Experts say that in general, small excavator products will not cause the normal repair of a fire. In special circumstances, long-term negligence, maintenance and repair are not timely. Driver's improper operation, unauthorized electrical system correction , Man-made arson and other causes are the main causes of "spontaneous" or other fire incidents.
According to the statistics of insurance companies, small excavator fire incidents mostly occur near diesel fuel tanks or engines, as well as oil pipe leakage caused by fire, improper electrical system conversion, short circuit, etc. The percentage of incidents involving improper use of fuses is very high. Although it is possible It is very small, but once it happens, the economic loss of the value of the micro excavator equipment exceeding one million US dollars is very large.
Therefore, with regard to this kind of fire incident, prevention and prevention are particularly important. Experts suggest that a better way to prevent spontaneous combustion incidents of small excavators is to inspect and maintain small excavators on time to prevent such problems. First check the engine, hydraulic pressure and The electrical system, see if there is leakage or aging. Clean the engine system in time to ensure that the engine is inside and outside. Others, it is necessary to strengthen self-service operators. Many small excavators are not equipped with fire extinguishers. In the event of an accident, the operator cannot save lives. Equipped with For example, fire-fighting equipment such as dry powder fire extinguishers is inspected once a year at the local fire-fighting equipment store.
When going uphill, please note:
1. Check the slope angle to see if it is within the scope of the excavator. Assuming that the slope is too steep, please roll the material from the upper part of the slope to the lower part to reduce the slope.
2. Eradicate large rocks. When climbing on a steep slope, the rocks will also cause the crawler track to slip, which then causes the excavator to move forward.
3. When climbing, please lower the center of gravity of the vehicle as much as possible, extend the arm to the head, and insist on the bottom of the bucket and the slope to be 90 degrees to prevent the bottom of the excavator from sliding into the bottom of the excavator.
4. Sometimes you will encounter a loose arm climbing with the excavator, and the excavator can slide down. For this situation, the weight of the small excavator can be as follows: dig the shovel as deep as possible, press the power, and act as the arm. When you receive the head, do not spread it, let him tilt, small excavators, fireproof materials move down the track, small excavators form a pile behind the track. Don't underestimate this pile of small things, you can excavate The machine will go permanently. When staying at the bottom of the bucket and excavator without sliding down, slowly move the arm to the head and tie it to the front. The deeper the better.
