Overhead Crane Practice Test

What should be done with an unbalanced load during a lift?

1. Lift slowly to avoid tipping

2. Lower it for adjustment

3. Position it vertically over the load's center of gravity

4. Secure it with additional rigging

The correct answer is: Position it vertically over the load's center of gravity

Positioning the load vertically over its center of gravity is crucial for ensuring stability during a lift. When a load is lifted evenly and directly above its center of gravity, it maintains balance, reducing the risk of tipping or swinging. This alignment allows for greater control and safety, allowing the operator to perform the lift without unexpected movements that could pose hazards to workers or damage to the load itself. In situations where the load is unbalanced, maintaining this vertical alignment is even more important. It minimizes the shifting of weight and helps the crane handle the load more effectively. This practice is fundamental in crane operations, as it adheres to safe lifting protocols and best practices. The other choices highlight important considerations but do not address the priority of balancing the load. Lifting slowly can mitigate some risks associated with an unbalanced load, but it is not sufficient to prevent issues entirely. Lowering the load for adjustment and securing it with additional rigging are also valid actions, but correcting the load's center of gravity should take precedence to prevent complications during the lift.
