Summary: This standard specifies the loader bucket and shovel volume of material that can be dressed in typical approximate calibration method. Calibration is based on the capacity of the inner wall of the bucket tip size and the volume of material piled determined. Different structural shape of the bucket, the bucket capacity is installed in the bucket of the materials used as aggregates into several simple geometric shapes to be calculated. 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.

Foreword

This revised standard adopts ISO 7546. 1983 "moving machinery - Loaders and shovel bucket capacity Calibration" (in English). This standard is based on ISO 7546. 1983 re-drafted. This standard is based on the actual application and taking into account China's national conditions, in the use of ISO 7546. 1983 when some modifications. This standard And ISO 7546. 1983 Differences exist as follows. Draft International Standard --- references to references, the latest edition of international standards; --- International standard Chapters 3 and 4 were interchangeable; --- 5.1 to 5.5 of this Article is defined as a suspension segment content to different structural shapes bucket Chapter 3; --- The figure is calculated by the move each respective strip, and increases the number of the formula; --- Formula added Symbol Description Unit; --- 5.2.2 and 5.3.2 added formulas Explanation of symbols; After an increase of 6.2 --- examples. For ease of use, this standard also made the following editorial changes. --- "This International Standard" be replaced by "this standard"; --- Instead of using the decimal point as a decimal point ",". ","; --- Remove the foreword to international standards. Since the implementation of this standard, JB/T 8113-1999 "loader bucket capacity Calibration" and JG/T 5038.2-1995 "hydraulic excavator Excavator bucket capacity scaling n "shall be repealed simultaneously. The standard proposed by China Machinery Industry Federation. This standard by the national earthmoving machinery Standardization Technical Committee (SAC/TC334) centralized. This standard is drafted by. Tianjin Academy of Engineering Machinery, China Machinery Holdings Limited. Participated in the drafting of this standard. LOVOL International Heavy Industry Co., Ltd., Guangxi Liugong Machinery Co., Ltd. Drafters of this standard. Wu Yun Cai, Chen Shu Qiao, Chen Chao, Ma Xilin, Huangjian Bing. This standard was first formulated. Earthmoving machinery Loaders and shovel bucket capacity Calibration

1 Scope

This standard specifies the loader and shovel bucket capacity of materials that can be dressed in typical approximate calibration, calibration capacity is According to the inner wall of the bucket tip size and bulk material volume determined. Different structural shape of the bucket, the bucket capacity is installed in the bucket as aggregate material into a number of simple geometric shapes To perform the calculation. This standard aims to provide a unified comparison bucket capacity calibration method, not in order to determine the various applications Actual bucket capacity.
