E4Q | Tool-free for faster assembly

Quieter, robust, easy-to-install e-chains®.

The E4Q series of e-chain® is designed to provide the best possible solution for unsupported lengths and long travels. Based on the robust e-chain® standard E4.1, which has been tried and tested for over 12 years, the new series offers a longer service life and a higher level of modularity.

The crossbars feature an easy-to-open mechanism which does not require any tools. Simply, lift the latch with your finger on each end to remove and snap it shut to attach. This innovative new solution cuts the assembly time by up to 40% compared to the standard E4.1 e-chain®.

Typical areas of application: machine tools, crane systems, automation systems

E4Q/H4Q e-chain® series features

Crossbars - the e-chain® can be opened and closed without any tools at all. Crossbars and shelves lock in the side section for even greater holding strength. The e-chain® can be filled in considerably less time.
Save weight – This new design has reduced material that did not provide functionality 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.
Vertical and horizontal stop-dogs – the vertical stop-dogs provide extra rigidity and allow large unsupported lengths. The horizontally arranged stop-dogs 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.
Optional noise dampening – 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-chain®.

NEW: universal interior layout

Depending on accessibility, choose the side from which you want to fit the shelf and see whether it is easier to access the inner or outer radius of the energy chain in order to release the crossbars. The shelves are locked in place by means of the integrated slider and automatically when the crossbar is fitted. Thanks to positive-locking, assembly is possible with virtually no force. Locking is simple and fast, but the shelves are held securely in place. To unlock, release the crossbar on the inner or outer radius, depending on accessibility. The new E4Q e-chains can be opened quickly and without tools. After the crossbar has been released, the shelf can be unlocked by means of the slider and then simply pulled out.

How to Assemble E4Q

Complete flexibility, safety and ease of installation in one

Opening of the lock via integrated slider.

Shelf can be used in several layers and locked

Lock is automatically activated.

Design study: Clever, modular extender crossbar design E4Q

Modular extender crossbar concept with E4Q opening mechanism: adapt energy chain individually to hose diameter. Easily install without tools and replace hoses as needed.

Large hoses
The modular extender crossbar means maximum flexibility and adaptation to hose dimensions
Save assembly time: simple, fast and tool-free assembly
If a repair is required, the hose is quickly replaced by opening the crossbar on the extender crossbar
