| Summary | 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. This standard does not apply to mechanical excavator bucket. |
