How should heavy loads be positioned on a crane's hook?

Heavy loads should be positioned centered on a crane's hook to ensure proper balance during lifting. This practice minimizes the risk of the load swaying or rotating, which can occur when the load is off-center. Centering the load is crucial for maintaining stability and control, particularly when the crane is in motion. A balanced load helps to prevent tipping or sudden shifts in weight that might compromise safety and efficiency.

Additionally, placing the load in a centered position allows for a more predictable operation, as it aligns the center of gravity with the crane's vertical lifting axis. This alignment reduces strain on the crane's components, including the hook, cable, and other lifting mechanisms, thereby extending their service life and enhancing overall safety during operations.
