This section GB/T 10051 Part 10.

The partial modification using DIN15413. 1983 "means lifting pulley block hook nuts." this section according to DIN15413. 1983 redrafted.

Taking into account China's national conditions, in the use of DIN15413. 1983 when modified, these technical differences are identified in the single vertical line 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 nut type and size, technical requirements, test methods, inspection rules and signs, package.

3 Nuts intensity level

According to the mechanical properties of nuts into five intensity levels, and lifting hooks intensity level matches, see GB/T 10051.1-2010 3 Chapter Table 1.

4 Nut load ratings

At different intensity levels and institutions working level, each nut 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.
