A machine for prying cross-members loose from their supporting stringers in damaged wooden pallets. A horizontal bed is provided with a plurality of rollers for ease in handling pallets of varied sizes. A superstructure mounted over the bed carries an elongated horizontally disposed rotatably mounted torque bar. A pair of spaced support arms are secured at one of their ends to the torque bar and at their other ends support a rotatably attached pry plate carrier to which are slidably mounted a plurality of curved pry plates. Locking screws secure the pry plates to the carrier at spaced intervals determined by the dimensions of the pallet being dismantled. A first pneumatic or hydraulic ram is connected between the superstructure and a lever bar secured to the torque bar and serves to raise and lower the pry plate carrier. A second ram is connected between the superstructure and a lever arm secured to the pry plate carrier and serves to rotate the carrier and its attached pry plates after they have been inserted through the spaces between the cross-members nailed to the pallet stringers. A plurality of hold-down beams running the width of the bed restrain the pallet against the upward force exerted by the pry plates. These hold-down beams may be fixed or movable vertically.
