The loader is an earthwork construction machine widely used in construction projects such as roads, railways, construction, hydropower, ports, and mines. It is mainly used to shovel bulk materials such as soil, sand, gravel, lime, coal, etc. It can also be used to load ore.  , hard soil, etc. for light shoveling operations.  By replacing different auxiliary working devices, it 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, loaders can be used for filling and excavation of roadbed projects, aggregate and loading of asphalt mixture and cement mixture soil yards.  In addition, it can also carry out operations such as pushing soil, scraping the ground and pulling other machines.  Because the loader has the advantages of fast operating speed, high efficiency, good maneuverability, and light operation, it has become one of the main types of machines for earth and stone construction in engineering construction.
