they don’t specialize in.” Product development remains on a fast-track program. Ace launched its new Advantage crane kits and chain hoists last year and have since expanded the line to include more options. It started the line with 5 and 10 ton wire rope hoists with a standard 30-foot lift and has since added 3 and 7.5 ton hoists and up to 70-foot lifts. “We have also developed a VFD chain hoist for both single and three phase units, and have a VFD option for the motorized trolley as well,” says Ghanemi. Ghanemi calls the launch of Ace’s new Terminator T60 units this year “one of our greatest accomplishments.” This is the second phase of its Terminator T30 line. The T30 series goes from 5 to 50 ton capacities and has longer lift and faster speed options. “They are no longer just top running trolley hoists either, as we have added base mount and monorail options as well.” aceworldcompanies.com Bishop Lifting Products (BLP), Houston, Texas, which is a 2011 Event Partner for CRC and ICHC, announces the addition of a 150,000-pound portable proof test truck to its fleet of testing equipment. The portable test bed allows the company to perform on-site proof testing, repair, and RFID tagging services at the customer’s location, reducing downtime and costs for the customer. The 20-foot long bed is designed to test all types of slings (Twin-Path, wire rope, synthetic, metal mesh, roundslings, alloy chain, and high performance), rigging

hardware, oilfield tools, crane and snatch blocks. The test bed is also equipped with a mechanical wire rope gripper for testing winch lines, raising lines, and pendant lines. It can also be used on the deck of marine vessels if needed. All BLP service technicians are trained in inspection and testing of lifting equipment in accordance with current industry standards and manufacturers’ recommendations. Customers may choose to proof test lifting equipment at given intervals, or for verification purposes due to recent repair, modification, or dormancy. Once all testing has been completed, testing certificates can be retrieved on prooftesting.com with a login and password to provide customers 24/7 access to certificates. lifting.com Crane Inspection & Certification Bureau (CICB), which is a 2011 Event Partner for CRC and ICHC, announces it has moved to an additional location in Houston, Texas, inside the Holt Crane & Equipment Link-Belt Complex at Loop 610 East and Homestead Road. The facility includes two classrooms that can accommodate up to 40 students. Cranes and rigging gear for hands-on training, practice sessions, and written and practical examinations include small hydraulic fixed cab, large hydraulic swing cab, lattice boom crane, and overhead cranes as well as a variety of rigging gear and loads. CICB offers training programs at its Houston facilities or the customer’s location.

Demag to Supply Two Mobile Harbor Cranes to Canada Demag Cranes, Dusseldorf, Germany, has received an order to supply two mobile harbor cranes to Canada. The two identical machines are four-rope grab cranes for professional bulk handling. Mining and metals giant Vale Inco Limited (Vale), a new Demag Cranes customer, will be using the cranes for handling nickel and limestone at its terminal in Long Harbor (southeast Newfoundland and Labrador). The G HMK 6407 B mobile harbor crane with the four-rope grab is a variant of the Model 6 harbor crane. Designed to withstand the rigors of high-end use, Model 6 harbor cranes are for high-performance applications and thus achieve enhanced handling rates. This four-rope grab G HMK 6407 B variant has a 50-tonne grab curve in A8 classification and, depending on the local conditions, achieves handling rates of up to 1000 tph. “The bulk market offers tremendous potential and has, for some years, been a focal point in our port technology segment,” said Thomas Hagen, member of the management board of Demag Cranes AG. “Around a quarter of the Gottwald Harbor Cranes sold last year are for professional bulk handling. The considerable strategic importance to Demag Cranes of the bulk-handling market is also reflected in the acquisition of the UK company DB Controls. That company has renowned capabilities in software and advisory services in the field of automating bulk-handling equipment. This acquisition has further extended our range of services in this key segment of the market.”

The German-headquartered certification organization TÜV SÜD’s certified experts and technical consultants optimize technology, systems, and expertise at more than 600 locations in Europe, America, and Asia. Third party certification of safety functions assures the customers of the manufacturer’s ability to design, test, and maintain specific levels of safety in the entire products’ lifecycle, Autec said. The stop function in the Dynamic Series complies with requirements of EN ISO 13849-1 Performance Level “e”, Cat. 4 and EN IEC 62061 Safety Integrity Level 3. The UMFS function (that protects actuators from Unintended Movement From their Standstill) meets PL “d”, Cat. 3 / SIL2. The Stop function takes the machine to its “safe state,” even if a fault on the radio remote control should occur. The UMFS function protects against movements that are not deliberately activated by the user, even in the case of a fault in the remote control. The Dynamic Series can be used in a vast range of mobile hydraulic applications, including machines that involve the lifting of people, as it meets high functional safety standards. All the models in the Dynamic Series undergo severe tests and inspections to prove their robustness even in extreme working conditions (high/low temperature, vibrations, shocks, chemical agents) and offer IP 65 protection against water and dust.

IPAF Report: U.S. Powered Access Rentals will Rise 11 Percent in 2012 Rental revenues for aerial work platforms (AWPs) in the US decreased 4 percent in 2010, to about $5.7 billion. But they are expected to grow five percent in 2011, and 11 percent in 2012, according to the IPAF US Powered Access Rental Report 2011. “There are strong indicators for a real recovery of a somewhat embattled AWP market in recent months,” said IPAF CEO Tim Whiteman. “The U.S. market is seen to be more mature, more generalist, more concentrated and is expected to recover more rapidly than Europe.” The results are based on independent studies conducted by Ducker Research, which used interviews as its main research. The sample of rental companies interviewed represents about 60 percent of the estimated total AWP rental market. The reports are presented in an easy-to-read format that highlights key facts and figures, such as fleet size, utilization rate, and retention period. New for this year is the analysis of fleet mix, comparing the proportion of scissors and booms. Booms represent about 40 percent and scissors about 60 percent of the U.S. AWP fleet. No change in the mix is expected during the next few years. The IPAF U.S. Powered Access Rental Report 2011 can be purchased at ipaf.org/reports.

