Slim, strong, quick to fill
Opening the e-chain without tools
The chain links of the new E4Q energy chain from Igus have a "creek pebble" design to reduce weight and a new opening bar concept with locking tabs. These ensure that the series can be opened and closed in seconds without tools.
Long unsupported lengths and long travel distances with high filling weights are extreme loads for energy chains. The Igus developers have therefore designed the E4Q E-Chain precisely for such application scenarios. Based on the robust E4.1 energy chain standard, the new series offers a long service life and a high degree of modularity.
Naturalistic-inspired shapes are used to optimize the material and therefore the weight of the energy chain. The creek pebble-shaped design can be found on the outside of the chain links and on the stops. Despite the material cut-outs, the new development has a high level of strength and stability, comparable to the E4.1 series.
Assembly with new opening bars
Another special feature of the E4Q is its opening bars, explains the manufacturer. These can be opened and closed completely without tools. There are two recesses on the top of the bar for the fingers, with which the locking hooks can be easily pulled open. Unlocked on both sides, the opening bar can be removed upwards with little effort. This makes it easy to open and close the chain, even in a guide trough, and speeds up the filling of the e-chain by up to 40 percent. Another advantage: thanks to its innovative design, the new opening bar has significantly higher pull-out forces when locked than comparable e-chains.
Additional noise damping
The design also makes the chain very quiet in motion. However, if the user requires additional noise damping, Igus has integrated an optional system in the inner horizontal stop for the E4Q. This consists of two connected balls that dampen the impact during the radius and stretch stop. The balls are made of a new noise-optimized and soft material that further reduces the noise level without limiting the stability of the stops. as
