Siheyuan Great Craftsmen

Two days later, the district government sent someone to inform the machinery factory that the design and planning of the high-rise building had been approved, which made Zhou Tian even more excited.

Especially regarding the power and water supply issues, the government has already contacted the construction department to start the renovation of the area around the branch, digging trenches, and laying pipelines and wires.

When the people at the machinery factory received the news, they were shocked by the government's high efficiency. However, since the construction machinery had not yet been completed, the construction of the family building had to wait for a while.

However, except for the concrete placing boom, Zhou Tian has already designed the rest of the construction machinery, and workers only need to process it according to the drawings to complete it.

The engine was naturally given to Zhang Min and his team. Although the engine they made at the beginning was not unusable, the excavator designed by Zhou Tian was a large engine, so naturally a more powerful engine was needed.

Moreover, after one study, Zhang Min and her colleagues have gained experience in engine research, so it is only a matter of time for them to develop a high-power engine.

Of course, Zhou Tian would definitely not let them waste time. As long as the concrete placing machine is developed, he would join in to speed up their research.

To put it simply, the working principle of a concrete placing boom is that when concrete is delivered to the entrance of the placing boom through a delivery pump or a pump truck, the concrete flows along the delivery pipe under the action of the conveying system inside the placing boom.

The control system is operated to extend and rotate the boom to the predetermined pouring position. Then, the distribution valve opens and concrete flows out from the outlet at the end of the boom and is evenly distributed in the pouring area.

The principle is not complicated, but it is not easy to develop a concrete placing boom in 53. First of all, in terms of materials, high-strength and corrosion-resistant materials are needed to ensure the reliability and service life of the equipment.

This kind of material alone has not appeared not only in China, but also abroad. If Zhou Tian did not have the material formula from his previous life, he would probably be powerless even if he wanted to research it.

The second is that the complex mechanical structure processing and parts precision control technologies required for manufacturing concrete placing booms are still difficult to master. The manufacturing of parts such as the boom structure, slewing device, hydraulic system, etc. of concrete placing booms requires high-precision processing equipment and advanced manufacturing technology.

This would have been impossible before Zhou Tian invented a series of machine tools. Although it may be difficult to achieve the same precision as in the past, it can be roughly manufactured.

Therefore, when Zhou Tian drew the concrete placing machine, ten days had passed.

During these ten days, Zhang Min and her colleagues had no idea about the design of the high-power diesel engine. As a last resort, Zhou Tian could only join in as soon as he finished the design of the concrete placing boom.

With Zhou Tian's guidance, the design of the high-power diesel engine was soon completed. This time, Zhou Tian not only increased its horsepower to 600 horsepower, but also reduced its size a lot.

Coupled with the use of new material aluminum alloy, it can be said that this diesel engine is enough to be ahead of the current world by about five years.

Although the engine has not been verified yet, Zhou Tian did not bother to verify it. He directly manufactured several units and used them in construction machinery. However, due to the existence of space, it was actually not important to him whether it was verified or not.

Early June, in the square of the machinery factory.

Rows of excavators, pile drivers, tower cranes, elevators, concrete mixers and concrete placing machines stood quietly in the square. The industrial beauty directly shocked every worker passing by.

Even many workers gathered around these machines, talking about them.

“Is this a machine made in our factory?”

A worker looked at the spectacular and shocking scene before him and couldn't help but ask his co-worker next to him. The shock in his eyes was simply beyond words.

"If it wasn't made in our factory, could it be made in another factory? Besides, in the entire city of Sijiu, apart from our factory, which other factory has such capabilities?"

Although the other worker's eyes showed no less shock than the other, he still suppressed his inner shock and asked back.

"It seems so. These huge machines are just too shocking. I wonder how the factory director and his team designed them!"

"I think I know this. Recently, the factory director has summoned many masters to work in Workshop No. 5. I guess they are manufacturing these machines!"

As the workers spoke, everyone was proud of such a scene. After all, such a scene could probably only be seen in a machinery factory.

"Everyone make way, the factory director is coming!"

While the workers were still discussing, a voice was heard outside, which immediately attracted the attention of the workers. When they looked in the direction of the voice, they saw Zhou Tian walking over with several deputy factory managers.

The moment everyone saw Zhou Tian, ​​they immediately moved to the sides and automatically made way for the factory director.

"Director, are these machines all developed by our factory?"

Zhou Tian was walking when a worker's voice suddenly sounded in the crowd, causing several people who were walking towards a group of construction machinery to stop in their tracks.

In an instant, all the surrounding sounds disappeared, and everyone turned their eyes to the factory director.

"It was researched by our factory!"

Zhou Tian met everyone's gaze and nodded affirmatively.

"Great! The factory manager is awesome!"

When the workers heard this, they were stunned at first, but when they got the factory director's affirmative answer, an indescribable surprise suddenly surged into their hearts, and several workers suddenly shouted loudly.

"The factory manager is awesome! The factory manager is awesome!"

The words of several people immediately aroused the echo of a group of workers, who shouted at the top of their lungs.

"Thank you everyone, please stop gathering together and go back to work!"

Zhou Tian waved his hand to stop everyone from shouting, turned around and gave Song Weiguo a few instructions, then brought four deputy factory directors to the construction machinery.

"Director, these construction machines look so spectacular when placed here!"

Even though Zhang Mingzhi watched the factory director draw it, he was still shocked when it all became a reality. This feeling cannot be expressed in words.

“Yes, it’s really spectacular!”

Jiang Long, Chang Weijun and Zheng Tianhua standing by also had eyes full of shock. They were all experts in the field of machinery, so naturally they found it extremely unbelievable that the factory director could design such engineering machinery.

You know, they are very clear that with the current domestic industrial level, it is basically difficult to develop such engineering machinery.

Not to mention other things, just some of the theories, materials and scientific designs involved are enough to make people collapse, but what do they see now? These construction machinery are just laid there nakedly.

Even though they had heard about the factory director's prowess in mechanics, they had never imagined he was so proficient. This was beyond their understanding.
