Super Weapon Swap System

Put out the torch and put it back in the cab. The driver stepped on the clutch and put it into gear. Then, he heard the sound of tires creaking idling.

Where's the front of the car? Although there was an engine there, as he lifted the clutch, the front of the car began to roar upward, and even the front wheels left the ground.

He scratched his head again.

After all, the rear cargo compartment is full, at least 150 tons. In this case, it's hard to start.

If you encounter a relatively solid ground, you can still start, but now the coal below here has become powdery. It is quite difficult to start at this time.

"Hey, come and pull it!" shouted the driver.

In addition to starting here, there is also the steep slope ahead!

A big pit has been dug out here. After all, there is a layer of soil on the coal, and the coal layer is also deep. Therefore, if he wants to go up, he can only climb up.

In this case, there will be a problem. Even if he starts here and goes uphill, he can't go up.

However, this is not difficult for him. For tractors, this situation is often encountered and it is easy to solve.

Pull it!

The heavy truck is a semi-trailer, and the front also bears the gravity of the container, but the tractor is a full trailer. As long as it takes off the hook at the back, it can be separated from the container.

The tractor waiting on the side saw his embarrassment and immediately extended a helping hand. The tractor man came down, took off the hook at the back, disconnected the air circuit, and then drove the front of the tractor to his front.

"Come on." in the middle of the two tractors, they were connected by a strong steel wire rope. Then, the two tractors worked hard together. In the sound of tire slipping, the container behind still didn't move!

Shouldn't it?

The tractor driver in front got down, went to the back, squatted down and looked, and his face suddenly changed: "the brake is frozen!"

At this time, the fourth has also come. Although he is very anxious and has so much investment, he is waiting to return to his capital early, but now, in these special circumstances, of course, he comes restlessly.

If the engine is frozen, you can bake it with a torch, but if the brake is frozen, it will be troublesome!

The cold in prairie city is quite unfriendly to vehicles. The brakes of heavy vehicles are air brakes. Only high-pressure air of 10 atmospheres can stop hundreds of tons of vehicles. In fact, when the car exceeds five tons, it has begun to be air brakes. Compressed air is required for air brakes. As we all know, the air comes directly from the outside, There is water in the air.

This moisture will be frozen inside the air circuit, and then the air pipe will be blocked. At this time, the brake will fail.

The ordinary brake is to step on the brake, and the compressed air enters the brake cylinder to provide braking force to the brake shoes. However, the advanced brake has been cut off. In short, the brake is dead when there is no air, and the brake will be released when there is air. This is an insurance measure. In case the brake fails and there is no air in the air pipe, It can also stop.

But now, the air pipe is not ventilated, which means that the brake cannot be released and the wheels cannot move. How can they be towed away?

"This car is so simple!" the driver in front looked at the back first, followed by the front, pointed to the engine and said, "we don't even have a drying tank in this gas circuit!"

In the past, he drove a heavy truck in the north and was familiar with the structure of the heavy truck. In the air circuit, there was a drying tank before entering the air pump to filter the water vapor in the air to prevent the water from freezing in cold weather, but now, this tractor doesn't!

The air circuit is complex. There is not only a drying tank, but also a spiral air pipe between the air pump and the air tank, which can continue to condense the water in the air and then come out of the air tank, but now, there is nothing here!

The tractor doesn't need this thing. It only needs one head and doesn't need much braking force. However, it's different with the trailer.

In normal times, there will be no problem. However, on the cold grassland, when using this thing, the design defects are amplified.

"What shall we do?" the fourth asked.

"Now, the brake pipeline has been frozen. We can only wait for it to open at noon tomorrow."

"No, that's absolutely not. It's a waste of time." the fourth said, "simply release the brake manually and drag the car out first!"

At least make room for the working face here. This car is the only one frozen. Other cars have to continue to work. Of course, the fourth doesn't understand the technical details.

This has been produced by the famous Yituo factory in China. Who could have thought that there would be these problems! In the field of heavy trucks, the North heavy truck factory is unique. Even if many people wait and spend more money, they also want to buy the products of the North heavy truck factory because their products are excellent.

The products of other factories often have small problems. A small problem may have a great impact. Just like now, if they can't release the brake, they can't continue to work.

The fourth won't wait that long.

Manually adjusting the brake drum can release it, but the car will not brake at all. After a while, when towing uphill, if the power is insufficient and the car can't stop, it will definitely go backwards. It's too dangerous!

"Go ahead and listen to me," said the fourth. Then he thought for a while and said, "when you're done, each of you will give you a bonus of 200 yuan."

At this time, we can only lure them with money. In fact, these people come here just for money? They all know that what they are doing now is illegal. They wantonly exploit the coal resources here without any formalities. However, they are willing to give up for money.

"OK, let's try," said the driver in front. "If there is a problem, jump immediately. Don't hesitate."

This thing may die. It's not for fun.

Old four frowned again. My car, you must protect my car. These cars are his capital. If they jump, what if the car breaks down?

No, you must protect the car. If it's a big deal, I'll give you another 200 yuan.

Just then, he felt the ground under his feet trembling slightly. Suddenly, his face changed.

This kind of ground vibration must be that a motorcade is coming. He chose here, which is quite hidden. Few people come here, and there is no road nearby. On the prairie, there is no road, so he walks casually.

Now, who's coming?
