This tire lift caddy has a rectangular frame supported on casters, and a pair of rollers mounted therein across the frame. The rollers are guided along a respective pair of inclined slots in the side of the frame. A threaded rod extends along a length of the frame. A pair of push bar assemblies are mounted to the threaded rod and to the axles of said rollers for moving the rollers in unison along the slots upon a rotation of the threaded rod. The threaded rod has a left-hand thread thereon and a cylindrical handle on a working end thereof. The cylindrical handle can be worked with the palm of the hand, or finely adjusted with the fingers to raise the rollers to a desired level. The rollers have a central groove in surfaces thereof for nesting the threaded rod therein when the rollers are in their lowermost positions. |
