本文件提供了用于分类用于执行以下操作的土方机械的词汇和识别结构: —？发掘 —？加载； —？运输 —？在施工期间，例如在道路和大坝、采石场和矿山以及建筑工地上，钻取、摊铺、压实或挖沟土方、岩石和其他材料。 本文件的目的是提供一种明确的方法，根据其功能和设计配置识别土方机械，包括根据其工作质量和控制操作员配置进行的额外分类。 附件A提供了一个基于本文件所用标识结构的程序，用于对机械进行分类，并介绍与结构所隐含逻辑一致的详细标识。 附件B提供了土方机械操作员控制配置的层次结构。

This document provides vocabulary 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 which can include additional 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.