,
ndustrial ift oist like many of our readers’ suppliers and manufacturers of the equipment in their facilities, is a member of the Material Handling Industry of America (MHIA). The MHIA is the largest U.S. material handling and logistics association representing the leading providers of material handling
Material Handling-Related Standards and the MHIA MHIA is accredited by the American National Standards Institute (ANSI) to oversee and coordinate the development of American National Standards, but does not cover all areas of material handling. Standards for hoists and cranes (ASME), conveyors (CEMA, ASME), corrugated containers (ASTM, TAPPI), and many other types of material handling products and equipment are developed through other ANSI-accredited standards developing organizations (SDOs). In addition to the ASME led standards on hoists and cranes, the Crane Manufacturers Association of America (CMAA, an affiliated trade association of MHIA) has also developed a highly respected and widely used set of specifications (Spec 70, 74, and 78). Although they are not ANSI-accredited standards, these specifications play a very similar role in their service to the industry. They simply don’t follow the full MHIA or ANSI development procedures as outlined below.
ANSI + Accredited Developers + Experts = Standards Keep in mind that ANSI does not develop, write, or review the technical content of standards. ANSI leaves that work up to organizations that they accredit to perform the process. MHIA, as an accredited standards developing organization, acts as a facilitator to aid groups of MHIA member companies and other companies/organizations in the development of standards. ANSI determines whether open and fair procedures were followed in developing each standard, plus they perform regular audits of developers.

and logistics solutions. ‘Solutions that make the supply chain work’ is its catchline. Here, in the latest of a series of articles submitted by the MHIA, Mike Ogle, vice president, educational and technical services, explains the MHIA’s role in the development of a wide range of material handling standards.
By Mike Ogle, Vice President, Educational and Technical Services, Material Handling Industry of America
Development Procedure Types
MHIA facilitates standards development using two types of procedures, each based on serving a particular type of standards reviewer group. Canvass Procedures. The first set of procedures, known as the canvass method, is the one used by product groups within the MHIA umbrella. Although MHIA product groups will develop and vote on draft standards, they serve as only the first step in the process. The canvass method requires formation of a separate canvass group to review and vote on a standard. By the time that the canvass group is formed, an MHIA product group has already developed and internally approved a standard. External, open, public review is required by ANSI. Any individual or organization that is materially affected by the proposed standard has an opportunity to become part of the canvass group. The canvass groups generally are formed and operate only during a single development and maintenance cycle of a particular standard. They are then essentially disbanded until the next revision or reaffirmation of the standard. MHIA currently has 22 standards approved and under development using this method of standards development. Committee Procedures. The second type of procedure is known as the committee method. Committees are formed for a longer term, continuous commitment to a family of standards and typically include many other organizations and entities from inside and outside MHIA (mostly outside). MHI currently serves as secretariat for three standards developing committees on pallets, unit-load and transportpackages, and freight containers as described below.
MHIA Administered Standards Committees (National and International) MH10 Committee on Unit-Loads and Transport Packages United States Technical Advisory Group (USTAG) to Technical Committee (TC) 122 Packaging MHI serves as the secretariat for the accredited standards developing committee MH10: Unit-Loads and Transport-Packages. The scope of the committee effort is as follows: “To facilitate freight movement within transportation and distribution systems by providing standards for transport-packages and unit-loads, including their dimensions, definitions, terminology, coding, labeling, and performance criteria; and to represent the United States’ interests within the scope of ISO/TC 122 - Packaging” The MHI role in MH10 and other similar committee method focused standards groups is to facilitate and coordinate the overall committee efforts. Committee activity primarily takes place through subcommittees concentrating on unit-load and transport-package issues such as: sizes, heights, testing, terminology, and coding and labeling. Working groups may be formed by subcommittees to tackle more specific issues. MHIA hosts an annual meeting for the membership, typically held in New York in May.

Association Update
The MH10 committee is also the US Technical Advisory Group (USTAG) to ANSI for ISO/TC 122 – Packaging. The TC stands for Technical Committee. In this capacity, MH10 acts as the U.S. voice to the international standards development community concerning packaging issues. MHIA and the U.S. have hosted multiple international group meetings. MHI is now also administering a subcommittee MH10.4 on Packaging and Environment to serve as the U.S. voice on packaging/environmental/sustainability issues. A series of seven standards will be developed by this subcommittee. MHIA and the U.S. hosted the most recent international meeting of this group during the first week of May 2011. Expected completion of the standards is in 2012. USTAG to TC 104 Committee on Freight Containers MHI serves as secretariat for the accredited USTAG to TC 104 on Freight Containers. Freight containers are the multimodal workhorse of the flow of goods internationally. I serve as administrator for the group in a similar role to the one performed for MH10. There are no standards produced at the national level for this group because of the international nature of the products. The scope of the committee’s work is: “Standardization of freight containers, having an external volume of one cubic meter (35.3 cubic feet) and greater, as regards terminology, classification, dimensions, specifications, test methods and marking.” This group tends to do all of its business by email and rarely holds physical meetings other than attending the international meetings. MHIA and the U.S. recently hosted the international TC 104 group meetings in January 2011. MH1 Committee on Pallets, Slip Sheets and Other Bases for Unit Loads USTAG to TC 51 Pallets for Unit Load Method of Materials Handling In 2005, ASME transferred administration to MHI for the MH1 (that is a one, not an “I”) Committee on Pallets, Slip Sheets and Other Bases for Unit Loads. Given the role of pallets in material handling, this was a great addition to MHIA’s standards efforts. MHIA also serves as Secretariat for the USTAG to TC 51 Committee that develops and maintains pallet standards at the international level. MHIA hosts an annual meeting for the membership, typically held in Washington in May. MHIA and the U.S. hosted the international TC 51 group meetings in November 2008.
Finding Standards
You can find the standards that are administered by MHI by going to the Material Handling Institute bookstore at www.mhia.org/bookstore and then clicking on the category “Specifications, Standards and Testing.” You can find nearly every national and international standard within ANSI’s search tool at www.nssn.org. The site allows you to enter partial document numbers, keywords, title words, etc. as search options. It is a valuable tool for anyone involved in standards development or looking for standards applicable to their work.

