A loader, also called a bucket loader, front loader, or payloader, is a machine widely used in the construction sector, either for buildings, public works, roads, highways, tunnels, or any activity that requires moving soil or rocks in large volumes, as well as loading and managing waste. 

This machine is composed of a tractor and a shovel, also called a scoop. The tractor can move on tires or chains, while the bucket moves on the articulated arm attached to the machine’s chassis that allows the movement of the shovel.
