In order to better categorise the new E4.1 e-chain®, igus® compared it to the E4.1 and the E2/000 in the following test. For this purpose, all three energy chains were assessed with regard to their appearance, unsupported length, behaviour when subjected to tensile forces and the resistance of the cross bars. The motion plastics® expert thus proved that the E4.48L combines the strengths of the E4.1 and the E2/000, and is therefore to be categorised as being between the two other chains with regard to its tested characteristics.
