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.
