Less maintenance, stronger in use

Construction machines have a tough job: they have to operate reliably in every work environment and under all weather conditions. It is the same as anywhere - failures cost money and have to be avoided. We offer components made of high-performance polymers that stand out due to their high durability and long service life. This includes energy chains for cable protection and guidance, e.g. when cables are used for work platforms, telescopic forklifts or drilling machines. The suitable UV and temperature-resistant cables for dynamic continuous movements can be found in our chainflex cable product range. Maintenance-free and lubrication-free plain bearings for heavy-duty applications, e.g. in excavators, wheeled loaders and telescopic forklifts, are used from stock or as custom-made components. For all parts, the service life is predictable, which is a plus for every construction planning project. Around the world, more than 20,000 clients from the construction machine industry trust us.

Benefits of igus products:

  • Maintenance-free and lubrication-free
  • Resistant to dirt
  • Resistant to vibrations
  • Highly resilient
  • Predictable service life
  • UV and weather-resistant
  • Cost-effective

Success stories

High dump bucket, L&K Land- und Kraftfahrzeugtechnik

Excavating and grabbing with an additional degree of freedom

iglidur plain bearings replace composite bearings in the joints of a high dump bucket. They exceed the required service life, require no maintenance, are lighter and about 40 per cent more cost-effective than previous versions.

Tunnel boring machine, Herrenknecht AG

Energy chains withstand vibration and dirt

E4 energy chains that are resistant to vibration and insensitive to dirt are used in a tunnel drilling machine. They are exposed to conceivably harsh environmental conditions in a small installation space. ...


Components for telescopic work platforms and cherry pickers

igus replacement parts designed for guidance, transfer and bearing support on telescopic elevated work platforms, such as energy chains and cables as well as plastic plain bearings, linear bearings or sliding plates meet the stringent requirements for components that are subjected to continuous stress in outdoor applications.


Energy chain configurator

Configure complete energy supply systems for short or long travels as well as for hanging applications. Enter the application and environmental parameters and the configurator "e-chain expert" will suggest suitable solutions for your energy supply.


Tested for vibration, low temperatures, resistance to media and heavy loads

Vibration test: in this test, energy chains are subjected to vibrations between 30 and 60Hz.
Extreme test in the cold chamber: energy chains and cables are tested at temperatures as low as -40°C.
Bentonite test: test of energy chains for their resistance to media. Result: they function perfectly after 100,000 cycles.
Front loader test rig: polymer bearings in a heavy-duty test with a maximum load of 500kg.
