Control cables for energy chains

We rely on cores wound in bundles.

Starting at 12 cores, our control cables have a special mechanical design for long service life in motion. We install so-called cores wound in bundles with short pitch lengths.  

But what exactly are cores wound in bundles? 

The number of bundles into which the cores are wound depends on the number of cores. These bundles are then stranded in turn. This method is necessary to absorb the pull/push forces which occur during movement. These forces arise when the cable moves around a curve (radius). The cores are compressed in the inner radius and stretched in the outer radius. We developed the cores-wound-in-bundles design to ensure that these forces do not put too much strain on the cores, since a core thus continually changes its position in the cable, balancing out the forces. It is especially important for preventing the so-called corkscrew effect, which often occurs on long travels. 

Seven reasons for our chainflex cable

Cables in a forklift - a special challenge

For us, a very exotic application is rolling up and down on plastic rollers on a forklift mast. Tension is maintained on the cable so that it does not jump off the roller when the vehicle starts moving. Deflection with these rollers also puts the stranding under extreme strain. A customer who performed very conscientious testing discovered years ago that this can lead to problems. We were allowed to take part in the customer's tests with our products, and we showed that our cores-wound-in-bundles solution relieves forces on the cores. Years later, corkscrews and broken wires in the cable in this application have long been forgotten. Facing challenges that your cable cannot currently handle can be a first step to finding a solution with us.
