PS series hydraulic disc brake system is an integrated product of machine, electricity and liquid. It is an important part of winch. PS series hydraulic disc brake consists of three parts: brake actuating mechanism, hydraulic station and operating platform. They are connected by hydraulic lines. The hydraulic station is the power source, to provide hydraulic power required for actuators; the operating platform is the execution control center of the organization; the executive mechanism is part of the implementation of the brake, which is composed of brake clamp, clamp frame, the brake disc is composed of three parts, wherein the brake caliper is divided into normally open and normally closed safety work clamp pliers two type of brake disc is divided into wind cold, cold water and solid disc three.

The device has four functions as follows: 1, work brake 2, emergency braking 3, parking system 4, roll over / anti-collision protection.

The hydraulic disc brake device mainly consists of three parts, the brake actuating mechanism, the hydraulic station and the operating table.

The brake actuating mechanism mainly includes: work tongs, safety tongs, brake disc and clamp rack four parts.

The work clamp mainly consists of a brake block, a clamp body, a pin shaft, a lever, a supporting rod, a semicircle retaining ring, a pin shaft II, an oil cylinder end cover, a cylinder body, a tension spring, a rear end cover, a pin shaft III, an adjusting nut, and a piston rod.

The safety clamp mainly consists of a brake block, a clamp body, a pin shaft, a lever, a supporting rod, a semicircle retaining ring, a pin shaft, a piston, an oil cylinder end cover, an oil cylinder, a lock nut, an adjusting nut and a pin shaft.

The brake disc is divided into three types according to the structure form: water-cooled, air-cooled and solid brake disc.

The clamp holder is the base of the actuating mechanism, and the work tongs and the safety tongs are all arranged on the base.

The hydraulic station comprises an oil tank component, a pump assembly, a control block assembly, a refueling assembly, an electric control box, etc.
