What steps should be taken when parking and storing a mobile crane after use?

• A. Park on slope; retract outriggers; leave the load raised
• B. Park on level ground; retract outriggers; lower loads; chock wheels; secure with immobilizers; disconnect power; store away from traffic or hazards; perform post-operation inspection
• C. Park on level ground; leave outriggers extended; leave the load raised
• D. Park near other equipment; avoid inspection

Answer: (B)

Parking and storing a mobile crane after use focuses on keeping the machine from moving, tipping, or being started accidentally, and then checking it for any issues before the next job. Park on level ground to maintain stability and to make it safe to retract the outriggers and position the crane for storage. Retract the outriggers so the crane sits compactly and doesn’t drag or catch on ground surfaces or obstacles. Lower any remaining load to a safe position to remove loads from the hook and prevent swinging or unexpected weight affecting the crane’s balance. Chock the wheels to prevent movement, especially if there could be slope or hydraulic leaks, and secure the crane with immobilizers to deter unauthorized use. Disconnect the power to ensure controls can’t be operated and the crane can’t be started unintentionally. Store it away from traffic, pedestrians, and other hazards to reduce the risk of collisions or interference. Finally, perform a post-operation inspection to check for leaks, damage, or wear on hydraulics, brakes, tires, and outriggers, and to confirm everything is in good condition for the next deployment. Options that leave the crane on a slope, keep outriggers extended, leave the load raised, or skip inspection introduce clear safety risks and are not appropriate.
