When it comes to the polar expedition team, everyone's first impression is the base expedition team members wearing thick special cold-proof down jackets and goggles, facing the biting cold wind of the polar region, the scene of the difficult trek forward, or riding a large group of sleds pulled by the Ekismo dogs on the boundless snow, anyway, it is a very mysterious feeling, and everyone is naturally curious about mysterious things.

"It's just some cars, what policy is violated? It's all something that everyone knows, and there's nothing that can't be said," Team Leader Jin smiled and waved his hand, "Our country uses the PB240 snowmobiles from Kesbauer, Germany, at the Great Wall Station and Zhongshan Station in Antarctica, two for each scientific research station, as well as a number of towed sleds for equipment and materials, and several snowmobiles purchased from Russia and modified. ”

"Zhongshan Station and Great Wall Station, there are only four snowmobiles in the two scientific research stations?" Someone exclaimed.

"This kind of snowmobile is very expensive," Team Leader Jin was not angry, and explained to everyone, "This is the situation of our country, because the economic conditions of our country are limited, so we can only do it, and other countries use most of the PB240, PB280, PB300 or American Carter. Most of the Challenger series snowmobiles are Challenger MT865, in fact, these cars are basically tractor-modified, such as the American Carter. The Challenger MT865 series produced by Beeller is based on a large American tractor,"

"There are also trucks or vans, but most of them have their tires replaced with special tracked mobility devices for snow walking, and of course there are cars that use pure snow tires, but very few, even trucks or other vehicles. They have also been changed to snow rubber tracks, wheeled vehicles are not easy to use in Antarctica, the grounding area is too small, easy to slip, not to mention, not to mention, it is not convenient. ”

"Team Leader, let me ask, how much is the PB240 snowmobile used by Kesbauer in Germany? How is the performance of this car? Lin Hongfei asked.

Boss Lin has "ulterior motives", according to the price and performance of PB240, he can also have an accurate "market positioning" for his products. ”

Team Leader Jin didn't know that Lin Hongfei's question was so "ill-intentioned". Lin Hongfei was just curious, and when he heard this, he immediately said, "PB240 is the most used and cheapest snowmobile used by scientific expeditions from various countries in Antarctica, with a weight of more than 5 tons. It can tow 25 tons of material, and a knuckle boom crane with a loading and unloading capacity of 2 tons can also be installed. The price is more than 5 million; PB300 is more powerful. With a self-weight of 7 tons, it can tow 35 tons of goods and more than 8 million vehicles; But with the American Carter. Compared with the Pile Challenger 865, the PB240 and PB300 can only be regarded as a drop in the bucket, the Challenger 865 weighs 223 tons and has an engine of more than 400 horsepower. It can tow a weight of 60 tons, in addition to being equipped with a 6-ton knuckle boom crane, Haier can be equipped with engineering front shovels, front buckets, and snow lifters, and the whole is a pioneer. However, the price is more expensive, the basic type will cost more than 12 million, and all the supporting systems will be fully matched, almost 15 million. ”

"So expensive?"

"How is that possible?"

"It's so expensive......"

Everyone exclaimed.

"How is that possible? How could it be impossible," Team Leader Jin smiled bitterly at Minister Chen's words, "This is the Germans and Americans who see that we can't build this kind of snowmobile that can withstand the cold by ourselves, and kill us to death, in fact, the Americans buy a Carter themselves. The Pile Challenger 865 is only less than 300,000 US dollars, which is converted into RMB and 2.5 million, but there is no way for us to make it impossible to produce it ourselves. ”

"Of course, in addition to these cars, there are also modified Swedish BV206 all-terrain vehicles that can adapt to the extremely low temperature climate of Antarctica, of course, the price is not cheap, it is said to be more than 5 million, but the towing capacity of this car is too small, it can only tow less than 10 tons of things, the price is okay PB240 is about the same, and there are relatively few countries to use, even if it is useful, it is also used as a crew commuter car for personnel."

Speaking of this, Team Leader Jin paused slightly, turned his head to look at Lin Hongfei and said, "Mr. Lin, I think you also know about our country's purchase of a 10,000-ton icebreaker from Ukraine this year, right?" ”

Team Leader Jin seemed to be looking for something to say, and deliberately found a topic to ask Lin Hongfei.

"Zhilu said, Team Leader Jin, you are talking about the 'Snow Dragon' polar ocean-going expedition icebreaker, right?" Lin Hongfei nodded.

The "Snow Dragon" polar ocean-going expedition icebreaker is the third generation in the world, and it is also the most advanced ocean-going icebreaker research ship in the world, which was originally built by the Soviet Union for its own use, but it was not thought that before the ship was built, the Soviet Union suddenly hiccuped, and our country purchased it from the Kherson shipyard in Ukraine at a low price of 17.5 million US dollars, and then the shipyard was renovated and completed in March 1993 according to the needs of China.

