A crane operator is preparing to lift a load on a construction site. The ground conditions appear stable, but there is a buried utility line (water main) running directly under the intended outrigger placement. What is the primary concern regarding setting up the crane in this location?

Question: A crane operator is preparing to lift a load on a construction site. The ground conditions appear stable, but there is a buried utility line (water main) running directly under the intended outrigger placement. What is the primary concern regarding setting up the crane in this location?

Answer options:

• The crane's counterweight might snag the line during rotation. ✅ The outrigger pressure could damage the buried utility line, causing a rupture.
• The lift radius would be unnecessarily restricted due to the presence of the utility.
• The ground might become unstable if the water main was pressurized.

Correct answer: The outrigger pressure could damage the buried utility line, causing a rupture.

Explanation: Outrigger pads concentrate significant weight onto a small area. Setting up directly over a buried utility like a water main can exceed the pipe's crush strength, leading to damage or rupture. The primary concern is protecting the utility and preventing ground instability. The other options are less likely or not the main concern.
