特别是在土方机械的情况下，重心的位置将取决于安装该项目的任何附件或辅助设备的性质和位置。本标准规定了在任何装载条件或附件位置下确定土方机械（如拖拉机、装载机、翻斗车和平地机）重心坐标的方法。

Particularly in the case of earth-moving machinery, the position of the centre of gravity will depend upon the nature and position of any attachments or ancillary equipment with which the item is fitted. This Standard specifies a method for determining the co-ordinates of the centre of gravity of earth-moving machinery such as tractors, loaders, dumpers and graders in any condition of loading or position of attachments.
