Loaders are primarily used for scooping, loading, unloading, and handling loose materials such as soil and stones, and can also perform light excavation tasks on rocks and hard soil. By swapping to different attachments, they can also be used for tasks like pushing, lifting, and unloading other materials. In highway construction, they are mainly used for the filling and excavation of subgrade projects, as well as for loading aggregates in asphalt and cement concrete plants. Due to their fast operation speed, good mobility, and ease of operation, they have rapidly developed and become the main machinery for earth and stone construction.
