ABSTRACT:
A pallet jack is disclosed that comprises a left tine, center tine, and a right tine. The center tine is about 2 times the width of each of the left and right tines, though other widths of the center tine can also be implemented. Because the center tine is about twice the width of the left and right tines, two pallets, side-by-side, can be carried simultaneously with only three tines. According to another embodiment of the pallet jack, a portion of the center tine (a right-most portion) and the right tine can have raised areas that enable an operator of the pallet jack to lift a right pallet that sits on the raised areas higher than the left pallet. The left pallet sits on the left tine and center tine without the raised areas (at a lower height). Thus, the operator of the pallet jack can place the left pallet in a first location without disengaging the tines from the right pallet, or without lowering the right pallet all the way to the ground (or a first location surface). Alternatively, the raised areas can be located on the left tine and the left-most portion of the center tine, in which case, the operator of the pallet jack can place the right pallet in a first location without disengaging the tines from the left pallet, or without lowering the left pallet all the way to the ground (or a first location surface).
