Knuckle Crane For Boat Ship Vessel
There are three major considerations in the design of cranes. First, the crane must be able to lift the weight of the load; second, the crane must not topple; third, the crane must not rupture.
loating cranes are used mainly in bridge building and port construction, but they are also used for occasional loading and unloading of especially heavy or awkward loads on and off ships. Some floating cranes are mounted on pontoons, others are specialized crane barges with a lifting capacity exceeding 10,000 short tons (8,929 long tons; 9,072 t) and have been used to transport entire bridge sections. Floating cranes have also been used to salvage sunken ships.
Crane vessels are often used in offshore construction. The largest revolving cranes can be found on SSCV Thialf, which has two cranes with a capacity of 7,100 tonnes (7,826 short tons; 6,988 long tons) each. For 50 years, the largest such crane was "Herman the German" at the Long Beach Naval Shipyard, one of three constructed by Hitler's Germany and captured in the war. The crane was sold to the Panama Canal in 1996 where it is now known as the "Titan."
Our crane is common crane, according to your requirement about lifting weight , boom length ,etc to manufacture the crane. Since boat space is different, so we will send drawing to you, if you feel ok, we will make the cranes according to your requirement and drawing.
