Wheel lift

A jack frame apparatus adapted for lifting and supporting engagement with a vehicle part to facilitate service and/or repair of the vehicle, comprising a horizontal base frame member adapted to be carried on spaced casters for providing mobility of said apparatus;

• a jack frame assembly including a horizontal cross frame member disposed above said base frame member, cooperable relatively slidable guide and leg means extending between said base frame and cross frame members, and means disposed between said base frame and cross frame members for effecting substantially vertical adjustment of the jack frame assembly relative to the base frame member;
• a support frame assembly including a support plate member disposed above the cross frame member of said jack frame assembly and being adapted for vertical adjustment relative thereto for supporting engagement with a vehicle part, one of said jack frame and support frame assemblies having vertical leg means and the other having cooperable vertical guide means for said vertical leg means, and means for effecting relative incremental vertical adjustment between said jack frame and support frame assemblies comprising vertically spaced sets of openings in one of said vertical leg means and cooperable guide means for the selective positioning of locking bars therethrough for engagement with the other of said vertical leg means and cooperable guide means.

A jack frame apparatus adapted for lifting and supporting engagement with a vehicle part to facilitate service and/or repair of the vehicle, comprising a base frame including a cross beam member adapted to be carried on spaced apart casters for providing mobility of said apparatus;

• a jack frame assembly including a cross frame member disposed above said cross beam member, one of said cross beam and cross frame members having guide means secured thereto and the other of said members having cooperable leg means slidably engaging said guide means, means disposed between said cross beam and cross frame members for effecting substantially vertical adjustment of the jack frame assembly relative to the base frame;
• a support frame assembly including a support plate member disposed above the cross frame member of said jack frame assembly and being adapted for vertical adjustment relative thereto for supporting engagement with a vehicle part, vertical guide means on one of said jack frame and support frame assemblies and the other having cooperable vertical leg means slidably engaging said vertical guide means, and manually adjustable, fail-safe, locking means for effecting the selective, incremental, vertical adjustment of the support frame assembly relative to the jack frame assembly comprising vertically spaced sets of openings in at least one of said cooperable vertical means and vertical leg means, and load bearing locking bars positioned in a selected set of openings for locking engagement with the other of said cooperable vertical guide means and vertical leg means.