Jungheinrich Walkie Straddle Stacker Added to North American Product Line Mitsubishi Caterpillar Forklift America Inc. (MCFA), Houston, Texas, has added the Jungheinrich EJC B14/EJC B16 heavy-duty electric walkie straddle stacker to its North American product line. The Walkie Stacker implements an efficient threephase AC technology drive system, proportional lift and lower control, optional electric power steering, and a multi-function control tiller head. Jungheinrich engineers focused on increasing energy efficiency and reducing life cycle costs with the AC technology drive system. Enhancements include proprietary software, enhanced electrical components, and optimized cable routing, which result in longer battery life and more run time. Further advantages include the elimination of wear items such as motor brushes and springs, which can lead to lower life cycle costs, and advanced regenerative braking, which allows energy to be fed back into the battery for longer run times and enhanced productivity. The EJC Series also integrates quiet performance and handling, as precise speed and torque control allows for easy maneuvering even in confined warehouse applications. The series features variable lift/lower speed control which lowers pull-down and putaway costs while reducing the likelihood of lift truck, rack or product damage. All forklift movements are accomplished via the tiller head, as it allows for increased operational efficiencies and decreased operator fatigue. The tiller head is mounted low and toward the side of the truck. This maximizes the space between the operator and the chassis for increased comfort and visibility. The controls may be activated with either hand to further increase operational efficiency of the forklift. The EJC B14 and EJC B16 also feature patented dual articulating load wheel design, a crawl speed button that allows travel with handle in the upright position, and an auto-reversing switch. Optional features include adjustable baseleg widths, a cold store package for refrigeration and freezer applications, and electric power steering, which minimizes the amount of effort required to turn the truck, reducing operator fatigue. jungheinrich-lift.com

Magnetek’s Flex M Receiver Communicates with Impulse Drives Magnetek Inc., Menomonee Falls, Wis., announces the availability of its new Radio Drive Serial Interface (RDSI) module for its Flex M receiver. The RDSI module was designed to allow users to communicate with the company’s Impulse drives through a serial interface, reducing system cost by eliminating relay cards, wiring, and labor. Communication to any number of drives is achieved with only three wires. When combined with Magnetek transmitters such as the XLTX and the soon-to-be-released MLTX2, operators interfacing with a Flex M with RDSI module can now monitor performance parameters such as drive status, torque reference, and output frequency, voltage, current, and power, right on their transmitter’s display unit. No need to get up on the crane to obtain diagnostic information. The compact Flex M wireless receiver, compatible with most Magnetek transmitters, features a modular, plug-and-play design which allows one plant to use the same type of receiver component for any size application. Mountable modules are combined to create a flexible, expandable radio receiver system that meets the requirements of a variety of applications, from simple relay outputs to complex I/O and communication networks. “We are very excited to add the RDSI module as an option for our Flex M receivers,” said Ben Stoller, radio controls director for Magnetek. “Not only does the ability to communicate serially with our Impulse drives reduce total system cost but it provides our customers with diagnostic and troubleshooting information on the ground when paired with one of our transmitters with LCD graphic display.” magnetek.com

Bosch Rexroth Electronic System Solution Saves on Fuel Use High dynamic response of the travel drive and implement hydraulics, on mobile equipment even at reduced diesel engine speeds, and for Tier 4 final engines, is the goal Rexroth has achieved with its Diesel Hydraulic Control (DHC). Developed together with the diesel engine specialists from Bosch, this electronic Bodas system solution for engine management and drive and working hydraulics reduces diesel fuel consumption by up to 20 percent. The Tier 4 emissions regulations for mobile work equipment, due to take effect in 2014, will likely result in significantly poorer load response of diesel engines. Furthermore, manufacturers of excavators, telehandlers, and other mobile equipment are reducing engine speeds to conserve diesel fuel. The control devices used until now for the drive and working hydraulics cannot compensate for this sluggishness. The potential risk is lower productivity. With DHC, Rexroth has teamed with Bosch to develop a new control strategy which retains the accustomed lively response of the travel drive and implement hydraulics even under conditions of diminished load response and lower engine speeds. DHC changes the traditional function sequence and lets the diesel engine know of expected load requirements. This is accomplished using matched controllers from Bosch for engine management and from Rexroth for the travel drive and implement hydraulics, using a common special map. This DHC system map represents the vehicle-specific relationships between rpms, efficiency, and torque. Diesel Hydraulic Control continuously determines the demands of the travel drive and implements hydraulics, and uses this information to dynamically calculate the optimal operating points for the diesel engine and hydraulic components by means of the DHC system map. In practice, the joystick for the implement hydraulics, for example, transmits pending work requirements directly to the DHC, which in turn
22 Industrial Lift & Hoist
passes this requirement to the diesel ECU. This allows the engine time to prepare for the imminent mechanical load. The world’s first combined controller solution compensates in this way for the expected poorer load response of Tier 4 final diesel engines. At the same time DHC makes it possible to operate the equipment at the accustomed dynamic response levels in spite of lower engine speeds, thereby saving fuel. Since DHC means that the diesel engine only provides as much power as the machine actually needs at any given moment, diesel fuel consumption is reduced compared with current figures. Fuel savings of up to 20 percent as measured in real-life testing will reduce the total cost of ownership for operators with no sacrifice in dynamic response of the travel drive and implement hydraulics. boschrexroth.com

