What Is a Micro Excavator?

Small excavators are also called small excavators. The definition of small excavators is also different. For example, in countries where excavator loaders are popular (such as the United Kingdom, France, and Italy), small excavator products of 1 to 3 tons are mainstream. In countries where the use of backhoe loaders is not very common (such as Germany), it is more inclined to use 4-6 ton-class products. However, almost all countries tend to purchase larger equipment, and we conclude that the definition of a small excavator is that a 1 to 6 ton class backhoe loader can be called a small excavator, of which 2.7 to 3.0 ton products The large proportion is due to the fact that they can be easily transferred using general-purpose transportation vehicles. The small excavator benefits from its small size, and it has become an ideal device for earthwork applications in urban areas.

First, the preheating of the hydraulic device, when the hydraulic oil temperature is low, if the rapid operation will cause damage to the hydraulic device.

1. The small excavator engine runs at medium speed, operates the bucket, and preheats;

2. Lift the machine to rotate the crawler, and preheat the left and right walking motors respectively;

3. Then, raise the engine speed to the maximum, and make the bucket and stick work continuously for 5 minutes;

At the same time, during the warm-up operation, full attention should be paid to the safety of the surrounding environment. When the temperature is low, people's reactions will be relatively slow. Prevent people and objects from being touched during warm-up.

Second, the warm-up of the small excavator engine, the first step in the car, the engine should be started and run at low speed for 5 minutes. At the same time, the following inspections should be performed during the warm-up of the small excavator engine:

1. Whether the oil warning light is off;

2. Whether there is oil or water leakage;

3. Whether the engine sound and exhaust color are normal;

4. Whether the charging indicator is off;

5. Whether all parts of the machine are abnormal.

3. If the small excavator is not used in winter, it should be properly kept and maintained. Only when it is used again, the best performance can be achieved. The specific maintenance measures are as follows:

1. Clean the dirt on the surface of the small excavator and check for loose fasteners.

2. Check whether the antifreeze liquid level and the oil level are normal, check whether the oil quality is normal, and check the antifreeze level of the fuel.

3. If the weather is extremely cold and the small excavator has a long shutdown time, please drain the engine's coolant cleanly. At the same time, in order to prevent the battery from feeding, the battery must be removed and stored in a warm place.

4. Start the engine at an interval. If the antifreeze liquid level and the oil level are lower than the normal oil level, please add it to normal before starting. In cold weather, place the key in the preheating position until the preheating light is on (repeated preheating multiple times), then restart the engine, and operate the cylinder 5-10 times without load after idling for 5-10 minutes, each time the maximum The stroke is 5-10MM smaller. Finally, make the engine speed up to 5-10 times for each cylinder, and rotate left and right and back and forth for 3 times at the same time. Normal operation can be performed until the system temperature rises to 5080 degrees. Continue to make all working devices stop the engine after 5-10 minutes.

5. Diesel should be changed to -10 to -30 models, depending on the region. The more northward, you must add more-diesel, and also change the diesel filter, the oil should be replaced with the local Chemical oil, oil filter is also replaced, the hydraulic system should be replaced in a timely manner where there is oil leakage, conditional fuel tank should be well insulated.

6. The cooling system should carefully check whether the hose is aging and broken. If there is a problem, replace it in time because these places are more prone to problems in winter. If it is possible to provide hot water, it is best to heat the water tank every day so that the engine can be started better, but you must be careful not to forget to drain the water. The reason why antifreeze is not recommended is because it is more difficult to start the engine in particularly cold areas.

Throughout the various papers supporting the substantial growth of small excavators, the main arguments are:

1 'The country continues to develop, especially the prosperity of the real estate, and the construction of everywhere is causing an increase in the demand for excavators

2'Proportion of total number of small excavators and large excavators in developed countries

The 3 'small excavator has low consumption and flexibility compared to the large excavator, including convenient transportation (ordinary agricultural vehicles can), and can work in narrow areas.

4 'Rural construction needs.

5's price advantage compared to big dig.

Above, judging whether there is a significant increase in 5-10 years depends on the national policy and the degree of recognition of the Chinese market.
