Abstract
An apparatus for rescuing an automatic guided vehicle comprises a pallet lift including a lift body, wheels for a rolling upon a supporting surface, and first and second elongate lift rails extending horizontally forward from the lift body and set apart a distance to allow the rails to embrace an automatic guided vehicle therebetween. First and second lifting tabs extend inward from each of the lift rails and include upper support surfaces for lifting the base of an automatic guided vehicle which lie beneath support surfaces of the first and second rail by a distance greater than a distance and the base of the automatic guided vehicle lies beneath a wheel of a cart being carried piggyback by the automatic guided vehicle. A method of rescuing an automatic guided vehicle and a piggyback cart from an elevator includes rolling the pallet lift onto the elevator to a position in which the automatic guided vehicle is between the lift rails and the rails are beneath the wheels of the cart. The rails are then lifted to an elevation at which the wheels are supported by an upper surface of the rails and the pallet lift is rolled off the elevator to transport the cart from the elevator and fro…
