Abstract: A hydraulically operated side dump railroad car that operates by utilizing high pressure hydraulic fluid from delivered by a pneumatic to hydraulic converter pump located on the railroad car. On the railroad dump car, the hydraulic fluid is pumped from a hydraulic fluid reservoir to the hydraulic ram assembly of the car, without the use of an accumulator for storing pressurized hydraulic fluid. On the other hand, an existing railroad dump car having existing pneumatic equipment can easily retrofitted with the hydraulic system of the present invention with the use of standard train air brake piston and cylinders.

Abstract: The rail-type conveyor system contains self propelling container trucks which circulate between stations and are provided with unlockable unloading device. Each of the stations is termed with at least one stopping point and have a receiving device for accepting the material conveyed. Each stopping point contains a section of rail corresponding to the length of the container truck, with rail parts which engage laterally in a C-shape around the tracks wheels of the container truck. The rail section is mounted so as to be pivotable about a pivot axis in order to unload the container truck on one longitudinal side and is pivotable towards the unloading side.

Abstract: A car for transporting a ladle of hot metal and charging the metal to a furnace, commonly a BOP or Q-BOP used in steelmaking. The car includes a transversely movable trolley which carries a tiltable support for a ladle. Tilting of the ladle is independent of transverse movement of the trolley. Thus the car can be positioned adjacent the furnace, and the ladle moved tranversely and tilted to dump its contents into the furnace even though the furnace itself is not tilted to a precise position.

Abstract: A coke quenching car is disclosed wherein the hopper is pivotally mounted to a superstructure continuation of the car frame, at points on both ends of the hopper adjacent to its top side which faces the coke side of a coke oven. A means for pivoting the top of the hopper upwards and towards the coke side of the coke oven is included. A discharge gate is attached to the bottom side of the hopper running the length of the hopper and hinged to the lower edge of the hopper side which faces the coke side of the coke oven. As the car is spotted at the coke wharf, the means for lifting pivots the hopper upward, aligning the discharge gate with the coke wharf; the gate is then swung downward to form a chute to the coke wharf. The contents of the hopper descend the inclined plane thus emptying the coke quench car.
