In multiple crane lifts, what is the maximum loading capacity for each crane?

In multiple crane lifts, it is important to understand load management to ensure safety and prevent accidents. The maximum loading capacity for each crane during a multiple lift operation is typically limited to 75% of its total rated capacity. This reduction is necessary for several reasons, including accounting for dynamic factors like load sway, variations in lifting performance, and potential imbalances caused by the coordination of multiple cranes.

By limiting each crane to 75% of its capacity, you maintain a higher safety margin and reduce the risk of overloading, which could jeopardize the integrity of the cranes and the safety of personnel involved in the operation. It also helps accommodate any unexpected conditions such as wind or sudden movements during the lift that could introduce additional forces on the cranes.

This guideline aligns with industry best practices and safety standards aimed at ensuring reliable and safe operation during complex lifting scenarios, thus making 75% the correct maximum loading percentage for each crane in such situations.
