Experts say that under normal circumstances, small excavator products will not cause fires due to normal repairs. In special cases, long-term neglect, maintenance and repair are not timely. Improper operation of the driver, unauthorized electrical system modification, arson and other reasons are the main causes of "spontaneous" or other fire accidents.
According to the statistics of insurance companies, small excavator fire accidents mostly occur near the diesel engine tank or engine, as well as oil pipe leakage caused by fire, improper electrical system conversion, short circuit, etc. The proportion of accidents caused by improper use of fuses is very high. Although the possibility is small, once it occurs, the economic loss of the mini excavator equipment valued at more than one million US dollars is very large.
Therefore, prevention and control are particularly important for this kind of fire accident. Experts suggest that the best way to prevent small excavator spontaneous combustion accidents is to regularly inspect and maintain small excavators to prevent such problems from occurring. First check the engine, hydraulic and electrical systems to see if there is leakage or aging. Clean the engine system in time to ensure the engine inside and outside. In addition, it is necessary to strengthen self-service operators. Many small excavators are not equipped with fire extinguishers. When an accident occurs, the operator cannot save lives. Equipped with firefighting equipment such as dry powder fire extinguishers, it is inspected once a year at a local firefighting equipment store.
When climbing uphill, please pay attention to:
1. Check the slope angle to see if it is within the functional range of the excavator. If the slope is too steep, shake the material from the upper part of the slope to the lower part to reduce the slope.
2. Remove large rocks. When climbing on a steep slope, rocks can also cause the track to slide, which in turn causes the excavator to move forward.
3. When climbing a slope, please lower the center of gravity of the vehicle as much as possible, extend the arm to the head, and keep the bottom of the bucket and the slope at 90 degrees to prevent the bottom of the excavator from sliding into the excavator. Inside the excavator. Bottom.
4. Sometimes you will encounter a loose arm with the excavator climbing, and the excavator can slide down. In order to deal with this situation, the weight of the small excavator can be like this: dig the shovel as deep as possible, press the power, when the arm receives the head, do not spread it, let him tilt, small excavator, fireproof materials move down along the track, and the small excavator forms a pile behind the track. Don't underestimate this pile of small things, which can put the excavator down forever. When staying at the bottom of the bucket and excavator without sliding down, slowly move the arm to the head, and it should be tied in front. The deeper the better.