Transferring spent fuel casks. The
-
self propelled modular transporter from Wheelift Systems, Waverly, Iowa, is designed to increase levels of safety and efficiency while transferring and aligning spent fuel casks at independent spent fuel storage installation facilities. The Wheelift SPMT reduces worker exposure by requiring fewer people to operate, align, and insert the cask. Only one person is needed to operate the transporter from as far as 50 feet away. According to Wheelift, the transporter’s omni-directional steering and 10-inch lift capability allows the same operator to perform alignments remotely to within 1/32 of an inch and eliminates the need for an independent leveling and alignment system. The transporter uses an onboard diesel-driven generator to supply the transporter’s electric power. This generator also provides power for the transfer cask ram’s hydraulic power unit. An alternative shore power connector is available for quiet operation as a backup system while aligning and loading spent fuel. The Wheelift transporter uses a custom-designed cask support skid on top of its deck with the push cylinder fitted with an electrically actuated grapple to eliminate the possibility of a broken hydraulic line that could potentially contaminate the HSM. Constellation Energy’s Ginna Nuclear Plant in upstate New York was the first to use the Wheelift transporters in its NUHOMS spent fuel storage operations. The project to install a nuclear-fueled drive on site involved loading and transporting a number of canisters to a facility that can store them long term. “For the first time, we used a [Wheelift] self-propelled transporter,” said Bryan Flynn, project manager for the Ginna independent spent fuel storage installation (ISFSI) project. “The transporter is capable of handling the entire canister load, which is approximately 125 tons fully loaded. This canister is in a horizontal position and had to be transported a quarter of a mile outside on a designated heavy haul path in order to take the fuel from where it is loaded in our spent fuel pool to the final location where long-term storage modules are located.” He said the company saw the self-propelled modular transporter as a
July/August 2011 • industrialliftandhoist.com
significant upgrade to the existing self-leveling trailer and cab that would normally be used for these types of projects. “We saw this as an upgrade for several reasons,” Flynn said. “First, from a safety standpoint, the modular transporter involves the ability to be controlled from a distance from the transporter while it is moving, minimizing radiation dose to the employees. It also does not contain mechanical linkage to drive the tires together that several of the transporters have, which have been problematic.” Another benefit of the Wheelift SPMT is its omni-directional travel capability, which allows increased maneuverability in tight spaces. According to Flynn, the SPMT is able to level and adjust to tight tolerances, so a separate leveling system is not required to align to the horizontal storage module. Because each axle and wheel is independently controlled, the transporter can travel forward, backward, laterally, at an angle, and rotate on nearly any surface while fully loaded. This capability allows for greater storage density and utilization of the space needed for ISFSI storage facilities without losing the ability to align the NUHOMS casks with the HSM. Tug and trailer technology typically requires 70 feet of space between the HSM modules. Wheelift’s SPMTs can operate in 35 to 40 feet, allowing greater storage efficiency for current and future storage needs. The transfer cask can be removed from the Wheelift transporter deck to allow the unit to perform other heavy haul tasks as needed. This multi-task versatility can augment or eliminate other heavy lifting equipment such as cranes. “We’ve seen other uses for the transporter,” Flynn said. “We’re currently looking at making alternate skids for a refueling outage to move other heavy components with the transporter.” He noted that after completing four campaigns with the self-propelled modular transporter, the company has had no significant issues with the transporter. Maintenance and safety personnel also said they have a good level of confidence in the equipment. “The degree of added safety, fast precision alignment, and effortless movement throughout the process has totally changed our approach to spent fuel handling,” Flynn added.

Proper Use of Choker Hitches
For riggers, there’s more than one correct way to choke a load.

Symmetrical or nesting choke
Nothing
stirs up heated discussions among riggers more than the proper use of the choker hitch. If you put an ironworker and an industrial rigger together on the same job, they’ll get along famously until they need to choke a load. The ironworker will probably insist that the eyes must be counter to each other without the use of shackles, while the industrial rigger will be adamant about the opposite. The reason for the difference of opinion? The ironworker’s main goal is to lift a piece square, while the rigger is looking to control the location of the choke points. The two also will likely differ on the use of shackles when choking. The ironworker needs to be able to disconnect with a minimum of body motions. Using shackles increases the difficulty of unhooking so the ironworker prefers to rig the sling wire-through-eye. The damage to the wire rope caused by not using shackles is a price paid to increase body-positioning safety on the high

steel. However, the gear needs to be inspected and replaced at a much greater frequency than “normal.” The rigger, on the other hand, might be looking for more strength and protection of the gear. He’ll usually use a nesting choke with shackles while the ironworker will use the leveling choke without shackles. Which way is right? They both are. It just depends on what you want from your sling configuration.To start, the choker is the most useful arrangement if you need grip. The heavier the load, the tighter the grip. However, the heavier the load, the weaker the sling becomes. Depending on the shape of the object being wrapped around, some charts reduce the working load limit (WLL) of a choked sling by as much as 50 percent of singleleg WLL. This reduction is due to bending and pinching of the sling body. Another disadvantage is the need for a constant strain being applied to keep the grip tight. If you get sudden deceleration,
there is a good chance the choker will lose its grip and slide away from the spot where you placed it. The introduction of sling angles on multi-leg chokers can tend to pull the sling off position. The grip itself can even be a disadvantage; if the load is delicate a choker could crush it. The nesting choke can be used for flipping plates from horizontal to vertical.

