Hydro-mechanical system: Fast telescoping with rope pull technology

Liebherr mobile cranes are controlled precisely using intelligent technology. The LICCON computer system is at the heart of all this. Liebherr designs and produces the software and hardware for the mobile crane control in-house. Our specialists continue to work on the development of the control's architecture to meet the ever growing demands of the market.

We use a hydro-mechanical telescoping system for our mobile cranes whose telescopic boom consists of the pivot section and a maximum of three telescoping parts. The integral rope pull technology makes the telescopic boom particularly simple and quick to extend to the required length

Telescopic boom can be extended as required

The rope pull technology enables the telescopic boom to be extended easily and quickly to any length. The hydro-mechanical telescoping system uses a single-stage, double-action hydraulic cylinder. This extends and retracts telescope 1. Telescopes 2 and 3 are telescoped by ropes.

High lifting capacities

  • High lifting capacities both with full ballast and also with part ballast
  • Oval boom section for great lateral stability
  • High telescoping lifting capacities
