New igus lightweight energy chains for unsupported lengths and long travels

Treotham introduces a new generation of lightweight energy
chains by igus, designed for unsupported lengths and long travels.

The new igus E4Q e-chains feature chain links with a
smooth, contoured design and a completely new crossbar concept with locking
straps for weight reduction. These ensure that the new energy chains can be
opened and closed in seconds without tools. Specifically developed for the
special requirements of unsupported lengths and long travels, the energy chain
was first presented by igus as a prototype at the Hannover Messe 2019.

High unsupported lengths and long travels with large
fill weight create extreme stress on energy chains. The igus developers have
designed the E4Q e-chain for such application scenarios. Based on the robust
energy chain standard E4.1 from igus, the new series brings along 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. Despite material recesses, the new development has high
strength and stability comparable to the E4.1 series.

tool-free installation with new crossbars

The crossbars in the E4Q can be opened and closed
completely 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 percent. The new crossbar has
significantly higher pull-out forces than its counterparts in the locked state
thanks to its innovative design.

noise dampening optional

The special design of the e-chain results in very
quiet movement. However, if the user desires additional noise reduction, igus
has integrated an optional system in the inner horizontal stop-dog for the E4Q.
These are two connected balls that dampen the impact during the radius and
extension stop. The balls are made of a new noise-optimised and soft material
that further reduces the sound level without restricting the stability of the
