Small loader is a kind of widely used in earthwork construction machinery of highway and railway, hydropower, construction, ports, mines and other construction projects, it is mainly used for loading and unloading of soil, sand, lime, coal and other bulk materials, can also be used as a mild shovel of ore and hard soil digging etc.. Different auxiliary working equipment can also be used for lifting, lifting and other materials such as wood loading and unloading operations.

In addition, the soil can be pushed, scraping the ground and traction other machinery and other operations. As the small loader has the advantages of fast operation, high efficiency, good mobility, easy operation and so on, it has become one of the main types of earthwork construction in engineering construction.
