Mobile hydraulic dock ramp is the auxiliary device for cargo handlings used in conjunction with forklift. Without the need of external power supply, artificial hydraulic power only can easily realize height adjustment. Cable chain with adjustable length is used to hook the vehicle, so that the dock ramp and the vehicle can always fit closely even if shift occurs. Wheels are equipped with solid tires, which doesn’t need to inflate but is still sturdy and durable. Combined with brake pats, safety operation can be ensured.
