The Mechanical Handling and Storing of Material

ENDLESS ROPE AND CHAIN HAULAGE 261 A rope haulage plant of an unusual design is that of the Soc. Anonyme des Hants Fourneaux & Fonderie de Pont-a-Mousson, France. This is for handling 180 tons per hour of iron ore. The most interesting portion is a movable bridge running on a rail track on each side, and commanding the whole of the ore pocket; the position of the bridge can be moved when the haulage plant is in motion. The self-unloading trucks hold 1| tons of ore each, whilst their weight is approximately 1 ton each. The haulage rope (Glinz Patent) is com- pounded from chain and rope, the lengths of rope are about 12 yds. each, and they are coupled to each succeeding length by a short piece of chain. A portion of this compound chain and cable is illustrated in Fig. 384. The trucks are attached to the Fjg. 334. Compound Chain and Cable Haulage Rope, cable chain by the usual “ jockey,” the chain portion being dropped on to this. The cable is endless, and the plan, Fig. 385, shows the same in dotted line, the arrows giving the direction in which it moves. 1 he ore, as it conies from the mine in trucks, is emptied by two tips b into a small hopper, the
