The steering system includes the front wheel steering system and the rear axle steering hydraulic system.

The steering system of grader adopts hydraulic steering system, which is mainly composed of steering transmission mechanism, steering hydraulic cylinder, steering control valve and steering hydraulic oil pump.

In addition to the front wheel deflection steering system, liugong loader accessories are also provided with other steering systems to expand the operating range, reduce the turning radius and reduce the lateral force. If there is a rear wheel deflection and the front wheel tilt.

The front rack deflection system can reduce the turning radius of the grader. It is especially suitable for oblique work.

Brake system includes foot brake device and hand brake device.

The foot brake adopts hydraulic open and automatic force - increasing shoe brake. The brake transmission mechanism is double pipeline pneumatic hydraulic type (from the brake main pump into two ways, respectively to the middle and rear wheels). The brake of hand brake is CAM opening and automatic force increasing shoe brake, and the brake transmission mechanism is mechanical.

Gas-liquid integrated driving braking system is composed of gas-liquid driving mechanism and four wheel brakes, which are symmetric self-increasing force type. Air compressor output of compressed air through the oil-water separator, pressure controller, control the system pressure is 0.5 MPa) after the gas reservoir, the ground through the brake pedal and brake valve control mechanism to move in the compressed air driving booster piston, press brake master cylinder brake fluid respectively into four wheel brakes brake wheel cylinder, brake shoe and brake effect.
