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 travels and unsupported, side-mounted applications. This is made possible by the famous "undercut" design between the two chain links. Compressive strength and rigidity are increased, which provides for greater resistance to wet and rough weather conditions. Special roller chain links make E4/4 into a true specialist for long travel distances. The undercut design also allows excellent ESD performance. The chain links always fit tightly together; only when there is good contact between them it is possible for electricity to flow (please note: this only applies to the special conductive material igumid ESD and does not apply to the standard series included 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 is standing here, extracting delivered coal piles and transporting them to the boiler via conveyor belts. It moves along a rail system over a distance of 700 metres. And the power cables follow it - inserted in a heavy-duty rol e-chain® of the 5050RHD series from igus® (5050RHD.30.300.S10.0) and thus protected from flying coal.
