GB/T 21941-2008 in English

《GB/T 21941-2008土方机械 液压挖掘机和挖掘装载机的反铲斗和抓铲斗 容量标定》由TC334（全国土方机械标准化技术委员会）归口，主管部门为中国机械工业联合会。
本标准为首次发布。本标准自实施之日起，JG/T 5038.1-1993《液压挖掘机 反铲斗容量标定》同时废止。 本标准规定了液压挖掘机和挖掘装载机的反铲斗和抓铲斗所能盛装的典型物料容量的近似标定方法。
本标准的目的在于提供一个统一的比较铲斗容量的标定方法，而不是为了在各种使用场合下确定实际铲斗容量。
本标准不适用于机械挖掘机的铲斗。

Scope

This standard specifies the approximate calibration method for the typical material capacity that can be contained by the back bucket and grab bucket (see Figure 1) of hydraulic excavators and backhoe loaders. Capacity calibration is determined according to the size of the inner wall of the bucket and the volume of the material at the tip of the pile. The calibration method of the bucket capacity is to divide the material contained in the bucket into several simple geometric shapes as an aggregate. The purpose of this standard is to provide a uniform calibration method for comparing bucket capacities, not to determine the actual bucket capacity in various usage situations. This note does not apply to buckets of mechanical excavators.
