Too self-developed 35 cubic meters of mining excavator

When I saw the 13-meter-high, hundreds-ton-tall "iron guy" in front of me, the reporter couldn't help but admire: "It's amazing to be able to produce such a large excavator too much!" Taihe Group, standing aside, excavated coking points. Company manager Lian Guangshe took the message: "There is even bigger than this! This is only 10 cubic meters. The 35 cubic meters we produce are mostly larger than this. Only the bottom plane of the coal bucket can stand 120 people!"


This larger "guy" is the KW-35 mining excavator, which is independently developed and produced by Taiyuan Heavy Machinery Manufacturing Group and has completely independent intellectual property rights. When it comes to "KW-35", the manager of the company will never stop: "The weight of 1050 tons, the height of 26 meters, the working radius of 24 meters, a bucket can catch more than 60 tons, equivalent to a train skin, is currently in Kazakhstan The general assembly and commissioning in the Erwusu open-pit coal mine is about to be put into production..."

Speaking of the R&D process of KW-35, Wang Xiaoming, the head of its R&D team and senior engineer of Taizhong Technology Center, said that in the 1980s, Taihe introduced the production technology of large-scale mining machinery and equipment from a foreign company. But the real core technology has not been available. In a single contract in July 2004, foreign companies wanted us to produce, but the price was far less than the production cost, and refused to increase the price. This incident deeply hurt us, so someone proposed to produce this equipment autonomously. The objection is particularly big: "If you can't do it, even the current share will be lost. It's too heavy to be bankrupt!" "If successful, you can squeeze foreign companies out of the Chinese market!" After 10 months, too heavy self-production The KW-20 mining excavator is officially shipped. After more than one year of operation, the performance has reached the international advanced level, the highest monthly output exceeded 510,000 cubic meters, and the operating cost is less than 50% of foreign machinery. Subsequently, the KW-27 and KW-35 models were developed in a serious manner, which truly ended the long-term monopoly of over 20 million tons of open-pit mining excavators in China.

Gao Zhijun, Chairman of Taizhong Group, told reporters that it has been fully introduced, digested and absorbed foreign advanced technology and co-manufactured by more than 20 years. It has completely mastered the complete design, materials, welding, hot and cold process and installation and debugging technology of mining excavators. Etc., so that the products have reached the advanced level of international similar products. At present, mining excavators that are too heavy to produce themselves have been exported to countries such as India and Peru.
