Which action helps ensure safe signaling before moving a load over a new path?

• A. Sound the horn
• B. Engage the emergency brake
• C. Increase load line tension
• D. Brief the crew in the cab

Answer: (A)

Audible signaling before moving a load is essential for safety. Sounding the horn serves as a clear, immediate warning to everyone in the vicinity that the crane will start moving along a new path, giving ground personnel time to clear the area and avoid the load’s swing or travel path. The other options don’t provide that broad warning: engaging the emergency brake would stop the crane but won’t alert workers; increasing load line tension is a mechanical adjustment and doesn’t communicate movement; briefing the crew in the cab helps the operators but doesn’t reach people outside the cab who need to know the plan.
