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 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

SRM-L light steel rotation module

Simply reliable rotation

A standardised guide trough for various chain widths, including preparation for smart plastics end position control

• Price reduced by up to 40% compared to SRM
• Design based on the proven PRM system
• Fewer parts, reduced material usage
• Preparation for end position control

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

Light and cost-effective

Discover all the advantages of an e-chain® with a new guide concept for travel distances of up to 10m. The system was designed for use on various shaft end supports and based on DIN EN 17206 and DGUV Principle 315-390.

• More than 50% weight reduction and thus higher payload
• Price reduced by up to 50% compared to the standard zig zag basket
• Lower drive power thanks to weight reduction
