Zhengxin's R&D team has been divided into four parts: the R&D team of F750 with OEM as the main body, the R&D team of the general platform for heavy-duty fire trucks led by Liu Qing, the ladder, lifting platform and lifting jet arm project team led by Wang Yu, and the R&D team of hydraulic remote control/control system led by Xu Fufang.

After the project was launched, the entire R&D center was busy. In desperation, Li Fanyu had no choice but to invite Professor Zhang, who was not in good health for a while ago and had been recuperating at home for more than two months, to be responsible for the coordination and deployment of the four teams.

The old man is actually in good health, but his three proud disciples can stand alone at this time, and his original disciple who is not a weapon has also become a business giant that stirs up the Chinese automobile industry.

As a teacher, Lao Zhang is already satisfied to see this achievement in the year of the sixtieth year. So after his health was better, he didn't rush to work, but took leave from the group and led Li Fanyu's sister to Qiongya for a vacation.

After Li Fanyu called and explained the current situation of the R&D center, the old man flew back without saying a word.

With Lao Zhang in charge of the central coordination, Li Fanyu's burden was lighter. But the workload is still overwhelming.

Because the R&D project is too huge, Li Fanyu personally served as the chief engineer of the "Atlas" project.

The R&D tasks of the four parts are not simple, not to mention that the fire platform and fire tops are fields that Zhengxin has never set foot in, and many things need to be handled by him personally.

In order to save time, while waiting for the OEM engineer team to come to China, he had already partially completed the drawings of the F750. So after the arrival of little Kurbo and others, he began research and development work with him. In order to ensure that he could get out quickly, Li Fanyu spent three days and three nights explaining the important points of the F750.

The OEM branch has been responsible for the specific work of the F150 since it was classified as Zhengxin. As the first and only model produced by Zhengxin in the North American market, the OEM's engineering team's understanding of this model is simply deeply imprinted in the bones.

The F750 is similar to the F150 in terms of structure, making it easy for engineers to master. If it weren't for this, Li Fanyu would not be able to get rid of it in a short period of time.

After explaining all the key points and letting the OEM engineers understand it, Li Fanyu, who got rid of it from this side, started the design of the general platform with Liu Qing's team.

In fact, it is not difficult to develop a separate bodyload platform that can carry the ladder, lift the jet arm and ascend the platform. It is nothing more than to do a good job in weight distribution, and make a reasonable layout of the materials used in the overbody part of the axle, so that it can support the weight and working state of the bodywork machinery.

But who made Li Fanyu's request special?

The difficulty in the design and development of Zhengxin's heavy-duty fire truck general platform lies in how to perfectly integrate these three heavy-duty fire truck bodywork!

If it is specialized, then the design engineers can completely combine the platform with the bodywork, and start from the foundation to carry out a little climbing design.

But for the purpose of "generic", it would be too complicated.

What do you say about this feeling?

It's like cracking a combination lock.

The special fire platform is like a three-digit password lock; from 0 to 9 ten digits, using a stupid method, that is, 000 to 999 to enter the password one by one, it is nothing more than 10x10x10, that is, a thousand password combinations. If you're lucky, for example, if you come across a password like 099, you may only need to find it 99 times to succeed.

However, if you want to achieve the purpose of "universal", it is undoubtedly equivalent to adding another English to this combination lock, and it has become a four-digit mixed combination lock.

THE COMPLEXITY LEVEL HAS CHANGED FROM 10X10X10 TO 62X62X62X62! The original 1,000 combinations have also been increased to 10 million.

Li Fanyu is also very helpless, the goal he set is indeed too big,

But looking at the market, what is not difficult is often accompanied by an outrageously low price. If you can't understand this, it doesn't matter, just look at the Yiwu small commodity market.

But things with high technology content are often accompanied by great value and added value.

Take a very ordinary thing as an example: the same is a lighter, the kind of disposable advertising lighter given by the restaurant during the meal, the price is only one dollar. However, the zippo that is windproof and coldproof and can be forced can often be sold for two or three hundred in an ordinary model.

That's the gap.

For the sake of huge profits and huge market competitiveness, it should be a necessary quality for every technology-based enterprise to fight against difficulties.

Obviously, Zhengxin and Li Fanyu have.

Moreover, Li Fanyu has not only the courage to break the kettle - he also has design expertise.

After researching a large number of foreign heavy fire truck top-mounted platforms, he found inspiration in the SAU-54654 Russian-made fire ladder designed in this time and space but not in service.

In fact, the platform of SAU-54654 fire ladder truck is not advanced, and this fire truck is an airport light fire ladder truck for airport rescue.

But in order to meet the airport fire rescue mission to the greatest extent, this ladder truck uses a retractable work platform that looks crappy. Obviously, this is a failed design for the SAU-54654 fire truck, and it has been widely criticized by the airport fire department.

But where and when. Li Fanyu saw this telescopic design, but it was like a treasure.

The principle of telescopic is certainly the most in line with the scheme he envisioned.

After a heated discussion with Liu Qing and others, which was almost quarrelsome, the design direction was decided.

In order to meet the different heights of ladders, as well as two different categories of bodywork, climbing platform and lifting jet arm. Inspired by the SAU-54654 airport fire truck bodywork platform, Li Fanyu proposed the modular multi-purpose platform concept of telescopic slide rails combined with turntables.

Normal heavy-duty fire truck bodywork is fixed on the axle to obtain a firmer mechanical bottom, a simpler control system structure and the most suitable mechanical support points. However, the inevitable result of such a design is that the chassis can only be equipped with one top.

As urban buildings become more complex, so do the environments in which fires occur. In many cases, a special car is required.

The problem is that ladders and climbing platforms are rarely used in urban fires.

The purpose of the climbing platform is to transport personnel to high altitudes, rescue materials, rescue trapped people and spray fire extinguishing agents.

The purpose of the ladder is exactly the same as this, and it can be said that the performance and function of the two heavy-duty fire lift trucks overlap to a large extent.

If a fire department has a ladder, it will not use the climbing platform to a large extent.

So with the ladder, is it possible to avoid climbing the platform?

No!

The complexity of the location of the fire determines the necessity of any kind of firefighting equipment. The ladder is vertically retractable and cannot be turned from the middle part. Therefore, in the case of some situations where it is necessary to enter the firefighters by an angle, or to use a special angle to guide the spraying of fire extinguishing agent, it is necessary to use a climbing platform that can adjust the telescopic angle or orientation.

It may not be needed, but it must be. This is a very contradictory problem in the field of equipment required for modern firefighting operations.

And this modular general platform designed by Li Fanyu exists to solve such a problem!

According to the design concept of telescopic slide rail combined with turntable, if the design is feasible, then this platform can be used to carry ladders of different heights, climbing platforms of different heights and lifting jet arms of different heights! It only takes a very short time to complete the switching of three kinds of bodywork on a heavy-duty fire truck chassis.

In this way, you can achieve the purpose of multi-purpose car!

What does this mean?

It means that after the fire occurs, the firefighters can freely choose which tops to load according to the specific situation from the front! It means that they only need to be equipped with firefighting tops, and they do not need to be equipped with towing vehicles! It means that the procurement cost and maintenance cost are greatly reduced! It means that it can save a lot of money for the fire department!

It means that if this modular fire platform comes out, it will set off a bloody storm in the field of heavy-duty lifting fire truck chassis!
