Before energizing the crane, which position minimizes unintended movement?

• A. Hoisting
• B. Lowering
• C. Trolley
• D. Neutral

Answer: (D)

Neutral is best because it puts the crane in a non-operating state with no drive motors energized. This means no axis (hoist, trolley, or bridge) will move when power is applied, preventing the load from starting to lift, lower, or travel unexpectedly. If you set the controls to any active mode—hoisting, lowering, or trolley—before energizing, any residual power or control input could cause immediate, unintentional movement. Neutral ensures a safe, motion-free start.
