Mining Brakes On WPT Power Corporation

The Mining Brake is a spring-applied, air-released design specifically for heavy-duty earthmoving equipment, such as rope shovels and draglines. These brake units feature pneumatic operation, have a variety of torque capacities and pressure settings, and can dissipate large thermal loads. Multiple hub options provide installation flexibility. Optional limit switches and wear indicators are available.
