This is how the e-drum is designed

The design study is mainly characterised by its closed system and compact structure. On the inside, there is a triflex R e-chain that enables three-dimensional movements of the cables in any direction. Due to the special design, no slip ring is needed to wind the triflex R onto a reel and the cables are securely protected in the closed e-chain.
1. Closed housing 
2. Three-dimensional triflex R energy chains
3. chainflex cables


Possible use



e.g. on a container crane
