Chapter 421 Electron tube manufacturing technology!
The birth of the Thomson excavator is of historic significance. It created the Panama Canal, a miracle of human engineering, for the United States, connecting the Pacific Ocean and the Atlantic Ocean, and enabling the United States to embark on the road to becoming an industrial power. Its industrial construction and development speed is the fastest in the world.

The railway network that spread across the country during the Tsarist Russia era, the railway networks of Britain, Germany and France, the factories and cement roads that sprang up everywhere during the Soviet era, these large-scale construction machinery are behind any industrialized country.

This is one of the greatest inventions in human history.

The genuine Thomson, the Tsarist Russian version of Putilov, the Soviet version of Kovrovzs, with this mechanical monster that embodies human wisdom, the base industry will make up for its own shortcomings, thereby greatly improving mining efficiency, and laying the foundation for the rapid development of heavy industry and military industry.

In the future base railway network, thermal power plants, engineering construction, road projects, military bunkers, any place can use excavators to improve work efficiency and save labor. Its importance and significance are self-evident.

Currently, there are a total of 13,000 miners in the major mines in the base area. If the use of excavators can save 10,000 miners, it will be possible to increase 10,000 full-time workers, or 10,000 fighters, in other areas.

"I have seen the original Thomson in the United States. The Soviet imitation is the Kovrovz excavator. Of course, the comprehensive performance of this excavator can no longer keep up with the needs of the times. After we get the complete drawings, we can improve it while producing it. The improvement direction refers to the current mainstream fields. The steam power is replaced by an internal combustion engine, with a diesel engine as the power core, the chain drive is replaced by a hydraulic drive, and the current mainstream high-pressure plunger hydraulic pump is used. The walking chassis is replaced from a train platform to a track drive similar to a tank. After such changes, the use scenarios can be greatly improved and the defects of relying on rails for mobility can be eliminated."

Zhuang Qianding continued, "The entire excavator is divided into the original version and the new version. The original version is more often used in mines, while the new version is suitable for most work scenarios, contributing to the construction of base road projects and industrial development, as well as the construction of fortifications by the troops. The northern region is cold in winter and the soil will freeze. The efficiency of civil engineering operations relying solely on a single soldier and a shovel is low. If there is a small excavator to assist, the efficiency of building defensive positions and fortifications can be greatly improved."

A perfect solution. Who in this world can refuse an excavator? ——Yu Hua was moved when he heard the detailed solution given by Zhuang Qianding. In the depths of his mind, he could not help but imagine a large number of excavators in the future. He was filled with yearning.

Sany XCMG, Carter Komatsu, Hitachi Kubota, and the super industrial monster Liebherr R9800, equipped with a double V-type diesel engine with a maximum horsepower of 4000 and a bucket capacity of up to 42 cubic meters.

This is the mecha in all boys’ hearts!

Improve the efficiency of building defensive fortifications?

The old leader and Zhao Erlu had no reaction to the previous series of introductions, but when they heard about the military applications later, their heartbeats suddenly quickened. They subconsciously looked at each other and discovered the meaning in each other's eyes.

Oops, this is... a heart-pounding feeling.

The old leader cannot intuitively feel the importance of excavators to industrial development and engineering construction, but if we talk about application scenarios in the military field, I'm sorry, I won't be sleepy anymore.

"Professor Zhuang, how efficient is this small excavator you mentioned in digging holes?" Out of professional sensitivity, the old leader immediately asked the key question.

"This small excavator weighs about eight tons and can move about 40 cubic meters of earth per hour. Based on this efficiency data, the earthwork volume can be calculated. A tunnel with a depth of one meter, a width of one meter and a length of 200 meters can be completed in about five hours. Five excavators can complete the operation of the entire tunnel in one hour." Zhuang Qianding briefly introduced the principles and contents of digging efficiency calculation.

"Good, good," the old leader praised the words repeatedly. He instantly understood the importance of the excavator to the troops. Such a high digging efficiency could essentially improve the combat effectiveness of the troops.

A brigade engineering company is equipped with four small excavators. It only takes one day to cooperate with the infantry to complete the brigade's field defense positions. The solidity of the positions is beyond the reach of manpower. In terms of roads, four excavators can be used to repair roads at the same time, which can ensure the high-speed movement of the main force and build new logistics supply lines.

The number of application scenarios is simply unimaginable.

