Chapter 446: Which company has the best excavator technology (Fourth update, please subscribe)

What are the requirements?

After hearing this, Li Yi'an's mind flashed to a very common construction machinery from another era.

And it’s almost every boy’s favorite – the excavator!

Recalling that in later generations a boy could lie there and look at the excavator for a whole day, Li Yian thought about it and replied:

“First of all, in infrastructure projects, there is a lot of excavation work, such as digging building foundations and organizing river channels. Although we have also invested in some electric shovels, most of these earthwork operations rely on manpower. After all, electric shovels are not only heavy, but also It moves clumsily and is not suitable for ordinary earthwork infrastructure construction.”

While recalling its specific structure, Li Yian walked to the drawing shelf, picked up a pencil, and began to draw a sketch of the wheeled full-rotation hydraulic excavator based on his memories.

“First of all, the arm of this backhoe excavator must be long enough, and the fuselage can be fully rotated. In this way, during earthmoving operations, the rotating bucket can be used to load the dirt onto the truck, and the Driving in non-paved areas, you need to have certain off-road capabilities. Well, considering the rotation of the power cabin and the arm, hydraulic transmission can be used. Secondly, its bucket must also be hydraulically directly driven, rather than relying on The machine arm pushes..."

This series of requirements is obviously not low, especially hydraulic transmission, which is definitely the most advanced technology in this era, but Li Yian believes that it is not impossible. At least there will be no problem in hydraulic excavation.

After all, they have already figured out the hydraulic rod on the heavy mine car. The technologies between them are somewhat related, and all they need is a directional reminder.

Li Yian pointed at the sketch and said.

Hearing the compliment, Li Yian coughed lightly and said:

It took Li Yian more than half an hour to draw the structural sketch of the excavator arm based on his memory. After putting down the pencil, he looked at Schwart who had squeezed aside and asked.

Looking at Li Yian with some surprise, Schwart said:

"Sir, you know what? You have pointed out a new direction for the application of hydraulic technology. My God, hydraulic technology will be more used in a wider range of fields."

"How about it? Do you find it difficult?"

Schwart obviously didn't expect that hydraulic technology could be used in such a combination, at least he hadn't heard of it yet, but in many cases, technical matters are often just a layer of window paper.

On so many construction sites, at least 500,000 to 600,000 people are engaged in this kind of heavy manual labor. With excavators, only a few hundred excavators are needed to replace their jobs.

Hydraulic excavators are absolutely of great significance to the earthmoving industry. The manpower they can save is unimaginable - manual digging can only dig about 5 cubic meters a day, but for an excavator with a 0.5 cubic meter backhoe, Said, this is just a matter of a few shovels, well, it only takes a minute or two. An excavator can excavate four to five thousand cubic meters of earth a day, which is almost equivalent to the workload of a thousand people.

The engineers gathered around and carefully observed the sketches drawn by Li Yian. Although it was just a sketch, through his description, they quickly understood his idea.

Li Yian, who was afraid of scaring them to death, recalled it and drew a diagram of the loader on the drawing. Compared with the full-rotation hydraulic excavator, its structure is simpler. It only took ten minutes to draw the sketch. .

"Hydraulic technology can be applied not only on excavators, but also on loaders. Loaders. Today's loaders are all modified from tractor chassis. They have front engines, small front wheels, large rear wheels, and single-axle front-axle drive. , front-wheel steering, gantry-type working device, wire rope lifting arm dumper loading and unloading equipment, small bucket cutting force, low operating speed!”

How many workers are currently engaged in earth excavation work at construction sites in Nanyang?

"With hydraulic technology, the lifting speed, unloading height, breakout force and cutting force can be increased, so it can be used to shovel loose earth and stone. Well, technically speaking, it is simpler."

"Difficulty?"

"It's actually possible to do this, through multiple combinations of the hydraulic system, using hydraulic power to complete the excavation work..."

After painting, call it a day.

"It's technically simpler!"

Schwart didn't know how to describe his mood at this time. As for the engineers around him, they were all silent as they looked at Li Yi'an, a president who was accomplished in physics, aeronautics and other fields.

As for Wu Liren and other assistant engineers who graduated from various universities in Nanyang, there is only one sentence left in their hearts - "Idiot!" Is this the so-called "knowing it from birth"?

Others can invent a full-rotation hydraulic excavator, even if it is just an idea, it is not easy, but this man actually created a hydraulic loader.

And it’s less than a minute apart!

Even in just a few dozen seconds, this man had already invented a new invention. How much knowledge does he have in his head?

No, it should be said, is there anything else in this world that he doesn't know how to do, that he doesn't understand?

"How about it, there is no technical problem!"

Li Yian asked again.

Facing your inquiry, Schwart also nodded calmly and said:

"Yes, there is no technical problem at all. Our hydraulic technology is still very mature. Although there are some difficulties with the full-rotation hydraulic excavator, with the design principles, I believe that we will soon be able to design an excavator that meets your requirements. , I think two project teams can be set up, one to study full-rotation hydraulic excavators, and one to study hydraulic loaders."

Although Li Yian feels that the full-rotation hydraulic excavator may not necessarily make a breakthrough in the short term, he knows that once it makes a breakthrough and is mass-produced, how much labor will be released, it may not be hundreds of thousands, but millions, or even more. .

Moreover, full-rotation hydraulic excavators and hydraulic loaders have very broad overseas markets. After all, the reconstruction of Europe is still on the way. In the next twenty or thirty years, it will be an era of large-scale infrastructure construction in Europe. In this kind of Under such circumstances, their demand for excavator and loader-level machinery and equipment is conceivable.

In particular, the market space for loaders is so large that it is simply beyond people’s imagination.

A loader is actually a forklift, the most common mechanical equipment in engineering operations.

When many people mention construction machinery, their first impression is often of excavators. After all, Mr. Tang’s advertisements are so hard-core that people all over the country know which excavator is better.

Moreover, the boys' love for excavators has also made them popular and they have become stars in construction machinery.

However, the application of loaders in engineering is no less than that of excavators. During large-scale infrastructure construction, the use of loaders even far exceeds that of excavators.

The main purpose of an excavator is to dig and move large objects. The loader's main functions include shoveling, loading, unloading, and transportation. It can also perform excavation work on the horizontal surface.

If you are building high-rise buildings or digging foundations for factories, excavators are definitely better, but if you are working on flat ground, then loaders dominate.

In construction projects such as roads, railways, ports, mines, and water conservancy projects, loaders are used far more than excavators.

The 1950s to the early 1980s was the era of large-scale highway construction in European countries. In this era, even Western Europe's transportation infrastructure was very poor. The large-scale infrastructure construction after the war in various countries was mainly based on the construction of roads.

As for the United States on the other side of the ocean, the same is true. Especially during the Eisenhower era, the United States launched large-scale infrastructure construction and built many interstate highways. In the following few decades, the total number of highways at all levels was built. Millions of kilometers.

Road construction will inevitably use a large number of loaders.

Such a big market is now in front of Li Yian, and of course he will not give up.

Moreover, construction machinery is also a durable industry. As long as the country's infrastructure construction continues, construction machinery will not have to worry about lack of sales.

At the beginning, it was Nanyang, Europe, and the United States. After they completed their infrastructure construction, it was the turn of emerging markets such as Southeast Asia and South America, and then Tangshan.

The vastness of this market is definitely beyond people’s imagination!

Now that he has this opportunity, Li Yian naturally wants to give it a try. Of course, the most important thing is to liberate Nanyang's labor force and use as much labor force as possible in industries with higher output value.
