Dual Hydraulic Disk Brake System for Hot Metal Charging Crane in an Iron Works

摘要

The present invention relates to a dual hydraulic disc brake system for a steel mill crane, in a steel mill crane having a drum for hoisting a wire rope used for lifting work, the drum being installed on both sides of a disk of the drum to rotate the drum by brake lining. A plurality of calipers for stopping the plurality of calipers, a plurality of hydraulic units for supplying hydraulic pressure to the calipers to press the brake lining to the disc side, a hydraulic pipe connecting the caliper and the hydraulic unit, and a front end of the caliper to the hydraulic pipe. It includes a shutoff valve that is installed to block the hydraulic supply to each of the caliper. In the present invention, by applying a hydraulic unit of a dual structure by configuring the system to operate with one other hydraulic unit even when one hydraulic unit failure can achieve an effect that greatly improved the ability to cope operation.