Zhao Erlu asked, "By the way, can we add a shooting platform?"

"Of course, no problem. It can be equipped with two coaxial machine guns similar to those on a tank, and a layer of foldable 20mm bulletproof armor installed on the front. It can be put down when in use and folded when not in use. It can resist rifle and heavy machine gun fire." Zhuang Qianding said in a serious tone: "In addition, it can also be equipped with a thickened bucket to open up minefields for the troops, but it is vulnerable to attacks from Japanese grenade launchers and Type infantry guns."

"It's enough to be able to open a minefield. I can't bear to use such a treasure to charge head-on." The old leader nodded.

"Professor Zhuang, how can we transport it?" Zhao Erlu continued to ask, "Eight tons is not a small number. The Red Star tractor cannot pull such a heavy load on the open road."

"Don't worry about transportation. We can develop a new model based on the Red Star tractor platform for upgrading and modification. In terms of power, it will be equipped with a 100-horsepower diesel engine. The chassis will be enlarged and the cargo box will be lengthened and widened. The tires will be changed from single-bridge and single-wheel to double-bridge and double-wheel, with two in front and eight in the rear, a total of ten tires. There will be no problem in reaching a regular load capacity of 10 tons. As for the overload weight, it should be able to reach 30 tons." Yu Hua said with a smile, digging a hole again without any hesitation.

Anyway, he is leaving soon, and the research and development tasks will not fall on him. He has to leave more positions for his senior brothers who are nuclear-powered donkeys, and they cannot sit idle.

Zhao Erlu asked with concern: "Are there any difficulties in research and development?"

"no problem."

Yu Hua shook his head, changed the subject, and offered his own suggestions: "Regarding industrial equipment, I think in addition to excavators, we should also pay attention to the field of electronic technology. We should try our best to acquire electronic tube manufacturing technology and independently produce various types of radio equipment to make up for the shortcomings of the base in the field of communications. Whether it is information exchange between factories or military operations, radio stations are urgently needed."

"It may not be easy to obtain a complete set of electron tube manufacturing technology. The Soviet Union attaches great importance to the field of communications and will never allow the leakage of any technology in the electronic field. Before I returned to China, the Soviet Academy of Communications was developing a new generation of tank-mounted shortwave radio systems." Hearing Yu Hua's idea, Li Qiang shook his head slightly and gave an answer based on his experience of studying abroad at the Soviet Academy of Communications.

When it comes to radio and communications, this is Li Qiang's home turf. During his studies at the Soviet Academy of Communications Sciences, he understood very well how much importance the Soviet Union attached to the field of communications, especially the field of communications applications.

Even the oldest and most common electron tube manufacturing technology cannot be leaked to the outside world.

"It's okay. It would be great if it can be given to us, but if it can't be given to us, we can do it ourselves. Anyway, we should solve the problem first." Yu Hua smiled and said, "What if Comrade Stalin is in a good mood tomorrow and approves it for us?"

Comrade Stalin is in a good mood?

Everyone couldn't help laughing when they heard this, but it did make sense.

What if it really gets approved?

"Then I support it." Li Qiang immediately expressed his attitude.

"Okay, then we'll take the excavator and the full set of electronic tube manufacturing technology as the core projects. In addition, we'll pair it with a few equally important projects, such as the GAZ 5V car, the full set of drawings of the T-series tank engine, and the 100-ton hydraulic press to create a house-demolishing effect. Also, in order to avoid the Soviet Union's anger, we'll still have to add various old machine tools and forging equipment from the First World War to make them satisfied." Zhuang Qianding said solemnly and made a decision: "After all, these old machine tools can be transformed and upgraded into professional machine tools for ammunition assembly line production. The quantity should be large, and the initial base is set at units."

"I have no objection," Yu Hua responded.

Li Qiang nodded: "I support it."

Although the performance of old machine tools is backward, the actual effect is not bad. Transforming and upgrading them into professional machine tools can save a lot of time.

Don’t miss out on things from the Soviet Union.

The old leader and Minister Zhao Erlu had no objection to this decision. They respected and trusted every choice of the three-person expert group. The emergency meeting ended here, and the project on industrial equipment was decided. The Secretary-General carefully recorded each project and equipment, and checked carefully to confirm that there were no omissions before sealing it.

Immediately afterwards, a long, highly encrypted telegram flew towards the northwest at the speed of light.
