Which of the following is a critical responsibility of the person responsible for the lift?

Calculating load weight is a critical responsibility of the person responsible for the lift because it ensures that the crane is not overloaded, which can lead to catastrophic failures and accidents. Knowing the exact weight of the load allows the operator to select the appropriate crane, rigging, and equipment to safely carry out the lift. This calculation also informs the operator of the crane’s lifting capacity and helps in planning the lift effectively, adhering to safety protocols, and maintaining compliance with regulations.

In the context of lifting operations, accurately determining load weight helps in preventing oversights that could compromise safety. This includes considering dynamic factors such as swinging and aerial movements that could affect the stability of the load during movement. Accurate weight calculation is essential for evaluating the load's impact on the crane’s center of gravity and ensures that a safe lifting plan is executed.
