The spreader's design can vary, ranging from conventional single-boom spreaders to more modified two-conveyor compact spreaders. The main parts of a spreader usually come in four signature parts. The first is the signature receiving boom with or without a support crawler track. The second is the main

The overburden is then delivered to the discharge boom, which transfers the cut earth to another machine for transfer it to the central collection area where the material will be sorted. Then the remains of the overburden will be transported to the spreader which then scatters the overburden at the

body superstructure itself. The third is the sub-structure with crawler tracks. And the fourth and final being the discharge boom itself. The discharge boom can be fixed, liftable or slewable and is determined by specific operational requirements.

Spreaders therefore are incredibly large ground vehicles, often approaching the sizes of large bucket-wheel excavators in comparison, as some spreaders have capacities range up to 20,000 m³/h, with discharge boom lengths reaching 195m.
172:, the purpose of the spreader is to receive overburden from the haulage conveyor from the sorting area and dump it in an orderly and efficient manner, whereas a Stacker simply piles bulk material onto a stockpile so that the resulting

161:, BWEs, are used for continuous overburden removal in surface mining applications. They use their cutting wheels to strip away a section of earth (the working block) dictated by the size of the excavator.
