"Huh, you're a coward." Liu Dajun said angrily. He originally wanted to motivate Qin Zhenhua to participate in this tank crushing training together. It was enough to pull someone on his back. Who knew that Qin Zhenhua would not pay attention to him at all?
Their contemptuous expressions made him even more unbearable.
Lin Zhu didn't say anything and turned a deaf ear to his provocation.
"Attention everyone, a new batch of crawlers has arrived. Class 1 and Class 2 of Platoon 3, go to Warehouse No. 4 and follow the unloading." Lin Zhu shouted.
Now that the replacement of the new engine has been completed, they put the replaced engine into the warehouse, and then began the intensive renovation.
Now, new parts have arrived. When he heard this order, Liu Dajun frowned. These little shoes have been worn all the time.
Repairing the engine is tiring enough, but unloading the cargo is naturally even more tiring. It's none other than the tracks!
The tank can run on the ground as if it were flat, no matter what the terrain is, because it is walking on its own paved road. This is the track of the tank, which turns complex terrain into a flat road. The track is
A pair of big feet of a tank.
Nowadays, the tanks used in China all use single-pin crawler tracks, that is, one pin passes from left to right. This method has a simple structure, is integrally cast, and has low cost. However, due to the friction area of the track pin during use,
Both the angle of rotation and the angle of rotation are large and wear out quickly. When the wear of the pin lugs becomes larger, the length of the track will increase. Therefore, tank tracks are almost one of the essential parts of daily maintenance for tank soldiers. In different terrains, the tracks must be adjusted differently.
If the tightness of the track is improperly adjusted, it is easy for the track to break.
At the same time, the life of the tracks is not long. Under the current circumstances, although it is not necessary to completely replace the tracks with the tank units, it is already necessary to store a certain number of tracks as backup.
A crawler track weighs close to two tons, which is definitely a laborious job. Even with a crane, it is still very tiring.
Liu Dajun followed the squad leader and walked out. The warehouse was nearby. At this time, the transport track pads had arrived.
The track is made up of sections. In order to facilitate operation, the assembled track is rolled up, just like a toilet paper roll. Of course, this roll is quite high. For a short tank soldier, it is almost
It's almost reaching my shoulders.
The newly cast track pads still have a jet-black metallic luster. Due to the casting, they have a rough texture of coarse gravel. Of course, after being hung on the tank, they will be polished and shiny in a few days.
.
The removed track shoes were placed on the open ground, one roll after another. This time, just looking at this kind of guarantee, I knew that there must be something big, including replacing the engine and various parts.
With constant assignments, Xiao Hei probably had a premonition that something was unusual in the army now.
Their backs were soaked with sweat, and after removing ten rolls of tracks, everyone was exhausted and had no strength left.
Huang Chuanchuan couldn't help but leaned behind a pile of tracks, then took out a cigarette from his pocket and held it in his mouth.
Liu Dajun walked away, trying to find a corner where no one was paying attention to release the water.
Just as Huang Chuanchuan was about to light a cigarette, he felt the track pads behind him shaking, and then, there was a bang in his head.
Damn, you're in trouble!
Originally, the track pads were relatively stable, but as soon as he leaned on them, they became loose, and then, for some reason, the track pads actually started to move!
I didn’t do it myself, it must have been caused by the uneven ground!
Huang Chuanchuan was dumbfounded. He watched the rolls of track shoes move slowly. With fear in his eyes, he took a step back. Whoever this thing hits will be in trouble.
As soon as the track shoes started to move, no one could control it. Then, right in front of his eyes, the track shoes started spinning like a windmill. It started very slowly, very slowly, but as it turned forward, the speed increased.
It’s starting to increase!
This is very similar to a toilet paper roll. When the toilet paper roll falls down, you will find that the toilet paper roll starts to rotate. As it rotates, the paper roll spreads out and rolls out far away.
The rolled up track is also doing this kind of movement now. It starts to rotate. At the same time, when it turns to the bottom track, it starts to become flat. In this process, the center of gravity of the track roll is constantly decreasing, and the gravitational potential energy is increasing.
The reduction is all converted into kinetic energy, so when the track shoes are unfolding, the speed in front becomes faster and faster!
In the maintenance company, we used to do this kind of action. When replacing the tracks of a tank, we spread out the track shoes like this. If calculated correctly, the end of the track shoes can just reach under the road wheels of the tank. Then
Calling a fluency is as fun as toppling dominoes.
But now, it's different. When it's spread out, they still have to roll it up, which is even more strenuous work!
Moreover, when his eyes followed the direction in which the track pads rotated and unfolded, he became even more frightened.
"Army, be careful, be careful!" Huang Chuanchuan shouted loudly.
Liu Dajun, just on the path of the track pads, like a roaring steel dragon, the track pads rolled towards Liu Dajun!
Liu Dajun turned his head, and at that moment, the rolling tracks appeared in his retinas and in his brain.
Suddenly, his legs became weak.
He thought about the tank crushing training again. The tracks should have rolled over like this. The tracks were rolling, just like the tracks on the tank were constantly moving. The track pads were turning and rushing towards him.
, this giant steel dragon is opening its big mouth and biting him down!
Liu Dajun was afraid inside.
Without the training of the past few days, Liu Dajun might have been able to react and avoid the rolling tracks. But now, all Liu Dajun could think about was the tank crushing training, and what would happen if something unexpected happened.
All kinds of unexpected and tragic situations scared him out of his wits. Now, suddenly faced with this situation, Liu Dajun was confused.
There was something in his pants, and he didn't even feel it falling down drop by drop. In his eyes, there was only the rolling tracks, and in his mind was only the image of being crushed, so that he could hear the shouts in his ears.
Not here anymore.
"Army, hide quickly, hide quickly!"
Huang Chuanchuan was really anxious. He saw that the track pads were about to roll over. As it kept spreading out, the speed became faster and faster, and the ground began to shake. If Liu Dajun didn't avoid it, the track pads would roll over.
It will roll Liu Dajun down and crush his entire body. Then, the bones will be broken, the internal organs will be broken, and even the head will be smashed!
