Change puzzle difficulty

Cranes are an essential part of unloading containers from cargo ships in large ports. These towering machines use their long arms to pick up and move the containers from the ship's deck to the dock. The process of unloading containers from a cargo ship can take several days, as each container is carefully positioned onto waiting trucks and transported to their final destination. It's a fascinating sight to see these massive cranes at work, efficiently moving containers of all shapes and sizes from the ship to the shore.
