摘要： A machine lift having a base secured to a vehicle floor adjacent the rearward end thereof at one side thereof. A rotatable pedestal is mounted on the base and extends upwardly therefrom. An elongated lift arm, having inner and outer ends, is pivotally secured to the pedestal and extends outwardly therefrom. An elongated linkage, having inner and outer ends, is pivotally connected at its inner end to the pedestal adjacent the lower end thereof and extends outwardly therefrom. The outer ends of the lift arm and linkage are pivotally connected to a frame which extends upwardly from a horizontally disposed support platform. An elongated screw actuator extends between the pedestal and the lift arm for raising and lowering the platform with respect to the vehicle. The platform may be moved from a position wherein it is positioned on the floor of the vehicle adjacent the other side thereof at the rearward end thereof to a position rearwardly of the vehicle which enables the screw actuator to lower the platform onto the ground rearwardly of the vehicle.
