This design method is not available in all the excavation machinery in the world, because the traditional excavation equipment needs to be replaced manually, the speed is slow in all aspects, and the power that the hydraulic system can output is far less than the excavation equipment designed and produced by Huanyu Company. Pen & Fun & Pavilion www.biquge.info

Because the design of these hydraulic systems, as well as the manufacturing materials, and the manufacturing process, even those large international companies cannot produce.

For example, in order to make the entire hydraulic system have stronger strength, the metal materials used are made of special compression-resistant metals, and the highest and most compression-resistant ones are currently recognized as various grades of titanium alloys.

The price of different titanium alloys is also very different, and many of the outputs are relatively limited, if Yang Yu wants to buy top titanium alloy metal before, it is naturally very difficult.

But now he has 1 set of C-level material smelting equipment, which means that he is fully able to manufacture ready-made products of various titanium alloy technologies that he currently has mastered according to his own needs, and the cost price is very low, just counting the cost of various metal raw materials with a single attribute purchased from the beginning.

Therefore, this excavation equipment, in order to ensure that it can use super power, and the maximum power that the hydraulic system can output, its rectification hydraulic system is basically made of titanium alloy of various specifications.

At present, there are not many companies that can process titanium alloys, although those large companies in the world can process, but the difficulty and cost will be huge, and they will definitely not want Yang Yu to use it like this.

However, Yang Yu from the beginning of the purpose of manufacturing these heavy construction machinery is for his own use, even if he sells it in the future, he will not sell too much, and now he has set up a construction company, the purpose of which is to facilitate his future expansion of the factory, and the construction speed in all aspects is also faster.

In the past few days, his construction company has recruited a lot of employees, among which the drivers who drive construction machinery account for the majority, and there are also some engineering design and daily management personnel of the company.

After having his own construction company, Yang Yu's projects for the expansion of the new factory contracted to the original two construction companies have also decreased a lot, and they are basically asked to provide labor in terms of labor.

Any large construction machinery that is needed in the construction process will be responsible for Yang Yu's own construction company.

Because no matter what kind of construction machinery, as long as there is a demand, Yang Yu's factory will soon be able to design and manufacture, and the performance in all aspects is much stronger than those factory machinery on the market.

Originally, after Yang Yu had his own construction company, he could not need the two construction companies to be responsible for anything at all, but he also had a pleasant cooperation with the two companies, and this time he was busy with the design plan at the beginning, and the two companies were state-owned construction units, so since Yang Yu had already let the family do it at the beginning, it was not good for him to set up a construction company and let them withdraw at once.

In addition, the two companies have a huge advantage in the supply chain of the entire construction industry, and if Yang Yu wants to build the building quickly, these subsequent building materials must also be fully guaranteed.

At this moment, after the groundbreaking ceremony was completely over, Yang Yu gave an order, and all the excavators went to the corresponding area to start working.

And at this time, the performance of these excavators was immediately displayed.

"Oh my God, this excavator feels so easy to go down, and the engine noise is nowhere near as loud as other machinery, the sound is very low, and the horsepower is absolutely full. ”

"Yes, this excavator is really awesome, and Huanyu Company is really implementing their quality-oriented, practical and efficient style as always!"

"I heard that Huanyu Company has two family cars to hold a new car launch conference in a few days, and I must go to see it then. ”

"Yes! Since the bicycles and motorcycles produced by Huanyu are so powerful, and now even heavy machinery can be produced, then the family car must not be bad. ”

These people who came to participate in the groundbreaking ceremony at this moment have seen the efficiency of these construction machinery with their own eyes, and the previous suspicions naturally no longer exist.

At this time, the heads of the previous two construction companies also found Yang Yu at the same time and said.

"Mr. Yang, the performance of this 'Julingshen' series W1 excavator produced by your company is really excellent in all aspects, but I don't know when your company will sell it to the outside world?"

"Mr. Wu, Mr. Li, to be honest, our company's main goal at present is to produce family cars first, and the manufacturing cost of this heavy machinery is not low, so there will be no plans to manufacture heavy machinery on a large scale for the time being. However, if Mr. Wu and Mr. Li are interested in your group, I can give the W1 excavator to the two at a preferential price of 5 million, of course, in terms of time, it may take some more time. ”

Now Yang Yu has 500 sets of excavation equipment, but these are his own use, now the construction site is only a few dozen over, the next week 500 excavators and a large number of other projects will enter the site one after another, and then start work together.

Because the expansion of the factory can have at least 300 million m² of earthworks, and according to the workload of the Djinshen W1 excavator, it can work between 10,000 and 20,000 m24 hours a day.

The reason why there is such a big difference is mainly because the excavation speed of pure earthwork and the area doped with stones is different, and it is impossible for a machine to work continuously all day, and there will be a lot of delay during the period, and it is already very high to have such a large amount of 24 hours a day.

According to the calculation of such a project quantity, it will take at least 1 to 2 months to complete all the earthworks of 300 million m² and 500 excavation equipment working 24 hours a day.

This speed is naturally many times faster than the speed reported by the two companies to Yang Yu before, because if the two companies want to have Yang Yu's speed, they must mobilize thousands of excavators at the same time to work together 24 hours a day to complete such a fast earthwork.

Because the capacity of the normal excavator bucket is much smaller than that of the W1 excavator, and the speed and strength are also very different, the most important thing is that the stability of the performance is not comparable at all, and there will definitely not be a few breakdowns halfway.

However, Yang Yu is now using all new equipment, and the quality and working performance are very strong, as long as the oil is changed after the specified working time, and it is not the equipment that has been used for several years, the possibility of breaking down halfway is extremely low.
