Kick-out system disables which combination of controls?

• A. Hoist up only
• B. Boom down only
• C. Telescope out only
• D. Hoist up, Boom down, Telescope out

Answer: (D)

Kick-out serves as a safety interlock that prevents actions which could push the crane toward an unstable configuration. When this system is active, it blocks moves that change the load path or increase the crane’s outreach in a way that could raise the tipping risk. Specifically, it disables hoisting (lifting the load), extending the boom (telescoping out), and lowering the boom (boom down). By preventing these three motions, the crane stays in a more stable condition until conditions are safe again. Therefore, the action set that is disabled includes hoist up, boom down, and telescope out.
