Small excavators, also known as minitype excavators, have different definitions for small excavators, such as the mainstream of 1~3 ton small excavators in countries where loaders are best-selling (such as Britain, France and Italy). In countries where excavating loaders are not widely used, such as Germany, they are more inclined to use 4~6 tonnes of 名媛直播. However, almost all countries tend to buy larger equipment. From this, we draw a conclusion that the small excavator is defined as a 1~6 ton loader can be called a small excavator, of which 2.7 to 3 ton grade 名媛直播 account for a large proportion, because they can easily be transferred to a general transport vehicle. The field. The small excavator benefits from the small posture, and it has become an ideal equipment for the application of earthwork in urban areas.

It is generally made up of power device, transmission device, walking device and working device. Principle: excavating the material above or below the bearing surface with a bucket and loading the earthmoving machinery into the transport vehicle or unloading to the stockyard. Use bucket to shovel and lift off objects or minerals from the working face and transport them to the self propelled mining machinery unloaded at the unloading place. History: the first manual excavator has been in history for more than 130 years. During the period, it has experienced the gradual development of the automatic hydraulic excavator from steam driven excavator to electric drive and internal combustion engine driving rotary excavator and the application of electromechanical hydraulic integration technology.
Due to the application of hydraulic technology, a suspension excavator was equipped with a hydraulic backhoe on the tractor in 1940s. The towed full rotary hydraulic excavator and the crawler type full hydraulic excavator have been developed in the early and middle stages of 1950s. The initial trial production hydraulic excavator is the hydraulic technology using aircraft and machine tools, the lack of hydraulic components suitable for various working conditions of the excavator, the quality of manufacturing is not stable, and the supporting parts are not complete. Since 1960s, hydraulic excavators have entered the stage of popularization and vigorous development, and the number of excavator manufacturers and varieties has increased rapidly, and output has increased rapidly. In the past 1968-1970 years, the output of hydraulic excavators has accounted for 83% of the total output of excavators. At present, the output of hydraulic excavators is close to 100%.
Maintenance instructions

1. clean up the dirt on the surface of the small excavator and check whether there are loose fasteners.
2. check and check whether the level of antifreeze liquid and oil level are normal, check whether the oil quality is normal, check the level of anti freezing oil.
3. if the weather is very cold, the small excavator will be shut down for a long time. Please drain the coolant of the engine. At the same time, in order to prevent battery feeding, the battery must be removed and stored in a warm place.
The engine runs once for a period of 4. intervals. If the liquid level and oil level of the antifreeze liquid are lower than the normal oil level, please add it to normal and start again in time. In the cold weather, the key is placed in the preheating position to the preheating lamp (repeated preheating), then the engine is started again. After 5-10 minutes of idle speed, the operation of each cylinder is 5-10 times without load operation, and each time is 5-10MM smaller than the maximum stroke. Finally, the engine speed is the fastest and the operation of each cylinder is 5-10 times. At the same time, the left and right revolutions and the front and rear movements are 3 times. Until the system temperature rises to 50 to 80 degrees, it will work normally and continue to stop the engine after 5-10 minutes.
5. diesel oil should be replaced by -10 to -30 model. This depends on the area where the diesel is located, the more diesel oil is added to the north area, and the diesel filter is replaced. The oil should be replaced by the local oil, the oil filter is replaced, the hydraulic system has the oil leaking place and the time of replacement, and the conditional oil tank should be guaranteed. Temperature.
6. the heat dissipation system should seriously check whether the hose is aging or breaking. If there are any problems, it should be replaced in time, because these places are more prone to problems in winter. If hot water is provided conditionally, the water tank is best heated every day so that it can better start the engine, but we must be careful not to forget to let it go. The reason why anti freeze is not advocated is that it is not easy to start the engine by adding antifreeze in a particularly cold area.
