Deck Crane

Deck crane a fixed crane, this type of cranes is fixed to the ships or boats deck. This gives the ship advantage as it can load it self without the help of gantry crane or container crane. The ship with deck crane can be used for cargo operation and loading/unloading from shores without loading facilities.

Also it can be used for shipping other ships in water. This type is powered by many systems such as hydraulic system and electric system. Deck crane consists of two main parts, the first is the one fixed to the ship deck and the other is the crane's arm that moves in horizontally and vertically to control the load as desired. 

These cranes were first used on offshore oil platforms In loading equipment from ships to the platform and oil barrels to the ships. The only disadvantage is that it is fixed, that force loads to come to its operating area to lift them besides the weight of the crane which is not an issue for huge ships. The length for loading arm is very important, it gives bigger operating radius. The arm's range is from five m to 18 m in hydraulic cranes
