What determines the position of the heaviest crane during a multiple crane lift?

In a multiple crane lift, the position of the heaviest crane is primarily determined by the load center of gravity. The center of gravity is the point where the weight of the load is evenly distributed in all directions. During a lifting operation, it is critical to determine this point to ensure stability and safety. Placing the heaviest crane in a position that aligns with the load center of gravity helps to balance the forces acting on all the cranes involved in the lift.

When the heaviest crane is correctly positioned relative to the center of gravity, it can more effectively manage the load without causing instability. This careful positioning helps prevent accidents and ensures that the lifting operation will proceed smoothly.

While the other factors, such as operator preference, environmental conditions, and the type of load, may influence aspects of the lift, they do not take precedence over the fundamental requirement to align the cranes with the load's center of gravity to maintain balance and safety during the operation.
