e-drum - compact without slip ring

... Can be rolled onto a drum flexibly – cables are protected ...

A modular system enables flexible adaptation to the use in question. The modular system of the e-drum enables the user to create a compact and durable guidance and drum-reeling system for energy, data, air and fluids.

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.
