Might Machines Cranes

Children always get excited watching cranes reach for the heights. Knowing that one person is perched high atop the crane only adds to the thrill and sense of adventure. Cranes are used for lifting almost any heavy load and moving it to a height. They are used to make buildings, bridges and ships. Some are used to stack containers onto ships, trains and trucks. A floating crane might be used for salvaging a sunken ship, and an aerial crane is a specially fitted helicopter that can rescue someone or drop emergency supplies into a disaster area.
