The invention comprises a panel lifting apparatus having a U shaped horizontal frame with rollers mounted along the bottom for transporting the frame from place to place. A pair of inclined channels are mounted in spaced relation along the apex of the frame. A pair of hooks having rod like extensions are each mounted on a frame having rollers for rolling along the inclined channels to roll the hooks upward and downward along the inclined channels. A crank and drum are rotatably mounted on one of said channels. A cable has its ends attached to the pair of hooks and an intermediate portion extending through the drum whereby rotation of the drum by the crank in one direction causes the cables to wind in opposite directions on the same drum to wind the ends of the cables upward simultaneously and thereby draw the hooks upward on the channels simultaneously. The channels extend sufficiently downward to be adjacent the frame rollers and the ground that the hooks may be lowered by the crank to immediate adjacency to the ground and are adapted to receive a drywall panel thereon adjacent the ground. The hooks may lift the panel up to a height where they may be transferred onto a panel lifter having an extended height capability.
