The lift comprises a chassis having a support frame and a power source connected to the support frame. A pivot member rotatably connects to the support frame, wherein the pivot member has a pivot plate and a rod rotatably connected to the pivot plate. A lift frame connects to the rod of the pivot plate, wherein a lift arm rotatably connects to the lift frame. The lift further comprises a pressurized fluid drive operatively connected to the power source and operatively connected to the pivot plate, the lift frame and the lift arm. The fluid drive is configured to reciprocally move the pivot plate, the lift frame and the lift arm such that the lift arm moves in three degrees of movement with respect to the chassis.
