Roller Coasters and Their Movement by Peter Hildebrandt

There may not be any better way to learn physics in action, right before your eyes, than watching and riding a roller coaster. Roller coasters work basically through a variety of different forces, including inertial, gravitational and centripetal. Designers put all of these to work to create something thrill-seekers view as beautiful, a wonderful ride. Though the ride names, appearances and complexities keep changing the basic physics involved in these rides remains ever there in the background.


til hundreds of roller coasters in actual parks for such thrills stood waiting for customers. In the 1920s at least 2,000 roller coasters operated in the U.S. ­After a steady decline from 1930 to the end of the 1960s the 1970s and early 1980s saw a rebirth of such thrill-seeking, including tubular steel roller coasters with corkscrew designs. Even these are seeing changes as further innovations take their place. Though roller coasters seem akin to a large model railroad filled with passengers, there isn’t any engine anywhere. The linked cars move at first with the power of a pulled chain underneath which pulls them up a lift hill. Gravity takes over, momentum then follows and for the rest of the ride those two forces are doing much of the work. But the key is to build up that initial momentum as the train is pulled up to the top of the first hill or lift hill to get that first punch in the ride. ­The long running equipment running roller coasters has been a long chain or even series of chains running up the hill under the track. The looped chain winds around gears at the top and bottom of the hill with nothing more than a simple motor moving the chain. Like a chain Above and facing page: conveyor belt the mechanism Top Thrill Dragster at Cedar Point Amusement Park involves the catching of the cars by tough hinged hooks called Though it started out as a way to get chain dogs.

musement parks and roller coasters, though they are from another earlier age, don’t seem to be going away anytime soon. This may have something to do with advances in technology combined with the continued demand for the latest thrills available. In the past decade and a half such developments as hanging-train designs and catapult-launch techniques enable designers to push the thrill envelope further and further. New coasters have riders lying flat against the coaster while being shot down long spirals of track and others involve so much spinning, rotating, twisting, turning and virtual free falls that riders may agree with the assertion that this experience is akin to entering a “fourth” dimension. Precursors to today’s roller coasters were huge wooden ice slides. These were up to 70 feet high and were used by Russian thrill-seekers as long ago as the 1500s and 1600s. Sleds that ran on these tracks were made of wood or even actual blocks of ice. The speeds traveled, of course, were never known but at the end was a pile of sand to stop the riders. The French wanted to get in on the roller coaster action too. But in the warmer French climate ice slides were not feasible, ice tended to melt fairly quickly; waxed slides took their place with wheels in time being added to the sleds too. By 1817, the Russian mountains saw the first roller coaster in which a train was attached to a track. The train axle in turn also went into a carved groove right on the track. The French expanded on this concept, developing ever more convoluted track designs. These even included lay-

continued from page 8 tical metal fins beneath the train and friction comes into play to slow and finally stop the train. The basic physics of a roller coaster involves the build up of a store of potential energy as the chain pulls the train up the hill. This “energy of position” lets gravity have its way to pull the car down a longer distance than that involving the chain pulling it up the hill. Potential energy in turn is released as kinetic energy – motion energy hurtling the cars back down the hill and around the bends. Once you start cruising down that first hill, gravity takes over and all the built-up potential e­nergy changes to kinetic energy. Gravity applies a constant downward force on the cars. ­Roller coaster tracks channel this force. Tracks can be made to twist, bend, turn and slow down the car however they are designed. It is interesting how smaller hills will slow the cars but not stop them, but energy is again increased as soon as the car drops on the other side of the hill. The conversion of energy from potential to kinetic simply goes on and on as long as the designers would like it to, much to the enjoyment of park visitors. Basically this is a machine running on gravity 10

and inertia to do its work. ­At its most basic level, this is all a roller coaster is – a machine that uses gravity and inertia to send a train along a winding track. Next, we’ll look at the various sensations you feel during a roller coaster ride, what causes them and why they’re so enjoyable. Observant amusement-park visitors may notice three different types of roller coasters. Wooden roller coasters are akin to train tracks of course; but another set of wheels or a safety bar running underneath the tracks keeps the cars from careening off the tracks. Wooden coasters can be made to go upside down, but this is very difficult. In the 50s steel roller coasters came into play. Much more lightweight they led to even more advances; as with the wood track coasters their design has wheels running on the bottom the steel tubes involved to keep cars on the tracks. They can even flip the train upside down (though this is rare in modern wooden coasters). But, because the track and support structure are so cumbersome, a wooden track is fairly inflexible. This makes it difficult to construct complex twists and turns. In wooden coasters, the exhilarating motion is mainly up and down. The range of motion is greatly ex-

Wire Rope News & Sling Technology October 2013

panded in steel roller coasters. The world of roller coasters changed radically with the introduction of tubular steel tracks in the 1950s. As the name suggests, these tracks consist of a pair of long steel tubes. These tubes are supported by a sturdy, lightweight superstructure made out of slightly larger steel tubes or beams. Tubular steel coaster wheels are typically made from polyurethane or nylon. In addition to the traditional wheels that sit right on top of the steel track, the cars have wheels that run along the bottom of the tube and wheels that run along the sides. This design keeps the car securely anchored to the track, which is absolutely essential when the train runs through the coaster’s twists and turns. Riders will explain that these offer a completely different sensation – no more cars rattling over wooden tracks. The tubes are smooth and all welded together for a smooth, effortless ride. The Enchanted Forest in Salem, Oregon uses chains on their roller coaster lift hills. The chains are WH-82 style chains. Their roller coaster has two lift hills. The chains drag the cars up to the top of the hill before gravity takes over. “We do a gauge check on a regular continued on page 12

Wire rope is the unseen and unsung hero under many modern roller coasters

continued from page 10 basis,” explains Enchanted Forest’s David Rue, maintenance supervisor and ride specialist. “Typically our chains last about five years; at that point we do a full replacement of the chain and sprockets, top and bottom. This depends on what the park’s policy and requirements are as well. But that replacing of the chain at our park takes place whether the chain needs it or not.” Ninety weight gear oil is used for lubrication. Chains are obtained through a local distributor such as Motion Industries or McGuire Bearing. This roller coaster is a full-blown steel attraction that was built in 1984. Safety is their biggest concern and challenge, according to Rue. “In the winter we take down all our vehicles, do maintenance on them and on some of our large spindles we have particle testing on to determine if there has been any cracking.” Since Oregon can have quite a bit of wet weather, the vehicles at Enchanted Forest are unique to the industry. They actually have canopies which go over their riders, encapsulating them into something of a pocket to protect them from wet weather. “Though our roller coaster doesn’t have any loops in it, our park is built on a hill so our lift hills aren’t as big as some other coasters. We actually have two lift hills and there is an elevation change of 50 feet. The secondary lift hill brings riders back up to where they 12

load and unload the cars. Ground geography is on our side; our coasters aren’t that high off the ground because of the hill sides involved.” Cedar Point in Sandusky, Ohio has one of the oldest amusement-parks in the country. Ed Dangler, in their Maintenance Department explains that two of their rides, The Maverick and Wicked Twister use synchronous linear induction motors to move the trains up hills. Millennium Force and Top Thrill Dragster use a wire rope cable system to move the trains up hills, however, the two systems are vastly different. All of their other coasters at Cedar Point use lift chains. “The more traditional coasters do have the balance between kinetic and potential energy going on in their operation,” explains Dangler. “The chain pulls the train up the hill and the potential energy increase with height. When the train pulls away from the train the potential energy becomes kinetic as gravity takes over and is the force moving the train. In the cable systems or the SLIM systems energy is transferred to the train via electric motors (including SLIMs) or hydraulic powered drive systems. “Perhaps the biggest misunderstanding among visitors or the general public when it comes to how roller coasters operate involves the idea that we control the trains when they are free runcontinued from page 14

At that point our computerized controls system and our ride operators are in control.” At Cedar Point during the operating season much inspection, testing and adjustment takes place. The park also pays particular attention lubricating chains, wire ropes and other moving parts. During winter rebuilding of every single train takes place. They’re taken apart down to every nut, bolt and washer. Extension Non Destructive Testing (NDT) is preformed by a third party laboratory and testing company. There many manufacturers-prescribed inspection on a daily, weekly, monthly and annual basis. “We exceed all manufacturers requirements when testing, servicing, re-building and operating the rides,” adds Dangler. “Our two wooden roller coasters have complete track inspections daily where the entire tracks are walked by skilled trained carpenters. Daily inspections are a key factor in keeping them running. Our electronic control systems are complex with many redundant sub-systems. “For example roller coasters have


two computers monitoring not only critical functions but all functions. The monitoring systems for air pressure, speed regulation and the like have many components that may need replacement or adjustment from time to time. We rarely, if ever, have an air compressor problem or a leaking pipe but the monitoring systems occasionally might need a new pressure switch or an adjustment. “As Cedar Point’s oldest operating roller coaster, the Blue Streak has been thrilling riders for nearly 50 years. Generations of riders have traveled the wooden track down the 72-foot drop and over the half dozen “airtimefilled” hills. The classic Blue Streak is a perfect ride for kids and for adults who want to act like kids again. The nostalgic Blue Streak gave more than 780,000 rides in 2012. Riders must be at least 48 inches tall to ride the Blue Streak. However rider restraint system may not accommodate all guests of appropriate height. “The chains on our roller coasters are well-lubricated and inspected daily. We have all chains inspected by a chain manufacturer every year for wear. We even monitor the lift chains for alignment and breakage.  We use two electri-

