"Our hydraulic press is prepared for the manufacture of heavy-duty vehicles that are in line with the world, with a forging capacity of 10,000 tons. At the same time, for some special vehicles, it can also increase the length of forging, the longest can reach more than 20 meters, you can see, we behind this 10,000-ton hydraulic press, and other 10,000-ton hydraulic press one of the biggest differences, is the length, ordinary hydraulic press, the forging surface is approximately square, this is a long shape. ”

On the TV, the news is playing, a middle-aged man in light blue overalls, is picking up the rice bowl indiscriminately, his hands are full of oil, his hair is also messy, his eyes are blood-red, and when eating, he can occasionally see the logo on the chest, on which a small strip of cloth is written, and the words Hanyang Automobile Factory are written.

Suddenly, his hand stopped, his eyes widened as he watched the news on the TV, and then, putting down the dishes and chopsticks, he strode out.

"Lao Liu, Lao Liu!" When the middle-aged woman came out to call him, he had already run away.

Alas, this Lao Liu, pounced on work all day long, went home to eat and sleep, in recent months, he was even more busy, today it is easy to go home, while watching TV and eating, it is also regarded as a rest, who would have thought that halfway through eating, he actually ran away!

She didn't know how excited her husband was at this time.

Liu Qianjian, director of the R&D office of Hanyang factory, is currently leading the technical backbone of the factory, developing key products, encountering problems that are difficult to solve, has been fighting for several months, and can not find a perfect solution to the problem, now, the content broadcast on TV, is to solve their problems, how can Liu Qianqian's heart not be excited!

He ran out in one go, rode his bicycle, returned to the factory, reported to the old factory director, and that night, with two assistants, got on the train.

Hanyang factory, not well-known in China, when it comes to heavy trucks, you can think of the Yellow River in China, and you can also think of the heavy truck joint venture company that is now vigorously engaged in the introduction of technology, and intends to digest and absorb Steyr's technology together, and Hanyang factory has not entered the ears of ordinary people.

Because it does not belong to the transportation sector, but to the military industry, just a few years ago, it has just entered the research and development of heavy vehicles, and the first product is the Type 82 tank transporter that has just been successfully developed this year.

In China, there has not been enough carrying capacity to transport tanks, usually tanks are transported by railway, and then go to the battlefield by their own power, after all, a tank is often thirty or forty tons, the old liberation, Dongfeng EQ240, are not qualified.

Only the HY473 special tractor produced by the Hanyang factory has this capability!

In the 60s, it trial-produced a torpedo transporter, and since then it has entered the ranks of military production, and then made persistent efforts to develop military vehicles such as missile carriers and boat-bridge vehicles. In the 70s, with the contradiction of lack of weight and lightness becoming more and more prominent, Hanyang factory successfully developed the HY470 25-ton 4x2 heavy-duty semi-trailer tractor in 1972, and in 1979, successfully developed the 50-ton HY473 6x4 tractor.

This tractor is equipped with a turbocharged medium-cooled air-cooled diesel engine produced by Huachai Deutz, mated to a Fuller 9-speed manual transmission. In the early eighties, this was simply a god-like existence, most of the cars only had more than 100 horsepower, 200 horsepower was against the sky, and the 500 horsepower engine was quite powerful.

In addition to the fact that it is expensive and has super fuel consumption, there are no drawbacks, and when towing, the total mass can reach ninety tons!

Relying on these tractors, the Hanyang plant deservedly became the leader of the domestic military tractors, so when the task of this parade began to be planned, the Hanyang plant also received a key task from the superiors: the tractor transport vehicle of the party-5 missile!

This missile, which belongs to the country's strategic weapon, is also the country's important weapon of the eastern powers, and this time, it will finally be displayed for the first time in front of everyone in the world!

So, how do you show it?

This missile, with a total length of more than 30 meters and a total weight of several hundred tons, is very heavy even if it is not filled with fuel.

Therefore, they need a new tractor they are developing, that is, HY480 to tow.

This tractor is 8*8, four-axle drive, although from the current point of view, that is, an extra transmission shaft is added, but in many aspects, higher requirements are put forward.

In terms of engine, they need to continue to import Deutz's air-cooled diesel engine, which needs to have more than 500 horsepower to have enough traction, and the gearbox must be matched with a torque converter to ensure the stability of traction, after all, the index of this tractor is to have a traction capacity of 200 tons!

So, what to do with the girder of the car?

A simple girder stumped them, and the only 2,000-ton hydraulic press in the factory could not be suppressed!

The pressure is not enough, the length is not enough, in short, the difficulty is too great.

Their plan is to press the two, and then rivet them, after all, the length of the first stage is about 20 meters, and the tractor has to be more than 20 meters long, and two 10-meter docks can be docked.

However, that's the party fee -5, riveted, is it reliable? If the girder breaks when passing through the parade stand, it will be a shame in front of the whole world!

In the past few days, in order to ensure reliability, they have experimented day and night, looking for various ways, and they have also thought about asking for help from other manufacturers in China, but other manufacturers do not have such large hydraulic equipment.

Who would have thought that stepping on iron shoes would have nowhere to be found, and it would take no effort to get there! Just when it was needed, as a result, there was a machine factory in Prairie City!

Although I haven't dealt with it before, but after all, everyone is inside a system, and the Type 82 transport vehicle built by our own side is still used to transport tanks, which can be regarded as intersecting, and such a major task, as long as you open your mouth, the other party will definitely not refuse.

With such thoughts, Liu Qianjin was even more eager to look forward to it, and he couldn't wait to fly to Grassland City immediately.

The farther you go north, the colder the climate becomes, and when you cross the bridge, you even start to see snow in the north, and the two assistants who are traveling with you look at the snowflakes falling outside the window, with a sense of freshness in their eyes.

"Xiao Lei, Xiao Zhao, you want to see, go to a machine factory, see enough, there, the heavy snow in winter can bury people."
