  • Patent number: 4966517
    Abstract: An apparatus is designed to rotate a vehicle by ninety degrees for repair of the under carriage of the vehicle and other parts accessible from the bottom. The preferred vehicle is a forklift, and a mast support is provided to be secured to the mast of the forklift. Wheel supports are provided which may be rotated out of engagement with the wheels when the vehicle is vertical to allow unobstructed access to the vehicle. Removable support bars may be used in place of the wheel supports to engage the bottom of the vehicle during rotation. The apparatus sits on a flat floor and does not require approach ramps or the like. The apparatus may be moved to any location and is symmetrical so that it may be placed against a wall on the left or right by a simple interchange of parts. A jib is provided which may be used to hoist heavy parts of the vehicle.

  • Patent number: 4134501
    Abstract: A lift for servicing the running gear and underside of a vehicle, embodies a pair of parallel channel-shaped base beams connected at their ends by extensible members. A pair of vehicle-receiving platforms of channel-shape are hinged to and lie directly above and parallel to the base beams. The base channels open upwardly, while the platform channels open downwardly. Within the channels and between each pair of base and platform beams is pivotally mounted a folded lift unit including a fluid pressure applying device having a piston and rod, a lever mechanism including three folded arms and links, a booster fluid pressure device and a safety mechanism. Actuation of the lift units causes them to unfold and elevate the platform beams with a vehicle loaded thereon, to an elevated and inclined position.
