ABSTRACT:
A lift apparatus includes a base frame having a pair of ground engaging caster assemblies and a pair of horizontally extending divergent legs each having an inner end attached to the base frame and an outer end with a roller attached thereto, the casters and the rollers permitting the lift apparatus to roll across the ground surface. A dual parallelogram linkage includes a pair of the posts attached to the base frame and is attached to vehicle support arms. An actuator is connected between the linkage and the base frame and is manually actuated to selectively raise and lower the vehicle support arms between a lowered position for engaging and disengaging from a vehicle and a fully raised position.