Slings Characteristics of chokers
To better understand the nature of chokers, I’ve identified several common characteristics of this sling configuration. With a nesting choke, the slings pass under the load from the same direction. One advantage of this technique is the ability of a single worker to hold the choke tight and in place as the slings tighten. This technique is particularly good for nesting a bundle of pipe or structural members that are spread out on their dunnage but need to be consolidated into a single bundle. But be careful, bundled pieces can pinch. Another appropriate use of this configuration is for flipping plates from horizontal to vertical. Both chokes grab at the same time as the strain is applied. A third application is for rolling round pieces one quarter or less of a turn. Words of warning: Trying to go further than that could cause the piece to roll uncontrollably. Use a round turn if possible.
No amount of choking or settling of the bundle can guarantee all the internal pieces are gripped tight.
With a stopped choke, the slings are held in place by the structure of the load. Several safety considerations must be understood here. First, the part of the piece that stops the choke must be strong enough to withstand the lifting force of the sling and the sliding pressure the sling puts on the piece. The lifter must avoid pinch points, which act like shears and will damage or cut through the sling. The sling must be protected from sharp edges. For a stopped choke you can get away with slightly tighter sling angles since there is a positive stop on the choke sliding into the center of the load. You can usually rely on sling angles down to 45°, and with careful stress calculations and gear protectors, you can go tighter. But do 1:00:58 not goPMbelow 30°! 338wide_mag_sunset.pdf 1 9/30/2009

However, if the choke points are not anchored on the edges of the piece, the piece can roll in either direction, and one of the chokes is sure to go slack.
Come-a-longs Trolleys Slings Beam Clamps
With a leveling choke, the slings pass under the load from opposite directions. The advantage of this technique is the ability to lift square pieces level. The disadvantage is the need for two workers to hold correct choke position and tightness as the slings tighten. In addition it is difficult to get the two slings to share the weight evenly. With a sliding choke, the slings are held in place only by the friction of the load. Because the choke depends on friction and grip to hold its position, any relaxation of either can result in one or both of the chokes sliding out of position. Ultimately, the load could be lost. With this configuration, it’s best to keep the horizontal sling angle at a minimum. As the horizontal sling angle increases you will be putting more pulling stress on the choke. It’s best to keep your sling angle above 60° off the horizontal. Do not go below 45°!

Tips and techniques
When positioning the choke, it is best to place the slings so that the load is picked up evenly with an equal weight distribution in the slings and the body of the load. Each sling should be one quarter in from the ends of a uniformly weighted piece. This puts each sling in the middle of its half of the piece. In addition, it helps to have dunnage just inside the one-quarter mark. When you are placing your wraps around the load, the dunnage keeps it from sliding past that point. Working the choke means tightening or loosening the sling. The direction you pull the standing part in relation to the bearing point of the choke has an effect on how the choke tightens or loosens. The more you break the standing part back over the eye, the tighter the choke gets. In reverse, the more you pull into the throat of the eye, the looser the choke gets. There is no purpose to forcing the choke by bashing it with anything other than your hand. The little extra grip you think you get with this brutal technique is paid for by extreme damage to the standing part of your sling. If you need more grip use a round turn.
26 Industrial Lift & Hoist
Round turns or double wrapping increases grip and lessens the chance of sliding. It provides more surface contact between the sling and the load. However, there is a price to pay for using this technique. The sling length is effectively shortened by the length of the round turn. This can result in tighter sling angles. Also, care should be taken that the sling is not pinched or trapped by itself. It should be free to render around the piece until a strain is taken. Round turns or double wraps
industrialliftandhoist.com • July/August 2011
Slings Hooks can also be used to choke. For a round turn, wrap the slings so that the standing part is toward the center of the load. This will prevent the standing part from bearing down on the round turn and possibly trapping some slack in the round turn. The throat opening of the hook must face outwards or away from the center of the piece. This causes the standing part to bear more fully into the throat of the hook. Don’t rely on the safety latch to hold the sling in the hook. They only have enough strength to keep a slack sling from jumping out of a hook.
Compare the load compression using a round turn (left) and a choker (right).
Bad example of using shackles when choking with wire rope.
Good example
Finally, it is a really good idea to use shackles or hard eyes when choking with wire rope. If you don’t, your wire rope will start to look like a bad-hair-day spring. (Synthetics and chain don’t usually need a shackle.) When using a shackle to connect an eye to the standing part in a choke, you must be careful which direction you place the shackle. Look at the two pictures above. Can you see why? If you place the shackle as found in the top picture you will have the pin running against the standing part. As the choke is pulled tight there is the possibility of the shackle pin spinning and coming unscrewed. Armed with this information, hopefully jobsite arguments about the best way to choke a load will be settled and riggers and ironworkers will be able to select the best configuration for their situation. The ultimate goal is to rig a load in the safest, most practical way.

