Less work and lower cost for the maintenance of construction machinery with igus® plastic bearings and energy chains

The performance of igus® polymer products is outstanding whether under vibration, low temperatures, heat or dirt

Construction machinery has to withstand very tough working conditions and needs to work reliably even in bad weather. igus® makes this possible with its energy chains and polymer bearings that are characterised by their outstanding resilience and long service life. The product range includes energy chains for cable protection and guidance, e.g. when cables are used for aerial work platforms, telescopic forklifts, or drilling machines. chainflex® cables that are resistant to UV radiation as well as low temperatures are designed for highly dynamic continuous motion. Maintenance-free and lubrication-free polymer bearings used wherever there are high loads, e.g. in excavators, wheeled loaders and telescopic forklifts. More than 20,000 customers worldwide place their trust in polymer solutions tested under realistic conditions, and in the many years of experience accumulated and built on by igus®.
