A conveyor belt is a mechanism which is able to transport goods (or people) over a distance. It is made of a band, which is held by a number of wheels. On one side, the belt is used for transport, on the other, it travels back the distance. Conveyor belts are commonly used to transport bulk goods, such as sand or coal.

Luffing of the boom minimises dust by reducing the distance that material such as coal needs to fall to the top of the stockpile. The boom is luffed upwards as the height of the stockpile increases. Some stackers can rotate the boom. This allows a single stacker to form two stockpiles, one on either side of the conveyor.