Compact Concepts The ultra compact Platform Basket fits in extremely narrow areas indoors and out.
Crawler-mounted aerial lifts incorporate unique access characteristics.
By Katie Parrish and Guy Ramsey
Looking for the right aerial work platform to meet the needs
of a job may require users to think beyond traditional self-propelled scissors and boom lifts. For work sites that require a machine to fit in tight areas, provide low ground pressure, and work indoors and outside, trackmounted compact aerial lifts may be the best solution. We look at the features and benefits of some of the most unique models on the market, including those manufactured by Skako Lift, Niftylift, Ommelift, and Platform Basket. Compact track-mounted aerial lifts feature three concepts that when combined set these units apart from all other access equipment. The first characteristic is narrow access, which also may be found in other equipment, such as wheeled compact machines or scissor lifts. Extremely low floor impact is the second concept these machine incorporate, and track-mounted compact aerials often have the ground pressure that is roughly the same as a human—about 5-10 psi. With such a low ground pressure, the aerial lift can traverse over delicate surfaces indoor and outdoor, including turf, wood parquet, and polished marble. Although low floor pressure can be found with other equipment, it is only combined with the narrow access of these machines. The final characteristic is the ability to drive and deploy the machine on extreme up-, down-, and side-hill inclines. This characteristic can be shared by other outrigger-deployed atrium lifts, but traditional wheeled
28 Industrial Lift & Hoist
atrium lifts do not have the ability to go uphill on severely varied terrain. In this unique package, track-mounted aerials can go through an extremely narrow opening, climb over delicate, sloped surfaces, and set up for work. Its characteristics make it a useful tool to perform a variety of challenging personnel lifting tasks. Manufacturers often offer several variations in a product class. Although these machines are similar in style, they are all unique in their offerings. The following information discusses the features and benefits of popular models available in North America. With a 99-foot platform height and 52 feet of outreach, the Reachmaster Falcon FS105-Z retracts to a surprisingly compact 39 inches wide.
Niftylift TD34TN
U.K.-based Niftylift has been present in the U.S. aerial lift market since the 1990s and opened its American service and support facility about six years ago in Greer S.C. Among its tracked lift product offerings, the TD34TN is Niftylift’s smallest machine. The narrow TD34TN’s chassis retracts to 2'6" wide, enabling it to fit through tight areas. With the tracks extended, the TD34TN measures 3'9". It has a 34-foot platform height and nearly 21 feet of side reach when elevated 15 feet. The unit can be powered by fuel or AC power. It has a Kubota diesel power engine, as well as a 110V-powered hydraulic system as standard. In indoor applications, all boom Among functions can be performed by its tracked plugging the unit into a 110V lift product outlet. offerings, the narrow TD34TN Niftylift’s TD45TN features is Niftylift’s “straight-line” hydraulic controls smallest that are fully proportional. With machine. these mechanically activated proportional controls, the operator does not rely on electronics for machine functions. Niftylift also says that a simple hydraulic control system makes the machine easy to maintain, operate, and considerably reduces the number of computer modules needed for troubleshooting or repair. This machine has a single-person, 30"x26" basket with 300-pound capacity. The boom has 358° noncontinuous rotation. As standard, the upper control box has an extended control cord, allowing the operator to walk behind the machine. The TD34TN has 60 percent gradeability, allowing the unit to climb a flight of stairs or over a severe incline. The unit is not self-leveling, which Niftylift says keeps the user in control of all leveling functions. Safety features include micro-switches in the outrigger pads that will sound an alarm if the machine is not level. Unlike other tracked lift manufacturers, Niftylift allows users full range of function when the alarm sounds rather than shutting down the machine. Niftylift offers the machine with black or non-marking, rubber-free urethane tracks for clean, internal applications. industrialliftandhoist.com • July/August 2011
Personnel Lifts Ommelift 2350RJ
The Ommelift 2350RJ, distributed by Tracked Lifts Inc., Syosset, N.Y., takes the atrium lift concept and applies it to general indoor and outdoor use. The unit can fit through a 4-foot door to perform interior maintenance on delicate surfaces, but it also has the capability of traversing and deploying in areas that are extremely sloped. The 2350RJ is a true hybrid machine, using a Kubota diesel engine to power all hydraulic functions while simultaneously recharging the onboard battery pack that powers the unit’s alternative DC operational system. Both systems are independent and have their own hydraulic pumps. In case of a pump or power failure, the lift will still be fully operational. Under battery power, the boom can be used, depending on demand, from three to six hours without the need to be recharged. If the batteries are depleted, the operator has the option of turning on the diesel engine or plugging into a 110V power source and continuing to use electric power.
The boom’s main telescopic extension cylinder is located underneath the boom where it is protected from materials that can cause damage to the pistons. Additionally, the boom does not need to be greased or disassembled for wear pad replacement. Wear pads are external. Outriggers can be patterned in several different positions, allowing the machine to deploy in varied spaces. The travel length of the piston in the hydraulic cylinder and extreme angle of the outrigger allow the machine to be positioned on sloped terrain up to 40 percent. Automatic leveling is not an option. The travel lock must be opened for the machine to operate. In order for the boom to extend, the outriggers must meet the ground, the machine must be level within 2°, and the travel lock has to be on. Basic machine operation occurs with joysticks that electrically actuate the hydraulic valves. Operation is governed by simple off-the-shelf relays that can be swapped or replaced if they burn out. A single-person or two-person rotating basket is available. The unit weighs 6,700 pounds; an optional variable width undercarriage increases the weight to 7,300 pounds. Biodegradeable hydraulic oil is standard on this machine.
Platform Basket 18.90

July/August 2011 • industrialliftandhoist.com
Platform Basket 18.90, offered in North America by Tracked Lifts Inc., Syosset, N.Y., is part of the company’s ultra compact range. The unit will fit through a 32-inch-wide, 6'7" tall door. Built in Northern Italy, the Platform Basket 18.90 uses very few electronics, with mechanically linked levers controlling the hydraulic functions. Safety features that detect ground pressure, outrigger and boom position, and maximum allowable work moment are monitored through electro-mechanical limit switches.
Industrial Lift & Hoist

