A loader is a versatile earthmoving machinery widely used in road, railway, construction, hydropower, port, and mining projects. It is primarily used for loading materials such as soil, sand, lime, coal, and other loose materials. It can also perform light excavation tasks on ore and hard soil. By attaching different auxiliary devices, it can be used for tasks like pushing soil, lifting, and unloading materials such as wood.

On road construction, especially on expressways, loaders are used for earthwork operations such as filling and excavation, as well as for handling aggregates and materials at asphalt and cement concrete mixing yards. Additionally, they can perform tasks like pushing soil, leveling ground, and towing other machinery. Due to their fast operation speed, high efficiency, good mobility, and ease of operation, loaders have become one of the main types of machinery for earthmoving and rock excavation in construction projects.
