Which Category 2 operator aid monitors the position of outriggers?

• A. Boom angle indicator
• B. Outrigger position monitor
• C. Jib length indicator
• D. Rail clamps

Answer: (B)

Outrigers are what keep a crane stable during a lift, so having a device that gives real-time feedback on their deployment and position is essential for safe setup. The outrigger position monitor is specifically designed to show whether each outrigger is fully extended, correctly located, and within the stability limits defined for the lift. This helps the operator verify the crane is configured correctly before lifting, reducing the risk of tipping.

Boom angle indicator measures the boom’s tilt, which is important for reach and load calculations but not for confirming outrigger deployment. Jib length indicator shows how long the jib is extended, not the outrigger status. Rail clamps are hardware used for securing rails, not for monitoring outrigger position.
