This is Part 9 GB/T 10051 of.

The partial modification using DIN15412-2. 1983 "means lifting pulley block beam." According to this section DIN15412-2. redrafted 1983.

Taking into account China's national conditions, the use DIN15412-2. 1983 when modified, these technical differences identified in it a single vertical line They were involved in the margins, given the technical reasons for differences and their list in Appendix A for reference.

For ease of use, this section also made the following editorial changes.

--- "This standard" be replaced by "this section";

--- With a decimal point "." Instead of a comma as the decimal point "." Appendix A of this section is an informative annex.

This part is proposed by China Machinery Industry Federation.

This part of the National Standardization Technical Committee crane (SAC/TC227) centralized.

This section is responsible for drafting unit. Taiyuan Heavy Machinery Group Co., Ltd.

Participated in the drafting of this section. Beijing Materials Handling Design and Research Institute.

1 Scope

This section GB/T 10051 specifies the hook beam type and size, technical requirements, test methods and inspection rules.

3 Beam intensity level

Mechanical Properties of beam intensity is divided into five grades, that matches your crampon a high intensity level, see GB/T 10051.1-

2010 Chapter 3 in Table 1.

4 Beam load ratings

At different intensity levels and institutions working level, each beam to withstand the rated load (starting weight) should be matched with the hook, and its value GB/T 10051.1-2010 Chapter 4 listed in Table hook hook No. 2 from the same weight.
