The evolution of the igus® rol e-chain®

igus rol e-chains shown in fast-forward mode over the last 20 years

 The roller energy chain has been the tried-and-tested energy supply for long travels for about 20 years. Besides the successful design that distinguishes all of our linear energy chain systems, stainless steel rollers are added, which upgrade the energy chain to energy supply for heavy-duty applications. As the energy chain rolls and does not glide, it runs quietly and with low vibration. Wear is significantly lower than for designs without rollers, and the power needed for movement is also lower by as much as 57%.

10x longer service life for rol e-chains

More than 20 years of continuous improvement of the igus rol e-chains for long travels and less drive force

The evolution of the rol e-chain
Rol e-chain in crane systems 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.
HD rol e-chain in STS cranes 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.
P4 rol e-chain in crane systems 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.

2018 - the expansion

P4.1 rol e-chain The smart rol e-chain P4.1 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). Worldwide for STS crane systems, ASC cranes etc.

Comparison of how rol e-chains evolved

E400R series

E400R series

1999

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.
 

4040RHD series

4040RHD series

2004

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.

System P4

System P4

2008

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.

2018

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 the i.Sense condition monitoring system 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.
