This unit may be used for indurstrial machinery, including for the circular movement of construction  machinery.

The mechanical brake relief valve and the make-up being built in, the circular movement of the motor is very smooth. 

The motor is made compact by arraying the motor, brake and valve in a proper manner.

High capacity and reliability have been realized by optimalizing the motor and the valves.

Mechanical shocks have been minimalized by absorbing changes in pressure and torque which may occur when the motor stops operation.
