When forming a lift plan, a PRIMARY concern for the person doing the rigging is:

In the context of forming a lift plan, the capacity of rigging is of paramount importance because it directly relates to the safety and success of the lifting operation. The rigging equipment, including slings, shackles, and other hardware, must be rated to handle the weight of the load being lifted. If the rigging capacity is insufficient, it could lead to equipment failure, which poses a significant safety risk to personnel, equipment, and the surrounding environment.

Understanding the load's weight and ensuring that the rigging used can safely support it is fundamental to preventing accidents. This includes considering not only the static weight but also dynamic factors such as load swinging, wind effects, and potential shock loads during the lift. Evaluating the rigging capacity is the first step in the planning process and helps dictate the choice and configuration of equipment used.

Other factors, such as the type of crane, length of jib, and weight of load block, are also important considerations in a lift plan. However, they fundamentally hinge on the capacity of rigging. If the rigging is inadequate, it negates the effectiveness of even the most appropriate crane or jib length, thus making the rigging capacity the primary concern in planning any lift.
