igus E4Q lightweight energy chain

Click2Contact

The E4Q lightweight energy chain from igus has been specifically developed for the special requirements of unsupported lengths and long travels.

High unsupported lengths and long travels with large fill weight create extreme stress on energy chains. Based on the igus E4.1 energy chain, the E4Q series offers a long service life and a high degree of modularity. In order to optimise material and therefore the weight of the energy chain, shapes inspired by nature are used. The smooth, contoured design can be found on the outside of the chain links as well as on the stop-dogs.

The crossbars on the chain can be opened and closed without tools. On the top of the crossbar, there are two hollows for the fingers, by which the locking hooks can be easily pulled up. Unlocked on both sides, the crossbar can be removed with little effort. This allows the easy opening and closing of the chain even in a guide trough and accelerates the filling of the e-chain by up to 40%.

If the user requires additional noise reduction, igus has integrated an optional system in the inner horizontal stop-dog. These are two connected balls that dampen the impact during the radius and extension stop. The balls are made of a noise-optimised and soft material that further reduces the sound level without restricting the stability of the stop-dogs.
