Scope

GB/T 21941-2008 is the English-translated version of 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.

GB/T 21941-2008 — This standard specifies the backhoe hydraulic excavators and backhoe loaders and grab bucket (see Figure 1) that can be dressed approximate capacity of a typical material calibration method.

Calibration is based on the capacity of the inner wall of the bucket tip size and the volume of material piled determined. Calibration bucket capacity is installed in the bucket assembly into a number of materials as simple geometric shapes.

The purpose of this standard is to provide a uniform comparison bucket capacity calibration method. Rather than to determine the actual bucket capacity in a variety of occasions.
