Chapter 1881

"Di, di!" the excavator sounded two horns.

As long as it takes several times, you can get familiar with it. The excavator master will press it twice. When the empty car comes and falls in the most appropriate position, he will sound the horn. At this time, it means that the empty car stops in place.

Of course, there is something particular about this. The empty car parking position should be several meters away from the excavator, but it should not be too far. For example, the left side of the excavator is the working face and the right side is the truck body. In this way, the excavator can perfectly reach both sides by turning a circle, which requires skills.

After loading, ring twice, which means the car can go.

In that year, Qin Guan completed the research and development of the new heavy truck project. Other truck factories were completely jealous and asked to share technology. Later, Yituo also set up a heavy truck alliance, and Yituo wanted to take a share. After all, Yituo had its own advantages. The first tractor, the first roller and the first military off-road vehicle came from Yituo.

The name of Yituo Dongfanghong is even louder, but in the end, they didn't get the results they wanted. Under the suggestion of Qin Guan, they produced a series of modified tractors. Yituo didn't share the heavy truck market, but took its own path.

Their tractors also grow as they are produced.

When it comes to tractors, it's easy to think of small four-wheel diesel engines with more than ten horsepower, which can be owned by farmers themselves and work in their own fields. If this kind of tractor is used, it can pull only one or two tons of goods.

This is certainly not in line with Yituo's appetite.

The tractors produced by Yituo are also getting bigger and bigger. Soon, they developed dongfanghong-1000 tractor. This kind of tractor is simply robbing the business of heavy truck factory!

This kind of tractor was produced in a hurry at the beginning, so it was simply improved on Dongfanghong 802 crawler tractor. Its biggest change is to use lr6105t9 engine with good economy and 100 hp engine. That's the name of 1000.

It looks like a tractor. The front engine, the small front wheel and the big tread main tire are behind it. Because of the large space, the driver in the middle has enough space, and even can have a sleeper in the back.

As like as two peas, the tractor is found to be in the market place immediately after its appearance. In many areas, the heavy trucks are in short supply and many people can't buy them. Moreover, heavy trucks are too expensive. Compared with that, tractors are much cheaper. Although the price is low, the performance is not bad at all.

Pulling goods in rural areas is often hundreds of tons, and there is no need for the formalities and expenses of cars. Only a Book of agricultural machinery is enough, and there is no need to worry about the fines of traffic police. It is simply a sharp tool to make money!

The investment is small and the cost is fast. Although it is not a heavy truck, it has the same carrying capacity as the heavy truck. When the Dongfanghong tractor hauling 100 tons of stones, sand and other goods comes, the sound is too shocking. The six cylinder diesel engine is roaring and struggling. Especially when going uphill, the speed is like a snail climbing a tractor, Don't hurry.

YITUO succeeded in the dongfanghong-1000, the products sold well all over the country, and even caused other tractor factories to follow suit, and they also made persistent efforts to improve this kind of tractor again.

The 100 horsepower engine can no longer satisfy them. They have purchased the heavy truck engine from the outside. Yes, it is the mainstream 240 horsepower diesel engine. At the same time, the gearbox has been upgraded from the previous five speed gearbox to the nine speed gearbox with high and low gears. The rear axle has also been upgraded to the wheel reduction axle dedicated to heavy trucks, It is no longer a single tire for agriculture, but a twin tire like a heavy truck. The whole power chain is completely the same level as the heavy truck.

According to the previous number, this tractor has become dongfanghong-2400. After it came out, although the price has increased a lot, it has been welcomed by many people. This thing is a substitute for heavy trucks. Anyway, the domestic freight market is not full, and there are no heavy truck manufacturers and users to protest against the rush to buy and sell.

Now, the old four bought this kind of tractor. It's also very exciting to run, and it's also on the license plate. It's the license plate with the special grassland nationality logo. If the police see it, they will never mind their own business.

The tractor is very tall. The reflector supports on both sides are far out. You can clearly see the back of both sides, which is no different from the heavy truck.

After hearing the sound of didi and Didi, the tractor driver turned the key of electric start.

"Hum, hum." the sound of starting the motor came from the front. The exhaust pipe was facing the sky. You can see the outside from the cab, and the exhaust pipe didn't smoke!

After a few times, the driver released his hand and couldn't start all the time. Otherwise, the circuit would be overloaded.

The driver was stunned, and his heart began to get up and down. After waiting for a minute, he turned the key again, and the weak sound of starting the motor came from the front.

"No, I can't start!" said the driver.

In cold weather, diesel engines often encounter some problems, and failure to start is the most common.

In the severe cold, the power of the battery will also weaken. He only ignited twice and saw that the battery alarm light had been on. He knew that he couldn't ignite again. He had to wrap his coat tightly and come out from the inside.

Fortunately, a big pit was dug out here, without the biting cold wind above. What's more, the tractor engine is at the front, which doesn't need to support the cab like a heavy truck.

Now the engine can't start. It's usually because the weather is too cold. He shivered down the cab, took out a torch from inside, lit it with a lighter, and began to bake the car.

Diesel oil contains water, which is a by-product of crude oil smelting. In severe cold, the water in diesel oil will condense and become waxy. At this time, there will be no fluidity. Of course, if inferior fuel is added, it will even freeze into ice.

Looking at the fire here, the excavator driver can only wait temporarily. Just at this time, he also has a rest.

There is also a need to pay attention to the fire. The external flame of the torch should be used to heat the oil circuit of the engine from the oil tank to the high-pressure oil pump. Among them, the diesel filter is the most easily frozen. If it is to be disassembled now, it may be a lump inside. After baking for a few minutes, he put down the torch, put it aside, jumped into the car, took a deep breath, and started again. This time, the front is still buzzing. Fortunately, the exhaust pipe has begun to emit black smoke. There is hope, continue, continue! His right foot kept stepping on the accelerator. Suddenly, the engine started!
