I am an industrial worker during the War of Resistance

Chapter 63 Mobile Firepower Platform
Chen Changzai picked up a wrench from the workbench next to him.

He tapped on the triangular track plate in front of him.

The single-tooth track steel plate, with its very large length-to-width ratio, responded to Chen Changzai's clanging sound.

This indicates that the steel plate is of very good quality.

"How much does this entire assembly weigh?" Chen Changzai asked.

"This assembly weighs 60 pounds, and we have done our best to reduce its overall weight."

Its track plates are hollow, and so is its drive gear.

Even its load-bearing rollers and tensioner rollers, we have tried our best to reduce their weight.

"Even so, it didn't drop below sixty jin," Chen Changzai's student replied.

As the head of the technical team at the tractor and tricycle manufacturing plant, Xu Hongchang felt that he had truly let his teacher down.

The teacher gave him this blueprint and told him and his technical class that "we should try to reduce the weight of this track assembly as much as possible."

Ideally, the weight should be reduced to below 50 pounds.

But he felt very ashamed that he hadn't even lost 60 pounds.

Chen Changzai looked at this triangular track assembly, which had already been made as lightweight as possible.

He said to Xu Hongchang, "It's alright, it's just that my assumption was wrong, the problem isn't with you."

To give this little guy better grip and a larger bearing area, I designed the tracks to be too wide.

You've done a very good job.

I think the hollow support for your drive wheel is very well designed, much better than what I suggested originally.

And the multi-hole design of this chain plate is a very good idea.

This can both reduce weight and shake out the soil that has squeezed in.

very good.

I completely agree with your ideas.

Moreover, with the assistance of two team members, the 60-pound weight can be easily replaced and repaired.

This track assembly can be customized according to your design.

"Will the vehicle's mounting brackets be able to support their weight?"

"Yes, teacher."

On the box panel hanger, we adopted a shortened side folding box panel.

The front panel and the body are riveted together as a single unit.

This way, the connection won't loosen due to its weight.

These two positions do not hinder the raising and lowering of the four lifting supports.

There were no obstacles when the tires were attached.

With a rack on each side, it can easily meet the need to change clothes at any time in the field.

Our hydraulic jacks can lift this car anywhere.

Even under heavy load, it works without problems.

"Yes, Not Bad.

You can put this little guy on now.

Let's see how it works.

"is teacher."

Xu Hongchang then worked with his classmates who were surrounding him, and quickly installed the triangular track assembly onto the wheel.

After those five thick, heavy bolts tightened the 60-pound triangular track assembly.

Chen Changzai smiled happily.

It has a drive wheel, a tension wheel, and a rocker arm-type independent spring suspension linking the load wheel.

Isn't this just a simplified, scaled-down tank chassis?

"Take it slow, the tanks will come."

Chen Changzai thought to himself.

After the two triangular tracks were attached to the tricycle.

Xu Hongchang and his team used a jack to remove the four wooden blocks underneath the vehicle.

The entire car fell to the ground.

Two triangular tracks steadily supported the vehicle bed.

At this moment, Chen Changzai said, "Hang up those two wheels."

"Good teacher."

The students quickly and skillfully attached the two wheels to the front of the two carriages, on the left and right sides of the racks.

Use three nuts to fit onto the three fixing bolts that protrude from the wheel hub bolt holes.

These three screws securely fastened the wheel to the frame.

According to Chen Changzai's idea.

If this vehicle needs to travel long distances, then tracks alone are not enough.

One is that it is slow.

Another point is that the farther the tracks travel, the higher their failure rate becomes.

Therefore, different wheels and tracks are used depending on the road conditions.

That would be a good way to resolve this contradiction.

After all, it's just a small car.

Those two tracks together weighed only 120 pounds.

The impact on this three-wheeled vehicle was not that significant.

It can still handle it. After all, this can solve many problems.

Compared to other options, it's still a good deal.

With a sputtering sound, the three-wheeled vehicle, now fitted with iron tracks, rattled and clattered its way out of the workshop.

You know what, this speed isn't slow at all.

"Uncle, Political Commissar Liu, what do you think of this guy?"
I wasn't lying to you, was I? I said I could get this heavy machine gun onto this vehicle.

Have you uploaded it now?

"You guys give it a try," Chen Changzai said with a chuckle to Commander Chen and Political Commissar Liu.

Commander Chen and Political Commissar Liu, who had been specially summoned, stared in surprise at the tricycle in front of them, which had been fitted with a new pair of rear wheels.

I'm at a loss for words.

A triangular support has already been installed on this tricycle.

That's a tripod for a 12.7mm heavy machine gun.

Now, whether it's rifles, submachine guns, or this newly developed dual-purpose heavy machine gun, it's all the same.

All the equipment has been sent to the headquarters ordnance factory.

That area is now the main production site for these firearms.

Chen Changzai is here only to provide them with production equipment.

However, they still have some of these heavy machine guns left here, one of which is for use by the air defense forces on this side.

Another thing is that Chen Chang continued to research and improve the prototype guns in the factory.

When Commander Chen saw the heavy machine gun on the vehicle, he noticed that the height-adjustable central support was already at its lowest position.

The seat behind it is the perfect position for operating the machine gun to fire horizontally.

He couldn't help but feel an itch to touch it.

From the rear door, I held onto the railing of the trunk panel.

He got into the car in one step.

He sat down and pulled the bolt.

This position is just right; I can pull the bolt with force.

Upon closer inspection, there was no ammunition box attached to the gun, and no bullets were in the chamber.

Then he released the bolt handle.

Bolt reset.

Commander Chen then placed both feet on the floor of the carriage.

With a push of his left foot, the machine gun muzzle smoothly turned to the left.

With a push of his right foot, the gun barrel turned to the right again.

The gun handle is pressed down and the muzzle is pointed upwards, which is very smooth.

When a gun is being turned, the muzzle must never be pointed at your own people.

This is the rule.

With the muzzle pointing upwards, Commander Chen pushed off with one foot, causing the entire gun, including his chair, to begin to spin.

There was no jamming during the 360-degree rotation.

Smooth but not loose.

This way, the machine gun won't fire bullets haphazardly.

If the gap between the fixed gun mounts is too large, the rotation will be loose or stuck.

That would severely affect shooting.

At this moment, Commander Chen shook the height adjustment wheel again.

When the machine gun position is adjusted to the highest level.

He was sitting in the chair at a semi-reclining angle, a very comfortable position for shooting.

He twisted the gun handle up, down, left, and right with both hands.

Even when the body is still, the shooting angle is not small.

This feeling can only be described with two words: "comfortable".

"Let's drive it and give it a try. Let's drive it to the testing range, fire a couple of shots, and get a feel for it."

Chen Changzai and Political Commissar Liu exchanged a glance and then both laughed.

The three-wheeled vehicle deliberately drove on the uneven road surface, although it was a bit bumpy.

But this meant nothing to Commander Chen.

We haven't even been on the horse yet.

The three-wheeled motorcycle sped off to the firing range.

After firing ten bullets each in both direct fire and anti-aircraft fire, Commander Chen fired ten bullets.

He said to Chen Changzai, "Steady, very steady, the whole gun can stay steady."

The car doesn't shake.

Good stuff, it's a really good thing.

Changzai, this should be given to Uncle first.

With this, there's no need for bunkers or pillboxes.

I drove straight there and took them all.

Hahaha~"

　Thank you to all my friends who have supported me.