Wire Rope News & Sling Technology October 2013

cal switches to monitor a critical function rather than one, again redundancy.” Speed trimming and stopping brakes are inspected every day and are monitored by the computer control system. Structural components are inspected on a regular basis. Trip times around the free running track are monitored on most roller coasters, this is related to velocity and is compared to engineered predicted speeds from the manufacturer. Diagnostic displays are a complex system in themselves. These diagnostic system help identify problems with field devices so repairs are made quicker. The design of the roller coaster is an important aspect of safety. Today advanced computers and programs make engineering more accurate and more detailed. “Keeping our patrons happy and coming back for more is another important part of our job,” adds Dangler. “We do look at what our guests and customer base suggest and tell us and we try to balance our inventory of rides to match the demographics of our guests. Thrill rides, family rides and rides designed and sized for children are the balance to strive for. We also strive for this type of balance in our stage shows and general atmosphere of our beautiful park.” WRN

Market Leader Delta Rigging & Tools Continues Its Growth Through Strategic Acquisitions By Jay Stringham

Delta Rigging & Tools, a company unique within the rigging industry by offering both sales and rental, is achieving remarkable success with its strategy of expanding its core business through strategic acquisitions.


elta Rigging & Tools (DR&T), one of the largest providers of both sales and rental of rigging and lifting products, tools and related services in the United States, is effectively pursuing its growth strategy through selective acquisitions. DR&T continues to evolve since its origin in 2004 with the acquisition of Industrial Hoist Services (Angleton, TX). Acquisitions were completed in 2006 of B&H Air Tools (Baton Rouge, LA), Port Rentals (New Iberia, LA) and Delta Wire Rope (Broussard, LA). In 2007 the acquisition of American Sling (Hurst, TX) was completed and the company was re-branded Delta Rigging & Tools. The company’s growth strategy continued in 2008 with the acquisitions of Coastal Wire Rope (Houma, LA), Kelly Wire Rope (Pasadena & Odessa, TX) and D&M Wire Rope (Grand Junction, CO). That same year, Austin Ventures acquired DR&T. In 2011 Grizzly Wire Rope & Chain (Williston, ND) was acquired and a branch opened in Victoria, TX. Working closely with Austin, Texas based private equity group, Austin Ventures, DR&T has executed an effective strategy of acquiring and inte-

grating a number of high-performing regional market leaders to create an industry-leading platform. The company serves both domestic and international customers through 18 sales, service & distribution facilities. Mitch Hausman joined DR&T as President and Chief Operating Officer in December 2011 and became CEO in December 2012. Hausman had a successful 30-year career at Southwest Wire Rope LP, where for 18 years he served as President and CEO. His career began in 1979 with WireCo World

Group in St. Joseph, MO. 2013 has been an aggressive growth year for DR&T. In June the company enhanced its position in the maritime and offshore sectors with its acquisition of Morgan City Rentals, a leading provider of offshore rental equipment and rigging products in the Gulf of Mexico. “Morgan City Rentals was an ideal fit for us,” explains Hausman, “because of the quality and breadth of its products and services. This acquisition met one of our key strategic initiatives: to increase our offshore rental and rigging business and to go deeper into the offshore oil and gas drilling and production markets.” Established in 1970 and located in Morgan City, LA, with additional locations in Golden Meadow, LA and Broussard, LA, Morgan City Rentals has a wide range of offshore rental equipment, wire rope, rigging hardware, sling fabrication, and compliance load testing for the offshore oil and gas industry. Joe Sanford, Jr., former President & Owner of Morgan City Rentals, adds, “I am very pleased to have found a partner like DR&T that provides such a compelling fit for our employees and customers. We are excited to join forces with the talented management team of DR&T. Both Morgan City Rentals and DR&T are well-known companies managed by executives with decades of experience in the rental equipment and rigging business. We now have the industries’ most extensive fleet of pipe slings, hoists, winches, compressors, pumps and related rigging equipment.” Combined with DR&T’s existing operations in Broussard, LA and Houma, LA, the acquisition established DR&T as the leading offshore rental and rigging company in the

Delta Rigging & Tools’ corporate offices are based in Pearland, Texas and overall DR&T consist of five divisions and 18 sales and service locations. Locations include: Angleton, TX; Baton Rouge, LA; Sulphur, LA; Broussard, LA; Houma, LA; Port of Fourchon, LA; Odessa, TX; Pasadena, TX; Victoria, TX; Grand Junction, CO; Williston, ND; Hurst, TX; Tulsa, OK; and Wichita, KS. Morgan City Rentals has locations in Morgan City, LA; Golden Meadow, LA; and Broussard, LA

Gulf of Mexico market. The Morgan City Rentals acquisition solidifies DR&T’s position in the growing Gulf of Mexico market. As a testament to the strength of the Morgan City Rentals brand and its leadership team, it will continue to operate as “Morgan City Rentals – A Delta Rigging & Tools Company.” In August of this year, DR&T acquired Holloway Wire Rope, a supplier of wire rope, below-the-hook lifting devices and rigging supplies. Headquartered in Tulsa, OK, with a second location in Wichita, KS, Holloway Wire Rope expanded DR&T’s footprint into the Oklahoma oil and gas fields, along with broadening its reach into the Midwest markets. “Holloway Wire Rope offered us a geographical advantage to expand our footprint,” says Hausman. “Adding a well-established business with great customer and vendor relationships was a strong strategic move for us, ensuring we provide a high level of service to

our existing and new customers working in the Midwest.” Holloway Wire Rope adds a rich history to the legacy being built by DR&T. Holloway Wire Rope recently celebrated its 72 anniversary in the industry and it is one of the earliest established wire rope and rigging companies in the United States. Curt Tuggle, former President &

Owner of Holloway Wire Rope, has joined the DR&T management team, serving as General Manager of the Tulsa and Wichita operations. With approximately 500 employees, DR&T is committed to its four key values: Safety, Service, Quality and Value. Key markets for Delta Rigging & Tools include: •  Energy -Land-based -Offshore -Refining & Petro-chemical •  Construction •  Marine •  Transportation •  Industrial/Manufacturing/ Engineering •  Mining •  Government Strategically located at the InterMoor facility at the Port of Fourchon, Louisiana, DR&T offers costeffective solutions to the Gulf Coast’s high capacity load testing needs.

In Preparing for Earthquakes, Wire Rope Can Be Part of the Solution By Peter Hildebrandt

Some of the most populated cities in earth also happen to be in very seismically active areas. Such cities as Tokyo, San Francisco and Istanbul – though all meet that geological criteria – also will most likely have vastly different things happen to their populations in the event of a quake. The reason for that comes down, quite simply, to building and infrastructure design, engineering and reinforcement.


s might be imagined, those places where adequate forethought has been given in the building of area structures and energy or water supply systems typically can experience much less major catastrophic damage than in areas where proper engineering and reinforcement are non-existent. Ask anyone how damage occurs from an earthquake and you should get the obvious answer, through the shaking of the ground.

Ground shaking, however is perhaps much more complicated than we might imagine. In the famous Alaska earthquake of 1964, earth scientists noted the wide variations in damaged based largely on the area soils in various affected areas. Today’s engineers must take soil structure and composition and many other factors into account when designing structures; many factors and complex phenomena come into play during an earthquake.

Structures in an area where an earthquake strikes will sway as the wave-like energy beneath them is released. This goes for buildings shaking and swaying in the area. It might make more sense to think that a skyscraper would be more dangerous than a smaller building, but in fact, the opposite is frequently true. The taller a structure, the more flexible it is and the more flexible it is, the less energy is required to continued on page 22

The Arthur Ravenel Jr. Bridge is an eight-lane, cable-stayed suspension bridge connecting downtown Charleston with nearby Mount Pleasant over the Cooper River. The main span is 1,546 feet long (the 3rd longest cable-stay in the Western hemisphere), with 128 individual cables connected to two 575-foot high diamond shaped towers able to withstand wind gusts up to three-hundred miles-an-hour, as well as up to a 7.4 magnitude earthquake.

continued from page 20 keep it from toppling or collapsing during an earthquake. Standing riders on a bus or subway car have an easier time remaining standing if they flex their body and flow with bumps and rather than remain rigid and unbending. This stiffness is present in shorter structures such as a three-story apartment building, often thought to be more defenseless to earthquake damage than a 30-story skyscraper. Structural

engineers must design the support elements of shorter buildings to withstand greater acceleration than those of taller building. Construction material used on the building also determine its strength – with flexibility being a critical component. Wood and steel have more give than stucco, concrete which is not reinforced or masonry, and they are favored materials for building in fault zones. All skyscrapers need reinforcement to withstand strong forces

The Loma Prieta earthquake struck the San Francisco Bay Area of California on October 17, 1989. Caused by a slip along the San Andreas Fault, the quake lasted 10 to 15 seconds and measured 6.9 on both the moment magnitude scale (surface-wave magnitude 7.1) and on the open-ended Richter Scale. The quake killed 63 people throughout Northern California, injured 3,757 and left some 3,000–12,000 people homeless.

