Chapter 66

A group of new students are still in their own aftertaste, where Ni Jiaqiang has closed the computer.

"Why do you have to go back to learn this history by yourself.

Now, taking advantage of everyone's presence, I'll give you a basic course on excavators, and I'll arrange the learning tasks for the first month of this semester.

Come with me

Ni Jiaqiang said and walked out of the classroom, a group of new students quickly followed out.

Before long, Ni Jiaqiang took all the people to an open space.

There is a three meter high and six meter long medium-sized excavator in the open space. The excavator body is black, and the bucket and mechanical arm are slightly white. It looks very new.

Many freshmen can't move their eyes after taking a look. This kind of novel excavator is quite different from the excavator driven by ordinary people in the city.

Ni Jiaqiang went to the excavator and lifted the whole excavator with one hand.

"This excavator weighs only five tons, but it can burst out 50 tons of strength. Under certain specific circumstances, its role is greater than that of a red fog fighter with hundreds of combat power. This is the significance of the existence of advanced excavators.

Let me first introduce the components of the excavator to you... "

With that, Ni Jiaqiang began to introduce the basic structure of the excavator part by part.

About five minutes later, he stepped aside.

"Go and see for yourself."

As soon as these words came out, many freshmen immediately gathered around the excavator and began to observe this special excavator closely.

……

"I'll go! Carbon fiber fuselage! How much is this special? "

Wu ideal touched the black fuselage of excavator lightly, startled voice sighs a way.

He Mu was also surprised to hear that he had studied cars in his previous life and knew the value of carbon fiber.

Although the price of carbon fiber in this era is much lower than before, it is still very expensive.

Before the meteorite calendar, the price of an all carbon fiber sports car was about tens of millions.

Now it has to be sold for nearly ten million.

Who would have thought that this material was used on the excavator.

Before the meteoric calendar, I didn't even dare to think about it. I can't recover the cost of digging the excavator.

"The chassis, bucket and key parts are made of bone alloy. No wonder they are so light but can bear 50 tons of force!"

Another student exclaimed.

He Mu also went to the bucket at this time. The bucket was gray and felt like bone alloy.

Bone alloy is a new kind of material, which is made of some kind of monster skeleton and aluminum alloy. This material is lighter than steel and heavier than aluminum alloy carbon fiber.

But its strength and hardness are far higher than those of traditional materials such as steel, aluminum alloy, carbon fiber and so on.

Judging from the strength and structure of the manipulator, I'm afraid it can really withstand the force of 50 tons.

Also, the chassis of this excavator seems to be quite special. There are many small holes around it.

He Mu a little thought to know the role of these holes.

The excavator weighs five tons, and if the five ton excavator really burst out with 50 tons of power, its fuselage would inevitably be tilted up. These small holes are supposed to be used to grab the ground, but how to work is unknown.

……

"The manufacturer of this ordinary mining type B excavator doesn't make money. The cost price is about 8 million yuan. Its service life is estimated to be 15 years. If you work every day, you can recover the cost for more than two years. If you rent it, it will be 5000 days."

See a group of new students around the excavator research, Ni Jiaqiang stood aside and said with a smile.

Listening to this, all the freshmen are thinking about how long they can earn such an excavator.

"Keep looking. I'll get a car."

Ni Jiaqiang then turned and walked away.

As soon as he walked away, a group of new students became nervous and began to study the excavator recklessly. Some even climbed between the tracks of the excavator and began to observe the chassis.

At this moment, a slightly rough voice sounded nearby.

"What's special? Your name is Wu ideal?"

He Mu listened to this to turn head to see past.

I saw that the only girl in the class was standing in front of Wu ideal, holding his collar, and her expression was not good.

Looking at the girl who is half a head taller than himself and twice as big as himself, Wu ideal also trembles. But when so many students look at him, he can't beg for mercy. He can only say, "what are you doing! According to the school regulations, it is not allowed to beat classmates! ""I know that you have to force me in the canteen at noon, don't you? I tell you, my name is you Dazhi! My ears are very good! I'll force Lai Lai later, otherwise I'll blow your dog's head! "

After that, you Dazhi made a sudden effort to lift Wu ideal over his head and turn it seven or eight times. This scene made all the freshmen around gape.

"What are you looking at? There is no rule in the school that students are not allowed to be promoted! "

You Dazhi stares at the people around him, and then puts down the completely ignorant Wu ideal.

"I'm sixty-five combat effectiveness, and I'll be the monitor of the class from now on. Don't you mind?"

All the freshmen were a little afraid when they heard about 65's combat effectiveness, but some were skeptical.

After all, 65 combat effectiveness to vocational schools, that is not wrong?

As a result, you Dazhi went directly to the excavator, put his hands around the excavator, and then gave a loud drink!

"Get up!"

In a flash, the whole excavator lifted off the ground!

Seeing such a scene, all the freshmen couldn't help stepping back two steps and didn't dare to say no.

As far as you Dazhi is concerned, there is no problem for one person to beat a group of them.

He Mu is looking at silently beside, also have no opinion.

No matter what position, small to monitor, big to national leadership, that is to do things, to take responsibility.

It's not that he's afraid of taking responsibility, but that he can't find the energy to do anything else at this moment.

……

Before long, a square car came in the distance. There was a very obvious word "Jiao" on the license plate of the car.

When the car stops, Ni Jiaqiang gets out of the car and takes a look at you Dazhi.

When you Dazhi saw this, he put down the excavator.

Looking at you Dazhi like a huge mountain, Ni Jiaqiang sighed: "Dazhi, you're old and big. It's time to pay attention to your image."

"Teacher, what I have is not fat, but muscle! Look

You Dazhi rolled up his sleeve, revealing a strong and huge muscle mass.

Seeing this scene, Ni Jiaqiang's wrinkled cheeks twitched and turned to other freshmen.

"Your first month's task is to learn to drive and get your driver's license.

After all, wherever excavators go in the future, they will basically be transported by truck. "

As soon as he said this, you Dazhi said: "teacher, can't I carry it? It's a waste of time to learn how to drive. Just learn how to excavate. "

Ni Jiaqiang glanced at her and said: "you are walking on the road with an excavator every day. Are you in a hurry?

Even if you need to take the excavator in case of emergency, don't you still have to carry it to the truck in the end? "

"Well, that seems to be the truth." You Dazhi scratched his head and went back.

Other people have no opinion.

After all, as a man, how many people don't like cars?

But the state has regulations, under the age of 18 can not drive.

After the college entrance examination, they are all 18 years old, so they can take advantage of the summer vacation to get their driver's license.

However, after the end of the college entrance examination, the deadline for filling in volunteers is around the middle of August.

So during the summer vacation, almost all the red fog fighter students are trying their best to improve their combat effectiveness in order to apply for a better university. No one has time to learn a driver's license.

……

When the crowd calmed down, Ni Jiaqiang drew a box on the road.

"Today's first lesson, let's learn how to put the car in reverse first."

Having said that, he stretched out his hand in the freshmen group, and seemed to be deciding who to teach first, from point to point, and finally, on he mu.

"He mu, you come first."
