CFRP hybrid cylinder

Hydraulic cylinders with carbon-fibre reinforced plastic (CFRP)

When steel meets CFRP – weight-optimised hydraulic cylinders

Liebherr has taken on the challenge of reducing the weight of machines without having to fundamentally alter equipment design. The aim of these developments is not only to produce a weight-optimised hydraulic cylinder with identical or improved mechanical properties, but also to offer customers economic added value in consideration of overall operating costs. As a result, we have developed hybrid cylinders for a wide range of applications.

Why use CFRP hybrid cylinders?

  • Increased efficiency through increased digging performance and handling capacity
  • Optimised tool-attachment dimensions
  • Lower CO2 emissions during operation
  • Compliance with permissible axle loads
  • Longer booms
  • Interchangeability without fundamental modifications to the machine
  • Tribological properties preserved
  • Reduced cylinder tube expansion during pressure peaks

Manufacturing process

Fiber composite solutions

We offer a material made of carbon and plastic that makes your products durable and robust.

A wide range of applications

  • Earthmoving and mining Earthmoving and mining

    Due to the weight reduction of individual components, larger attachments can be used, thus increasing digging performance. This results in reduced emissions and more efficient working methods.

  • Material handling technology Material handling technology

    Notably under tough working conditions, hybrid cylinders withstand dirt, moisture and loads caused by high speeds.

    Here again, the use of CRP makes it possible to have longer booms and increase load capacities.

  • Crane construction Crane construction

    Following the principle of "higher, faster, further", hybrid cylinder solutions optimise the load capacity, operating heights and speeds. They also help to reduce the overall weight of the machine. This has a positive effect, for example, in achieving road approvals.
