LTM Series (400-1400ml/r)

The LTM series low speed high torque hydraulic motors adopt a radial five-piston configuration, delivering large displacement, low-speed operation, and high torque output. This motor is designed for hydraulic drive systems requiring direct drive, allowing working mechanisms to be driven without a reduction gearbox. With excellent low-speed stability, LTM series motors are well suited for heavy-load starting and continuous low-speed operation.
