Power supply
For crane main power and data supply a motor cable drum or – for short travels – a spring tension drum is usually used. Busbar systems for the main power supply are also very common in indoor cranes. As an alternative to the two solutions, an energy chain can be used, which can offer various advantages.
Reliable and dynamic cable management is one of the greatest challenges in modern crane technology. Virtually all modes of crane applications are facing intensifying requirements regarding travel distances, speeds and precision.
