Lifting machine integrated backup protective equipment (lifting machine backup protection / winch backup protection), according to the mining safety regulations and the MT407 - 1995 ", is strictly in accordance with the requirements of coal mine safety regulations and development and production of backup protection device, the device main role in mining ground lifting machine safety backup protection, it uses imported the embedded computer chip assembly, has the advantages of accurate operation, simple operation, strong anti-interference ability, complete functions, and other characteristics. In mine ground lifting machine safety backup protection by using the modern computer technology to design the function, reliable protection of electronic equipment, improve machine integrated backup protective apparatus and the main function, it uses imported embedded computer chip assembly, has the advantages of accurate operation, simple operation, strong anti-interference ability, complete functions, and other characteristics. (lifting machine backup protection / winch backup protection) lifting machine integrated backup protective equipment functions: indicating the depth, speed display, hook a few accumulated, memory management, overspeed alarm, constant velocity section of the overspeed protection, automatic deceleration, deceleration section protection deep that protect, card skip protection, blocking signal, brake clearance, Mancang, loose rope, roll over protection and fault memory protection. When the power cut, can automatic memory current parameters, so as to improve the reliability and accuracy of monitoring system, is a comprehensive backup device for mine ideal.
