Theatre e-spool®

e-spool® energy chain system - for theatres and stages

Discover the energy chain system for theatre and stage operations based on DIN EN 17206 and DGUV Principle 315-390. The e-spool® is a cable guidance system with automatic retraction (spring tension). A new tension-optimised e-chain® is guided with a drum and uses an integrated retaining spring to ensure the correct length and tension for the energy supply system. The twisterband connects the drum with the shaft end block, which serves as an interface to the permanently installed cables.

• Different media types and sizes safely and reliably guided in one system
• Price reduced by up to 50% compared to previous e-spool® solutions
• Developed following DIN EN 17206 and DGUV Principle 315-390
• Optimised manufacturing process through standardised parts
• Spring force/rotary sensor monitoring (optional)

Complete zig-zag system

Up to 15 metres high on the shaft end support

The new standard in the theatre and stage technology industry features greatly reduced weight on trusses; modular design and travel lengths of 5-15 metres. The new system is rounded off with fasteners for trusses, a support plate on the moving end, and an optional safety package that can be ordered based on DIN EN 17206 and DGUV Principle 315-390.

• Price reduced by up to 30% compared to the previous design
• Save up to 20% cost
• Low-maintenance and modular system

Design study: Low-cost zig-zag e-chain®

Light and cost-effective

All the advantages of an e-chain® with an innovative guide concept for 
travels of up to 10 metres. The system was developed for use 
on different shaft end supports and is based on DIN EN 17206 and 
17206 as well as DGUV Principle 315-390. The current 
system length is 2 metres. Different chain widths are possible 
are possible, internal widths from 075 to 150mm are planned.

• Weight is less than half of that of the standard zig-zag basket, allowing for a higher payload
• Price reduced by up to 50% compared to the standard zig zag basket
• Lower drive power thanks to weight reduction
• Quiet polymer e-chains®
