What steps should be taken if a load starts to swing uncontrollably?

• A. Stop hoisting, lower the load if possible, communicate to the crew, use tag lines to regain control, and reassess the lift.
• B. Continue hoisting and try to pull the load into position.
• C. Ignore the swing and wait for it to settle on its own.
• D. Detach rigging and let the load drop.

Answer: (A)

When a load starts to swing uncontrollably, the priority is to regain control quickly and protect people and equipment. Stop hoisting to stop adding energy to the motion. If possible, lower the load slowly to reduce momentum and bring the swing under control. Communicate with the crew so everyone knows what to do and can coordinate actions. Use tag lines to apply controlled, lateral forces from the ground to guide and stabilize the load; tag lines provide a direct way to influence the load without relying solely on the crane controls. Once the load is stabilized, reassess the lift by checking crane stability, loading, rigging, wind, and the path of travel to determine the safest next steps. Continuing to hoist to pull the load into position would exacerbate the swing, ignoring it won’t stop the motion, and detaching rigging and letting the load drop creates a high risk of injury and damage.
