The small loader is an earth-rock construction machine widely used in road, railway, construction, hydropower, port, mining and other construction projects. It is mainly used for shovel loading bulk materials such as soil, sand, lime, coal, etc. Ore, hard soil, etc. are used for light shovel. Different auxiliary work devices can be used for loading and unloading of bulldozers, lifting and other materials such as wood. In the construction of roads, especially in high-grade roads, loaders are used for the filling and excavation of subgrade works, asphalt mixing materials and aggregate and loading of cement concrete yards. In addition, you can carry out operations such as pushing soil, leveling the ground, and pulling other machinery. Because the loader has the advantages of fast operation speed, high efficiency, good maneuverability and light operation, it has become one of the main types of earth and stone construction in engineering construction.
