Durable Rear Suspension Hydraulic Mining Equipment Damping Cylinder

Product Description

Product Description

The suspension system is designed to disperse the impact generated by the transportation road surface and loading,extend the frame life, and make driving more comfortable.

The front suspension is pre-set with a kingpin caster angle and a front wheel camber angle. The front suspension cylinder is installed on the frame and plays the role of a steering kingpin when turning, with good maneuverability and less maintenance work.

The rear suspension can swing with the axle and is used to absorb bending and twisting stresses generated on uneven and rough transport road surfaces, so that the stress is not transmitted to the main frame.
