Twisting Through Three Thousand Degrees

POSTED 10/13/2010

rong>New cable carrier for circular movements in small spaces

EAST PROVIDENCE, R.I. – igus® has now developed an innovative, compact cable carrier system that can turn through 3,000 degrees in minimal space. TwisterBand TB30 guides energy, data and media with little wear and is extremely cost effective. At high rotating speeds, the cable carrier stays close to the axis.

Where demanding rotary movements are required at very high loads, igus cable carriers with reverse bending radii (RBR) are usually used. With these, circular movements up to 540 degrees are possible. However, the installation spaces involved are usually large in terms of depth and width. As a medium-sized solution in the igus’ circular cable carrier range, a second possibility is the TwisterChain cable carrier. This sturdy, smooth-running cable carrier was designed for one and a half complete rotations, coupled with high dynamics. The system’s diameter is takes up more height, less width, and comes nearer to the axis of rotation.

New: Fast lightweight micro-solution

Where installation space is extremely limited, on the other hand, a different, compact and very easy to fill micro-solution is required. Following months of development work, the igus design engineers have presented such a solution.    

New TwisterBand TB30 makes rapid rotating movements possible up to 3,000 degrees and depends only on the belt length or design height in the axis of rotation. The smaller masses involved mean much lower centrifugal forces and possible rotary speeds up to 720 °/s. Thanks to the small installation size and compact design, this cable carrier system can be used safely in all installation positions: horizontal or vertical.

Compact and straightforward

The polymer cable carrier is lightweight and easy to use. The injection-molded chain has easy access links allowing users to simply press in cables and hoses through split openings.

The design is modular and extremely flexible and does not have to be customized to individual customer specifications. One type is already available, with further larger and smaller versions planned.


Applications for the slim design circular chain system are mainly in robotics supplying one and six axes in special machine construction, handling, lifting and assembly equipment, and test jigs.
