摘要： A vehicle ramp is shown housing a platform having an upper surface adapted to support the wheel of a vehicle, a generally vertical leg having an upper end supporting the platform rearward portion and an inclined ramp adapted to support a forward portion of the platform and to permit a vehicle wheel to move up to the platform. The inclined ramp includes a longitudinal axis and having opposite sides, a lower end adapted to engage the ground, and including a blade for engaging the supporting surface as a vehicle wheel engages the lower end of the inclined ramp and applies a downward force on the lower end and so as to prevent movement of the vehicle ramp away from the wheel as the wheel moves up the inclined ramp, the blade being an integral portion of the lower end of the inclined ramp. The ramp also includes brace members for providing rigidity and which are conveniently removably joined at their opposite ends to the leg and the inclined ramp.
