The winter of 2021 comes early, and the temperature usually drops around February. But this year's cooling has been advanced by nearly two months. Even so, we still need to work hard at our posts. And because of the special circumstances at the beginning of this year, many places have stopped work, and more projects are piled up in the second half of the year. At the end of the year, it is necessary to work overtime to catch up with the projects. However, because of the low weather, the clamshell telescopic arm of the excavator will not catch fire in many cases, and many inexperienced masters will stop work because of this. In fact, some reasons can be found through self-investigation, and some minor problems can be solved by themselves without stopping work. The clamshell telescopic arm of the excavator cannot catch fire? It may be caused by several reasons.

We can check the battery problem first. In many cases, these machines fail to catch fire because the battery is out of order. In winter, the battery is also a part that is very prone to problems. Affected by temperature, the battery pole part is easier to oxidize, and once the battery is oxidized, the power supply voltage will be insufficient. Therefore, the battery can be checked first when the clamshell telescopic arm of the excavator fails to catch fire.

If no problems are found after the inspection, we can check the excavator's clamshell telescopic arm starter circuit. If the circuit is not smooth, it will also cause fire failure. Among them, the relay plays a huge role, so we mainly check it. It has more than one part, there are two parts, battery relay and safety relay, you can pay attention to it when you check it.

In addition to checking the above two major problems, you can also pay attention to the fuel problem, because the mismatched fuel will also cause the fire to fail. Do you know the reasons why the telescopic arm of the excavator cannot catch fire?
