Chapter 1882: There are many minor problems

The torch was extinguished and placed back in the cab. The driver stepped on the clutch and put into gear. Then, he heard the sound of tires creaking idling.
Where is the front of the car? Although the engine was there, as he lifted the clutch, the front of the car began to sway upwards and even the front wheels left the ground.
He scratched his head again.
After all, the cargo compartments in the back are all full, or less to say, one hundred and fifty tons. In this case, the start is strenuous.
If you hit a relatively solid ground, you can still start, but now, the coal below here has become powdery. Starting at this time is quite difficult.
"Hey, come and pull it!" the driver shouted.
In addition to starting here, there is also the steep ahead!
A big pit has been dug out here. After all, there is a layer of soil on the coal, and the coal layer has a depth of excavation, so if he wants to go up, he can only climb up.
In this case, there will be a problem. Even if he starts here, he can't go uphill.
However, this does not trouble 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 of the truck also bears the weight of the cargo box, but the tractor is a full-trailer, and it can be separated from the cargo box by removing the hook on the back.
The waiting tractor saw his embarrassment and immediately reached out to help. The tractor driver came down, took off the hook at the back, disconnected the gas path, and then drove the front of the tractor to him.
"Come on." The middle of the two tractors were connected by a strong steel wire rope. Then, the two tractors worked hard together, and the cargo box at the back still didn't move amidst the tire slipping!
Shouldn't it?
The tractor driver in front came down, walked to the back, and squatted down to take a look, his face suddenly changed: "The brakes are frozen!"
At this time, the fourth child has also come over. Although he is very anxious and has invested such a big investment, he is waiting to pay back soon, but now, encountering these special circumstances, of course he has come over anxiously.
If the engine is frozen, you can still use a torch to bake it, 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 all air brakes. Only high-pressure air with a pressure of 10 atmospheres can stop hundreds of tons of vehicles. In fact, more than five vehicles can be stopped. Tons, air brakes have already started. Air brakes need compressed air. This air comes in directly from the outside. As we all know, there is moisture in the air.
This moisture will freeze inside the air path and then block the air pipe. In this case, the brake will fail.
Ordinary brakes are brakes. Compressed air passes through and enters the brake cylinder to provide braking force to the brake shoes. However, advanced brakes are already air-stop brakes. Simply put, when they are out of air, they are brakes. In the dead state, the brake will be released only when there is air. This is a safety measure. If the brake fails and there is no air in the air pipe, it can still stop.
But now, if the air pipe is not ventilated, it means that the brake cannot be released and the wheels cannot move. How can it be towed away?
"This car is so crude!" The driver in front looked at the back first, then at the front, pointing to the engine and said: "We don't even have a drying tank in this gas path!"
He used to drive heavy trucks in the north and was familiar with the structure of heavy trucks. Before entering the air pump, there was a drying tank in the air path to filter out the water vapor in the air to prevent the moisture from freezing in severe cold weather. Live, but now, this tractor does not!
The air path is complicated. It requires not only a drying tank, but also a spiral air pipe between the air compressor and the air tank, which can continue to condense the moisture in the air and then come out of the air tank. But now, everything is here. No!
Tractors don't need this thing, just a front, does not need much braking force, but if you add a trailer, it is different.
Normally, there will be no problems, but when using this thing on the cold grassland, the design flaws are magnified.
"Then what shall we do?" the fourth child asked.
"Now, the brake line has been frozen, we can only wait for it to melt at noon tomorrow."
"No, it's definitely not possible, it's a waste of time." The old fourth said: "Just release the brake manually and drag the car out first!"
At least we have to free up the working area here. Only this car is frozen. The other cars will continue to work. As for the technical details, the fourth child of course doesn't understand.
This is already produced by the well-known Yituo factory in China. Who would have thought that there would be these problems! In the field of heavy-duty trucks, the northern heavy-duty truck factory is unique. Many people buy the products of the northern heavy-duty truck factory even if they wait, even if they spend more money, because their products are excellent.
The products of other factories often have small problems. A small problem may have a big impact. Just like they are now, if you can’t release the brakes, you can’t continue to work.
The fourth child won't wait that long.
Manually adjust the brake drum, you can release it, but the car is completely out of brakes. After a while, when dragging uphill, if the power is insufficient and the car can't stop, it will definitely go backwards, which is too dangerous!
"Go ahead, listen to me," the fourth child said. After speaking, he pondered for a while and said: "You are done, and each will give you a bonus of 200 yuan."
At this time, they can only use money to lure them. In fact, aren't these people here for money? They all know in their hearts that what they are doing now is illegal. They want to mine the coal resources here without any formalities. However, they are willing to pay for the money.
"Okay, let's try." The driver in front said: "If there is a problem, jump off the car immediately. Don't hesitate."
This thing might be deadly, but it's not a joke.
The fourth child is frowning again, my car, you must protect my car. These cars are his capital. If they jump off the car, what should I do if the car breaks down?
No, you must protect the car, the big deal, I will give you another two hundred dollars.
At this moment, he felt the ground under his feet trembling slightly, and suddenly his expression changed.
This kind of ground shaking, there must be a convoy coming. He chose this place, which is quite hidden. Few people come. There is no road nearby. On the prairie, you don't need a road, just walk casually.
Now, who is coming here?
