Selection and requirements for lifting equipment used in steel structure installation.

The structural design of steel structures is a holistic problem that requires a comprehensive approach, not just focusing on a single indicator. First, the accuracy of internal forces and displacements must be ensured. Based on this, the stress ratio can be used to simply determine whether the stress results meet the requirements, and then a detailed assessment of the rationality of the results can be performed. For structural components, in addition to strength, other indicators such as stability, deflection, deformation, and slenderness ratio must also be considered. During design, it is crucial to analyze the problem comprehensively and consider all relevant factors, such as the selection of lifting equipment for installation.

 

Steel structure installation should primarily utilize standard lifting equipment such as tower cranes, crawler cranes, and truck cranes. If non-standard equipment is used for lifting, a special plan must be developed and reviewed before implementation. Non-standard equipment mainly refers to the use of winches, hydraulic cylinders, and jacks as lifting equipment.

 

 

When lifting equipment needs to be attached to or supported by the main structure, it must be approved by the original design unit, and its forces must not cause permanent deformation of the original structure. Exceeding the rated lifting capacity of the lifting equipment during steel structure lifting is strictly prohibited.

 

Generally, the height of a steel structure factory building depends on the usage conditions and architectural requirements, and also needs to consider the clearance requirements for crane operation if cranes are used. When designing the steel structure lifting and construction plan, in addition to the above factors, we should also consider reasonable economic efficiency and use lifting equipment of appropriate tonnage.