from high winds, but with earthquakes come extra considerations. Buildings must absorb the wave energy throughout the entire height of the building. Walls and floors, if built right may be able to in turn transfer the shaking energy downward through the building and back to the ground. Even joints between supporting components of the structure may be reinforced to endure being bent or deformed and earthquake. San Francisco’s distinctive TransAmerica pyramid has incorporated an easily seen seismic abatement feature in the form of the truss. In addition to the truss, a notable network of diagonal trusses starting at the wide base and narrowing at the top of the building makes the structure even more stable. Perhaps the most visually recognizable seismic safety feature of tall buildings is the truss. The TransAmerica pyramid in San Francisco is famous for its architecture: a wide base that narrows as it goes up increases the building’s stability. A network of diagonal trusses at its base supports the building against both horizontal and vertical forces. Buildings in earthquake zones may also be strengthened against the forces involved with something called base isolators. Just as the term says, these devices isolate the building from the forces to which the structure is being subjected. They mostly come in two forms, a giant hockey puck-type damper, squishing and deforming as the building above shakes and rocks. Another type consists of two horizontal surfaces, plates which are made frictionless in order to slide past each other. With the building on the top plates, the bottom plates rest on the ground. The “moving” earth and the building inertia slide relative to each otherback and forth beneath the plates. In the State with the Most Earthquakes The most recent cable-stay bridges built in Alaska were built in around 1976. (The so-called “Bridge to Nowhere” which became an issue in the 2008 Presidential Election Campaign never was built, even for the projected cost of $398 million dollars; funding for the project has continued as of March, 2011.)

continued from page 22 for the bridges, the Alaska Department of transportation has done that. They have not, however changed anything in the cables other than performed detailed inspections. It’s always been bearings, seat widths as well as restrainers that have been refitted – not the cables. “I’m assuming they’ve been analyzed for stress,” explains Loren Gehring, PE Bridge Engineer for Alaska Department of Transportation and Public Facilities, “They seem to be adequate for the capacities that they are handling. We do use cable for restrainers for retrofit of some multiple simple span bridges, primarily where liquefaction is a concern. For bearing seat width we would typically just extend the seat to whatever is required.” Also, cables would be used for liquefaction problems as a retrofit measure since the pier or the support walks due to this condition, according to Gehring. There is really nothing that can be done to retrofit other than to try to tie it to the bridge superstructure with cable. That is a function of cables; steel rods are able to be used as well, depending on whether or not the rods can be anchored somehow. Since the devastating Anchorage


earthquake in 1964, earthquakes in Koo Bay, Northridge, Turkey and throughout the world, once they are studied and evaluated, means that design methodology changed considerably in the last 30 to 40 years and with that comes a push for structural support changes. “It’s unfortunate, but the engineering field learns from disaster that have happened, finding out what works and doesn’t work constructionwise and from designs already in use,” says Gehring. “We as engineers and designers have design codes to follow. If you understand the principles of the analysis and realize that we are using a displacement-based approach for earthquakes and not a force-based approach, it’s clear that we’re not trying to resist forces much. We are simply trying to allow displacement so the bridge is going to flex and move when the event occurs. “Our designs are accommodating the displacements that are anticipated for a design event per AASHTO which dictates using a 7% probability of exceedance in 75. I’ve never been to Turkey and looked at the bridges. But I’ve seen pictures and I understand that the design codes are based on what they’ve

learned in real life situations as well as based on what they’ve studied in labs.” Codes to get Insure Proper Protection “We don’t make things specifically for earthquake service,” explains Tom Secules, Wire Rope Works project manager, structural products. “We make things according to standard specifications or sometimes special specifications. Those people who are designing the application will choose the standards that they’re going to be using such as ASPM 8603; there is one application in particular that I am familiar with and that uses 8603 seven-eighths inch rope for restraint or bridges, typically from falling off their tillers in case of an earthquake, restraining the motion of the bridge.” The percentage of work done in that area of earthquake protection wire rope and fittings at Wire Rope Works is quite small, according to Secules. “During the 1989 earthquake in the San Francisco Bay Area I’m not aware any bridges that were affected that had anything to do with materials that we make, suspension bridges in particular. They survived that quake pretty well. continued on page 26

continued from page 24 “However the Oakland Bay Bridge, particularly the stretch between Yerba Buena Island and Oakland – that’s what’s being replaced right now. During the quake the upper level dropped onto the lower deck.” That is something that is trying to be avoided in another earthquake. The older bridge was a double decked cantilever truss bridge; it is now going to a single tower, self-anchored suspension bridge – all on one level to avoid the events of the 1989 bridge failure. From tonnage that Wire Rope Works makes and dollars earned from that segment, the largest portion of their work and sales comes from both underground and surface mining industry, not earthquake protection components. “The bottom line is that we make wire ropes and assemblies as well as related equipment but we don’t design specifically for anything having to do with earthquakes per se,” says Secules. “The people who need a product for earthquake protection look at what we make and use that in their application.” Earthquakes have a tendency to stretch wire rope when they occur, therefore pre-stretching is essential on seismic cable. Sway bracing is cru-

cial as is the fact that the permanent end fittings have the capability of the wire rope cable itself. Building damage occurring due to the large recent earthquakes highlighted the necessity of rehabilitation of existing structures in order for them to withstand seismic loads. Flexibility inherent in a Moment Resistant Frame (MRF) system may result in large drift and structural and nonstructural damage necessitating costly post-earthquake retrofits. Though an MRF system has a large ductility capacity, an MRF also requires large columns for keeping its drifts in the permissible boundary outlined by seismic codes. A few companies around the country manufacture and sell pre-stretched, color-coded, break strength certified, seismic wire rope/cable™ Bracing for use in satisfying the requirements of the Laws, Codes, Standards and Specifications for Earthquake Resistance of Architectural, Mechanical and Electrical Components and Systems. These braces are Underwriters Laboratories Listed® for use in satisfying the requirements of NFPA-13 for all pipe sizes and are pending OSHDP Pre-Approval (California Office of

Statewide Health Planning and Development Fixed Equipment Anchorage Pre-Approval) for hospitals and other State regulated facilities. Further, these braces have been pre-engineered for use in satisfying the earthquake bracing of all the Model Codes and Standards for all non-structural building components and systems. We’ve come a long long way in our understanding of both earthquakes and what needs to be done to insure the safety of populations living in earthquake zones. The finality of the damage, death and destruction in the wake of an earthquake may lead people to fall into the trap of thinking there is finality to this event. But earthquakes are dynamic, ever-occurring events as the crust of the earth itself is continually, relentlessly being destroyed, recycled and rebuilt. Engineers and earth scientists can explain to us what the latest state-ofthe-arts technology is for protection and what needs to be incorporated into buildings and infrastructure to make it as safe as humanly possible. Whether planners or local politicians choose to spend the money required for such protective construction beforehand is another issue altogether. WRN

Are You a Great Manager?

Test Yourself in These 10 Vital Areas By Phillip M. Perry

Managers with great “people skills” are more successful at motivating employees and building business profits. How can you improve your own techniques for obtaining a high level of employee performance? One way is to take this quiz. The answers will help you assess your strengths and identify areas needing improvement.


re you a great manager? Tough question. While you may be experienced at assessing the performance of your employees, you probably spend less time judging your own. Your business profits, though, depend on how well you carry out your mission. That means exhibiting more than technical savvy: You must also fine tune the vital “people skills” that motivate your staff to over-achieve and generate more sales. Why not run your own self-assessment? Test yourself with the following quiz. Rate your performance from one

to 10 (higher being better) on each of these 10 questions. Total your score. How close do you come to 100? 1) Do you challenge employees to set specific performance goals? “Do better every year.” That’s a great motto for every employee. Too often, though, the tendency is less ambitious: Coast along. Settle for a performance that’s good but not great. “Employees tend to float to the status quo,” says John Tschohl, President of Service Quality Institute, Minneapolis. (www.customer-service. com), and author of Moving Up. “The

problem is that very few have any well-defined goals.” It’s too easy to settle for hazy goals such as ‘be a better sales person’ or ‘increase technical skills.’ “That’s not good enough,” says Tschohl. “Hazy goals produce hazy results.” Solution? Work with employees to establish measurable objectives. “Make sure the goals are specific,” says Tschohl. Here’s an example: “Make 10 sales calls per day” is better than the more general “Make more sales calls.” Bonus tip: Set target dates for goals continued on page 30

continued from page 28 and assess results at follow-up performance reviews. 2) Do you coach employees to rebound from performance shortfalls? Saying’s one thing. Doing’s another. The most dependable employee can miss an ambitious performance goal. Maybe the bar was set too high. More likely the person needs to take a different approach to the challenge. That’s where you come in. Monitor the employee’s work practices and suggest new ways to reach performance goals. Then reset the target date and stay in communication. But you need to do more: You must also help pump up the employee’s selfesteem. “Employees need a lot of support,” says Tschohl. “Most have a lot of self-doubt and personal problems. So you want to be nurturing people to do a better job. And when you see people doing great things you should give them recognition.” Bonus tip: When recognizing an employee’s performance don’t just state a general remark such as “good job.” Highlight how well the individual performed specific work activities. 3) Do you communicate your

priorities and directions clearly? To be followed and respected you need to be understood. Make clear communications your goal. Express what you want from your employees in easily understood statements that can be translated into workplace expectations. Clarity of communication will help employees stay on track toward achieving their goals. “Employees tend to become unfocussed,” says Tschohl. “They get distracted and concentrate on one thing instead of another. A good manager will stay on top of people, coaching and reinforcing.” Bonus tip: Ask you employees for feedback: Are they confused by anything you have said? Can you restate anything more clearly? 4) Do you encourage your employees to contribute new ideas? Sometimes owners and managers think they can “do it all” and fail to take advantage of—or even become aware of—surrounding talent. Other times they are reluctant to reach out, frightened of giving up power or too focused on their ego to tap the skills latent in others. Blocking the skills and ideas of employees can lead to the loss of the best talent. “Creative, ambitious employees

