Owner’s Manual PTV 33/44/55/66 Operation of Liftgate Theory of Operation The rail-type liftgate is designed to transport cargo vertically from the vehicle bed to the ground and vice versa. A hydraulic power unit provides pressure to two vertical cylinders that raise and lower the platform. Activation of a control switch supplies current from a 12-volt battery source to the hydraulic power unit.
