The P4.1 e-chain: Merging bearing technology & smart sensors for longer service life

P4.1 smart plastics

New maintenance-free bearings and an intelligent wear sensor ensure a longer service
life in the P4.1 roller chain for cranes and gantries.

 

The line of P4 energy chains has been optimized for greater reliability. With the new P4.1 roller chain, there is a bearing point for pivoting in every chain link connection. These points are integrated with maintenance-free plain bearings, which minimize friction and more than double the expected service life. Container cranes in ports, for example, can achieve a service life of more than 15 years or 20,000+ operating hours.

In addition to the plain bearings, the P4.1 roller chain can be equipped with isense smart sensors. isense smart sensors monitor wear and abnormal operation in energy chains, finding small problems before they become critical failures. Engineers can access the service life data through any software system with the igus® Communication Module (iCOM), so maintenance is reduced to a minimum.

Automated storage and retrieval systems

Modern energy chain technology is enhancing a variety of automated storage and retrieval systems. Beneficial features of the e-chain® for these applications include quick and easy assembly, light weight, and reliability at high speeds and accelerations. The e-chains® are also low cost and very quiet running.


Storage and retrieval machine

Heavy machinery / Plant construction

Energy chains are the most durable solution for guiding and protecting cables and hoses in heavy machinery. Steel mills, oil platforms and other application areas operate reliably when integrated with e-chains®, as the material is corrosion-free withstands temperatures up to +1,562˚F. Long travel distances and angles of rotation up to 900˚ can be achieved.
