Our Tongmyung gear motor is a travel motor designed for crawler machines such as excavators,drilling machines,cranes etc. The motor is a case-rotation,high-torque motor which can be installed inside the crawler by connecting sprocket with motor case.
features
Piston motor has a variable displacement(two speed) swash plate and incorporates a brake valve and a mechanical brake needed for travelling. TM motor with planetary gear reducer offers outstanding features. Hydraulically balanced piston motor ensures reliable changeover of the displacement by external pilot control(1.5~2:1 speed ratio). The motor offers speed control and braking with minimum shock with a built-in double counterbalance valve and shock less relief valve.(These valves are not necessary for a closed circuit.) The mechanical brake is a negative. The brake is automatically activated or released when the stop or starts. The case rotation type gear reducer has improved durability and reliability because of its simple and equally loaded design in addition to high-precision machine parts. The motor used heavy duty bearings to ensure long life. An efficient floating seals also prevent dust and water form entering into the motor.
Piston motor has a swash plate and incorporates a mechanical brake needed for slewing. Hydraulically balanced motor ensures high-pressure and high-performance for a long time. Relief valve with shock-absorb function and make-up valve are appropriately integrated to shorten total length. Parking brake and swing reactionless valve are equipped as standard.
