ABSTRACT:
A method and system is presented for ensuring that a latch securing a ramp to a pallet is properly aligned and seated before a product can be offloaded from the pallet and down the ramp. The system uses a latching system that has a pallet-attached base and a ramp-attached mating bracket. The pallet-attached base has two rods. The first rod has a retainer arm that is restricted by the second rod to a vertical position, thus preventing a shipment on the pallet from reaching the ramp. The second rod has a thin portion and a thick portion. The second rod must be laterally moved such that the mating bracket mates only with the thin portion of the rod. This lateral movement moves the second rod away from the first rod's retainer arm, thus allowing the retainer arm to fold down.
