Description
The TYW series hydraulic drum brake is a normally open brake with a hydraulic drive and horizontal installation. It is controlled by a foot-operated hydraulic pump and is mainly used for the slewing mechanism of medium and small-sized gantry cranes and tower cranes in industries such as lifting, transportation, metallurgy, mining, ports, docks, and construction machinery. It is equipped with a manual brake device, which allows braking in a non-working state.
