朔里矿采区阶段提料上山提升设备采用JD-11.4型内齿轮小绞车,为保证下行时不飞车,要求带电下行(发电制动),这就需用QC83-80N 型可逆磁力启动器进行电控。为了保证小绞车行车安全,作业规程规定:小绞车无论在提升或下放物料时,都必须送上红灯,禁止行人通过,红灯灭了,才准行人通过。过去,红灯是司机用另外的开关或按钮进行送停的。然而现场司机有忘送、忘停,造成事故隐患。
Shuoli mining section of the stage material lifting equipment used JD-11.4-type internal gear winch, in order to ensure that the car does not fly down, requiring charged down (power brake), which requires QC83-80N reversible magnetic starter Electric control. In order to ensure the safety of small winches, the operating rules stipulate that small winches must be given a red light, no matter the pedestrian passes or not, and the red light is off before the pedestrian passes. In the past, the red light was the driver using another switch or button to stop. However, drivers have forgotten to forget, stop, causing hidden dangers of accidents.
