Which crane type is specifically mentioned as requiring hooks to be secured to the carrier frame during transport?

• A. Truck crane
• B. Floating crane
• C. Tower crane
• D. Bridge crane

Answer: (A)

Securing the hook during transport is about preventing any movement or swinging of the lifting gear while the crane is being carried on a truck. A truck crane sits on a road-going carrier, so the hook and load line can swing or shift due to acceleration, braking, and bumps. Tying the hook to the carrier frame locks it in place, protecting people and other vehicles and avoiding damage to the rigging. This precaution is specific to truck cranes because they are designed to move in a ready-to-use configuration on public roads. Other crane types are typically not transported in the same way: tower and bridge cranes are fixed or disassembled for transport, and floating cranes move by water, which involves different transport practices.