will leave the company to find other positions,” says Richard Avdoian, an employee development consultant in Metropolitan St. Louis. ( “They want to enhance their own skills and if they are not encouraged to do that they will seek other employment.” Great managers pursue the gold hidden in every employee, says Avdoian. “Tapping the gifts and talents of the employees can make any business flourish.” Bonus tip: Establish an awards system for the best ideas that contribute to business profit. 5) Do you take a personal interest in your employees? Your employees are human beings with varied talents and needs, not cogs in the profit machine. Taking a genuine interest in their lives will foster their loyalty and pay rich dividends. “Discover the hidden talents of your employees and use them,” says Avdoian. “Employees who realize they are valued as people will be vested in giving back to the company. Even if those individuals need to leave some day because there is no spot for them to be promoted, they will be ambassadors for your business.” continued on page 32

continued from page 30 Bonus tip: In job interviews ask questions that uncover hidden talents—not just the specific skills required for available positions. 6) Do you delegate well? Some managers are afraid of giving up power if they delegate. But good delegation is a way of leveraging the talents of others to enhance a manager’s reputation for performance. “Delegating is not about giving away your responsibilities,” says Avdoian. “It’s about putting together all the piec-

es of the management puzzle. The bottom line is that the person at the helm needs to direct everyone.” Bonus tip: Keep asking, “Who can I give this task to who is talented and who will help our team succeed?” 7) Do you resolve conflicts in a productive way? “Many leaders try to resolve conflicts in a way that appeases everyone,” says Will Bowen, a productivity consultant in Kansas City, Mo. ( “But if we try to please everyone we end up pleasing no one.”

Of course, when tackling a workplace problem it’s fine to pursue an optimal solution. But don’t let the search become an endless journey. Making a controversial call, though, can raise hackles. How can you keep the peace when establishing a position less attractive than what people want? “Make sure everyone knows that a lot of thought went into your decision,” says Bowen. “It was made for the highest good of the organization.” Bonus tip: Announce controversial decisions at meetings scheduled for that purpose. Explain the reasoning that went behind your decisions. 8) Do you behave in a professional way at work? “More than anything, people judge leaders by their bearing,” says Bowen. “Employees need someone like the captain of a ship, moving them through rough seas with solid bearing. They need to feel that person has the emotional maturity to warrant being their leader.” Conversely, people tend to feel insecure with a manager who is easily rattled, says Bowen. Leaders could do worse than recall three words drilled into people learning to fly a plane: aviate, navigate and communicate. Says Bowen: “First you aviate by flying the plane; then you navigate by figuring out your direction; finally you communicate by telling others where you are going.” Just don’t get the priorities mixed. “What most people do is start by communicating, running off at the mouth,” says Bowen. “Remember that first you need to fly the plane, doing the things that are most important. Then decide on the direction you want your organization to go. At that point you are prepared to communicate your vision so people will follow.” Bonus tip: Take a break if you encounter a situation you can’t handle with equanimity. Get away from other people for a while, giving yourself time to yourself before you attempt to lead. 9) Do you listen well? People want to be heard. When they see that you are listening they feel empowered and will invest in your decisions. Too often managers do anything but. “So many times we only seem to be listening to someone,” says Bowen. “Our mouths are shut and we are looking at the other person, but inside we are preparing what we will say next and we are judging what the other person says.” Be willing to learn. Then you will listen closely. “Listening is an atticontinued on page 34

If you are unwilling to be changed you are not listening.” Bonus tip: Communicate your willingness to hear by responding to employee statements with productive questions. 10) Do you inspire your employees? Your employees need to be skilled and knowledgeable. But they need to acquire another characteristic if your business is to outperform your competition: Enthusiasm. Enthusiastic employees sell more, please more customers and dream up

better ways to boost profits. But just what makes employees enthusiastic? That’s where you come in. “Most employees have a lot of selfdoubt,” says Tschohl. “You have to make them feel good about themselves.” Part of that is being specific about their achievements. “Use positive feedback to inspire people,” says Tschohl. “Here’s an example of what you can say: ‘You have more ability than anyone else in this organization. You have more drive, more energy. I am counting on you.’” Bonus tip: Inspire people by communicating how they will be integral parts of your business plan for the coming year. People skills Guidance.

Preliminary steel imports increase1% in July

Import market share 22% in July Based on preliminary Census Bureau data, the American Iron and Steel Institute (AISI) reported that the U.S. imported a total of 2,475,000 net tons (NT) of steel in July, including 1,956,000 net tons (NT) of finished steel (up 0.6% and down 0.9%, respectively, vs. June final data). Year-todate (YTD) total and finished steel imports are 18,207,000 and 14,325,000 net tons (NT), respectively, down 11% and 10% vs. 2012. Annualized total in finished steel imorts in 2013 would be 31.2 and 24.6 million NT, down 7% and 5% respectively vs. 2012. Finished steel import market share was an estimated 22% in July and is estimated 23% YTD. Key finished steel products with a significant import increase in July 2013 compared to June are wire rods (up 52%), hot rolled bars (up 23%) and hot rolled sheets (up 19%). In July, the largest volumes of finished steel imports from offshore were all from Asia and Europe. They were from South Korea (263,000 NT, p 10% vs. June final), China (176,000 NT, up 14%), Japan (148,000 NT, up 12%), Germany (91,000 NT, down 15%) and Taiwan (73,000 NT, up 35%). For seven months of 2013, the largest offshore suppliers were South Korea (2,020,000 NT, down 10%), Japan (1,106,000 NT, down 8%), China (1,075,000 NT, up 16%), Turkey (798,000 NT, down 15%) and Germany (646,000 NT, down 11%). On this page are charts on estimate steel import market share in recent months and on finished steel imports from offshore by country.

June steel shipments down 3.0 percent from May

Down 5.4 percent from prior year The American Iron and Steel Institute (AISI) reported that for the month of June 2013, U.S. steel mills shipped 7,806,319 net tons, a 3 percent decrease from the 8,047,245 net tons shipped in the previous month, May 2013, and a 2.6 percent decrease from the 8,016,834 net tons shipped in June 2012. Shipments year-to-date in 2013 are 47,401,474 net tons, a 5.4 percent decrease vs. 2012 shipments of 50,117,104 net tons for six months. A comparison of June shipments to the previous month of May shows 36

the following changes: hot rolled sheet, down 2 percent, hot dipped galvanized sheets and strip, down 5 percent and cold rolled sheet, down 5 percent.

AISI comments on U.S. Steel leadership changes

Thomas J. Gibson, President and CEO of the American Iron and Steel Institute (AISI), had the following statement regarding the election of Mario Longhi as CEO of U.S. Steel and the retirement of current CEO John Surma expected at the end of the year: “The steel industry in general, and AISI in particular, will forever be indebted to John Surma for his passion, wisdom, commitment and leadership over the past decade as CEO of U.S. Steel. John has gone to great lengths to ensure our industry is at the forefront of advocacy on behalf of the manufacturing sector in America and the world. John’s thoughtful and strategic counsel provided AISI, and the

AISI applauds ITC imports vote

The American Iron and Steel Institute (AISI) applauded affirmative preliminary injury vote by the International Trade Commission (ITC), which allows the antidumping and countervailing duty investigations on certain Oil Country Tubular Goods (OCTG) from India, Philippines, Saudi Arabia, South Korea, Taiwan, Thailand, Turkey, Ukraine and Vietnam to move forward. Thomas J. Gibson, President and CEO of AISI, said, “We are very pleased that the ITC has taken this significant first step in making a preliminary determination that these imports are causing material injury to the domestic steel industry. The U.S. laws against unfair trade exist to counter marketdistorting practices – like dumping and subsidies -- and to restore conditions of fair trade. U.S. companies and their workers deserve to have a fair shake, and we applaud the vote as an important move towards providing U.S. steel producers relief from unfairly traded OCTG imports.” Gibson said that imports from these countries have surged by 111 percent

Wire Rope News & Sling Technology October 2013

in the past few years. He noted that 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.

Lift-It Manufacturing celebrates 34 years of service to the sling and rigging community

The Lift-It family celebrated 34 years of successful operation on September 3, 2013 with a company lunch and presentations done by Mike Gelskey, Sr. and Mike Gelskey, Jr. 1979 was an interesting year to start a business. Domestically, gas rationing and 19% prime interest rates prevailed. Internationally, U.S. embassy employees were being held hostage. M. Gelskey, Sr. was 24, and set up vendors and arranged for financing through private sources (at prime plus 2). Distribution was managed by Ken Keeble and Darrell Dudley of West Rep Enterprises. Ed Martensen, former owner of Martensen Enterprises was also one of Gelskey’s partners in the beginning. Gelskey, Sr. comments, “I was fairly occupied with purchasing equipment and lining up suppliers and

in my spare time built tables and wrote our first catalog, all 24 pages of it. Failure was not an option and the hours were unrelenting”. In 1981 Gelskey realized that the most effective way to promote the proper use of slings and rigging was to present training classes that ranged from one to four hours. Thirty-two years later those initial training sessions have evolved into single and multiple day presentations done on site or at the Lift-It Learning Center in Pomona, CA. Mike Gelskey, Jr. comments, “It’s hard to believe that when I was two I was standing on the freshly varnished tables in our first shop as the first load of webbing was put away and now have the honor of working with father and Wolfgang Keil, two of the original five persons who started Lift-It. Edna Quintero and Dorothy Smith are both alive and in their eighties. Dave Barthule, the man who taught my father how to sew passed away in 2003”. The five have now grown to fifty and in both the shop and office there are three generations working to further grow the business. Gelskey, Sr. remarks, “We’re a small business, but for

