What should be done if the load begins to swing uncontrollably?

• A. Continue the lift, adjusting speed
• B. Stop crane operation, secure the load, re-evaluate and correct rigging
• C. Release the load to the ground
• D. Maintain the lift and wait for it to stop

Answer: (B)

When a load starts swinging uncontrollably, safety priority is to stop the crane, secure the load, and re-evaluate the rigging. Stopping the operation prevents the swing from getting worse and reduces the risk of contact with people, equipment, or the load itself. Securing the load and re-checking the rigging gives you a clear view of what’s wrong—whether the slings, hooks, or attachment points are mismatched, overloaded, or poorly balanced—and allows you to correct the rigging before resuming. Re-evaluate also includes ensuring the crane position, rigging configuration, and approach are appropriate for a stable lift, and that the area is clear of workers who could be injured. Releasing the load to the ground or continuing to lift with uncontrolled swing would create uncontrolled movement and hazards, so they’re not acceptable options. Once the load is properly secured and stabilized, the lift can be resumed with controlled movements.
