The shaft hoisting system forms the nerve center of a mine. If there is a problem, the entire operation of the mine comes to a standstill. The mine hoist system consists of the brakes, a hydraulic system, and industrial PLC for optimal automation and safety.
The electro-hydraulic systems from GS Global Resources (GSGR) are designed to meet the various international design and safety requirements of this application. Independent of load and load direction, the braking control system ensures safe winch operation. The required braking force is electronically controlled by means of either a proportional or pressure servo-valve, which is done by at least two independent closed-loop controls. As an option, one additional closed-loop control may be integrated as a reserve. GSGR has integrated directly into the customer’s global supply chain with system sub-assembly and test, prior to delivery to the mine installation.
