What is the purpose of gross load calculation in hoisting operations?

The purpose of gross load calculation in hoisting operations is to ensure that the maximum payload does not exceed the breaking strength of the lifting equipment and components. This calculation involves considering the total weight of the load being lifted, which includes not only the weight of the object itself but also any additional factors that could contribute to the total load on the lifting apparatus. By determining the maximum payload in relation to the breaking strength, operators can prevent equipment failure, which is critical for maintaining safety and operational integrity.

This understanding is crucial as it directly impacts the safe use of cranes, hoists, and other lifting devices. Adhering to the limits established through gross load calculations helps avoid accidents and enhances the reliability of hoisting operations.
