igus e-spool cable drum system

Click2Contact

The igus e-spool is a compact, spring-driven cable drum system that can safely guide energy, media or fibre-optic data cables, and can extend cables and hoses up to 21 metres without the need of a motor.

A standard e-chain, which is guided by a guide roller, is designed to always ensure, with an integrated retaining spring, the correct length and tension of the e-chain system. An igus twisterband is responsible for the rotational movements. This structure makes movements in every direction possible.

The e-spool has evolved from customer requirements and covers the gap between the spring-driven standard e-spool for up to 14 m extension length and the motorised e-spool for large projects, eg, in the offshore sector. The system has been equipped with a larger twisterband for a higher filling. To compensate for the payload and extension length, the structure of the e-spool provides more bracing, a more stable all-enclosing body and a reinforced floor plate as a retraction safeguard. In order to withstand the higher forces, the developers also opted for an optimised mechanism for adjusting the spring force. The 21 m e-spool is available either as a spring-driven version with 2 HD springs or as a motor-driven version with a built-in stationary motor.