Spider provides suspended scaffolding, fall protection & training for Penterra Plaza, Denver

Spider, a division of SafeWorks, LLC, provided a complete suspended access solution to general contractor Reconstruction Experts, Inc. for inspection and repair work on the Penterra Plaza in Denver, CO. This 280-ft tall, multi-terraced commercial and residential building required inspection of every weep hole and brick tuck pointing location of the exterior façade, leak and pressure tests on every window fitting, and corrective glazing work on failed windows. Over 750 linear feet of SpiderRail™, Spider’s new temporary guardrail system, was used to provide OSHA-compliant fall protection along the edges of the building. Seven modular platforms ranging in length from 20-35 ft and powered by Zmac® hoists, twenty davits, and custom engineered davit adapters provided access for the contractors to complete their inspection and repair work to the windows & façade. Finally, a 170T hydraulic crane was used to load the equipment onto the building. Spider was involved in all of the safety planning for this project and provided Competent Person Training for all of the mason workers, glaziers and general contractors utilizing the equipment. “As a first time customer of Spider, I have nothing but positive things to say about the equipment and service they are providing for the Penterra Plaza project,” states Jake Marshall, Project Manager with Reconstruction Experts, Inc. “Whenever we are faced with challenges, Spider’s Denver team personally takes action and delivers a safe and timely solution. We are especially impressed with their plan to utilize a

crane service to load the equipment onto the structure, since transporting it through the building would have been disruptive to the building’s occupants. Not only did this improve our efficiency, it reassured the building owners that their concerns were our top priority.” Spider was the only local swing stage company that could provide the high volume of rental equipment, custom fabrication and engineering, and extensive training required for Penterra Plaza.

solution, including swing stages, fall protection and training, for installation of panels on the façade of the 400ft tall Colorado State Bank Building in downtown Denver, CO. Under the direction of general contractor Swinerton Builders, Spider supplied subcontractor GEN3 with nine u-shaped swing stages powered by Zmac/1000® traction hoists to ac-

cess the columns of the structure. In addition, seven standard modular platforms ranging in length from 15 ft to 45 ft and also powered by the workhorse Zmac/1000®s are increasing efficiency by feeding materials to the ushaped stages. Safety line, rope grabs and termination plates from Spider’s trusted line of fall protection solutions are also in place throughout the project. Spider provided Competent Person Training for all of the equipment operators from GEN3 and Swinerton Builders and is making regular site visits to ensure safety compliance. “Spider’s cooperation and knowledge is second to none, and as the superintendent for the 27-story reclad of the Colorado State Bank building, that makes them first in line when it’s 44

Made

with Dyneema® fiber, the slings were used last week to cradle the spire, and carefully lift it into place at the peak of the building. The addition of the magnificent 408-foot silver spire brought Freedom Tower to its full height, a symbolic 1,776 feet, making Freedom Tower the tallest building in the Western Hemisphere.

They fuse state-of-the-art materials with proprietary technology to create a product of unprecedented safety and performance. As a supplier to Slingmax and their worldwide dealers, DSM Dyneema is proud of their partners’ role in this historic and patriotic moment for the United States of America. DSM Dyneema thanks Slingmax for their trust in using Dyneema® in these state-of-the-art roundslings. “We are honored to have been a part of the construction of One World Trade Center, an iconic symbol of American strength and resilience, through our partners Slingmax and ASC Industries,” said Christian Widdershoven, Vice President Marketing & Sales,

DSM Dyneema Business Group. “After the terrible events of 9/11, DSM Dyneema supplied fiber and sheet materials to its customers for the manufacture of ballistic protection products for troops, homeland security and other emergency responders. Today, we are immensely pleased to have played a role in the construction of a symbol of triumph over those dark events, a historic moment for America and the world.” In addition to the lightweight strength of Dyneema® fiber, unsurpassed abrasion resistance and low stretch properties, Slingmax roundslings offer the Check-Fast® Inspection System that warns users of overload conditions before damage occurs, fiber optic inspection to detect early warning signs of damage, redundant protection delivered by two independently functioning slings in one, unique length tolerances of less than one percent, and unmatched repairability. More than 90 percent of damaged TPXC slings can be repaired. All these features, combined with Slingmax’s role in crowning the Freedom Tower give new meaning to the brand promise of Dyneema®: “With you when it matters.” continued on next page

pewag to produce chain in America

Insulating link manufacturers work to complete ASTM version On September 5, 2013 UL (“Underwriters Laboratories”) announced the withdrawal of its Standard for Crane Insulators, UL2737. No immediate reason was given for the withdrawal of UL2737. Miller Lifting Products and H.J. Hirtzer & Associates, another USbased insulating link manufacturer, had voiced concern that UL2737 was highly reflective of the unique design features of a single manufacturer’s product and that it was a new standard, developed without the involvement of peer manufacturers. Currently, an ASTM committee, including the three manufacturers who are active in the US market for crane insulators, and a number of independent experts, is in the final stage of developing a definitive test standard for Insulating Lifting Links for Load Lifting Equipment Working near Energized Power Lines. It is intended that this consensus-based ASTM standard will be applied by an OSHAapproved NRTL (Nationally Recognized Testing Laboratory) to qualify

insulating links for use in compliance with recent changes to the OSHA crane safety standard concerning cranes operating near power lines. “We are hopeful that the construction industry will soon have a test standard which can used by an NRTL to qualify these important safety devices for the benefit of workers involved in crane operations near power lines”, said Paul Jankovic, president of Miller Lifting Products. Accidental contacts with overhead power lines causing electrocution are the main cause of construction site deaths involving crane operations. Use of an insulating link is one of a number of actions employers must consider in order to comply with recently updated OSHA crane safety regulations addressing power line safety in construction. Miller Lifting Products, founded in 1935, is a manufacturer of lifting accessories primarily for use with cranes and hoists in the construction, industrial, offshore and energy sectors and has produced insulating links for a wide range of industrial applications for over four decades.

Newly-developed recommended test method for sling and tie down webbing released by WSTDA

BEL AIR, Maryland (September 25, 2013) - The Web Sling & Tie Down Association (WSTDA) is pleased to announce the recent publication of its newly-developed Strength & Elongation Recommended Test Method for Sling & Tie Down Webbing (WSTDA-TM-1)©. The recommended test method ap-

plies to the tensile strength and elongation test method for sling and tie down webbing, and recommends the equipment and method for testing widths up through twelve inches. This recommended test method is modeled after Federal Test Method Standard No. 191A, Method 4108. The original federal standard was inactivated and is no longer updated or revised by the U.S. government. Other standards such as ASTM describe testing methods for tensile strength and elongation but are limited in the width

and tensile strength that can be tested. The Web Sling & Tie Down Association (WSTDA) is a non-profit, technical association dedicated to the development and promotion of voluntary recommended standards, test methods, and associated reference materials. Members of the WSTDA include manufacturers and suppliers of synthetic web slings and tie downs, polyester roundslings, synthetic webbing, fibers, thread and related components.

Inventor’s Corner By William Fischer

Welcome to the autumn edition of Inventor’s Corner, and thank you as always for your interest. With all of the extreme weather events that have been taking place and that will surely rear up during this hurricane season, the industries that rely on the wire rope industry will be as busy as ever. While it does mean a good deal of construction projects, we should never forget those who bear the brunt of these most unfortunate circumstances. Our hearts go out to those currently suffering from the terrible flooding in Colorado, in addition to all of the people dealing with other such catastrophic events. Cable assembly with anchor Pat. 8,181,437 U.S. class 57/22 Int. class D01H 15/00 Inventor: David Malcolm Glennie, Singapore, SG., Lew Kah Hoo, Singapore, SG. Assignee: Franklin Offshore International Pte. Ltd., Singapore, SG. A cable assembly comprises a cable having a main body, strands, a tail and a first cable end, an anchor, and a sleeve having a bore, a first end and a second end. The first end is positioned generally adjacent the anchor, the second end is positioned remote from the anchor, and the cable end is positioned in the bore. A cured adhesive is positioned in the bore, binding the sleeve to the cable, along with a rope insert which is positioned at least partially in the bore, wherein the cured adhesive holds at least one rope insert in a fixed position with respect to the sleeve. Turning now to the drawings, figure 1 shows a side view of a preferred embodiment of the cable assembly 10. The cable assembly 10 includes a cable 12 having a main body 14. Preferably the cable 12 comprises a core rope and outer ropes 19. Each rope preferably comprises a series of strands 16. The construction of the core rope and the outer ropes 19 is preferably in accordance with the standards specified in ISO 10425:2003 API-9A. Each of the strands 16 can comprise steel or another suitable high strength material. Preferably the cable assembly 10 has an anchor 25. The anchor 25 can be formed as a flemish eye 24. Rope 19 of the cable is split into portions at a tail 20 and wrapped over an opposite portion of the rope. The portions are recombined with the main body 14 at a cable end 22 at a sleeve 30. Optionally an end cap 70 may be provided which is useful as an antifouling member during use. In a similar manner, the anchor can also comprise a second anchor 125 formed as a second flemish eye 124 at a second tail 120 and may be closed off at a second end 122 of the cable 12 using a second sleeve 130 and an optional second end cap 170.

