What general principle governs the safe lifting of loads in crane operations?

The principle that governs the safe lifting of loads in crane operations is centered around the maintenance of the load's center of gravity. When lifting, it's crucial to ensure that the crane's lifting configuration and the rigging system are designed to keep the load balanced and stable. This minimizes the risk of the load swaying or tipping, which could lead to accidents or equipment failure.

Maintaining the center of gravity helps to distribute the load evenly across the crane and prevents any imbalances that might occur during the lift. A load that is balanced and has its center of gravity maintained is less likely to shift unexpectedly, which contributes to both operator safety and the safety of surrounding personnel and equipment.

In contrast, prioritizing speed or minimizing lifting height could compromise safety and is not a fundamental principle of safe lifting. Additionally, the notion that heavy loads must be lifted first does not take into consideration the importance of balancing the center of gravity during the lifting process, which is paramount in reducing risks associated with crane operations.
