Abstract: The present invention is a pallet cart adapted to transport a loaded pallet to a location within a facility and/or transport loose materials from said location. The pallet cart comprises a base frame, a plurality of castor wheels, a first sidewall and a second sidewall. The base frame includes a front frame side, a rear frame side, a hitch, a hitch tongue pivotally extending from the base frame, and a means for coupling the pallet cart to a second pallet cart to form a single extended pallet cart for moving items having an extended length. Each castor wheel is coupled to the base frame and pivotal about an axis extending vertically downward from the base frame. A castor locking mechanism interacts with said means for coupling to prevent a castor wheel from pivoting about its axis when the pallet cart is coupled to a second pallet cart to form an extended pallet cart.

Abstract: The present invention is a motorized shopping cart retriever that includes a controller that attenuates the power provided to the drive system of the retriever to prevent the retriever from being utilized to move an excessively heavy load of shopping carts. By preventing the retriever and carts from being subjected to overloaded conditions, the operational lives of the retriever and carts are maximized. The retriever is also provided with a burst mode that allows the power provided to the drive system to rapidly increase past the normal attenuated level for a brief period of time in order to reduce the time required to accelerate a retriever loaded with carts to a terminal velocity.
