Lifting operations 3: Which lifting operations require the preparation of a lifting plan?

1. Level-1 lifting operations. 2. Secondary lifting operations. 3. Lifting operations of objects with complex shapes, low stiffness, a large length-to-diameter ratio, and high precision or value.

The above three scenarios are situations where the risks are relatively high and accidents are likely to occur during operations; thus, they require great attention during the course of operations. For Level 1 and Level 2 lifting operations, given the heavy weight of the loads being lifted, any accidents could have relatively serious consequences; therefore, a corresponding lifting plan must be developed. Although the mass of the object to be lifted is less than 40 tons, it has a complex shape, low stiffness, a high length-to-diameter ratio, and is delicate and valuable. Moreover, it involves level-3 lifting operations under special working conditions. Due to its delicacy and value, an accident could result in significant economic losses ； For lifting operations involving objects with complex shapes, low stiffness, a large length-to-diameter ratio, or under special operating conditions, the potential risks are relatively high. Preparing a lifting plan is essential to ensure the safe execution of such operations. The lifting plan should specify the procedures for lifting operations, conduct a comprehensive analysis of potential risks that may arise during such operations, and formulate corresponding safety control measures. At the same time, the plan should also specify the measures to address potential accidents that may occur during lifting operations, including injuries to personnel and damage to lifting equipment. Therefore, a lifting plan must be developed and strictly reviewed and approved in order to keep risks within acceptable levels.
