Floating Crane



Floating crane is one mobile crane, they are sea vessels have cranes mounted on them or ships equipped with cranes but not like deck cranes. They are mainly used in building bridges and port construction. 


They are capable of carrying whole sections of bridge through the water and installing it in position due to their loads capacity which exceeds 10,000 ton their capacity of loading is great. These types of missions are often made increasingly difficult by rough sea conditions. It requires an experienced operator and crew to complete successfully a lift in these conditions. 

These cranes are also used in salvaging sunken ships and other offshore operations. These cranes speed the work at the oil rigs construction. The floating cranes type was known in 1920, since this date, they are widely used in all offshore construction. The massive weight of these cranes gives them the stability in water. 

The floating cranes work with the electric system for powering wire ropes that lift the loads. The earliest floating crane designs were no more than old ships converted to include a large crane mounted on the deck.
