ABSTRACT:
A lift assembly for use in a repair shop or the like. The assembly includes at least one mast extending generally vertically, and a relatively movable component including a lift frame assembly. The lift frame assembly includes at least one longitudinal member and at least one work-engaging member. A vertically movable lifting assembly is also provided, which includes a movable element. The lift frame is movably secured to the mast by at least one guide assembly which moves substantially vertically along the track of said mast. The mast includes a portion with a slight curve or straight section inclined in the direction away from said fork leg while the curved or other mast allows free but confined movement of said guide assembly as said lift frame travels vertically throughout a range of vertical positions.
