摘要： A mining vehicle with an improved tailgate design for raising the tailgate above or lowering the tailgate below the mining vehicle depending on operating conditions. The tailgate is comprised of a tailgate door and at least one side bracket which is coupled to the mining vehicle via a respective pivot point. At least one forward hydraulic cylinder is pivotally coupled at a first end to the at least one side bracket and the second end pivotally coupled to the vehicle at a respective first attachment point. The tailgate is further comprised of at least one pivot point hydraulic cylinder, having a first end pivotally coupled to the tailgate door and a second end coupled to the vehicle, such that the tailgate can be raised above or lowered below the mining vehicle as desired.
