On the morning of March 18th, at the scene of No. 4 dock of Jiangnan Shipbuilding Changxing Shipbuilding Base, the ceremony of the 1600-ton gantry crane with the highest weight and the highest lifting height was held. Zhenhua Heavy Industry and Jiangnan Shipbuilding Co., Ltd. signed a delivery certificate, marking the 9-month period of Zhenhua Heavy Industry, the carefully constructed gantry cranes, and the successful delivery. 
The gantry crane has a maximum lifting capacity of 1,600 tons, a turning weight of 900 tons, a gauge of 158 meters, and a net height of 95 meters at the bottom of the beam. It is the highest and largest gantry crane in China.
It is reported that the 1600-ton gantry crane of Jiangnan Shipbuilding Changxing Shipbuilding Base signed a purchase contract on March 18, 2015, and started construction on June 8, 2015. On November 24, 2015, the overall hoisting was successfully completed, creating a total of 4 days to complete the overall lifting. history record.
During the implementation of the project, the main nodes progressed in an orderly manner. Especially at the end of November 2015, the project department used ZPMC's self-produced 5,000-ton floating crane to complete the gantry crane safely and smoothly in only 5 days without affecting the shipyard production. Hoisting work. In the following four months, overcoming the difficulties of completing most of the work at a height of 95 meters or more, successfully completed the electrical wiring, commissioning, commissioning, type testing, forensics, etc., to achieve the project milestone plan as scheduled, and The third-party supervision company carries out the whole process of supervision, and its main performance and parameters have fully met the contract, technical specifications and usage requirements, and have been highly evaluated by users.
Why do large gantry cranes cause speculation about the start of domestic aircraft carriers?
On March 21, 2014, China's newly built 052D destroyer first ship held a grand ceremony in Jiangnan Changxing Shipbuilding and officially joined the Chinese Navy battle sequence. The ship's number 172 was named the Kunming ship.
As early as last November, after the hoisting of the 1,600-ton gantry crane of the Jiangnan Shipbuilding Changxing Shipbuilding Base, some media said that as the largest and highest gantry crane in China, the smooth assembly of the gantry crane indicates that China will have a 100,000-ton aircraft carrier. Ability, and triggered speculation that the domestic aircraft carrier has started.
Why does the media always associate the gantry crane with the aircraft carrier? Because gantry cranes play an important role in the construction of aircraft carriers and large ships. Modern large-scale aircraft carriers generally adopt the giant total section construction method, that is, before the final assembly of the hull, the super-large hull sections are first manufactured in the onshore factory, and finally the aircraft carrier structure is assembled by assembling these giant total section structures. The assembly of such a large hull structure inevitably requires the use of large gantry cranes.
According to media reports, the bridge crane used in the construction of the Elizabethan aircraft carrier in the UK was manufactured by Zhenhua Heavy Industry. It is understood that the United Kingdom used the giant total section construction method in the construction of the "Elizabeth" class aircraft carrier.
On June 29, 2011, Shanghai Zhenhua Heavy Industry delivered a 1,000-ton gantry crane to the British Roses Shipyard. The purchase of the Chinese 1,000-ton gantry crane by the Roses Shipyard is mainly for the construction of the "Elisabeth" aircraft carrier with a displacement of more than 60,000 tons. The gantry crane is responsible for the carrier hull section, the raft section, the "island" superstructure and the aircraft. Lifting and installation work of the lift. It is reported that in 2014, at the launching ceremony of the "Elisabeth Queen" aircraft carrier in the United Kingdom, the heavy-duty gantry crane used in the assembly of the "Elisabeth Queen" aircraft carrier was printed with the words "Shanghai Zhenhua".
It is understood that the only one of the US Newport News shipyards capable of designing and constructing a nuclear-powered aircraft carrier has installed a Chinese-made giant gantry crane with a maximum lifting capacity of 1,050 tons. It is known as the largest gantry crane with the highest lifting capacity in the Western Hemisphere. The length of the dock is about 743.7 meters in length and the main beam span is 164.6 meters. There are 3 lifting blocks on the main beam, each with a lifting capacity of 300 tons. In addition to crossing the dock and crossing the adjacent assembly area, this gantry crane can easily hang the assembly area into the dry dock. When constructing the "Bush" aircraft carrier, the heaviest hoisting crane was a section of the flight deck weighing 865 tons.
At present, the gantry crane of Dalian Shipbuilding Heavy Industry can lift a large section of 1,200 tons.
Steel Tubing is a hollow steel shape intended for structural purposes and made from carbon, stainless, or galvanized steel further divided as:
Mechanical Tubing is used in low stress applications such as fences, kitchens, restaurants, hospitals, solar panels and made with wall thicknesses up to 10 gauge.
Structural Tubing is for high stress structural application like bridges, buildings, roll cages, and underwater platforms with wall thickness from 3/16" and up. It is often referred to as Hollow Structural Sections or just the acronym HSS.
Pipe is a hollow structure that is intended to carry material such as liquids, gasses, or even solids. Its wall thickness is described by its Schedule and it is often broken down by type using the method of manufacturing it, either ERW or Seamless.