Trends &Technology To enhance safety, the boom will not deploy if all four outriggers are not touching the ground and detecting ground pressure. Also, if the outriggers are deployed but the machine is not level within 2°, the boom cannot be elevated. Automatic-leveling systems are available as an option but not encouraged by the company. To achieve narrow configuration, the undercarriage will retract to 31 inches, which brings down the height to 6'3". The outrigger pads can be removed to achieve its narrow width. The 18.90 is powered by either a Honda gasoline engine or a 19-amp, 110V electric motor. Each system powers its own hydraulic pumps, making the power systems redundant in case there is a failure. If the machine is hooked up to a 110V outlet, power is also available in the platform. Two hoses that run through the boom supply air, water, or hydraulics to the basket. When the 18.90 climbs a severe grade, the lowest point of the machine could come into contact with the ground when the trailing boom section angles downward. To prevent the boom from damaging delicate surfaces, a roller is located on the lowest point on the boom. To protect the cylinders, Platform Basket incorporates a heavy shield to prevent damage caused by falling objects or paint, concrete, stucco, or other building materials that could harm the piston or cylinder seals. Other sensitive components such as the engine, electric motor, valve block, and relay box have steel shielding. Optional equipment includes white rubber trucks, larger outrigger pads, and biodegradeable oil.
Reachmaster Falcon FS105-Z
Introduced in 2010, the Reachmaster Falcon FS105-Z from Skako Lift Inc., Kingwood, Texas, features 99 feet of platform height and 52 feet of outreach. The unit retracts to a surprisingly compact 39 inches wide and
30 Industrial Lift & Hoist
Personnel Lifts climbs an 18° slope, fitting the compact aerial lift criteria. As a dual-powered unit, the FS105-Z runs on four maintenance-free gel batteries or a Kubota water-cooled diesel engine. When it is engine powered, it has a separate hydraulic pump, providing more power for driving, operation, and climbing steep grades. If the machine needs to be used in an area where diesel fumes are not permitted or inside areas on floors capable of supporting the 11,000-pound machine, it can be operated on battery power or plugged into a 110V outlet. When plugged into an outlet, 110V power is available to the operator in the platform. To operate the machine, the outriggers are deployed by removing a safety latch. For safety, outriggers cannot be operated until all four have been manually swung to the deployed position. Note the boom must be completely stowed for the outriggers to operate. Once the boom comes off the safety switch, only the expandable track system can extend and retract. If an outrigger becomes light while the FS105-Z is elevated, weight sensors on the outriggers will illuminate. At that point, boom outreach will be limited, and machine operation will prevent further movement in an unsafe direction. The machine currently does not have an outrigger auto-level system, but it may be available as an option in the future. Other safety features include dual-holding valves on cylinders with positive and negative movement. As the machine is operated, there is a slight delay so pressure can build up in the supply line to the cylinder and sufficiently release the holding valve. This eliminates any chance of back pressure when the valve opens, thus providing a more positive control response. Controls are electric over hydraulic, and the joystick is proportional. Push buttons are used for each function. The lift can be driven from the platform, but outriggers can only be deployed from the ground controls.

Cranes
What’s Under Your Hook? Lift your load correctly with the right rigging gear, lifting devices, and attachments.
Proper handling is essential to safe crane operations, and for
many crane users, accessories like under-hook attachments are necessary to perform the job. Handling coils and steel plates, for example, may require custom-built grabs to manage the load. Additionally, lifting devices like shackles eliminate crowding around the master link, which ultimately makes the work area safer. Read on for a roundup of products available to make your job easier, as well as company news from manufacturers and suppliers.
News and New Products 30,000-Pound Gripping Tong for Work Rolls in a Steel Mill
Bushman AvonTec, Milwaukee, Wis., designed and built a 30,000-pound capacity gripping tong grab to handle work rolls in a steel mill. The tong includes chock stabilizers that prevent the top-heavy chocks on the ends of the roll from flipping over. Operation is mechanical, using Bushman AvonTec’s automatic latching device. In recent months, Bushman also has launched a motorized coil/pallet lifter that can lift both eye-horizontal coils and palletized vertical coils. The unit has fork assemblies to lift pallets and coil lifting saddles for lifting horizontal coils. The forks and lifting pads are motorized to permit changeover on-the-fly or when used with a cab-operated crane. When lifting coils on pallets, a set of motorized coil restrictors lowers to prevent tall coils from shifting on the pallet. Sensors detect when either type of load is lifted to prevent accidental opening of the legs while carrying a coil. Other sensors and indicator lights aid the operator in aligning the lifter with the coil or pallet. Numerous coil protection features are also included. One example has the motor control enclosure attached to the grab. This enclosure can also be mounted on the crane. Capacity for palletized coils is 33,000 pounds, and up to 100,000 pounds for eye-horizontal coils. Additionally, the company has developed a coil grab for handling densely packed slit coils. Its customer, Coilplus-Berwick Steel, Columbus, Ohio, needed to find a way to insert and remove thin slit steel coils (down to 1 inch wide) from a storage rack. The coils are closely stacked in the rack with a narrow 1.5-inch space between them. The hooks are adjustable in two-inch increments to handle coils of varying thickness. “The main advantage of these lifters is that the feet rotate,” said Larry Wood, maintenance and safety coordinator at Coilplus. To remove a coil, the hooks are lowered with the feet parallel to the coils. Once the feet are in the coil, they are turned 90 degrees so they can lift the coil without damaging it or neighboring coils. “Since it arrived,” Wood said, “the Bushman AvonTec lifter has been doing a great job.” bushmanavontec.com

