<p>VEHICLE HOIST A vehicle hoist is provided with improved access to the vehicle in which a ramp section is raised on two vertical posts. The ramp section constitutes a first lifting mechanism and a second lifting mechanism is provided in the ramp section deck to raise the vehicle wheels clear to permit work to be done without removing the vehicle. The relative attitude between the ramp section and the vertical posts, i.e., vertical to horizontal, is maintained by a guide means which travels through a limited arc relative to a horizontal axis to react with the vertical columns and maintain the ramp section horizontal. The vertical posts are also restrained from inward movement by spacer rollers on the ramp section which engage the adjacent faces of the vertical columns.</p> |
