Over the past year, Chinese heavy machinery enterprises overcame multiple difficulties and persisted in technological innovation and research and development, and a number of major technological achievements filled the national gap. According to the information released by the China Heavy Machinery Industry Association, China Industry News reporters took a look at the heavy equipment industry and saw the technological achievements made by the industry in the past year.
Crane field products to break foreign technology monopoly
The world’s largest 550-ton casting crane made by Heavy Cargo Group was successfully delivered. The crane adopts the innovative bridge structure form, simplifies the wheel arrangement mode, reduces the weight of the vehicle running mechanism, and realizes the lightweight of the product.
Citic Heavy Industries research and development of the largest grasping weight, the longest cantilever stroke of the seven-axle heavy load hydraulic mechanical arm, broke the foreign technology monopoly, the maximum grasping capacity of up to 2.5 tons, the use of full hydraulic drive, mainly by walking car body assembly, telescopic arm assembly, arm assembly, wrist assembly, hydraulic system, electrical control system and other parts.
The flexible multi-fulcrum long-span aircraft maintenance crane made by Aolitong Crane has been put into use in Haikou Airport Hainan Airlines Base. The 6-fulcrum, 72-meter span aircraft maintenance crane adopts the patent technology of “flexible main beam” and “flexible lifting point” of Olitong, which fully guarantees the smooth operation of the crane in the large grid hangar, completely eliminates the hidden trouble of rail nipping, and also has good adaptability and compensation ability for the deformation of the hangar grid roof.
Import substitution of ultra-supercritical key components is realized
The shipment of the first 1000MW ultra-supercritical turbine FB2 rotor developed by the second Equipment symbolizes that the key core component of the ultra-supercritical turbine FB2 high pressure rotor forgings have been replaced by imports, and the complete localization of Chinese ultra-supercritical turbine units with tens of millions of units has been realized.
New technologies in the field of transport equipment were unveiled
China Huadian independent research and development of the first set of new efficient crossing shore bridge launched in the world. The equipment is developed, designed and manufactured by Huadian Heavy Industry. A number of technologies have been used at home and abroad for the first time. It has innovated and developed a series of new technologies, such as the new structure of the independent up and down traversing double trolley, intelligent dynamic vibration reduction system, new energy saving system, intelligent control system, intelligent double trolley ECS system and so on