eye 24 is formed by dividing strands of the cable at the tail 20, and wrapping or laying the strands over each other. A first end 22 of the cable is secured around the main body of the cable inside a bore 32 of the sleeve 30. Preferably the sleeve 30 circumferentially surrounds a portion of the main body 14 of the cable 12 and a portion of the tail 20. The sleeve 30 has a first end 34 generally adjacent the anchor 25 and a second end 36 positioned more remote from the anchor 25. The tail 20 is preferably distributed or wrapped evenly around the main body 14 of the cable to ensure a uniform load distribution. The sleeve 30 and adhesive 40 cooperate to lock the strands 16 of the cable 12 in place. A positioning ring 60 may be provided which is preferably positioned in the bore 32. The ring 60 may extend circumferentially around the cable 12. The ring 60 acts as an alignment agent, centering the cable within the bore 32. The ring 60 also allows the tail and main body 14 to set in the adhesive in a controlled manner during assembly. Preferably the ring is positioned near a second end 36 of the sleeve 30. Both the sleeve and the positioning ring may be made of steel or other suitable high strength material. The adhesive 40 which is used to help hold the flemish eye 24 in place is preferably a composite resin or a thermosetting resin. A suitable example of an acceptable resin is sold under the name Maklock. During assembly, the adhesive is introduced into the sleeve after the flemish eye is formed and the sleeve is fitted around the cable. The second end 36 of the sleeve is preferably sealed using plasticine or a similar material to prevent leakage. As a further advantageous step, a quantity of the resin, such as between 5 and 10% of the total volume, is preferably mixed and poured into the sleeve after the sleeve is sealed. The adhesive is preferably allowed to harden before a main pour is made to complete and strengthen the seal ensuring that there will be no leakage of the main pour. Once the resin is mixed to a preferred consistency, the resin should be poured immediately into the sleeve to ensure good penetration into interstices (gaps) of continued on next page

ble assembly when in use. In accordance with a highly advantageous feature, rope inserts 50 are positioned within the bore 32 of the sleeve 30. The rope inserts 50 preferably comprise a short length of a cable similar to the material used for cable 12. However, the rope inserts 50 may use strands smaller in diameter than the strands 16 of cable 12. The rope inserts are shown in figure 2 as positioned within the bore circumferentially around the cable 12 and can preferably have a stem 52 and broom 54. Most preferably, at least one rope insert extends partially out of the adhesive and even out of the bore of the sleeve. That is, the broom 54 is exposed by a small amount (for example 1 to 2 mm) above the adhesive. The broom 54 can comprise part of the rope insert which is separated or unwound to increase surface area for the adhesive 40 to bind to. Preferably, the broom 54 is closer to the first end 34 of the sleeve 30 than the stem 52. The broom can comprise part of the rope insert which is separated or unwound to increase surface area for the adhesive 40 to bind to. This increased surface area is highly advantageous, especially with large

the cable. Immediate pouring will ensure that the gelling stage occurs in the sleeve and not in the mixing container. Preferably, the adhesive is poured down the side of the sleeve to allow air to escape. The cap 70 may preferably be attached to the second end 36 of the sleeve 30 remote from the flemish eye in any of a number of ways, for example, welded together, with the cable 12 extending through the cap bore 72. The cap may comprise steel or other suitable high strength material. As shown in figure 2, the shape of the cap 70 is preferably conical. That is, the first end 74 of the cap has a cross section width 78 greater than a cross section width 79 of the second end 76 of the cap 70. The purpose of the cap is two fold: to provide some extra support for the sleeve to restrict relative movement, and to act as an anti-fouling member when in use. That is, the cap helps guide external elements away from the sleeve, preventing them from catching on the sleeve. This helps to ensure smooth maneuvering of the caFigure 5:.

cable assemblies in that the adhesive has more material to bind to, increasing strength of the cable assembly and helping to reduce surface cracking of the adhesive. Figures 3-5 show cross section views of the cable in the sleeve 30, taken through figure 2. Figure 3 is taken through the broom 54 of the rope insert 50, figure 4 is taken through the stem 52 of the rope insert, and figure 5 is taken where the rope insert is not present. In figures 3 and 4, the rope inserts 50 are shown positioned spaced evenly and circumferentially around both the main body 14 of the cable 12 and part of the tail 20, in the adhesive 40. Figure 4 also shows an option where the tail 20 is partially unwound. Figure 5 shows the main body 14 having a cable diameter 13 which is used to calculate a preferred length 38 of the sleeve 30, as noted above. In the preferred embodiment shown in the figures, the cable 12 comprises a core rope 17 having the outer ropes 19 wrapped around the core. Various numbers of outer ropes may be used, depending upon the intended application.

Underwater foundation leveling device Pat. 8,215,026 U.S. class 33/366.11 Int. class E02D 15/10 Inventor: Kiyoshi Saito, Hokkaido, JP. Assignee: Kiyoshi Saito, Hokkaido, JP. An underwater foundation leveling device is capable of preventing a slack wire connected to a support element with a plumb weight from colliding with reflectors. The reflectors are provided for measurement of a position of a leveling area, around an upper portion of the support element supporting the plumb weight for leveling riprap surface of underwater foundation. The support element is hoisted with the wire and then made fall by its own weight for leveling for the foundation surface. The reflectors reflect light toward a light receiving unit for a position detection for the leveling area. The device comprises, a protective element preventing the slack wire from hitting the reflectors, and a light passage located in a position allowing an optical path of the light reflected from the reflectors to travel toward the light receiving unit. Figure 6 illustrates a first embodiment according to the present invention, in which a protective element 8 is mounted above reflectors 5 which are mounted around a support element 2 having a plumb weight 1 attached to it. The pro-

tective element 8 is formed of a metal-made circular-plateshaped member, and securely welded to the support element 2. The circular-plate-shaped member forming the protective element 8 has a diameter larger than the diameter D of a circle formed by a plurality of reflectors 5 which are placed continuously adjacent to each other, in order to protect the reflectors 5 from collision with a slack wire 4 as shown in figure 6 even when the slack wire 4 collides with the outer edge of the protective element 8. Specifically, the protective element 8 has an outer edge extending outward beyond the circle formed by the continuous arrangement of the plurality of reflectors 5. The outer edge of the protective element 8 is maintained in a relational position where, when the slack wire collides with the outer edge, the wire does not collide with the reflector 5. For this reason, in the process of leveling the bottom of a body of water by use of the plumb weight 1, even if slack occurs in the wire 4, the slack wire 4 does not collide with the reflector 5, thereby damaging the reflector 5 or making the surface of the reflector 5 dirty. In addition, the protective element 8 is provided above the reflectors 5, so that an area immediately below the protective element is fully bare without any covercontinued on next page

tors 5 are not damaged and not made dirty by a slack wire 4. As in the case of the protective element 8, if a protective element is formed of a plate-shaped member, the structure of the protective element can be advantageously simplified and also a light passage can be easily provided in a size sufficient to pass light. The protective element 8 is formed of a circular-plate-shaped member in the first embodiment, but the protective element is not limited to a circular plate shape. As long as a protective element has an outer edge extending outward beyond the circumference of the circle created by the continuous arrangement of the plurality of the reflectors 5, the protective element can be formed in any shape, and, for example, it may have a polygonal outer edge. When a slack wire 4 hits the outer edge of the protective element 8, a relational position where the slack wire 4 does not collide with the reflectors 5 is varied depending on the

age to form a light passage of the present invention. Thus, the protective element 8 does not block an optical path of the light reflected from the reflectors 5 in the position measuring process. As a result, in the underwater foundation leveling device according to the first embodiment, a position measurement can be correctly carried out at any times, because the reflec-

amount of slack occurring in the wire 4, a vertical position of the protective element 8, a protruding position of the outer edge of the protective element 8, that is, the diameter of the protective element 8, and the like. Hence, the relational position can be achieved by adjusting other elements based on a predicted amount of slack occurring in the wire 4 during the leveling work performed by use of the underwater foundation leveling device. Figure 7 illustrates a second embodiment, in which the underwater foundation leveling device comprises a domeshaped protective element 9. The second embodiment is different in this respect from the first embodiment, but the

Do you want a tool or do you want a toy? When you face a tough job, you don’t want to mess around. You need a tool that works every time, every day. The Harrington LB lever hoist is built for those demanding applications, strong and reliable to get real jobs done right.

structure of other components is the same as that in the first embodiment. In the second embodiment, a dome-shaped protective element 9 is fixedly mounted on a portion of the outer periphery of the support element 2 above the reflectors 5. The outer edge of the protective element 9 extends outward beyond the circle formed by continuous arrangement of the reflectors 5. The bottom side of the protective element 9, a part of which forms the outer edge of the same, is situated above the reflectors 5, so that a light passage is formed under the protective element 9. With a structure as described, the protective element 9 does not block the optical path of reflected light when the position of the leveling area is measured. As illustrated in figure 7, even if the slack wire 4 hangs down and collides with the protective element 9, the wire 4 does not collide with the reflectors 5. As a result, the reflectors 5 are neither damaged nor made dirty by impact of the collision of the wire 4. In addition, the dome-shaped protective element 9 increases impact resistance, thus preventing the protective element 9 from being deformed or broken by impact of the collision of the wire 4. In the dome-shaped protective element 9, the hanging-down portion of the wire 4 collides with an inclined portion of the protective element 9, resulting in a reduction in the force of the wire 4 acting in the direction toward the reflectors 5. For this reason, even if a large amount of slack continued on next page

continued from previous page beyond expectation occurs in the wire 4 and the slack wire 4 collides with the reflectors 5 under the protective element 9, the impact force can be reduced to protect the reflectors 5 from fracture. Figure 8 illustrates a third embodiment, in which a pair of plate-shaped protective members 10a, 10b are disposed respectively on the upper side and the lower side of the plurality of reflectors 5 and form a protective element 10. Except for the structure of the protective element 10, the underwater foundation leveling device in the third embodiment is similar to that in the first embodiment. In the protective element 10, a light passage is formed between the protective members 10a, 10b. The outer edges of the respective protective members 10a, 10b extend outward beyond the circle which is formed by continuous arrangement of the reflectors 5. Since the protective element 10 is structured as described above, when the slack wire 4 hangs down, the wire 4 collides with the outer edges of the respective protective members 10a, 10b, thus inhibiting the wire 4 from coming into collision with the reflectors 5. In particular, when a large amount of slack occurs in the wire 4, the slack wire 4 collides with the protective member 10b which is disposed on the lower side of the reflective element 5, whereby the wire 4 is inhibited from breaking or making the reflectors 5 dirty. As a result, in the underwater foundation leveling device according to the third embodiment, the reflector 5 may not possibly be damaged. It follows that an accurate position measurement can be achieved. The third embodiment employs the pair of plate-shaped protective members 10a, 10b, but the protective members 10a, 10b are not limited to a plate shape. For example,

