GWH500D

A large diesel-hydraulic winch, which consists of two parts:  a power unit and the drum. The power unit comprises a diesel engine with a power of 550 hp, which achieves a trac- tive power of 500 kN on the drum (empty drum). This very powerful winch is primarily used as securing winch, when heavy machinery such as excavators need to work in steep slopes.

The heavy winch consists of a mooring system that retains the wire rope permanently under the same tension and avoids sudden movements of the heavy construction machine work- ing in inconvenient positions. The operator of the excavator working in the slope is able to control the winch via remote control. He can lift or lower the wire rope directly from the machine cabin.

Securing winches of GANTNER have many technical fea- tures, which enable safe and reliable operation. Among oth- ers, a grooved drum system as well as a winding device for the steel cable are used. Additionally, the winch disposes of a double braking system with disc brakes (safety brakes) act- ing directly on the drum and a multiple disk brake (operation brake) guarantee reliable safety.
