ABSTRACT:
A door lifting apparatus includes a frame and a lift mechanism. The lift mechanism includes a slide assembly and a lever assembly. The slide assembly includes a vertical bar, a door support beam supporting a plurality of door holders, and a horizontal bar that are movable together vertically up and down relative to the frame as the lever assembly is moved between a lifted position, an intermediate position, and a lowered position. The vertical bar is associated with a cam plate secured to the frame such that the vertical bar, and the door support beam and door secured thereto, pivots as the lever assembly is moved between the lifted and the lower position.
