PMC-R 2.0 Roof Support Control
The intrinsically safe Cat® PMC-R 2.0 control units are specifically designed to be used on shearer or plow faces to provide high levels of longwall automation. Each roof support is equipped with one PMC-R 2.0 control unit and solenoid driver to operate the in-shield hydraulic functions and peripheral components, such as sensors for cylinder pressure and stroke length, shield inclination and personnel proximity detection. The PMC-R 2.0 unit controls and displays all functions of a roof support and serves as the interface between operator and machine (HMI).
