Small loader is a kind of earth and stone construction machinery widely used in roads, railways, hydropower, buildings, ports, mines and other construction projects. It is mainly used for loading and unloading bulk materials such as soil, sand, lime, coal, etc. And hard soil for light digging operations. Different auxiliary working devices can also be used for loading and unloading of bulldozing, lifting and other materials such as wood. In roads, especially in the construction of high-grade highways, small loaders are used for the filling and excavation of subgrade engineering, the aggregate and loading of asphalt mixes and cement concrete yards. In addition, it can also carry soil, level the ground, and tow other machinery. Because the small 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.
