In the pulle-chain, chain links are only needed as elements to guide cables. Push-pull forces are no longer applied to the chain in the conventional way. Instead, the cable-guiding elements are suspended by tensioning cables and guided by means of a moving carriage and a deflector. By lowering the acting forces, cable routing with reduced vibration and wear is ensured and longer travels can be achieved irrespective of the chain size.
Statement by the Jury
Due to its innovative design, the pulle-chain overcomes the limitations of traditional energy chains and ensures economical operation.