It follows that the wire 4 does not become a cause of either fracture nor dirtying of the reflectors 5. A fifth embodiment illustrated in figure 10 describes the case of the plumb weight 1, supported by a support element 13 of a frame form. The plurality of reflectors 5 is mounted on the outer periphery above the support element 13, and then a protective element 9 as is the case with the second embodiment shown in figure 19 is provided above the reflectors 5. Four strand blackened wire rope Pat. 8,438,826 U.S. class 57/237 Int. class D07B 1/00 Inventor: Bamdad Pourladian, Saint Joseph, MO., Timothy W. Klein, Savannah, MO. WireCo WorldGroup Inc., Kansas City, MO. The present invention is directed to a wire rope having a blackened finish designed for theatrical productions. The wire rope includes a plurality of strands that have a closed spiral arrangement with each other and are compacted. Each strand includes a center wire spirally surrounded by a plurality of inner wires that are spirally surrounded by a plurality of outer wires so that the outer wires completely encompass the inner wires. The center wire and the inner wires are made from a galvanized material and coated with a lubricant. The outer wires are made from a non-coated steel material. Each strand is compacted so the outer wires create a tight mechanical seal to protect the inner wires. The blackened finish on the wire rope is due to a black oxide coating treatment and provides for low visibility of the wire rope during theatrical performances.

Figure 11: Side elevational view of one embodiment of the wire rope.

A four-strand wire rope 30 embodying various features of the present invention is shown in figure 11. Rope 30 is ideal for use in theatrical stage rigging applications although one skilled in the art will appreciate that rope 30 may also be useful in other application including, but not limited to, mobile crane hoist rope, helicopter rescue hoist rope, marine mooring lines and marine towing lines. In one embodiment, rope 30 is constructed in a substantially rotation-resistant 4x31 configuration. One skilled in the art will appreciate that rope 30 may also be useful in other configurations including, but not limited to, 4x19, 4x26, 4x36, 4x41, 4x49 and similar configurations. Rope 30 is coated with a blackened finish for low visibility during theatrical performances. In a first embodiment, shown in figure 12, a strand 10 includes a center wire 12 surrounded by eighteen inner wires 16. Center wire 12 and inner wires 16 are generally cylindrical and are constructed from high-carbon steel drawn to size galvanized wires which have a thin zinc coating. Rope 30 may have a diameter ranging from about 1/8 inch to 5/8 inch. Center wire 12 and inner wires 16 are drawn with a continued on next page

Center wire 12, inner wires 16, and outer wires 22 are used to produce strand 10 using a known stranding process. Once strand 10 is made, it is compacted using a known in-line compaction method. In one embodiment, stranding and compacting wires 12, 16 and 22 occurs simultaneously using known processes. Because rope 30 is often used to suspend performers wearing delicate and expensive costumes during theatrical performances, it is

Lubricant 20 provides for internal lubrication between center wire 12 and inner wires 16, between inner wires 16, and between inner wires 16 and outer wires 22. Alternatively, center wire 12 and inner wires 16 may be constructed from corrosion-resistant materials or other appropriate materials that include a corrosion-resistant coating and then lubricant 20 is applied to an outer surface 14 of center wire 12 and to outer surfaces 18 of inner wires 16.

of strands 10 are helically-laid around a center (not shown) that may be an additional wire or may be empty space as shown in figures 14 and 15. It will be appreciated by one skilled in the art that wire rope 30 may comprise three, four or more strands arranged in a spiraled arrangement. Figure 15 illustrates rope 30 after compaction. Rope 30 undergoes a compaction process such as, for example, swaging or roller die compaction that further compacts rope 30. After compaction, rope 30 undergoes a black oxide coating treatment. Any black oxide coating method may be used, such as, for example, cold applied, low temperature, standard high temperature or other appropriate black oxide coating method now known or that may be known in the future. In order to eliminate the problem of flaking that can occur when the blackening is done through a powder coat treatment, the blackened finished of rope 30 occurs through a continued on next page

undesirable for outer wires 22 to contain any type of liquid or gel-like lubrication, as those types of lubrication can stain and ruin the costumes. Therefore, outer wires 22 that form rope 30 of the present invention are produced substantially without any liquid or gel-like lubrication. However, a lack of lubrication can cause premature red rust formation on wires 16. In order to substantially eliminate this problem, center wire 12 and inner wires 16 are made from drawn-galvanized high-carbon steel wires that have a thin zinc coating and are coated with lubricant 20. Additionally, lubricant 20 may be applied by baking it on the wires or spraying it on the wires and letting it dry at room temperature. Figure 13 illustrates strand 10 in a compacted state. The compaction of strand 10 flattens (plastically deforms and shapes) outer wires 22 in a manner that creates a mechanical seal 26 thereby creating a tight barrier so that liquids, chemicals or other gels cannot penetrate to inner wires 16. The compaction of strand 10 deforms center wire 12 and inner wires 16. Lubricant 20 is pressed in between and generally stainless fills all of spaces 24 between center wire 12 and inner wires 16, between inner wires 16, and between inner wires 16 and outer wires 22.

continued from previous page black oxide chemical conversion process. This process may be adversely affected if the black oxide chemical is contaminated by zinc contained in inner wires 16. Therefore, it is important that inner wires 16 containing zinc are not exposed to the chemicals used in the black oxide treatment. This is accomplished by first compacting each strand 10. The compaction of strand 10 causes the flattening (plastic deformation and shaping) of outer wires 22 and cause outer wires 22 to butt up (wedge) against one another thereby forming tight mechanical seal 26 and preventing the liquid black oxide chemical from coming into contact with inner wires 16. The blackened finish decreases the visibility of rope 30 for use in theatrical stage productions. Crimped or swaged couplings for cable reinforced hoses Pat. 8,439,405 U.S. class 285/256 Int. class F16L 33/00 Inventor: Ron Trujillo, Highlands Ranch, CO., Jonathan Clark Swift, Cambridge, GB., Lance D. Miller, Highlands Ranch, CO. Assignee: The Gates Corporation, Denver, CO. A hose coupling for fitment to an end of a cable reinforced hose includes a unitary stem having a cable trap groove portion having an outside diameter greater than an inside diameter of a tube of the hose and less than an inside diameter of the hose with the tube skived from the hose. A unitary ferrule defines at least one cable trap rib corresponding to the cable trap groove and having an inside diameter less than the outside diameter of the cable reinforced hose and greater than an outside diameter of the hose with material covering the cable skived from the hose. The groove width is at least the width of the rib plus twice the diameter of cable reinforcing the hose. Epoxy may be disposed between the hose tube and the stem for sealing or injected between the ferrule and the stem permeating the cable. Figure 16 is a quarter sectional view of an embodiment of coupling 200 of the present invention. In figure 17, coupling 200 is deployed, uncompressed, on cable reinforced hose 305, which may be a blowout preventer choke and kill hose, or the like. Hose coupling embodiment 200 includes unitary stem 202 and unitary ferrule 201, which may be welded 203, staked or otherwise secured together, such as through the use of circular plate 204, or similar mechanism.

ing cable reinforcement 320 into groove 215. Preferably, this traps cable reinforcement in the double-skived area between rib 236 and groove 215. Also, in accordance with various embodiments, at least some of the individual cables making up cable reinforcement 320 are deformed by the compression of the cable trap rib, particularly compression of the cable trap rib, with respect to the uncompressed cable trap groove. This deformation of individual cables is best seen in enlarged figure 19. Entrapment of the cable by the compressed cable trap, comprised of rib 236 and groove 215, secures coupling 200 to hose 305 in a manner that does not depend on gripping rubber or polymeric material, such as cover 333 and/or inner tube 317. Rope tester detection plate Pat. 8,476,898 U.S. class 324/240 Int. class G01N 27/82 Inventor: Koichiro Nishiyori, Tokyo, JP., Hiroshi Sasai, Tokyo, JP., Takashi Yoshioka, Tokyo, JP. Assignee: Mitsubishi Electric Corporation, Chiyoda-Ku, Tokyo, JP. In order to examine abnormality in shape of an outer circumference of a wire rope, the rope tester device includes a comb-shaped detection plate having a curved test edge portion extending along at least one portion of an outer circumference of a substantially circular sectional configuration of the wire rope and a testing recessed portion for receiving the wire rope in the vicinity of or in contact with the test edge portion, and a support device for rotatably supporting the detection plate in the vicinity of or in contact with the wire rope for permitting the rotation of the detection plate when the detection plate receives a force from an abnormal portion of the wire rope to relieve the force. A test string is disposed in an opening of the testing recessed portion for testing a surface that is not in the vicinity of or in contact with the test edge portion. In figure 20, a hoistway 1 of an elevator has provided at its top portion a machine bed 2 on which a machine room 3 is defined. Within the machine room 3, a hoist 4 and a deflector sheave 5 are disposed, around which wire ropes 6 for moving an elevator car are wound. A rope tester device 7 of the present invention is disposed at a position close to the wire ropes 6 extended between the hoist 4 and the deflector sheave 5 on the machine bed 2. The rope tester device 7 comprises a detection plate 8 dis62

