What is the first step in calculating the load before a lift?

Calculating the load before a lift begins with obtaining an accurate load weight because this measurement is critical to safe lifting operations. The load weight ensures that the crane and its rigging are not overloaded and can safely handle the intended lift. An accurate load weight allows operators to assess the capacity of the crane, select the appropriate equipment, and determine the proper rigging method needed for the lift.

Knowing the precise weight of the load helps in creating a safe lift plan, including identifying the center of gravity and any potential dynamic forces that may be involved when the load is in motion. Without this foundational information, it would be challenging to make informed decisions about rigging and safety precautions, which could lead to dangerous situations.

Other steps, such as determining the height of the lift and calculating rigging weights, are important but follow after establishing the accurate load weight. Estimating using previous loads does not provide the reliability needed for safety, as previous loads might not accurately reflect the current load's conditions or specifications.
