There were around 80 entries for the first Vector Awards two years ago, which was only open to European entrants. In contrast, this year more than 110 entries were submitted from all over the world: from China, India, Korea, and Singapore, to the USA, Canada and Brazil, and right across Europe.

The gold award and €5,000 prize money went to the Czech power supplier CEZ Group for the longest travel in the world ever to be accomplished with a plastic cable carrier: 2,018 feet in a lignite-fired power plant in Tušimice. A heavy-duty roller cable carrier system from igus’ 5050 RHD series is installed on the conveyer unit of the lignite excavator, which operates in extremely demanding conditions. Roller cable carriers, developed by igus for long distances, have been in use around the world for more than ten years.

CEZ Group says the robust system – which is also equipped with igus’ Chainflex® continuous-flex cables – makes a significant contribution to operational safety. System downtimes caused by cable breakage, for example, have been reduced to zero compared with before.

The jury awarded the silver Vector Award to the National Mineral Development Corp. Ltd. (NMDC) in Hyderabad, India. The state company belongs to the Ministry of Steel and carries out exploration work, among other things.

NMDC use a 61-feet long plastic cable carrier system with a rearward bending radius (RBR) on a bucket-wheel reclaimer in a steel mine. The reclaimer can rotate by +/- 180 degrees, while operating in an area that is difficult to access. The loads the cable carrier must withstand are enormous: the cables in the cable carrier alone weigh over 36 pounds per foot.

The heavy steel chain used previously in this application was damaged after just two years. According to NMDC, the igus cable-carrier system has been running reliably and with little maintenance and no downtime since its installation.

The bronze Vector Award and €1,000 prize money went to Rene Petsch, a design engineer from Deckel Maho Seebach GmbH. In this application, a traveling column milling machine underwent advanced development to make it more accurate, adaptable and economical than its predecessor. The rigid machine bed made from composite mineral and the symmetrical traveling column were to ensure improved precision.

To keep the design space compact, the Y and Z-axes of the machine use just one cable carrier: System E4.1 from igus. The E4.1 system ensures higher lateral stability, which was necessary due to the high lateral acceleration through the X-axis of 26 feet per second². The cable carrier was attached in an upright position with the run bent in at one side.

All the cable carriers applications submitted can be found on the competition website at www.vector-award.com. Video content is also available for certain entries.

The Vector competition was run in conjunction with the German Central Association for Electrical Engineering and Industry (ZVEI), the tooling laboratory (WZL) of the RWTH Aachen and TÜV Rhineland. The Vector Award is under the patronage of the Industrial Automation sector of the Hanover show.

Cable carriers—also widely known as Energy Chains®, cable tracks, cable chains and drag chains—are the umbilical cord of modern machines and ensure the safe supply of energy, data and other media. Cable carriers are suitable for multi-purpose use in the crane and machine-tool industries, as well as in robotics, cleanrooms, material handling, and more.

Debris and chips can become trapped between a cable carrier’s upper and lower runs as they glide on top of one another. Guidelok’s design keeps the upper and lower runs separate via a spring-loaded roller support, which is pushed back as the cable carrier passes through, before snapping out again after the radius has passed. The upper run rests on the roller support and is not allowed to glide on the lower run.

The system not only works to reduce abrasion and wear caused by trapped chips and debris, but also offers a number of other advantages. The system means the cable carrier can support itself over a longer distance. This enables users to choose a smaller version for the given length, saving overall costs and reducing the required push-/pull driving force. Guidelok keeps the upper and lower runs of the cable carrier separate from one another, which helps to minimize friction and wear and thereby increases service life.

The horizontal Guidelok system is already being used successfully by one machine-tool manufacturer, who replaced a heavy steel chain with this solution. A more traditional solution would have allowed large metal chips to settle in the inner radius between the upper and lower runs of the cable carrier, which could have caused damage. In contrast, the new system is ideal for such applications. Guidelok is also lower cost than most steel chains or sophisticated gliding systems.

New Guidelok is designed to be modular—the side troughs are optional—and is currently available from igus North America with a three week lead time. A movie illustrating the new design can be found at www.igus.com/ApplicationCorner/ec_videos.asp. Alternatively, call 1-800-521-2747 or e-mail sales@igus.com for more information.

igus® is using the FABTECH show in November to launch the new-style “RX” energy tube, which has a specially designed, smooth domed exterior onto which debris—such as metal or wood chips—can not attach itself. Connecting parts are concealed on the interior to facilitate this. Comprehensive tests—including underwater experiments—have been carried out in igus®’ test laboratories which confirm the new energy tube is 100 percent airtight.

Despite this, the RX energy tube can be easily opened using a screwdriver to unscrew bolts integrated into the outer radius of each link. There is also a very large interior space for cables and hoses, which can be separated using vertical separators, and a horizontal shelf to safely route cables and hoses and thereby prevent abrasion. Both these features mean maintenance and machine downtimes are reduced to a minimum.

The new energy tube is well suited to short, self-supporting lengths inside tooling machines. The chip-proof cable carrier was also developed to be used in reverse bending radius (RBR) applications. The RX energy tube is available in a high-temperature version, made from the special, high-temperature material “igumid HT”. This version ensures that even red-hot chips up to 1,562 degrees Fahrenheit fall off the tube rather than melt onto it. The enclosed cable carriers can also be delivered as pre-assembled ReadyChains®; ready harnessed with cables, hoses, and internal separators, as required by the customer.

The upper portion of a conventional cable carrier glides on the lower portion over longer distances. However, requirements for cable carriers in long travels have been increasing in recent years. Travels over thousands of feet present new challenges in crane construction, as do high travel speeds and cable loads up to 33.6 pounds per foot. As length of travel, load and speed increases, so does friction, which can lead to premature wear and load problems for a cable carrier.

This new-found need to expand the technical limits of cable carriers was behind the development of Rol-E-Chain. With its unique design, friction is decreased and travels over 2,600 feet are achieved easily at speeds up to 32.8 feet per second. Moreover, the drive power required to move the cable carrier is reduced by more than 25%. Rol-E-Chain is also resistant to applications involving harsh environmental conditions, such as thick dirt.

The cable-carrier design is ideal for applications on cranes, material handling devices, plasma cutters and high-speed transfer systems.

The need for ever-increasing speeds demands advancements in cable carrier technology. Similarly, cable carriers must operate smoothly and quietly because many ports are expanding and moving closer to residential areas. P4 is especially low noise and wear resistant at high speeds, even with loads up to 20 lbs/ft. In fact, thanks to the use of additional center links, there is practically no weight limit. Each link has the same short pitch, which means the cable carrier moves with minimal vibration in its radius. Plastic bridges and grooves along the surface of the cable carrier —a design from igus for long travels called ‘AUTO-GLIDE’ —mean the upper run of the P4 chain glides smoothly over the lower run.
The plastic rollers are firmly integrated into the sides of the cable carrier and do not rotate over one another, because the cable carrier’s upper and lower runs offset. This reduces wear and increases service life.
