Scope

"This standard identifies earthmoving machines which are intended for use on unimproved surfaces. The machines are used for moving earth and other materials on projects such as road building@ dams@ open pit excavation@ trenching@ and buildings. Excluded are machines intended for use on improved surfaces such as ""in-plant"" material handling@ highways@ water@ air transport@ and for agricultural purposes. Purpose- This standard sets forth accepted terminology to name and identify properly and uniformly types of earthmoving machines@ and is based upon existing commercial earthmoving machines. Illustrations are used to identify functional characteristics. The parts of the standard are: loaders@ dumpers@ tractor-scrapers@ graders@ tractors@ excavators@ and backhoe loaders. Additional parts on continuous diggers and augers will be developed if and when requested. This terminology strives to establish a name for a basic work machine such that a basic machine is not renamed when it is equipped with an optional attachment. For example@ a ""tractor"" as the basic machine may have a dozer available as normal dealer-installed or manufacturer-installed optional equipment. In this case@ the basic machine still carries the name ""tractor""@ and the equipped with dozer"". As a further illustration of this principle@ herein listed are some common working tool attachments. These are designed with the intention that they can be added (and removed) without modification to the basic machine@ thereby enabling the machine to efficiently perform other work."
