For the driver of the tunnel slag mucking machine, the falling off of the track of the tunnel slag mucking machine is a common problem. For the tunnel slag mucking machine， it is inevitable that the crawler chain occasionally falls off, because the tunnel slag mucking machine generally works in the latest side of tunnel excavation, and the broken stones are relatively hard. If it encounters water seepage and sharp rock stratum again, the crawler will fall off when it enters the soil or stones.
When we say "chain drop", we mean that the track is separated from the track composed of four wheels, commonly known as "chain drop", which is the last scene that the driver of the tunnel slag raking machine wants to see.
In fact, in addition to the above reasons, the factors of operators are also very important. If the driver of the tunnel slag crawler mucking loader encounters a turn during operation, he needs to pay special attention. Once there is a preliminary sign of "chain falling" on the track, the equipment should be stopped. On the other hand, this phenomenon often occurs, which may indicate that the machine itself has a problem and needs to be repaired.
