P&H
Potentiometer for P&H trolley motor brake
This potentiometer 981E718 functions as a position and speed feedback sensor for the trolley motor brake system on P&H machinery. It provides an electrical signal proportional to the mechanical position of the trolley to ensure accurate control during horizontal load movement.

The potentiometer serves as an electronic control device designed to monitor the position and speed of the trolley motor brake on P&H equipment. By converting mechanical movement into a proportional electrical signal, it acts as a feedback sensor that allows the crane control system to regulate deceleration and maintain precise positioning of the trolley as it moves along the boom. This feedback loop is necessary for managing the movement of the trolley during lifting operations.
This component is specifically engineered for use in P&H trolley motor brake assemblies. It ensures that the crane control system receives accurate data regarding the trolley's location and velocity, which is required to prevent load oscillation and ensure controlled stopping. The device is designed to interface with the existing electronic systems found on P&H cranes and mining equipment.
Potentiometers in heavy machinery systems function by providing a variable resistance that translates into a specific voltage output based on the physical position of a shaft or slider. This output is interpreted by the machine's controller to adjust motor output or braking force. Maintaining accurate feedback from these sensors is standard practice for ensuring that movement commands are executed correctly and that the machine responds predictably to operator inputs during load handling.
