Wheel excavator has many advantages, such as continuous operation, large production capacity, high efficiency, adaptability to complex coal seam selection and mining, large transportation slope, simple operation, convenient maintenance, easy modern management, etc. It is especially suitable for high-efficiency mining operations in large open-pit mines. It is mainly used in stripping topsoil, excavating useful minerals, dumping operations, loading to vehicles or conveyor belts, etc. in open-pit mines applications. Next, let's take a look at the introduction of the 800kg mini excavator.

What is a wheel excavator?
How does the wheel excavator work?
What is the composition of the wheel excavator?
The wheel excavator is a multi-bucket excavator that continuously excavates with a plurality of buckets mounted on the runner at the front end of the boom. It is used for the excavation of a large amount of earthwork, the stripping and excavation of mines, and the loading and unloading of large stockyards. It has high productivity and a large digging force, and can directly dig hard soil. In large buildings, water conservancy projects, and mines, it is often matched with transportation equipment to form a continuous operation line. Wheel excavator is divided into small, medium, large, extra large, and giant by production rate or machine weight. Large or larger wheel excavators have a high digging force and are often used in mining. Wheel excavator is gradually developed based on chain bucket excavator, single bucket excavator, and other mining equipment. It is an ideal multi-bucket excavator in continuous operation equipment and one of the largest complete sets of excavation equipment in the world. The basic technical parameters of a wheel excavator are productivity, bucket wheel diameter, digging height, digging force, and machine weight. The excavator mini digger was initially used for loading and unloading operations, developed rapidly after the mid-20th century, and was widely used in large-scale earthwork and excavation projects. The development trend is to increase the excavation force and develop into giant or micro.
When the wheel excavator excavates the material, the machine does not walk, and it mainly relies on the compound motion formed by the rotation of the bucket wheel at the front end and the rotation of the boom to continuously cut the material and load it into the wheel bucket. When the bucket rotates with the wheel bucket to a certain height, The material falls to the receiving conveyor belt due to the action of gravity and is then unloaded to the unloading conveyor belt through the hopper, loaded into vehicles such as vehicles or conveyors, and transported to the designated location. If the machine moves or the boom descends after a layer of material is excavated, the next layer of material is excavated so that the material is excavated from the top layer by layer. The width is determined by the rotation speed. Generally speaking, the height should not exceed 0.7 times the diameter of the bucket wheel. The walking of the mini excavator small digger is auxiliary, the operation is continuous, the bucket is only used for excavation, and the belt conveyor is used for material conveying.
The wheel excavator consists of a working device, a turntable, and a traveling device. The working device includes a bucket wheel, boom and its suspension device, belt conveyor and unloading device, etc. There are two types of bucket wheel, wheel type, and ball type, the former is used for end face excavation and the latter is used for side excavation. The turntable is equipped with a power device, a transmission operating system, a slewing device, a luffing mechanism, boom support, and ancillary equipment. The drive generally uses electricity, and some small ones also use diesel engines. There are two types of walking devices: crawler type and walking type.
The mini digger excavator performs the excavation operation with the compound motion of the rotation of the bucket wheel and the uniform rotation of the boom with the turntable. The bucket on the bucket wheel cuts the soil and loads the bucket from bottom to top. When the bucket turns to the upper position, the soil is unloaded in the output on a belt conveyor. The excavator does not walk during operation, and the inclination of the boom is adjusted by the luffing mechanism to adapt to the layered excavation operation. Some boom lengths can also be changed. When all the soil in the arc working range of the stop point is excavated, the excavator runs forward for a certain distance and then excavates.
