ABSTRACT:
The invention comprises a panel lift apparatus for detachably mounting to a conventional drywall lifter for raising a drywall panel, from immediately adjacent the ground, to the lifting arms of the lifter for transfer of the panel to the lifting arms of the lifter. The apparatus has a main frame for attachment to the main frame of the lifter, with a pivotally mounted channel member pivotally mounted for pivoting adjacent the lifter for storage, and pivoted to a spaced away position for operation. The channel member has a lifting plate for movement down along the channel to a position immediately adjacent the ground for receiving a drywall panel thereon. A cable is attached to the lifting plate at its one end and a drum at its other end and a wheel is mounted to the drum to rotate the drum to wind the cable onto the drum to raise the lifting plate in the channel to thereby raise the panel thereon to the lifting arms of the lifter. The lifting plate its pivotally mounted to its slidable movement in the channel to pivot away from the channel for easier transfer of the panel from the lifting plate to the supporting arms of the lifter.
