To be exact, they should be called platforms with eight wheels, two meters wide and six meters long. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 The info wheels are made of steel with grooves in the middle, so you can no longer walk on open ground, and you have to cooperate with the steel rails that hit the ground.

Soon on either side of the first building, two long steel rails were assembled, and the platform was pried onto the rails, the brakes were released, and it only took a few people to easily propel the walk.

In the end, the four platform trucks were fixed into a square, and between the two on the same side, a set of steel frames more than ten meters long were connected together. Steel frames were erected diagonally on top of the platform, which were finally joined together at a height of 10 meters to form a stable triangle.

The final work is to connect the triangular shelves on both sides again with two rows of steel frames of sufficient span, install rails on top of the steel frames, and finally put two small mobile platforms with a small diesel engine, transmission, brakes and complex accessories such as wire rope drums.

Three days later, the world's first "gantry crane" was built, and in the former world of Renault, it was nicknamed the floor crane.

It can easily lift several tons of steel in the up-and-down direction, but in order to maintain synchronization and stability, the movement of the front and rear and left and right directions is still driven by a relatively primitive hand-cranked gearbox.

Although the speed is slower, the good thing is that the longest of a house is more than 30 meters, and a crane is operated by seven people, and the efficiency is many times faster than shoulder-to-shoulder. As long as the tractor pulls all kinds of steel underneath it and hangs it on a huge iron hoist, a steel plate weighing several tons can quickly rise from the ground, like a Hercules.

After the crane was installed, after simple commissioning and training, several young laborers were officially inducted. Six people are responsible for the direction of operation, and one person is in command.

In the shrill whistle, the two oil extractors on top of the beam rumbled at the same time, black smoke rose straight up, and a steel plate four meters square and eight centimeters thick was slowly lifted off the ground.

Crunch――

The weight of up to ten tons made the beam sink down leisurely, and the joints made a heart-numbing sound.

Standing at a distance, Renault observed the camber of the beam with a strange instrument, and said, "No problem, go on." ”

The crane is designed to lift 20 tons, and the structure of the beams is in the machine shop, which has been repeatedly tested by blacksmith Ferrier, and the possibility of problems is really small.

Soon two identical steel plates were placed in the building position and laid flat on top of each other.

This is a steel plate used as a "foundation", and the purpose is to prevent the monsters that can make holes from sneaking up from the ground, so it doesn't need too good materials, and it belongs to the most inferior product in Black Iron Town.

It's just that it's in high demand, and all now half of the blast furnaces are producing this steel plate.

And the anti-corrosion of this road is very important, before the laying, someone brushed a large amount of resin and rubber on it, and then it was deeply integrated by Weiwei.

As for the splicing between the iron plates, it is no longer necessary for Wei Wei to take action in person. Charlotte used Vivi's demonic power to create thousands of "welding guns".

One of the advantages of this tool made with the power of demons is that the operator does not need any skills, he only needs to press the switch, aim the black mist sprayed from the "welding gun" at the place that needs to be connected, and then slowly move along the gap.

The only thing to note is that this kind of welding torch is not only steel, but everything can be connected together, so the person in charge of welding is drawn from the guard, and the welding torch must be returned to the warehouse for unified storage after the end of work every day.

After the floor of the first house was laid, soon the upper sewers were also laid, with the assistance of a crane, and then the frame of the house, encapsulating the floor and wall panels.

Renault specially asked people from Sequoia Town to find those who had participated in the construction of Black Iron Town before. Under their leadership and command, this kind of two-story small building was not a problem at all, and it only took three days for one house to be preliminarily completed.

Later, you only need to install doors and windows, kitchen and toilet pipes in the room, and brush them with antiseptic materials.

Of course, there are follow-up insulation layers and thermal insulation layers, residential areas and street greening, etc., which need to wait until a district is completed or all completed, and then unified implementation and configuration.

From the lifting of the first steel plate to the initial completion, it took only seven days.

Xavier and Yoruba have been shocked countless times in the past few days, and if they hadn't witnessed the whole process with their own eyes, they wouldn't have believed it.

From blasting loose earth to building houses, how many of these things are things they haven't seen before, haven't heard of, or even can't understand?

An army of 100,000 is terrifying, capable of destroying a city overnight.

But I'm afraid that no one in the entire Oro Continent or even the entire world dares to guarantee that a hundred thousand troops will be able to build such a city within a year.

Except for Renault.

Yes, it was all brought by Renault.

Looking at the figure who was commanding the assembly of the second gantry crane in the drizzle, Xavier and Yoruba once again admired him from the bottom of their hearts.

There are a total of 33 such gantry cranes, which are side by side and start at the same time from west to east. This means that every week, 33 houses will be built.

Within seven days, someone had already connected the track on the ground to the next building location, so that the construction could continue without delay.

Excluding breaks and equipment failures, one hundred and thirty houses are guaranteed to be completed every month.

The construction of the entire city will be completed in the next eight months, a month ahead of Renault's projection.

Of course, in the proximity to the city center, the structure of the house is a little more complicated, and there are many aspects to consider such as shops, hotels, various public buildings, public transportation, etc. After all, Hammer City in the future will be a giant city with a population of more than 100,000 or more.

Therefore, when Renault designed the city, the streets were particularly spacious, with a gap of nearly 50 meters between each house, and the open space between the community and the community was 200 meters, spacious enough to race horses on it.

This was done for the sake of the future, Renault did not think of this world where land is not charged, and the people who lived in Hammer City had to squeeze around the tight streets, and the whole city did not see a trace of greenery.

These vacant lots can be used as green belts in the early stage, and can be easily transformed into public facilities such as parking lots and wet markets.

Renault wants to build Hammer City into a real garden city, and then make it possible for every household to drive a car, preferably one per person, with parking everywhere, and no charge. (To be continued.) )
