 Theory
 
There are two ways to brake the swing motor: parking mechanical brake and hydraulic brake. The parking mechanical brake is installed inside the motor and mainly consists of a spring, a brake piston and a brake friction plate. Pp solenoid valve lock state mechanical brake control:
The input oil at the motor slack port Pp is pilot pressure oil and is controlled by the rotary lock solenoid valve. When the solenoid valve is locked, the Pp port pressure is released, and under the action of the brake spring force, the brake piston tightens the brake friction plate to realize the parking mechanical braking function.
When the solenoid valve is opened, the pilot pressure oil enters the brake oil chamber through the solenoid valve, opens the brake piston, and the mechanical brake is opened. Rotation can be achieved by manipulating the rotation.
Hydraulic brake control: Stop the rotary operation, the rotary valve returns to the neutral position and blocks the inlet and outlet oil circuits of the rotary motor, generating a large back pressure on the return oil circuit to achieve braking.