Winkle Adds Magnet Model Ranges
Winkle Industries, Alliance, Ohio, has introduced a new line-up of lightweight scrap magnets developed with the latest version of the company’s proprietary computer modeling software. Winkle’s OptiMag L-Series lifting magnets for scrap recyclers now include two model ranges, the LDSA magnets, updated from the previous LSA standard, and a new ELDSA line created specifically for smaller hydraulic scrap handling machines. The new L-Series models offer increased lifting capacity with lighter weight magnets. Through the redesign and enhancement process, Winkle also reduced costs in the new line-up of L-Series magnets through improved manufacturing and material efficiencies. The LDSA and ELDSA types are both recommended for fixed and mixed loads in general duty scrap handling applications, providing a large lifting surface and reduced total weight to best utilize the crane’s load-lifting capacity. The lightweight LDSA and extra-light ELDSA models typically provide a weight saving of 4 percent to as much as 14 percent over comparable competitive magnets and come complete with heavy-duty mechanical features and deep-field coils. The new magnets are the result of an end-to-end redesign and enhancement program enabled by recent refinements to the proprietary engineering software developed by

Coordinated Wire Rope Introduces Maximizer Braided Chain Sling
Coordinated Wire Rope & Rigging, Wilmington, Calif., introduces the Maximizer braided chain sling. Proof-tested and certified to 50 long tons in a vertical basket, the sling is constructed with special T-1 custom paddles, 3/8-inch, seven-part Grade 100 alloy chain and connecting links. It is available in custom lengths. Lifting loads of 100 long tons is not an everyday occurrence in the port, but when the need arises, there must be lifting slings to meet the demand. The Maximizer was developed to meet the 100-long-ton capacity of the container crane, according to the company. Coordinated Wire Rope supplies other type slings that can meet this requirement, but the longshoremen community has confidence in the braided chain sling and does not wish to pursue other options like high performance fiber lifting slings. The “Maximizer” is constructed of seven parts of Grade 100 chain and connecting links with specially designed T-1 paddles to reach a capacity of 50 long tons per sling (100 long tons a pair) in a vertical basket. “The typical braided chain sling has been a staple lifting device in ports from coast to coast for many years,” explained Bo Kentner, Coordinated’s operations manager. “It was originally created due to a need to have a flexible, strong, but durable sling that could make many lifts removing heavy products from the holds of ships. Up to that time, braided wire rope slings were used but had several drawbacks.” Although as strong as the braided chain sling, pound for pound wire rope slings were easily kinked when basketing or choking a heavy load, said Kentner, and the wires were also very susceptible to breaking while going around corners, creating dangerous working conditions. “Chain was usually not the lifting device of choice because the sling could easily slide from under the load, causing the center of gravity to change and the load to fall. To solve this problem, the idea to use more than one chain gave rise to the thought of
July/August 2011 • industrialliftandhoist.com
using multiple chains connected to end hardware called ‘paddles’ and then interlacing the chain with wire rope to make it one complete, strong, durable sling but maintaining excellent flexibility,” said Kentner. The most common braided chain sling today is the sixpart sling made from Grade 80 alloy lifting chain attached to alloy paddles with Grade 80 connecting links, according to Kentner. This sling has a capacity of 34 tons in a vertical basket lifting configuration,” he explained. “Since two slings are used in lifting a single load, this is sufficient to safely lift most loads seen on the docks by today’s longshoremen. However, the container cranes throughout the world are reaching ever greater capacities with the newer cranes being rated at 100 long tons or greater. The increase in capacity of the crane is leading to lifting heavier and heavier loads.” coordinatedcompanies.com

Associated maintains a large inventory in its southern California and Houston, Texas, distribution centers, including shackles up to 600-metric ton capacity that are ready for immediate shipment. In addition, they have the ability to provide special items. The company recently received an order for a 500-ton master link product to be built to customer specifications. “The addition of the GN products is a perfect complement to our RopeBlock line of crane and rigging blocks, end fittings and other products,” said Bob Levy, vice president of operations at Associated Wire Rope. gnweb.com

Overhead Cranes
Equipment in Action
24-Hour Operation Demag double-girder overhead crane creates quick and gentle steel deliveries.
The crane is required to have various speeds to transport plates in the facility.
In
order to transport and handle steel sheets and plates, Blume Steel Service Ltd. has installed 20-ton Demag DR Pro wire rope hoists on a Demag double-girder overhead traveling crane. With this configuration, the company says the crane is gently handling heavy steel plates when needed but also travels fast when required. The customer also depends on a high level of reliability for the crane, which is in continuous operation 24 hours, seven days a week. The two hoists are equipped with two-speed lift, and they are mounted on a double-girder, top-running trolley. The crane is a top-running, double girder configuration utilizing a box girder. In the steel facility, the application also required that the travel motions be equipped with variable speed for ease when transporting the plates. The trolley and bridge speeds are both infinitely adjustable and can be changed as required by the operator. This allows travel to be fine tuned to correspond with each individual requirement. It also
permits adjustments to occur depending on the need for positioning or production throughput requirements. The double-girder, overhead traveling bridge crane has a total load capacity of 20 tons and can be used to the full capacity in more ways than one. Often called an “S&I” option, the operator can use the system in simultaneous mode or one hoist at a time in the independent mode. When the hoists are working together, the controls limit each 20-ton hoist to 10 tons only. When the operator chooses independent mode, the system renders the other 20ton hoist inoperable, and it only allows the use of one 20-ton hoist at a time for safety. The tandem hoists were needed to utilize Blume’s existing magnet spreader beam. The load capacity of the spreader was two times eight tons, and the configuration met the requirement. The operators are very pleased with the ease of the crane and the hoists. Continuous reliable operation has been yet another benefit.
