An apparatus nails a plurality of cross members to an underlying stringer to produce a pallet. The carriage moves in a continuous motion without stopping over the cross members until the cross members are nailed to the stringer. The carriage includes at least one nailing gun for driving nails and a hydraulic accumulator mounted on the carriage in hydraulic communication with the at least one nailing gun for supplying hydraulic fluid to provide a force to the nailing gun to nail the cross members to the stringer. The nailing gun may be pivotally secured to the carriage wherein the nailing gun pivots with respect to the carriage while driving a nail into the cross member and the underlying stringer. The nail gun is also positioned into a nail driving position pneumatically and when in the nail driving position the hydraulic cylinder is actuated to drive the nail into the cross member.
