With the development trend of modern engineering buildings such as crude oil, chemical plants, and coal mines, as well as buildings such as large-span highway bridges, there are more and more lifting projects for equipment and components, and the methods of lifting components, equipment used, and specific lifting methods are becoming increasingly diverse and complex
For lifting engineering, on the one hand, the mechanical equipment and equipment used for lifting cargo tensioners are generally expensive, resulting in safety accidents and damage, which are all major damages. On the other hand, the goals of lifting engineering are generally all the main and critical equipment or components in new projects, resulting in lifting safety accidents, economic losses, and incalculable economic losses caused by construction delays. Based on the entire process of lifting engineering, a detailed introduction to the key points of safety technical supervision before lifting is provided below for reference only
1. Before lifting, it is necessary to approve the construction design plan prepared by the construction unit for the actual conditions of the lifting equipment, lifting slings, lifting weight of components, lifting half diameter, on-site parts, and other main parameters of the lifting project, and establish the safety technical key and technical measures to ensure safety of the lifting project. Based on the components being lifted, the location and the situation of the site, the lifting project should be analyzed. It should be stipulated that the construction design plan prepared by the construction enterprise has a clear safety protection key plan or countermeasure, ensuring that the safety technical measures have feasibility analysis in the plan.
2. Strict verification of the selection of steel reinforcement tensioner models, crane positions, foundation and other lifting engineering technical measures is the main guarantee for reliable stability of technical measures. Therefore, the key to safety technology engineering supervision is also to approve the technical stability of the lifting project. The key is to determine the model selection of the lifting equipment and the selection of equipment and equipment such as lifting slings by reviewing the force and structural mechanics calculation of the equipment and components for lifting. Based on the lifting equipment and the net weight of the lifted equipment and components, determine whether the foundation of the lifting equipment is a solution and the actual solutions
3. The organizational measures, layout of lifting space (crane parts, placement of equipment components), assembly and disassembly of cranes in the lifting plan are also key factors for the approval of safety technical engineering supervision before lifting
