E4/4 system
The E4.1 predecessor for long travels and side-mounted applications
The E4/4 system is used in two areas: For extremely long travel distances and for unsupported applications lying on their side. The famous "rear grip" between two chain links makes this possible. Compressive forces and rigidity are increased, which increases resistance to wet and harsh weather conditions. Special roller chain links make E4/4 a true specialist for long travel distances. The undercut design - the simple attachment in the grooves provided - also enables the outstanding ESD performance. The chain links are always close together, as current can flow when they come into contact with each other (please note: this only applies to the special conductive material igumid® ESD and does not apply to the standard series in this catalogue).

Real-world examples
Bucket wheel excavator
India, in the state of Punjab, in the village of Banawala: a huge bucket-wheel excavator stands here, extracting the delivered piles of coal and transporting them via conveyor belt towards the boiler. It moves along a rail system over a distance of 700 metres. And the power cables follow it - inserted in a heavy-duty roller chain from the 5050RHD series from igus® (5050RHD.30.300.S10.0) and thus protected from flying coal.
