For around 50 years, igus has been developing energy supply systems that reliably guide cables and hoses and protect them against damage. Whereas, in the beginning, they were almost exclusively products for the mechanical engineering sector, the invention of the rol e-chain more than 20 years ago brought about the breakthrough into other branches of industry.
The technical basis of this are rollers in the e-chain links that enormously reduce the coefficient of friction on long travels when the upper run of the e-chain runs on the lower run. As a result, a saving of up to 57% of the drive energy required to move the energy chain system can be achieved. The noise created is also reduced considerably. Thanks to the design, travels of up to 1,200m and more are possible.

The E400R - the first rol e-chain
The integrated rol e-chain 4040RHD
The first igus rol e-chain in Europe with a travel of 130 metres as the main way of supplying power to a crane system.
Heavy-duty rol e-chain used for an STS crane. The "HD version" of the rol e-chain becomes the standard for STS crane applications and ship loaders/unloaders with long travels and high speeds, worldwide.
As an addition to the rol e-chain product range, the P4 is for applications involving very high speeds (<240 m/min) and installations where noise is a very important factor. Where used: worldwide for STS crane systems, ASC cranes etc.
P4.1 – The latest generation of rol e-chains supersedes the P4 and becomes an endurance runner. In the case of ASC cranes, the P4.1 enables the primary supply of power and data and operates at very high speeds (<300 m/min). Where used: worldwide for STS crane systems, ASC cranes etc.
Compared to previously installed festoon systems, the 5050RHD series e-chain systems® can now reduce the required cable lengths, save installation space and safely and reliably guide all media, such as water and energy. The 5050RHD series is used in the large lignite excavator in the Czech Republic.
Series 5050R energy chains, CFCrane chainflex cables and fibre optic cables are used in ship unloaders at a modern coal-fired power plant in Malaysia. All energy chains are completely equipped with stainless steel guide troughs and withstand weather conditions.
Due to rollers in the e-chain links, the coefficient of friction and therefore the drive energy needed for energy supply systems can be significantly reduced. Especially in the case of long travels of more than 100 metres, this is a decisive factor, which led to the success of the rol e-chains from igus.
In the second development stage of the rol e-chains, the chain was strengthened at all important points. In the case of this "heavy-duty version", the pin/bore connection in particular was enlarged by 100% while the size of the contact surfaces was increased by more than 30%. As a result, the expected service life doubled compared to the preceding series.
The P4 is a new development stage. It is characterised by the fact that it operates with considerably less noise and vibration due to the double-roller design, which increases the service life of the system. Due to
the same-sized pitch of standard links and roller links, the polygon effect was reduced as well.
In the latest development stage of the igus rol e-chains, the use of maintenance-free, tribo-polymer plain bearings in the connection of the e-chain links also considerably lengthens the service life. As an option, they can also be fitted with wear sensors, to reliably predict the expected service life of the system. Compared to the first rol e-chain, the expected service life has been more than trebled.
