Electric cable shovel for transporting bulk materials.

摘要

"Automatic rope shovel for the transport of bulk materials", characterized in that the rope pick-up drum is connected by means of a chain drive with a clutch acting as a Fºttinger type hydrodynamic brake, and being particularly suitable for the transport of building materials, when they are placed in a distributor in the facilities where the concrete is prepared, in which the component materials accumulate forming a slope, arranged in piles that form sectors around the distributor, for which has been mounted on it, an arm that, having a free end, is articulated on a rotating chassis and that to fully start the shovel receptacle, the traction cable has been laid, as the recoil cable, provided with windings independent of each other, which are wrapped on two separate drums, which have been mounted on an axis driven by a motor and located in a chassis, in which the drum that collects the traction cable, is fixedly connected to said shaft, rotating freely, but can be connected by means of a clutch that resists the moment of rotation, with the shaft , and in which the free movement of the drum for lowering the blade receptacle can be delayed by means of the hydrodynamic brake at the indicated beginning.
