Question: When operating a mobile crane, what is the primary consideration before initiating a 'swing' motion with a load?

Answer options:

• Ensuring the boom angle is at its maximum.
• Verifying the outriggers are fully extended and properly set. ✅ Checking for overhead obstructions in the swing path.
• Confirming the counterweights are at their minimum setting.

Correct answer: Checking for overhead obstructions in the swing path.

Explanation: Before initiating a 'swing' motion, especially with a load, the primary consideration must be checking for any overhead obstructions, power lines, or other structures in the path of the boom and load. Failure to do so can lead to serious accidents. While outrigger setup is crucial for stability, it primarily relates to the whole lift operation, not specifically commencing a swing after the lift is set up, and boom angle and counterweight settings are operational considerations during the lift.
