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.
Tech up
- Developed for the next generations of STS cranes
- Service life extended again (compared to P41.56R) + 50%
- Everything redesigned: rolling elements, side bands, joining links
- Integration of predictive maintenance sensors possible (i.Sense)
Cost down
- Low maintenance
- Minimised downtime when using i.Cee module (failure always means high costs)
- Retrofitting easy - guide troughs remain identical
- predictive maintenance - optimised with the i.Sense add-on module
Proof
- In-house testing facility: for tests at up to 8m/s over a travel of 400 metres
- 50% longer expected service life compared to the proven P4.1 series
Sustainability
- 57% drive power, saving energy
- Leave your energy or drag chain at the end of its life cycle at igus® chainge Recycling Programme utilise. No matter what manufacturer.
"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.
Triple E-class container ships and the requirements for the energy supply systems of STS cranes
This white paper deals with the following topics, among others:
- Challenge: Cranes for triple E-class container ships
- Requirements for the availability and reliability of cranes
- Comparison of energy and signal supply systems for crane trolleys (festoons, busbar system and energy chain)
- Technological outlook: Rollers e-chain®
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%.

Further products for crane systems
Our energy chain systems have proven their reliability worldwide in ship-to-shore cranes, bulk handling cranes, RTGs, RMGs, Goliath cranes, spreaders and reachstackers. They are low-maintenance, robust, durable and quiet and are considered an alternative to busbar systems, festoon systems and motorised drums.
