Wheel loader is a type of earth moving machinery that is widely used in construction sites, as well as for many other non construction tasks. Wheel loader, as opposed to track loader, has sturdy tires equipped with large, rugged tread that allows for optimum maneuverability. Mini, small, large and super wheel loader; skid steers loader; front loader and backhoe loader are the most common types of wheel loaders.

Wheel loader is a variation on tractors that are designed for more laborious work. The biggest difference between wheel loader and tractor can be seen in their steering systems. Most wheel loaders steering systems use a hydraulically actuated pivot point, sometimes named as articulated wheel loader, which allows the front and rear axle of the wheel loaders to bear more weight than automotive steering systems.
In the front of a wheel loader is a square bucket, called the loader, which is maneuvered by flexible arms. The loader is either a permanent fixture or an attachment secured to either the front or back of the machine. Some wheel loaders, such as a backhoe loader, have a bucket in the front and a backhoe in the rear. This kind of machine is able to dig with the backhoe and remove the unearthed material with the loader.

Wheel loader has the ability to perform four general tasks; scooping, digging, dumping and carrying. They are commonly used for carrying construction materials like bricks, sands or soil, pipes and rock. Wheel loader is also efficient for snow removal in commercial areas. Farms also employ various types of wheel loader for many reasons, including scooping and transporting hay and excavating the land. Mini wheel loaders can be used inside buildings.

Wheel loaders have an advantage over track loaders, because wheel loaders are easier moving on paved roads and other sensitive environments. Track loaders are more suited to tasks that involve digging, because wheel loaders are unable to dig much below the tires without getting stuck. When a task involves transport or shallow excavation, wheel loader is less destructive and therefore more efficient in the long term.
