This International Standard gives terms and definitions and an identification structure for classifying earth-moving machinery designed to perform the following operations: — excavation; — loading; — transportation; — drilling, spreading, compacting or trenching of earth, rock and other materials, during work, for example, on roads and dams, in quarries and mines and on building sites. The purpose of this International Standard is to provide a clear means of identifying machines according to their function and design configurations. Annex A provides a procedure based on the identification structure used by this International Standard for classifying the machinery and for introducing detailed identifications consistent with the logic implied by the structure. Annex B provides a hierarchy of the operator control configurations for earth-moving machinery. The Bibliography provides a list of terminology standards for many of the machine families identified in this International Standard. Included in those terminology standards are figures depicting different configurations of the machine types in each machine family.
