During a multi-crane lift operation with 3 cranes, what percentage of the load share must be added to each crane's capacity?

In a multi-crane lift operation, effective load sharing among multiple cranes is crucial for ensuring safety and balance. When three cranes are utilized in a lift, each crane is responsible for handling a portion of the total load.

Typically, the total load is divided evenly among the cranes. For three cranes, this means each crane should ideally lift one-third of the total load, which is approximately 33%. This considerations take into account not only the weight of the load but also dynamic factors such as sway, wind, and moving loads, which can affect stability during the lift.

Thus, to ensure adequate margin and account for any unforeseen circumstances, the recommended load share is to add a percentage to each crane's rated capacity. Adding 33% is a standard practice to ensure that the cranes can manage not only the weight of the load but also allow for operational safety margins, thus maintaining a robust and effective lifting operation.

This principle emphasizes the importance of planning and calculating load distribution accurately to prevent overloading any single crane and to support safe and efficient lifting operations.
