Abstract
Safety device for preventing the fall of load-lifting hoppers and the like, commonly known as skips, which ascend and descend via guides, characterized in that, unlike known devices which are operationally complicated and of doubtful efficiency, the present device is simple and totally efficient, to which end it comprises pawls 1 arranged in the direction opposite from that of ascent of the lifting hopper 2 and fixed to a shaft 3 mounted rotatably in said hopper 2 which slides via guides 5, an arm also being fitted to said shaft 3 and urged against the hopper 2 by a spring 15 and being arranged opposite the pawls 1, the entrainment and support cable 6 of the hopper 2 is being applied against a rotary end wheel 9 of said arm 8, tensioning thereof preventing the pawls 1 from being able to apply themselves against the guides 5 and doing so through the action of the spring 15 upon breakage of the cable 6, abutting next on stops 17 which will halt the incipient fall of the hopper 2.
