Shipbuilding Gantry Crane

Description

Shipbuilding gantry crane is the core lifting equipment of modern shipyards, mainly for large hull segment lifting, precise positioning, turnover operations and ship platform assembly. Its main structure uses box beam or triangular truss structural gantry welded with high strength steel plates, which has extremely high bending and torsional resistance. The standard span is between 50-185 meters and can reach a maximum of more than 200 meters. Legs on both sides of the gantry are designed with box structure. It has th hydraulic automatic leveling system or mechanical height adjustment device, which can compensate for the rail surface height difference caused by tidal changes in real time, and meet the construction needs of ships with different tonnages. The entire surface is heavily anti-corrosion coating, and there is anti-salt spray seal to ensure long-term operation in a coastal high-humidity and high-salt spray environment.

The lifting mechanism adopts an advanced multi-lifting point intelligent collaborative control system. And rated lifting capacity is usually in the range of 300-1000 tons, with a maximum of 3000 tons. 4-8 sets of independent wire rope hoisting systems are equipped with dual braking safety devices, and real-time load monitoring and automatic balanced distribution are achieved through PLC and sensors. Hook group can achieve an automatic deviation correction function of ±5°. Operating mechanism adopts multi-motor variable frequency drive, sets a balance beam structure of 16-32 wheels, and is equipped with a laser positioning system to ensure millimeter-level positioning accuracy.

The intelligent safety system integrates multiple protection devices, including three-dimensional anti-collision system, real-time wind speed monitoring and alarm, dynamic load monitoring, emergency backup power supply, etc. It is a key equipment to improve the production efficiency of the shipyard and ensure operation safety.

Caractéristiques

Strong lifting capacity: Shipbuilding gantry cranes usually have very high rated lifting capacity and can easily handle hundreds or even thousands of tons of weight. This strong lifting capacity makes it very suitable for handling and assembling large hull sections, heavy machinery components, etc.

High flexibility and adaptability: The design of this type of crane takes into account the complex operating environment and changing work requirements of the shipyard. With multi-functional hook groups or special grabs, it can adapt to different operating needs by adjusting the main beam height, span and trolley position.

Accurate operation control system: In order to ensure the safe operation, shipbuilding gantry cranes are equipped with advanced electrical control systems. These systems support precise speed control, positioning accuracy, and smooth starting and stopping.

Good stability and structural strength: Due to the need to work outdoors and on relatively uneven ground, shipbuilding gantry cranes have extremely high structural strength and stability. Its outrigger design pays special attention to resisting lateral forces and capsizing risks, ensuring safe operation even in severe weather conditions.

Weather resistance and anti-corrosion design: Considering the influence of harsh environmental factors such as high humidity and salt spray in coastal areas, shipbuilding gantry crane usually takes special materials and surface treatment technology to enhance weather resistance and corrosion resistance and extend service life.

Application

• Hull block assembly: During the shipbuilding process, the hull will be divided into multiple parts or blocks for manufacturing. Shipbuilding gantry cranes can efficiently move these large and heavy sections and accurately place them in the correct position for assembly.
• Outfitting operations: Outfitting refers to the installation of various equipment and facilities inside and outside the ship, such as engines, navigation equipment, living facilities, etc. Shipbuilding gantry cranes can lift these heavy equipment and install them accurately and accurately in the designated location on the ship.
• Repair and dismantling: In addition to new shipbuilding, shipbuilding gantry cranes are also widely used in the repair and dismantling of old ships. During repairs, it can remove damaged parts and install new components.
