travel drive hydraulic motor are a high torque and high efficiency, EP travel motor specifically designed for crawler machines. The drive motor could be customized to fit the customer’s requirements with many different ratios and displacements obtainable.

Features

The piston motor includes a variable displacement (2-speed) swash plate and incorporates a brake valve and mechanical brake. Coupled with a case-rotation type planetary equipment reducer, the EP drive motor offers the following outstanding features:

– Hydraulically balanced piston electric motor ensures high-pressure high-performance procedure.

– An offset-type 2-quickness design ensures reliable changeover of the displacement by an external pilot control (quickness ratios of between 1.5:1 and 2:1)

– The motor offers an integral dual counterbalance valve and shockless crossover alleviation valve, providing acceleration control and braking with minimal shock.

– The mechanical brake is a negative brake associated with the counterbalance valve. The brake is definitely instantly activated or released when the vehicle stops or starts.

– The case-rotation type gear reducer has improved toughness and reliability due to high precision parts and an equally-loaded design.

– The hydraulic motor uses heavy duty bearings to ensure extended life. Floating seals also prevent dust or water from entering into the motor.
