Compact winches

Compact winches from Liebherr allow the optimum utilisation of the installation space due to their compact construction and integrated transmission gear units. The installation dimensions and the required transmission ratio can be matched at any time.

Compact winches have proven their outstanding capabilities not only in mobile and maritime cranes but also in construction and crawler cranes. Liebherr compact winches are characterised by low rope wear due to their mechanically-worked rope grooving and special grooving. The optimum toothing design also has a positive effect on service life, quiet running, efficiency and noise damping.

Here too, Liebherr's state-of-the-art production methods set the standard for quality and service life.
