Heavy duty rol e-chain® P4HD.56R

For maximum service life with optimised design
The new heavy-duty roller chain fulfils all the requirements that apply to container cranes of the next generation and beyond.
Ever longer distances, higher dynamics, short load cycles, zero failures: That, in a nutshell, is what manufacturers of ship-to-shore container cranes demand for energy chain on crane bridges. The new P4HD.56R fulfils these requirements - with maximum cost-effectiveness.

"Chains for cranes®" next level:
We want 15 years of service life for e-chain systems - on every crane. This is our development goal and can also be found in the specifications for the new P4HD family. New standards in container shipping demand more and more from the energy chains used on STS cranes. Cable carrier specialist igus® presents the new generation of extremely durable profile roller e-chain® - the P4HD.56R - developed specifically for these new challenges.

Additional feature: predictive maintenance with smart plastics

In the latest expansion stage of the igus® e-chain® rollers, the service life is once again significantly increased by the use of maintenance-free tribopolymer plain bearings in the connection of the e-chain link. The new P4HD can optionally be equipped with smart monitoring sensors. This sends a signal to the igus® i.Cee:plus communication module when a defined wear limit is reached, which is used to plan the maintenance of the roller chain in advance. The sensor is integrated into a standard side part of the chain, which does not lead to any restrictions on the usable inner width.

The revolution of the rol e-chain

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%.
