Product Description
Hydraulic transmission is made up of hydraulic motor, brake, NGW planetary gearbox and valves which according to the request of work. This hydraulic transmission has many advantages: Compact, light, high torque, large transmission ratio, high start efficiency, stability and low noise etc. The output shaft can bear large axial and radial force. It has been widely applied for construction machinery, engineering machinery, metallurgy machinery, ship and deck machinery, petroleum and mine machine. Meanwhile, you can choose suitable kinds of hydraulic motor to assemble to the connecting units.
According to requirement hydraulic transmission can be divided into the following types:
HTEF(R) __Hydraulic rotary with brake
HTEF series__Hydraulic transmission without brake
HTEF(Z)__Hydraulic transmission with brake
YJM(Z)series __Hydraulic motors with brake
YJM(Z) EF series hydraulic motor with mechanical braker
