The number of lifting points required for a lifting operation depends on a number of factors, including the weight, shape and size of the load, the location of the center of gravity, the method of lifting, and the capacity of the lifting equipment.
Generally, only one lifting point is used for single-point lifting, but there are some seams in this approach because if the lifting point fails or becomes unbalanced, the load may tilt, overturn or fall. Therefore, in many cases, using multiple lifting points for lifting operations is a safer option.
The use of multiple lifting points reduces the risk of lifting equipment failure by better distributing the weight of a heavy load and reducing the load on a single lifting point. Multiple lifting points also provide better stability and prevent the load from tilting or overturning.
The exact number of lifting points required depends on the characteristics of the heavy load and the lifting method. Before lifting operations are carried out, adequate safety assessment and planning should be carried out, and relevant safety standards and operational procedures should be followed.
Analysis of lifting point requirements for lifting operations
The number of lifting points for lifting operation is determined according to the shape, size, quality and other factors of the lifting object. Generally speaking, four lifting points are generally used for square objects, and the positions of these four lifting points should be chosen on the symmetrical positions of the four sides. For the installation of machinery and equipment, in order to achieve higher precision requirements, you can also use auxiliary lifting points with simple spreader to adjust the required position of the machine parts lifting method.
Lifting operations are divided into first-level lifting operations (m > 100t).second-level lifting operations (40t<m<100t) and third-level lifting operations(m < 40t) according to the quality of the lifted loads, and there are differentoperation regulations for different levels of lifting operations. In the liftingoperation, safety is the first consideration. lt is very dangerous to stand underthe boom, under the suspended objects, etc. Therefore, the position of theoperator is very important. At the same time, it is also necessary to strictlyimplement the relevant safety specifications.
