"Is this a tank modification?" The officers standing beside Tian Feng had straight eyes.

In particular, the chassis is completely no different from the 59 tank, and the upper slewing part does not have the structure of an ordinary excavator, but a cockpit and shovel arm, which looks a little awkward.

"Yes, chief, here is the 59, the turret has been changed into a cockpit, so that our excavator has a lower center of gravity, and when working, it is not easy to overturn and has a greater lifting capacity. Xie Jianguo explained.

"I'll have to take a good look. I said, Director Tian, if you told us earlier that we had this thing, we wouldn't have considered importing it! Although it can't be artillery, it's also a tank. The officer said.

Tian Feng smiled bitterly, but his eyes fell on the representatives of the excavator production unit who were still talking cool words just now.

These people were already stunned by Ray.

Can an excavator do this?

They didn't even think about it.

"This is the person in charge of the logistics of the engineering unit, Director Zhang Yongcheng. Tian Feng's attitude was much better today, and he took the initiative to introduce Zhang Yongcheng to Zheng Yucheng and Xie Jianguo.

After some pleasantries, Zhang Yongcheng asked worriedly, "The hydraulic system of this excavator is okay with the engine, right?"

The industrial heart of the country is unsatisfactory.

"The chief can rest assured that the engine is tank, absolutely no problem, and the strong power of 500 horsepower is suitable for any working situation. The hydraulic pump and hydraulic distributor are also solved, and there is no need to import. The whole excavator, not a single part is imported. Xie Jianguo said, "But in terms of quality, it may not be able to compare with foreign countries." ”

"Yes, it's not too bad!" Zhang Yongcheng said, "You don't need to use a trailer, right?"

"If the transfer of thousands of kilometers is better to be transported by train, less than 600 kilometers, forget it, a flat dirt road, the maximum travel speed can reach sixty kilometers per hour, and the fuel consumption is much lower than that of a tank, after all, it only weighs more than twenty tons. Xie Jianguo nodded and said.

"Let's look at it for a while, as long as the excavation efficiency is not much worse than Mitsubishi's, I don't care what others think, we want your excavator. Zhang Yongcheng whispered, "It's just that this is not much different from a tank, so we have to use this." ”

When Xie Jianguo heard this, he immediately frowned and looked at Tian Feng, who frowned at the Mitsubishi excavator that had only walked half the way.

"Mr. Nakamura, can you start? Now the time has come. Under Tian Feng's signal, when the Mitsubishi excavator came over, Xiao Wang asked Nakamura Hidetoshi with a blue face.

"Yes!" Nakamura nodded. "If you compare the digging efficiency and the climbing ability, we really can't compare to you who are modified with tank turf! But this does not represent the level of technology. ”

In terms of driving speed, the ratio of excavators to tanks is very different.

No one thought that the Chinese excavator was a modified tank.

It was a sure thing, but there was an accident.

"What does Mr. Nakamura mean?" Tian Feng asked.

"Wait until you get to the bottom of the mountain over there, and start at the same time. This is how the performance can be fully seen. Nakamura said.

Only in this way can China's advantage be eliminated.

"Shameless! Isn't driving speed one of the features? Do you want us to help build a road that leads to that side, or just wait until you're done before starting?" Zheng Yucheng looked disdainful when he heard the translator's words.

Komatsu Dorjee also knows that this matter must not be allowed to continue on the Chinese side, otherwise even if the Chinese side is inefficient, it will be ignored because it runs too fast.

"The work efficiency of the excavator is not comparable to the speed of travel!" Komatsu said coldly, "If it is only compared to the speed and off-road ability, there is no need for your country to introduce advanced technology to us." Just dig with a tank!"

Obviously, he is a little disdainful of this excavator modified from the chassis of this tank.

The Chinese side is playing tricks.

"The hydraulic system at the heart of the excavator does not need to be involved in the driving process. Travel speed is also not indicative of productivity. Komatsu's words embarrassed Tian Feng and the others.

Xie Jianguo and Cao Feng were even more pale.

Zheng Yucheng was on the verge of attacking, but was pulled by Xie Kai behind him.

"Since the Japanese side needs a fair game, let's wait for them to pass before we start!" Xie Kai said calmly.

He believes in the technology of Hongqi Machinery Factory, and he already understands what Zhang Yongcheng said just now.

The slopes over there are not high, but many places are steep, and the climbing degree of the excavator is very demanding.

The selection of this place requires the use of various performance indicators of the excavator, and it is not easy to climb from the bottom of the slope to the designated position on the top of the mountainside.

In a few places, the vertical height is even more than 2.5 meters, and in two places the slope is about 70 degrees.

They forgot what tanks are for.

"Then do as they ask!" Zheng Yucheng snorted coldly.

Seeing that the people in the Hongqi Factory were so confident, even Komatsu and the others became nervous.

