China has developed a new large-tonnage heavy duty dump truck to break import dependence

The reporter learned from China Aerospace Science and Industry Corporation on the 16th that the 220 tons of new energy-saving multi-axle heavy mining dump truck independently researched and developed by the Fourth Institute of China Aerospace Science and Industry Corporation has been successfully delivered to users, breaking China's large-tonnage heavy-duty The long-term dependence of unloading vehicles on foreign imports indicates that China's large-scale open-pit mining equipment manufacturing technology has reached the world's advanced level.

At the end of 2012, the first 220-ton mine dump truck in the China Aerospace Science and Industry Fourth Institute carried out a four-month trial trial in the grassland mining area of â€‹â€‹Inner Mongolia to complete the cold zone suitability test, the no-load function test of the vehicle, and the full-load function test of the vehicle. The mine uses reliability performance tests and other performance tests, and carries out an all-round assessment of the structure, performance, and manufacturing quality of the vehicle. The hospital has thus become one of the few companies in the world that can produce 220 tons of heavy mining dump trucks.

According to reports, the China Aerospace Science and Industry Fourth Institute has established a heavy engineering equipment design institute, Aerospace Heavy Engineering Equipment Co., Ltd., specializing in R&D, production and operation of heavy equipment, and developing and developing mine watering trucks, wheel loaders, and hydraulic excavators. The mining machinery and high-end equipment such as electric shovels, trackless rubber wheels, and auxiliary vehicles have now basically formed an industrial chain development pattern.

In order to promote the development of heavy engineering equipment, the China Aerospace Science and Industry Fourth Institute has also cooperated with well-known foreign companies in the development of two-shaft electric wheel dump trucks with a load of 363 tons and 110 tons. The cooperation project is now being fully promoted. The 363 tons of products that went offline at the end of this year are currently the largest dump trucks for dump trucks in the world. At the same time, the aerospace and heavy industrial equipment industry park with a total investment of 5 billion yuan was also laid in Xiaogan, Hubei in May last year.

The person in charge of China Aerospace Science and Industry Fourth Hospital stated that the new large-tonnage mining vehicle project is only the first step in the heavy equipment industry of the hospital. Its future development goal is to create a first-class heavy engineering equipment technology center and a first-class heavy engineering equipment industry base. .
