Engineering partner for drive systems

Planetary gearboxes and rope winches from Liebherr are orientated around specific applications. Experienced designers work out the right gear solution for each requirement. During the design of drive systems, Liebherr employs state-of-the-art development and calculation methods. We continue to develop components and complete systems further.

High standards in design and manufacture

The integral construction method of Liebherr's gears allows for compact shapes and an optimum power to weight ratio. Well conceived design principles ensure an even load distribution of the individual stages and therefore a high power density.

Using FEM, it is possible to determine the stress curve during meshing of planetary gears

Professional design

During the intricate design of Liebherr gearboxes, our experts rely on progressive simulation and calculation technologies such as the finite element method (FEM).

In the process, Liebherr acquires important knowledge on the load bearing behaviour or gearing safety. This results in constructive adjustments and contributes towards the ongoing optimisation of our products.

Unique vertical integration

Liebherr attaches great importance to high vertical integration while, at the same time, concentrating on the core processes. The resulting linked production and process competencies are the basis for high quality products.

Our production facilities, such as fully automatic gear production lines or state-of-the-art induction hardening machines are at the cutting edge of technology. They enable not only variable batch sizes but also guarantee consistently high quality.

Reliability on all levels

Liebherr works with renowned classification companies

Liebherr works with renowned classification companies

To assure the high standards, all company processes are orientated around quality in the area of gearboxes and rope winches.

Our drive systems comply with the specifications of various classification organisations such as Det Norske Veritas - Germanischer Lloyd (DNV GL), American Bureau of Shipping (ABS) or Lloyds Register of Shipping (LRS). Moreover, our certified suppliers are also required to comply with quality standards specified by Liebherr.

High quality materials

All torque-conveying gearbox components are made of top-quality case-hardened and tempered steels which are certified to the Liebherr works standard. This goes beyond the conventional industrial standards and includes a 3.2 material certificate in accordance with DIN EN10204.

Liebherr optimised factors such as operation behaviour on own load test benches. We perform lifecycle tests on these as well.

State-of-the-art testing methods

Our calculation engineers rely on load bearing measurements performed using own high frequency pulsation and FZG stress test benches. In this way, we acquire precise configuration results. The calculated material curves are more precise than those from specialist literature and provide even greater accuracy.

Consistent quality management

We document all production and assembly processes in a computer-supported production data acquisition system (BDE system). The central quality management system records all measures relating to production and assembly. This enables comprehensive control, monitoring and subsequent traceability.

Approved quality: certifications

The numerous certifications are testament to Liebherr's high standard of quality. Aside from the usual ISO standards of the quality management system, Liebherr has the following certifications:

Wind industry

Liebherr supplies individual components, as well as the entire system for the rotor blade and yaw adjustment in wind turbines. Systems for the wind industry
