With the longing for high profits, I was already happily imagining the journey. As soon as I stepped onto the pier of Ta Island, I saw Keith walking towards me with a strong anxiety - almost trotting all the way to greet him. He also
Before he could stand still, he shouted loudly and regardless of etiquette: "Little manager, you are finally back!"
"It's broken. Could it be that something happened?"
Seeing his gloomy face, Bolu's happy mood suddenly disappeared. He quickly took two steps and asked: "What happened? Is anyone injured?"
Case, who was about to say something, was suddenly stunned when he heard these words.
"Isn't it because the steel ladle exploded?" Polu was a little anxious: "Speak! What happened!"
Only then did Case react. He waved his hand quickly: "No, the factory is fine and no one was injured. I'm worried about other things."
He turned around and pointed to the gently rising slope not far behind the shipyard: "I have surveyed it many times. From here to the top of the slope, no matter which route we choose, the slope will definitely exceed the thousand thousand you require.
Twenty-twenty points.
At first I thought I had made a mistake, but after repeated inspections several times, I still couldn't get it down to less than 20 parts per thousand."
"It's not that the factory exploded, that's okay, that's okay."
Bolu breathed a sigh of relief, thought about it, but felt powerless again.
At least it wasn't a production safety problem that he strictly guarded and used what can be called a stick education method to prevent. Although it is not as impactful as the ladle explosion, the seriousness of this news is even more terrifying than the previous one.
"It's just a technical problem, and we can still find a way to solve it."
He said to Leonardo, who was returning with him, "It's okay. I'll go work on the production first."
Take the pick-up truck that was placed on the dock when you left and drive for about 10 minutes along the compacted road until you reach the only place you must pass from the dock to the island - an 11-kilometer long
gentle slope.
There is a road on the gentle slope that bypasses the undulating terrain and goes straight to the top of the slope, which was rolled under the heavy wheels of the tractor. For horse-drawn carriages and tractor-trailers, there is no problem in driving back and forth along the existing winding road.
, even quite relaxed.
So Polu always believed that if the slope was flat, there should be no problem at least using a tractor to pull a mine cart on the track to climb up. But it turns out that visual inspection is unreliable, and the illusion caused by the gentle slope is too serious.
.
"The trains that will run on this railway line in the future, whether they are trains carrying products from the factory area or trains from the distribution center behind the dock, which is still a wasteland, will definitely not be empty."
"A heavy-duty train going downhill will not be able to stop if the gradient is too steep, and it will overturn, and may even rush into the sea. A heavy-duty train going uphill will not be able to climb if the gradient is too steep. If it slips, it will still be either.
Rushing into the sea, or overturning. How to deal with such a steep slope? It’s a bit difficult to walk around the big bend from the loading station and go straight uphill.”
Case hesitated for a moment, then put forward his idea: "I went to the other side of the island to see it. The slope will be smaller from that side by going around half of the island, but there are all trees there."
Polu thought about the undisturbed, thick and tall wood that was more than enough to make the pillars of the three main halls, and shook his head:
"Those big trees to the east? It's a pity that this direction can only be used as an alternative. Those trees in the forest, tsk tsk, it's not easy to cut a road. You also have to find a way to dig out the stumps. It's really difficult."
Forget it, let’s think of a way to keep this direction unchanged and solve the slope problem.”
Although he has not done any actual experiments, Polu himself is not very confident. With his current half-baked steam locomotive that was modified from a tractor - mainly the transmission and braking are very primitive, this steam locomotive can,
It’s good to remember the principles of the power part, but who can remember the drawings?
If you hook up a heavy-duty ore train that can easily start at 100 tons, you will definitely not be able to climb this long slope!
"You can't really just drag one or two, right? If that doesn't work, I'll just drive the car forward and backward, and follow the Qinglong Bridge example of taking a zigzag route on this steep slope."
Polu, who has long known that trains are a science that can make people lose all their hair, began to prepare for the rail transportation experiment from the day the iron ore was mined. There is no shortage of wood on the island, and stones are everywhere. As long as there are rails,
Is there any reason not to use rail mine cars for long-distance transportation?
However, various problems discovered during this process have persisted until now, and there is still no good solution - or in other words, there are not good enough products. The heavy-duty mine car that started from the mine started to slip and was extremely difficult. It was not easy to climb up.
When it was time to stop at the mining station, I couldn't stop and overshot.
If the front of the car brakes too hard, the mine car behind me will hit myself under the inertia of the heavy ore loaded and turn myself into a crushed can.
At the same time, it also exposed a problem that is basically impossible to solve by patting the head: track steering.
Although track steering is performed by wheelsets stuck in the rails, the difference in circular diameter between the first and last pairs of wheelsets in a long carriage is a very fatal problem. The middle wheelset passes through a fatally complex device on the track.
to adapt to carriage movement.
This thing is called a bogie.
The high-tech bogie breakthrough can reach the level of news network. So it is not easy to remember the principle of this thing. As for the technical details? They don’t exist. Who can remember this thing if you don’t touch it every day?
So at present, we can only rely on reducing the difficulty to create a makeshift thing - shortening the length of the carriage and straightening the route as much as possible to reduce steering problems. Although this thing treats the symptoms but not the root cause, at least it can still be used on the current experimental track.
.
It's a straight road to Heilongjiang, from the dock to the factory unloading station, and then use the gap between the wheels and rails to make a super big circle and turn back. Or you can hook up the front and rear locomotives and go back and forth in a single line - it's still a straight road to Heilongjiang.
Polu, who stood on the top of the slope, thought about it for a long time and gave up all the technical solutions that were beyond his power.
"Keith, don't look at it. The ramp won't collapse on its own. Let's get in the car first and tell me the data."
Polu, who got into the car, took the data written by Keith in his notebook, lowered his head and calculated silently for a long time, then estimated the distance he still needed to travel, and started the pickup truck. The two drove in silence for a while, Polu
Lu suddenly controlled the vehicle and stopped on the side of the road.
He turned around and looked at Keith with a firm look:
"Keith, the slope from here to the seaside should be almost the same, right?"
"It should be about the same, wait!"
Keith's eyes widened. He hurriedly looked back at the top of the slope that had disappeared behind him, and hesitantly opened his mouth: "Here, here?"
"That's right, I decided to make this place the end point of the railway climb."
