The Hoister is a very important facility to send operators and materials into and out of underground mines. Safe and reliable operation of hoister is directly associated with the safety of workers and stable production. The Hoister Automatic Control System is able to monitor spindles, hoisting speed and speed-limiting devices in a real time manner, and automatically detect overload, under-voltage operation and braking torque during the operation; meanwhile, auxiliary system control at the hydraulic stations is also allowed via advanced detectors and optimized control mode in order to ensure stable operation of the hoisters. The hoisters are protected and the early alarm is generated instantly in case of faults or abnormal conditions. The safety of hoisters, workers and materials are therefore guaranteed.
