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.

Abstract: A pallet clamping device is mounted between forks of a material handling vehicle. The device clamps to a stringer of a pallet using a pair of horizontally moveable jaws. The jaws are resiliently forced toward one another for clamping a stringer so that a clamped pallet will not move off the forks. The jaws are mounted for pivoting and sliding motion relative to mounting pins which, together with links coupling the jaws to a base of the device, tighten jaw closure if a pallet moves away from the forks. The pivoting and sliding motion of the jaws helps align the jaws with pallets not perfectly aligned with the vehicle. Depression of a foot pedal moves the jaws from a closed position to a latched open position for receiving a pallet stringer. The jaws can also be moved to an unlatched open position for receiving a greater width center stringer. Upon release of the operating device from the unlatched open position, the jaws move toward their closed position.
