With electrical protection and interlock device, is to enhance the machine's power systems and braking systems

Hoist control system for hoist high pressure, low driving force braking, the braking force is not driven, the driving force for the drag brake, brake band frequency, etc., and with electrical protection and interlock device, is to enhance the machine power system and the braking system, but also enhance the machine fails to protect the system. Two ore three levels of intake air shaft depth of 765m,  air circuit breaker  tons tub single bicycle cage, calculated to enhance the equipment selection, the final argument  mcb circuit breaker  in charge of the wellbore to mention extract task, the hoist maximum static tension: 200KN, maximum static tension difference: 180KN, motor power 2 × 800KW, the maximum rope speed 7m / s, using the electronic control system, the electronic control system is now in two ore three  electric meter  running into the wind failures are analyzed and explained approach. Electronic control equipment Scope: altitude does not exceed 1200m; ambient temperature not higher than 40 ℃, not lower than -20 ℃; relative temperature does not exceed 85%; around without conductive dust and metal and insulation has damaging effects of the gas;
