ABSTRACT:
The apparatus includes a frame having two vertical legs and a horizontal bridge beam. A chain hoist is mounted on an eye nut on the bridge beam. A primary chain and a secondary chain are suspended from the chain hoist. The secondary chain is connected to an object to be lifted. The secondary chain may be connected to C-shaped clamps, which are placed on the edge of the object to be lifted. After the object has been broken free of the ground, the frame may be tilted about a horizontal axis, to pull the object from the ground.
