The construction equipment is better, at least there are no restrictions on maintenance, as long as you buy the right accessories, you can repair it yourself.

But the maintenance of those vehicles is not so casual in the real world, especially the replacement of large parts such as engines and frames, the requirements are very strict.

When the relevant policies were introduced, perhaps in order to protect the legitimate rights and interests of the parties, the real owners of those stolen vehicles can be found through the number of the engine and frame.

But in reality, the idea is beautiful, but the implementation is difficult.

Because with the support of the existing machining capacity, the engine and frame numbers can also be polished and re-engraved.

However, the majority of law enforcement officers do not have the ability to identify this fraudulent means, so the policy of replacing the main components of the vehicle to be reported has basically lost its meaning and original intention, and has become a shackle for car owners to freely repair their vehicles, and even become a means for some departments to obtain benefits.

Therefore, in this case, some vehicles that could have been restored to normal use after replacing the relevant parts had to be scrapped in order to avoid possible troubles in the future.

In the real world, these vehicles are equivalent to the end of their lives, but in the Huaxia Kingdom of the other world, those disassembled vehicles are reborn in another way through the replacement of the same parts, and once again gain the ability to drive normally.

Perhaps, the maintenance ability of these junior workers in Huaxia is not comparable to that of those professionals in the real world, and the repaired vehicles cannot be restored to the requirements of their design standards.

However, under the existing infrastructure conditions of this Huaxia country, there is no need for such a high standard, and the safe driving speed of 60 or 70 kilometers can already crush the world's best means of transportation.

After Huaxia gradually cultivates enough machining personnel, it can confidently and boldly start the comprehensive mechanization process.

Because in the absence of machining capacity, more investment in machinery and facilities can only increase the burden of Wei Minsheng as a porter in the two worlds.

For those scrapped vehicles with serious rust due to the appearance, Huaxia does not have the ability to refurbish at present, but in fact, the power system of these scrapped vehicles can basically continue to be used.

Like some classic cars abroad, under the careful maintenance of the owner, they have gone through decades of wind and rain, and can still meet their daily needs.

In order to give these power systems a good place, Wei Minsheng bought some seamless steel pipes with a diameter of about 50cm from the real world, as well as some plates.

After cutting these steel pipes into ten-meter sections, the two ends of the steel pipes are welded and sealed with steel plates to form an enclosed space that acts as a unit for the water trap.

These seamless steel tubes, which are sealed at both ends, can provide nearly two tons of buoyancy each after removing their own weight.

The sealed steel pipes were tested with the help of a tower crane on the dock to ensure that there was no water ingress and then fixed side by side with angle steel to form a platform.

The four sides of the platform are welded with steel plates with a bevel to reduce the resistance of the platform when moving through the water.

This ten-meter-by-ten-meter surface transport platform can reach a total carrying capacity of nearly forty tons.

In order to prevent the goods from being affected by the river during transportation, a cargo hold was made of wooden planks and fixed on the platform.

In the middle of one side of the transport platform welded by steel pipes, a power platform is welded with the cut car girders.

Under the water surface around the power platform, a triangular anti-collision protection frame was also made with sealed steel pipes to enclose the power platform.

Then the power system of the separated car is fixed on the power platform, and a small house is made of wood as an operating room, while avoiding the engine and related circuit system from being wet by rain.

The powertrain is connected to the gearbox and then works with the throttle to easily accelerate, decelerate and steer, and a propeller with 360-degree steering can be used to flexibly control the direction of travel of the transport platform through the gears.

Such a simple transportation platform is simple to make, and the size is also very suitable for the wharf built before, and the loading and unloading of goods can be solved by the tower crane or conveyor belt on the wharf, which greatly saves manpower.

On top of that, the platform has a shallow draft and excellent passage performance for a waterway that has not yet been hydrographically surveyed and cleared.

The cylindrical structure of the steel pipe has excellent collision resistance, and it is not easy to be damaged by the general underwater rock.

The independent buoyancy unit will not suddenly lose buoyancy of the entire platform even if there is an accident, and there is enough buffer time for rescue work in unexpected situations.

In addition, the welding and assembly of all components of this platform can be completed by Huaxiaguo's current technical strength, and there are almost no technical obstacles to maintenance.

Even if they haven't mastered the overhaul technology of the car's powertrain, they have enough scrapped cars to provide the overall replacement capacity of the powertrain.

The power system that has been replaced can allow them to practice to their heart's content, and familiarize themselves with the role of various engine accessories through continuous disassembly and assembly.

At the same time, with the help of relevant books, we will gradually accumulate experience in various engine maintenance and make technical reserves for the future large-scale mechanization process.
