Foreword

This standard was drafted in accordance with the rules given in GB/T 1:1-2009: This standard replaces GB/T 30024-2013 "Crane Metal Structure Capability Verification", compared with GB/T 30024-2013, mainly The technical changes are as follows: ---Modified normative references (see Chapter 2, Chapter 2 of the:2013 edition); ---Modified some of the main symbols used in this standard (see Table 1 in Chapter 3, Table 1 in Chapter 3 of the:2013 edition); ---Modified the additional verification formula for the weld link of the plane state stress, that is, the coefficient on the right side of the equal sign is changed from 1:1 to 1:0 (see equation (32), The:2013 version of the formula (32)]; ---Added elastic stability verification (see Chapter 7): The translation method used in this standard is equivalent to ISO 20332:2016 "Crane Metal Structure Proficiency Verification": The Chinese documents that have a consistent correspondence with the international documents cited in this standard are as follows: ---GB/T 229-2007 Charpy pendulum impact test method for metallic materials (ISO 148-1:2006, MOD) ---GB/T 1800:2-2020 Product Geometric Technical Specification (GPS) Linear Dimension Tolerance ISO Code System Part 2: Standard tolerance zone code and limit deviation table of holes and shafts (ISO 286-2:2010, MOD) ---GB/T 3098:1-2010 Mechanical properties of fasteners bolts, screws and studs (ISO 898-1:2009, MOD) ---GB/T 3098:17-2000 Fastener mechanical performance inspection hydrogen embrittlement preload test parallel bearing surface method (idt ISO 15330:1999) ---GB/T 5267:1-2002 Fastener plating layer (ISO 4042:1999, IDT) ---GB/T 15706-2012 General Principles of Machinery Safety Design Risk Assessment and Risk Reduction (ISO 12100:2010, IDT) ---GB/T 17505-2016 General technical requirements for delivery of steel and steel products (ISO 404:2013, MOD) ---GB/T 19349-2012 Metal and other inorganic coatings to reduce the risk of hydrogen embrittlement steel pretreatment (ISO 9587: 2007, IDT) ---GB/T 19418-2003 Guidelines for the quality classification of steel arc welded joint defects (ISO 5817:1992, IDT) ---GB/T 20863:1-2007 Classification of lifting appliances Part 1: General rules (ISO 4301-1:1986, IDT) ---GB/T 22437 (all parts) crane load and load combination design principles [ISO 8686 (all parts)] This standard was proposed by China Machinery Industry Federation: This standard is under the jurisdiction of the National Hoisting Machinery Standardization Technical Committee (SAC/TC227): Drafting organizations of this standard: Taiyuan University of Science and Technology, Beijing Crane and Transportation Machinery Design and Research Institute Co:, Ltd:, Zoomlion Heavy Industry Co:, Ltd:, Zhengzhou Xindafang Heavy Industry Technology Co:, Ltd:, Henan Branch of Beijing Crane and Conveying Machinery Design and Research Institute Co:, Ltd:, Tianjin Port Co:, Ltd: Company, CSSC Ninth Design and Research Institute Engineering Co:, Ltd:, Euroneck Heavy Industries Co:, Ltd:, Henan Mining Crane Co:, Ltd:, Jiangxi Hoisting Machinery Factory Co:, Ltd:, Ningxia Tiandi Benniu Yinqi Equipment Co:, Ltd:, Newkelun (Xinxiang) Crane Co:, Ltd:, Qingdao Haixi Heavy Industry Machinery Co:, Ltd:, Henan Dafang Heavy Machinery Co:, Ltd:, Guangzhou Special Mechanical and Electrical Equipment Inspection and Research Institute, Foshan Nanhai District Special Equipment Equipment Association, Nanjing Switchgear Co:, Ltd: The main drafters of this standard: Xu Gening, Zhang Pei, Dong Qing, Qi Qisong, Ren Huili, Chen Hao, Fu Ling, Xiao Yang, Zhu Jing, Yuan Xiufeng, Li Feng, Guo Zhiqiang, Yao Tianfu, Cui Peng, Han Zhongcheng, Teng Yun, Zhang Changli, Liang Jianxin, Wu Yiguo, Liu Yuxin: The previous versions of the standard replaced by this standard are as follows: ---GB/T 30024-2013: Crane metal structure proficiency verification

1 Scope

Based on the limit state method, this standard specifies the general conditions, requirements, methods and parameters for the proficiency test of crane metal structures: The value is used in conjunction with the applicable part of the load and load combination in ISO 8686: This standard is universal and applies to all types of cranes: For special cranes, other standards may specify their capabilities Specific requirements for verification: The ability verification is carried out through theoretical verification calculations and/or tests, aiming to use the established strength limits (such as yield limit, fatigue, brittle fracture) Crack) to avoid the hazards associated with structural performance: According to ISO 8686-1, proficiency verification calculations can adopt two methods: the limit state method of the partial safety factor and the overall safety factor: Allowable stress method: Although the validity of the allowable stress method is not excluded, this standard only relates to the limit state method: This standard does not include proficiency verification calculations for accessory components (such as railings, stairs, walkways, and driver's cabs): But need to consider these accessory parts The impact of the main structure:
