ABSTRACT:
The present invention is a forklift attachment device which automatically secures to the tongs of a forklift when the tongs are raised. The present invention functions to prevent a forklift load from becoming dislodged prematurely. The operative portion of the present invention is a pair of elastomer locking brakes which are positioned along the tongs of the forklift. The forks are inserted into the device. As the load is moved upwardly, levers attached to the locking brakes fall downwardly causing the locking brakes to move into operative engagement with the forks. When the load is returned to a position on the floor, the levers are returned to the starting position causing the locking brakes to release the attachment from the forks.
