If the excavator is trapped and cannot rescue itself, it can only request rescue. When waiting for rescue, it is necessary to observe whether the trapped excavator is flooded. If not, take preventive measures. If the rescue time is relatively long, we are mainly worried about sudden rainstorm and other situations. In this way, the excavator is easy to get water. This will not only increase the difficulty of rescue, but also damage the excavator. After the excavator is towed up, it needs to be cleaned up. After the temperature of the excavator drops, wash it with a high-pressure water gun.