Regardless of the excavator at the Hongqi Factory, after Nakamura Hidetoshi gave instructions to the driver, the excavator emitted black smoke from its buttocks, and the working part of it spun and ran towards the hillside not far away.

"Why don't you move? Run down the hill first, and wait for their excavator to pass and start!" Zhang Yongcheng was a little anxious.

If the excavator of the Hongqi Factory is not good at climbing, they will not be able to maintain it too much.

"Let them run for a while. Zheng Yucheng said with a look of contempt, "At this distance, when they are almost there, our excavator will climb up faster than them." ”

"Be careful to sail the ship of ten thousand years. Tian Feng reminded.

"This kind of hillside, no problem. Xie Jianguo said that he was the chief engineer, and he had conducted experiments before, and he kept testing all the way here.

The representatives of the various units who were in the audience next to them were all honest at this time.

I never heard anyone say anything cool again.

Tian Feng hasn't settled accounts with them yet.

"The work part above, can you turn it at will?" Zhang Yongcheng asked Xie Jianguo.

"No problem, 360° arbitrary rotation. The engine and hydraulic motor are in the bottom cabin, the turret of the 59 tank was originally a mechanical transmission, because there is no need to consider the recoil and the weight of the turret, the weight of the entire cockpit and shovel arm is reduced a lot, and the hydraulic motor is used to assist rotation, which is faster ......in the rotation speed," Xie Jianguo introduced.

"In this way, our thing is no worse than the Japanese one. Zhang Yongcheng said.

"Chief, in fact, this is not the case, although there are a lot of technologies on it that are military, and the quality of some parts of the hydraulic system ......" Xie Jianguo did not fool the person in charge of the military.

The processing accuracy is not enough, and there is no rich experience in the little devil, which cannot be denied.

"How long will it last?" Zhang Yongcheng frowned and looked at Xie Jianguo.

The domestic hydraulic field is not as good as foreign countries, which everyone knows, materials, heat treatment processes, processing quality, etc., all determine the service life of parts.

If the quality is too poor and replaced every day, don't expect to work.

Zheng Yucheng kept giving Xie Jianguo a look, asking him not to tell the truth, Xie Jianguo saw it and didn't pay attention to it, "There is no specific data on this yet, but so far, after we installed it, we haven't replaced it, and we checked it yesterday, and there is no problem, and there is still no problem with the working state for half a year to eight months." ”

"I thought you would tell me I could only use it for a month!" Zhang Yongcheng breathed a sigh of relief. "As long as you dare to guarantee the quality for three months, I will use your excavator!"

"Director Zhang, that's not what I said at first. Tian Feng looked at Nakamura Hidetoshi and the others not far away, frowned and said, "When the time comes, they think that we are operating in the dark, and we will be in trouble if it is difficult for other parties to cooperate." ”

"What is a black-box operation? This thing doesn't need a special trailer, and a trailer costs hundreds of thousands! Trailers are usually useless, and all we undertake are key infrastructure projects, and a project will take several years!" Zhang Yongcheng said unceremoniously. "They think we're fat sheep to slaughter. ”

"Lao Zheng, your excavator hasn't set off yet? There are quite a few trenches in front of you, dug specifically for the competition. Tian Feng reminded Zheng Yucheng again.

Zheng Yucheng glanced at it, then turned his head to look at Xie Jianguo, who said, "Chief, let them run for a while." ”

"So confident?" Tian Feng despised the most for big talk. "Don't say it's unfair when you lose. ”

"Chief, you don't worry about us, but you have to worry about our tank!" Xie Kai drilled out and said, "This kind of excavator specially built for the military engineering troops is the perfect combination of tank and excavator, due to its single function, compared with the tank, whether it is off-road speed or climbing ability, it is more outstanding!"

"Go anywhere, there's you everywhere!" Xie Jianguo glared at Xie Kai and said to Tian Feng, "He is telling the truth, many of the technologies in this can be used for civilian use." ”

"I really don't feel at ease about the production of these factories that specialize in excavators, because they are too rubbish! The quality is not good, and the efficiency is low. Zhang Yongcheng turned his head to look at the jealous delegates next to him, and said unceremoniously, "But I believe that our military technology, although it is worse than that of foreign countries, will definitely not disappoint too much." ”

The performance of the 59 tank is known to everyone.

It's not advanced enough, but it's not bad for off-road ability.

Compared with the excavator with these characteristics of the tank, it is too bullying.

The only thing to consider is how efficiently the shovel arm on the tank turf works.

"They've already run three-quarters of the way, and they'll be there when they wait!" Zhang Yongcheng couldn't help but be a little anxious when he saw that Mitsubishi's excavator was about to arrive.

Just the chassis of the 59 tank already impressed him.

He hoped that the excavator of the Hongqi Machinery Factory would show its face fiercely and suppress the arrogant Mitsubishi.

Zheng Yucheng looked at it, saw Xie Kai shaking his head, and said calmly, "It's okay, let them run for a while." "Mobile phone users, please browse and read, a better reading experience.
