Radial piston variable motors

Radial piston motors are used in caterpillar drives of dragline excavators, cranes, winches and ground drilling equipment. Radial piston motors are capable of producing high torques at very low speeds, down to half a revolution per minute. Therefore, radial piston motors are also referred to as Low Speed High Torque (LSHT) motors.

The pistons (or plungers) of a radial piston motor form a star-like shape and are perpendicularly connected to the shaft. The rectilinear motion of the pistons is transformed into a rotating movement by the eccentric shaft.

Multi-stroke piston motors increase displacement substantially because each piston carries out multiple strokes per revolution of the shaft. Hence, a hydraulic multi-stroke piston motor produces high operating torques.
