---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):

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:
