1. According to the driving mode, there are two types of excavators: internal combustion engine-driven excavators and electric-driven excavators. Among them, electric excavators are mainly Used in plateau anoxic and underground mines and other flammable and explosive places. And ordinary ground engineering does not need to use force Driven, because he received the influence of the power reserve, the work duration is not strong and inconvenient; 2. According to different operation methods, excavators can be divided into crawler excavators and wheel excavators. Wheeled excavators are not very common See, it is more used in road construction. If it is deep excavation, reclamation and the like, crawler excavators will be used, no Difficulty walking; 3. According to the bucket, excavators can be divided into front shovel excavators and backhoe excavators. Front shovel excavators are mostly used for excavating ground The material above the surface, the backhoe excavator is mostly used to excavate the material below the surface. This also depends on whether you want to dig deep or shallow. Need to choose.

Excavators, also known as excavating machinery, also known as backhoes, use buckets to excavate materials higher or lower than the bearing surface, and load them into transport Vehicles or earth-moving machinery unloaded into stockyards. Common excavator structures include, power unit, working device, slewing mechanism, steering mechanism, transmission mechanism, walking mechanism and auxiliary facilities, etc. From the appearance, the excavator consists of three parts: the working device, the upper turntable, and the traveling mechanism. Depending on its structure and use, it can Divided into: crawler type, tire type, walking type, full hydraulic, semi hydraulic, full rotary, non full rotary, general purpose, special purpose Type, articulated, telescopic arm and other types.

An excavator is a common earth excavation machine in the engineering field. Its main job is to dig material above or below the floor surface with a bucket and load it into a transport vehicle or a stockyard. It can be roughly divided into the following categories: 1. backhoe excavator The backhoe is our most common and most commonly used type of excavator. It can be used for excavation below the floor of the shutdown working surface, and it is not easy to excavate the part above the shutdown working surface. Basic operation methods include: excavation at ditch end and ditch side, straight line, curve excavation, excavation at a certain angle, ultra-deep trench excavation, etc. 2. Front Shovel Excavator The characteristic of the shovel action form of the front shovel is "move forward and cut soil upward". The excavation force of the shovel is relatively large, and it can excavate above the shutdown surface, but cannot excavate the part below the shutdown working surface. It should be applied to dry foundation pits with an excavation height of more than 2m, but up and down ramps must be set. The main shovel bucket is larger than similar backhoe excavators, and it can excavate the first to third types of soil with a water content of no more than 27%. The entire excavation and transportation can be completed with the unloading truck, and it can also excavate large dry foundation pits and level them. mound. According to different transport vehicles and excavation routes, there are different excavation and unloading methods. 3. Dragline Excavator Dragline is also called cable shovel excavator. Its excavation features are: "retreat downward, cut soil by self-weight". It is used for the excavation of Class I and II soils below the floor of the shutdown operation face. When working, the bucket is thrown out by inertial force, and the excavation is relatively far away, and the excavation radius and excavation depth are relatively large, but it is not as flexible and accurate as the backhoe. It is especially suitable for large and deep foundation pit excavation or underwater excavation. 4. grab shovel excavator The grab shovel is also called grab excavator. Its excavation is characterized by "straight up and down, self-weight cutting". It is suitable for the excavation of Class I and II soils below sea level on the floor of the shutdown operation surface. It is often used for the excavation of foundation pits and caissons with soft soil, especially for excavation of deep and narrow foundation pits and dredging of old channels. And water silt excavation, etc., or used for loading loose materials such as gravel, sand, grain, etc. in the seaport, and loading ore, wood chips, wood, etc. in the wood storage yard.

1. Digging ditches Excavators can help people dig ditches and bury pipes, ditches and channels, it's all possible! 2. Digging building foundations Excavators are used to build houses and foundations on construction sites! 3. Can dig fish ponds, shrimp ponds Many other fish and shrimp breeders will use excavators to dig ponds! 4. Can be used to demolish houses Many abandoned houses, old houses are no longer in use and need excavators to break down and demolish them! 5. Excavators can be used as cranes Many places need to transport large objects over short distances, and when it is inconvenient to use a crane, the excavator will be used instead! 6. Can also be used to repair slopes, slope protection In many places, excavators are used to brush the slopes when repairing river banks! The excavator is still quite a lot of uses, you know there are other uses?

The model is 35, that is, the bucket capacity of 3.5 tons is about 0.11 cubic meters. The model is 60, that is, the bucket capacity of 6 tons is about 0.3 cubic meters. The model is 120, that is, the bucket capacity of 12 tons is about 0.5 cubic meters. The model is 160, that is, the bucket capacity of 16 tons is about 0.65 cubic meters. The model is 200, that is, the 20-ton bucket capacity is about 0.8 cubic meters. The model is 220, that is, the bucket capacity of 22 tons is about 1.1 cubic meters. The model is 240, that is, the 24-ton bucket capacity is about 1.2 cubic meters. The model is 270, that is, the 27-ton bucket capacity is about 1.5 cubic meters. The model is 300, that is, the bucket capacity of 30 tons is about 1.6 cubic meters. The model is 400, that is, the bucket capacity of 40 tons is about 1.9 cubic meters. The model is 450, that is, the 45-ton bucket capacity is about 2.1 cubic meters. The above generally refers to the different models of various brands of excavators for natural excavation and stacking. PC200-8, PC stands for Komatsu excavator series 200 stands for 20-ton class, -8 stands for the algebra of innovation. Carter 306, 3 represents the Carter excavator series, 06 represents the 6-ton class, and the new generation is represented by ABCD.

Loaders are generally seen in seaports and logistics centers, mainly for loading and unloading containers. The grader is used to level the road, remove snow, bulldoze, loosen the soil, etc. The excavator is a common construction machinery, mainly used for digging soil, loading, demolition, digging, gravel and so on. Forklifts are mainly used to shovel soil and snow. The scope of loading is similar to that of excavators, but the operating conditions are limited and the efficiency is higher than that of excavators. Forklifts cannot operate in places with soft soil and steep ditches. Generally, forklifts are wheeled. style. Bulldozers are mainly used for dozing, leveling, and loosening, so in many developed places, you can see excavators and bulldozers working with each other, and the efficiency is very high. Scrapers, as the name suggests, are shoveling and transporting soil. Scrapers generally shovel soil in places with a lot of soil and put it in their "belly", and then go up to 500 meters to 2000 meters to unload the soil and put it on the soil where it is needed. The place. Loader is a self-propelled loading and unloading machine that loads bulk materials into vehicles or other equipment. The loader can also perform light excavation work, and can also perform operations such as bulldozing, lifting, loading and unloading wood and steel pipes by replacing the corresponding working devices. A scraper can be used as a loader, but a loader cannot be used as a scraper. Bulldozer A tractor-driven machine with a wide, blunt horizontal blade for clearing land, road structures, or similar work.