The performance of this ship is very awesome, with a full load displacement of more than 21,000 tons, a cruising range of 19,000 nautical miles, two helicopter hangars and a helicopter landing pad, which can continuously break through 1.2 meters of ice with a speed of 1.5 knots and 0.2 meters of snow.

Speaking of which, on the Xuelong base ocean-going research icebreaker, we made a big bargain, this is an ocean-going icebreaker that can reach the B1 level icebreaking ability, the market price of the same type of ocean-going icebreaker research ship will not be less than 80 million US dollars, we only used 17.5 million US dollars to buy it, although it cost more than 30 million RMB for modification after buying it back, but no matter how it is calculated, it is a big profit.

Since the Snow Dragon was put into service, the Antarctic and Arctic scientific expeditions and supply transportation tasks carried out by the Republic have all been entrusted to the Snow Dragon, and this ocean-going icebreaker can be called a meritorious ship of the Republic's polar scientific expeditions.

If I remember correctly, the Snow Dragon's maiden voyage to the South Pole will be in October next year, and the trip of the team leader is to find a snowmobile for the Snow Dragon that can replace the Keith Bauer PB240?

"That's right, even if it's the Snow Dragon, but Mr. Lin, you may not know very well, there are only three Kesbauer's PB240 snowmobiles on the Snow Dragon, it's not that we don't want to have more, it's just that this car is too expensive, and our country is too poor to afford it." Speaking of this, Team Leader Jin looked at Lin Hongfei with a deep face...... Lin Hongfei is not stupid, but how stupid is Team Leader Jin?

"Since Team Leader Jin has said this to this point, you can't pretend to be stupid." Lin Hongfei made a bitter face, spread his hands, and said.

Everyone suddenly laughed: Isn't it, it is also a very pleasing thing to watch Team Leader Jin put Lin Hongfei and Lin into a small cloth bag in front of everyone.

Team Leader Jin was also laughing, and after laughing, Team Leader Jin arched his hand to Lin Hongfei to apologize, "Mr. Lin, I'm really embarrassed, I am determined to be this villain Lao Jin today." ”

Hearing Team Leader Jin's words, Chen Yaocong nodded secretly: As soon as these words came out, no matter whether he Lin Hongfei really had a grudge in his heart, these words could be regarded as giving Lin Hongfei an explanation.

"It's all for the country and work, can you understand," Lin Hongfei waved his hand, then turned straight and asked Team Leader Jin, "Team Leader Jin, which car does your scientific expedition team that is going to Antarctica value for scientific expedition?" How many do you need? How much do you know about the car's performance? ”

"Just the DT-30PM with the largest load," Jin Leader said, "We have done some understanding of this car, the basic data and performance are still known, the maximum load can reach 30 tons, four rubber tracks, each track width of 1.1 meters, the width of the two tracks accounts for two-thirds of the body width, enough to meet the requirements of snow driving, and the DT-30 that 16.1 meters of body length and 4 meters of trench width, The height of the vertical trench is 1.5 meters enough to ensure the safety of driving in Antarctica. ”

"We have also analyzed, if it is only used in the snow, DT-30PM in the case of a full load of 30 tons of materials, and then use a sled to tow 40 to 50 tons of materials is no problem, the terrain in the Antarctic region is basically not much undulating, there is no need for this car to float, there is no swamp, mud pond such as need to maintain enough buoyancy and reserve power to emergency places, if necessary, pull a few more sleds is no problem, a DT-30PM can carry nearly 100 tons of materials, there are such two vehicles, Coupled with the original three PB240s of the Snow Dragon, we can carry at least 300 tons of supplies, so that the comrades at the Great Wall Station and Zhongshan Station can live much more comfortably. ”

The full load weight of military heavy off-road vehicles is very different from the full load mass that we understand, what do they define, the full load weight is the off-road ability under the condition of keeping the off-road performance of the vehicle unchanged, if you do not consider the off-road performance, the load capacity is simply easy and pleasant, such as the military all-wheel drive truck with a load of 5 tons equipped by our army, which is set in the case of considering the use of the battlefield, but if it is driving on the paved road, pull 20 tons like running fast.

DT-30OM crawler articulated all-terrain amphibious transport vehicle is also, its so-called load of 30 tons, is to ensure off-road performance and amphibious performance under the premise of 30 tons of load, if it is driving in the Antarctic region, in addition to the 30 tons of materials carried by the body itself, it is possible to use a sled to tow at least forty or fifty tons of additional materials, which is equivalent to a time can carry nearly 100 tons of materials and equipment.