As best shown in figure 21, the detection plate 8 has a curved test edge portion 10 extending along at least one portion of an outer circumference of a substantially circular cross-sectional configuration of the wire ropes 6, and a recessed portion 11 for receiving the wire ropes 6 in the vicinity of or in contact with the test edge portion 10. In the illustrated example, the recessed portion 11 of the test edge portion 10 extends along about 1/2 of the outer circumference of the circular cross-sectional configuration of the wire ropes 6. The detection plate 8 has provided with a comb-shaped member 12 having a number of the recessed portion 11 in correspondence with the number of the wire ropes 6 to be tested, this being desirable in that the plurality of wire ropes 6 can be simultaneously tested at a single pass of the wire ropes 6. In the illustrated example shown in figure 21, twelve wire ropes 6 are used, so that the comb-shaped member 12 has twelve recessed portions 11 and thirteen parallel tooth portions 13 defining the recessed portion therebetween. The number of the recessed portion 11 of the detection plate 8 is desirable when it corresponds to the number of the wire ropes 6 to be detected, but the detection plate 8 with a plurality of the recessed portion 11 may be used for a single wire rope 6. The configuration of the curved portion of the recessed portion 11 of the detection plate 8 is desirable when it is circular, it may be a polygonal as long as the detection edge portion 10 in the vicinity of or in contact with the outer

circumference of the wire ropes 6 and extending in the circumferential direction can be provided. The detection plate 8, which may be constructed as a single plate-shaped member, comprises in the illustrated example the comb-shaped member 12 in which the recessed portion 11 is formed and a base 14 for holding the combshaped member 12 as a separate part and connectable to the support device 9. With such a structure, when the rope tester is to be used in an elevator having a different pitch or the number of ropes, the tester can be used by changing the comb-shaped member 12 only. When there are twelve wire ropes 6 as illustrated, the detection plate 8 shown in figure 21 can be used, and when there are six wire ropes 6, a combshaped member 15 having a six recessed portion 11 and a seven teeth portion 13 as shown in figure 22 can be used. Also, the comb-shaped portion in the vicinity of or in contact

with the projection portion of the rope, which is a wearable portion, can be minimized. The comb-shaped member 12 is detachably and adjustably held on the base 14 by a fastening means such as an elongated hole 16 and a wing screw 17 so that the comb-shaped member 12 can be easily replaced and the comb-shaped

The test string 18 is disposed in grooves 19 provided at teeth portions 13 defining an opening of the recessed portion 11 of the comb-shaped member 12. Lifting assembly Pat. 8,523,253 U.S. class 294/82.34 Int. class B66C 1/36 Inventor: Joseph A. , Hartford, WI. Assignee: Konecranes Plc., Hyvinkaa, FI. A lifting assembly includes a link member defining a pivot axis and a latch axis. The lifting assembly also includes a latch pin and a jaw member. The jaw member is pivotally coupled to the link member about the pivot axis and selectively fixedly coupled to the link member about the latch axis by the latch pin. The jaw member defines a cam surface. Engaging the cam surface with a load rotates a portion of the jaw member into alignment with the latch axis, such that the latch pin may be received by the jaw member and the link member. Referring to figure 24, a lifting assembly 10 includes an upper assembly 14, a swivel 18, a link assembly 22, and a jaw member 26. The lifting assembly 10 is configured to engage a load for lifting and movement. More specifically, the lifting assembly 10 is configured to engage a trunnion 30, as shown in figures 25-27 of a load. The trunnion 30 may be coupled, for example, to a nuclear fuel assembly, a nuclear fuel cask, or other load. Referring to figure 24, the upper assembly 10 includes a body 34 that rotatably supports an arrangement of pulleys 38. The pulleys 38 facilitate raising and lowering the lifting assembly 10, including an attached load, when used in conjunction with a wire rope (i.e. a metallic cable) and a hoist motor (not shown). The swivel 18 is rotatably coupled to the body 34. The swivel 18 includes a connecting portion 50 for pivotally sup-

The first support extension 54 and the second support extension 58 each define a swivel aperture 62. The link assembly 22 includes a link body 66. The link body 66 includes a support portion 70 for pivotal engagement with the support extensions 54 and 58 of the swivel 42. The support portion 70 defines a link support aperture 74 (figures 25-27). With the support portion disposed between the first support extension 54 and the second support extension 58, the link support aperture 74 is aligned with the swivel apertures 62 along a link pivot axis 78, as shown in figure 24. A link pivot pin 82 is inserted through the swivel apertures 62 and the link support aperture 74 to pivotally couple the link assembly 22 to the swivel 42. A link pivot retainer plate 86 is fixedly coupled to the support portion 70 to inhibit the link pivot pin 82 from movement. The link body 66 further includes a first leg portion 90 and a second leg portion 94. The first leg portion 90 defines a first jaw cutout 98 for receiving a portion of the jaw member 26. The first leg portion 90 further defines a link pivot aperture 104 oriented along a jaw pivot axis 108. The jaw pivot axis 108 is substantially parallel to the link pivot axis 78. A jaw pivot pin 112 is disposed within the jaw pivot aperture 108. A jaw pivot retainer plate 116 is fixedly coupled to the link body 66 to inhibit the jaw pivot pin 112 from movement. The second leg portion 94 defines a second jaw cutout 120 for receiving a portion of the jaw member 26. The second leg portion 94 further defines a link latch aperture 124 oriented along a jaw latch axis 128. The jaw latch axis 128 is substantially parallel to the link pivot axis 78 and jaw pivot axis 108. A trunnion recess 132 is defined in the link body 66, between the first leg portion 90 and the second leg portion 94. As illustrated in figure 26, the trunnion recess 132 is sized and configured to slidably receive the trunnion 30 during actuation of the jaw member 26. The trunnion recess

Van Beest’s shackles are found to comply with: •  DNV 2.7-1 Offshore Containers •  EN 12079-2 Offshore containers and associated lifting sets •  EN 13889 Forged steel shackles for general lifting purposes •  IMO/MSC Circular 860 •  US Federal Specification RR-C271D

The low-profile LiftMat™ lift table from Southworth Products descends to just 3¼ inches above the floor and accommodates any skid or pallet, including closed-bottom designs. According to a company release, the ergonomic table minimizes back strain while reducing costs and raising productivity. When the unit is equipped with an optional diamond-plate ramp, workers can feed and offload it with a hand pallet truck or rolling cart, making it ideal for use in tight spaces, work cells, or anywhere that a fork lift is unavailable. The user can access loads from all four sides with no bending and minimal reach-over, reducing worker fatigue and injuries. As boxes are added or removed, the platform is smoothly raised or lowered to the most comfortable height with a powered foot switch, a hand-held push-button remote, or a wall-mounted switch. A full-perimeter, auto-stop safety toe guard instantly stops descent when it comes in contact

In 1924, Germany’s ‘Adolf Bleichert & Co.’ celebrated its 50th Anniversary. By the time of this occasion, the company had designed and built the world’s record holding wire ropeways: Longest and highest elevation (Argentina); Length of system over water (New Caledonia); Steepest (Tanzania); Highest capacity (France); Northernmost (Norway); and, Southernmost (Chile). Written by the great-great grandson of the company’s founder, this book includes over 100 pictures and detailed engineering drawings that explore the legendary company’s history, and several of its record-holding systems.

with any obstruction. Because it does not require a pit, the unit can be relocated as needed and can be used in leased buildings or on upper floors where pits cannot be built. Loading and unloading unpalleted boxes with a two-wheel hand truck or dolly is easy, especially with the optional ramp. Other applications include machine feeding, raising malfunctioning equipment to a comfortable level for repair work, assembly work positioning, and transferring loads between levels. Capacity is 2,200 pounds. Raised height is 31½ inches. Made of sturdy, structural steel, the LiftMat is available with 15 platform sizes, ranging in 6-inch increments of width and/or height from 24 x 60 inches to 48 x 72 inches. All pivot points have lifetimelubricated bearings.

Now available with USA made chain, assembled and tested in USA.

Sometimes shackles are not used for lifting applications but for more permanent constructions. According to a

recent company release, these can be subject to dynamic loads and/or ex-

treme vibrations. In such applications there is a risk that, over time, the nut starts moving over the thread. To avoid this risk Van Beest offers a range of Green Pin® Fixed Nut Shackles. Green Pin® Standard, Polar and Super shackles can be equipped with a feature that consists of an extra AISI 316 securing bolt which is drilled through the nut and shackle pin. This securing bolt is fastened with two sets of Nord-Lock washers and a securing nut. This will keep the shackle nut in position. The Nord-Lock wedge-locking washers lock when subjected to extreme vibration or dynamic loads. Green Pin® Fixed Nut Shackles will be available on request only.
