e-spool for stage and theatre use - design study

Certified for stage and event technology according to DIN EN 17206 and DGUV principle 315-390

Safely guide many different cables in a confined space with e-spool. e-spool uniquely combines two different energy supply systems: one standard energy chain is guided by a roller, providing the correct length and tension of the energy supply system through an integrated spring. In the home position, the energy chain is completely rolled up to save space. The twisterband connects the roller with the shaft end block, serving as an interface to the supply side cables.

e-spool with smart sensor monitors

Reliable energy supply thanks to intelligent sensor monitoring systems

The e-spool now comes with various sensor monitoring: the spring force of the three springs included is monitored with the help of a load cell sensor. If the force falls below the specified value, the user is prompted to replace the spring. When the​ specified value is exceeded, there is a blockage that must be removed.

The rotation sensor monitoring, which counts the drum rotations and determines the position of the chain and more.
