摘要： An improved rail car door closer system is provided wherein the movement of a number of appropriately positioned closer wing plates into contact with a number of open rail car hopper doors, is accomplished with hydraulic cylinders and motors. The system incorporates components that direct both the rotation of the wing closers (around a cylindrical frame so as to position the wing closers in and out of position for door closure), and the translation of the wing closers (along the longitudinal cylindrical frame so as to effect the actual closing of the hopper doors). The system is arranged to close more than one door at a time and in the preferred embodiment includes three simultaneously operated door closer wing structures. The heavy duty cylindrical frame incorporates a number of cylindrical outer segments sized to fit around and on the inner cylindrical frame. The segments are directed to rotate and translate on the inner cylindrical frame. Heavy duty coil springs are used to link the movable outer segments, one to the other, and to serve as force dampening structures during operation of the system. A double acting hydraulic cylinder is arranged to direct the translational movement of the closer wings while a low speed hydraulic motor is used to direct their rotational movement. The system may operate manually through the use of a number of hydraulic valves or may be operated semi-automatically through a programmed sequence of closer wing movements.
