LED SignalWarning Device System

In small and medium size mines, the tunnel isusually long and narrow. Therefore, it is difficult for small machine operatorsto timely find miners working in the front as they drive through the aisle.This may result in serious accidents. In order to avoid this, we at GOLDEN WIN THREE have developed two security alarm systems formines.
1. Battery warning device: when a mine car is coming,miners just need to gently pull the cable between the battery case, and the warningsystem will give an alarm immediately and the red light begins to twinkle atthe same time. Hence, the operators could easily know there are people in thefront and thus slow down the car.
2. Electronic warning device: Inaddition to providing alarm function, it enables person in each sub-case pointand person in main case point to talk over the telephone.
