This document 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 document is to provide a clear means to identify earth-moving machinery according to its function and design configurations and with secondary classifications according to its operating mass and control operator configuration. Annex A provides a procedure based on the identification structure used by this document to classify the machinery and introduce detailed identifications consistent with the logic implied by the structure. Annex B provides a hierarchy of the operator control configurations for earth-moving machinery.
