ABSTRACT:
Overhead crane particularly useful in the iron and steel industry for handling rolled material. The crane is provided with a load crab equipped with a circular rail on which there rotates another crab provided with mechanisms which by means of wire ropes operate the means for lifting/lowering, orienting and tilting the load beam which is provided with C-shaped claws. All these wire ropes are inclined thereby providing a positive means for preventing the oscillation of the load. A special arrangement of the runs of the wire ropes and of the rope drums and pulleys ensure that the operations of load lifting and lowering, loading and unloading, and orienting operations are under accurate control.
