Abstract:
1. A lift system for lifting a vehicle tire attached to a vehicle axle comprising: a carriage assembly including a shaft assembly and a carriage section, the carriage section having a centerline, a top rail, a bottom rail, a connecting member, a first lift pad assembly and a second lift pad assembly, the top and bottom rails extending generally parallel to each other, the connecting member rigidly coupling the top and bottom rails to one another and defining an opening, the first and second lift pad assemblies being cooperatively supported by and shiftable relative to the top and bottom rails, the first lift pad assembly and the second lift pad assembly being operably connected to the shaft assembly on respective sides of the centerline, the shaft assembly comprising a threaded shaft and a leverage component, the threaded shaft extending through the opening in the connecting member, the leverage component presenting a polygonal outer surface to which a wrench can be attached, the shaft assembly being configured to translate rotational movement of the leverage component to synchronous movement of the lift pad assemblies; a column mechanism slideably coupled to the carriage assembly; and a base member attached to a bottom portion of the column mechanism, the base member including lateral support members for providing forward support for the column mechanism and carriage assembly.
