Loaders are construction machines used for foundation digging, carrying, filling, laying and loading works. They are used in works such as foundation excavation, road construction, excavation of mild soils, excavation of various minerals from mines and loading them onto conveying machines and soil surface cleaning.

Loaders are available in two types: tracked or wheeled. Tracked loaders are mostly preferred for foundation excavation and in areas where wheeled loaders are unable to operate. They are also used in carrying and loading tasks. They can easily operate in narrow spaces with high efficiency as they contact a broader area on the surface. Wheeled loaders are used for loading and carrying loosened materials and in laying works. Their functionality can be increased using various attachments. For example, they are used with forklift blades in marble quarries and for carrying and loading tasks in mines.
