E4Q/R4Q system – the latest generation of e-chains®

E4Q/R4Q is designed to provide the best possible solution for unsupported lengths and long travels. In addition to insights from worldwide applications with the E4.1 series and the resulting optimisation, competitive analysis and customer surveys have been conducted to make the energy chain better, more cable-friendly, easier to assemble and operate, and optionally quieter.
Typical application areas: applications with large unsupported lengths, high fill weights and long travels

Technical data such as unsupported lengths and maximum travel lengths have not yet been fully determined.

E4Q/R4Q system  


Optional noise dampening – new concealed system for noise reduction. Can be retrofitted any time. Rubber elements attached to the horizontal stop-dogs additionally dampen the impact noise of the already very quiet e-chains.


Vertical and horizontal stop-dogs –  the vertical stop-dogs provide extra rigidity and allow large unsupported lengths. The horizontally arranged stop-dogs, on the other hand, are particularly important if the e-chain needs a certain degree of flexibility and durability in areas with excessive bending, for example, over long travels.


Crossbars (e-chain)/lid (e-tube) – the e-chain and e-tube can be opened and closed without any tools at all. Crossbars and lids/shelves lock in the side section for even greater holding strength. The e-chain/e-tube can be filled in considerably less time.


Save weight – Due to new findings, material has been left out where it has no function with regard to the load on the e-chain . This has happened both inside, between the stop-dogs, as well as outside. In the process, nature-inspired rounded shapes were used for the design.
