Small loader is a kind of earthwork construction machinery widely used in highway, railway, hydropower, construction, port, mine and other construction projects. It mainly uses small loader. Small loader is used to load and unload bulk materials such as soil, sand, lime and coal. It can also do light shovel excavation for ore and hard soil. Changing different auxiliary working devices can also carry out bulldozing, lifting and loading and unloading of other materials such as wood. In road construction, especially in high-grade highway construction, small loaders are used for filling and excavation of subgrade engineering, aggregate and loading of asphalt mixture and cement concrete stockyard. In addition, it can also push and transport soil, scrape the ground and pull other machinery. Because the small loader has the advantages of fast operation speed, high efficiency, good mobility and light operation, it has become one of the main types of earthwork construction in engineering construction.
