First Domestic Mine For Seven Days With Heavy-duty Excavator Shovel Component - Heavy Mining

"It may seem today, that heavy-duty shovel hardly anything

, but in 50 years ago, it can not just technology, it's our national pride Yeah!" Said 77-year-old Jiao Zhengyao, 50 years ago involved in assembly of the first mines in China with heavy-duty excavator W-3 type 3 m3 shovel and began to witness it thundered day operation is the pride of life are unforgettable, so until now, every time details are still so clear, vivid memories.

Shown signs: more than two hundred tons of the "big guy" Stunning debut

1957, just returned from Jilin Industrial electrical equipment school graduate Jiaozheng Yao is Anshan Metallurgical Construction Corporation (c Ye) Turkish subsidiary company. It wound up founding of New China, the state promoted the restoration of heavy industry, Anshan Iron and important moment expansion. "At that time workers are open, but also all the former Soviet Union production of power shovel, power is not big enough is not said that from the instructions to the body, are foreign code, which if broken, one can understand the drawings, no one can repair do not understand, it felt extremely go an 'suck up. "Jiaozheng Yao said after the development of our country is still not independent of heavy mining equipment, experience and ability, so the end of the year 12, when the production of heavy machinery plant in Fushun, just in December 21, the first successful trial-type 3 cubic meters W-3 Excavator parts shipped to the east of Anshan Anshan Iron and Steel sintering plant site when the Crusher, we even have a little do not believe it in front of a lot of equipment, spare parts, Zan is the first mine-made heavy-duty excavator!

Jiaozheng Yao recall, equipment shipped to, the day the company as vice president of Coke thousand construction office he found, he said: "The small coke, have a task to you to complete, it was decided by a few people with you This machine installed with the Taiwan Power Company is responsible for assembly and commissioning of electrical shovel, put into use. "" I?! "heard the news Jiaozheng Yao heart is both nervous and happy. Tension as was his first job soon, inexperienced, afraid not very well done such an arduous task. Pleased that his efforts for the construction of the motherland, to make contributions, it is a glorious thing!

So the next Jiaozheng Yao Li Shirong on and shovel driver and his apprentice Zhuo Lu, electrical Lin Cheng Jin, Jin-Ming Zhang to the technology sector took the drawings and technical data, until the scene, looked carefully again the "big head" , they once again been shaken by the beauty of this machine. "This Taipower shovel weight 200 tons, fitted with 18 motors, two transformers, the input voltage 6000 V, composed by the tens of thousands of parts, when shipped with the 7 train skin!"

Assembly: assembly tasks completed seven days of fighting

In fact, in accordance with the plan, which sets new China's first heavy-duty excavator mining platform should have shipped to Beijing in the Exhibition after off the assembly line, but considering the time the country is in urgent need for such large-scale production and construction machinery, it is not sent to Beijing, while Anshan Iron and Steel is the first time sent to the expansion of the project site.

Understand this background, Jiao Zhengyao they feel the burden of body weight, also did not slack. Jiaozheng Yao said at the time the 5-member team, he was the 24-year-old secondary school students considered "high-level intellectuals and experts only", how do? , "Can only succeed Yeah, you must eat this piece hard bone!"

"Too tired, but one we think this is a big country's own production equipment, body full of awkward! Children did so with spaces in 7 days, finally assembled into the big guy!" After think about it, Jiao Zhengyao they think that's incredible!

Test: the ecstasy of a successful

Just assembled, and also just the beginning, you know, the machine is to run up and see, if only assembled into the shell, then What? Finally to the test day, only three lead smelting and Turkish companies, almost all workers on site are coming, they want to witness the first use of domestic production of heavy excavators. Jiaozheng Yao said that as a precautionary measure, the first day of trial, he and several comrades commissioning team, but also the whole device a more thorough testing and inspection, major inspection of the circuit and so on.
