igus P4.1 roller chain for cranes and gantries

Click2Contact

In order to increase the uptime of crane systems and gantries, igus has combined its core competencies in the areas of plain bearing technology and energy chains. In the P4.1 roller chain for long travels, newly developed tribologically optimised plain bearings ensure lubrication-free mounting of the individual chain links. This significantly prolongs the service life of the energy chain. Optionally, the P4.1 e-chain can be part of the igus predictive maintenance system with a new isense wear sensor.

The design of the P4.1 roller chain significantly increases reliability and availability. There is a bearing point for pivoting in every connection of the chain links. This has now been re-equipped with a maintenance-free tribo-polymer plain bearing, which more than doubles the service life. In this way, container cranes in ports, for example, can now achieve a service life of more than 15 years or 20,000 plus operating hours, with low maintenance and high reliability.

Optionally, the P4.1 can be equipped with smart monitoring sensors, such as a wear sensor for the newly installed plain bearings. From a defined wear limit, this can issue a signal to the igus icom communication module and maintenance can be planned in advance. Depending on the user's requirements, the data of the icom module can be used differently: with a direct integration into the existing software environment and intranet solution for a pure maintenance message or with the connection to the igus data centre for intelligent and dynamic service life prediction.
