Here’s a guide to setting up lifting points for prefabricated modules

As a critical component in the power industry, the placement of lifting points on prefabricated modules is crucial for their safe transportation and installation. During the lifting process, the selection and placement of lifting points not only affect the stability of the modules but also directly impact the safety of construction personnel. Therefore, this article will provide a detailed discussion of the principles for setting lifting points on prefabricated modules, as well as the calculation methods and safety and reliability considerations.

First, let us examine the principles for setting lifting points on prefabricated modules. The placement of lifting points should adhere to the following principles: First, ensure that the lifting points can evenly distribute the weight of the prefabricated module to avoid excessive stress at any single point, which could cause deformation or damage to the module; second, facilitate the operation of lifting equipment to ensure a smooth and safe lifting process; third, the structural characteristics and equipment layout of the prefabricated module must be taken into account to ensure that the lifting points do not interfere with or damage the equipment inside the module.
       Next, regarding the calculation methods for lifting points on prefabricated modules. When determining the location and number of lifting points, detailed calculations should be performed based on the module’s dimensions, weight, and the layout and load distribution of the equipment inside. First, it is necessary to determine the total weight and center of gravity of the prefabricated module to establish the initial positions of the lifting points. Then, based on the layout of the equipment inside the module and the load distribution, the positions of the lifting points should be fine-tuned to ensure that each lifting point bears the weight of the prefabricated module evenly. Additionally, the lifting capacity and operational range of the hoisting equipment must be considered to ensure a safe and efficient lifting process.
After determining the locations and number of lifting points, the lifting points must be reinforced. Reinforcement methods can be selected based on the prefabricated module’s material and structural characteristics, such as adding steel plates or reinforcing ribs. The purpose of reinforcement is to enhance the load-bearing capacity and stability of the lifting points, ensuring that safety incidents such as detachment or fracture do not occur during the lifting process.

Furthermore, to ensure the safety and reliability of the prefabricated module lifting process, the following points must be observed: First, select appropriate lifting equipment to ensure its lifting capacity and operational range meet the requirements for lifting the prefabricated module; second, develop a detailed lifting plan—including lifting procedures, personnel assignments, and safety measures—to ensure the lifting process proceeds in an orderly manner; third, strengthen on-site supervision to ensure the lifting process complies with safety operating procedures and to promptly identify and address potential safety hazards.
