Designed for Crawler Excavator,has two speed control and mechanical brake ,combined with a planetary gear reducer.
It is a travel motor designed for track drive machine,such as Crawler Excavator,Crawler Drilling Machine, DTH Drill,Directional Drilling Machine ,Crawler Bucket Loader, Crawler Generator Car etc.
The motor is a case-rotation,high-torque motor which can be installed inside the crawler by connecting sprocket with motor case.
Piston motor has a two speed swash plate and incorporates a mechanical brake,combined with a case rotation type planetary gear reducer offers the following outstanding features.
Hydraulically balanced piston motor ensures high-pressure,high-performance operation.
Two speed design ensures relaible changeover of the displacement by external pilot control(1.5~2:1 speed ratio).
The motor offers speed control and brakeing with minimum shock with built-in double counterbalance valve and shockless relief valve.
The mechanical brake is a negative brake linked with the counterbalance valve.The brake is automatically actived or released when the machine starts or stops.
The case rotation type gear reducer has improved durability and reliability because of its simple and equally loaded designed.
The motor uses heavy duty bearing to ensure long operating life.An efficient floating seals also prevent dust or water from into the motor.
