ABSTRACT:
A service lift stand apparatus includes a lift assembly, a mast assembly, a base assembly and a ramp assembly. The lift assembly includes a pair of lift arms which each mount a pair of individual support pads. The lift assembly is supported by the mast assembly with the lift arms extending in a cantilever fashion from the mast assembly for movement between a lowered loading and unloading position and a raised servicing position. The lift arms and support pads are adjustable to match different vehicle wheelbase sizes. The base assembly includes an adjustable platform, and the ramp assembly is adjustable and can be located at either end of the platform for driving the vehicle onto the apparatus at either end thereof. Also, the ramp assembly is located in spaced relation to the platform to accommodate nesting of the lift arms and support pads along the opposite platform ends in the lowered loading and unloading position of the lift assembly. The apparatus also includes a wheel barrier assembly for retaining the vehicle on the lift assembly, and a follower assembly for preventing accidental descent of the lift assembly.
