The passage of the model comparison test undoubtedly proves the feasibility of the "beautiful legs" ladder. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

With this as a support, what is born is to spread the design of the "beautiful legs" telescopic ladder and design a finished product with a higher degree of completion. With the support of Li Fanyu's thinking, the rest is to solve the work of height and operability.

Zhengxin's R&D team is still very strong in this aspect.

However, since it is a common platform for heavy-duty fire trucks, it is not enough to just install a tops like a ladder. Raising the platform and lifting the jet arm is also a top priority.

Fundamentally, there is a great similarity in the structure of the two goods. Different from the straight up and straight down of the ladder, the middle and upper parts of the climbing platform and the reporting spray arm need to be connected with folded angles to achieve multi-angle adjustment to meet the needs of fire extinguishing at different angles.

The ascending platform is mainly composed of a combination of straight arm and curved arm, which is used to transport personnel to high places, rescue materials, rescue trapped people and spray fire extinguishing agents, which is a comprehensive multi-purpose firefighting bodywork machinery.

In contrast, although the high-lift jet is also composed of a combination of straight and curved arms, its purpose is quite simple - it can only spray fire extinguishing agent to the fire floor from a high place.

The structure and principle of these two tops are the same, but the purpose is different and the size is different.

So why not integrate these two goods together?

Because of the size,

The lifting platform is the largest of the heavy fire truck bodywork, while the lifting jet arm is the smallest. The reason for this distinction is mainly because of the use.

To sum up in a word, the role of the high platform is more to pick up and drop off personnel and materials, so it needs to be relatively strong and strong.

However, lifting the spray arm is to meet the usefulness of multi-angle fire extinguishing agent spraying with flexible and rapid reaction ability. It is smaller and more flexible.

Depending on the application, the gap arises.

Although they are all long sticks, one needs to be thicker, stronger and more durable, and the other needs to be faster, lighter and more flexible, which creates a contradiction.

But for Li Fanyu, this conflict is really easy to solve.

Because with his current level of design and the technical level of Zhengxin, it is not difficult to combine these two guys!

After finishing the ladder, Xu Fufang's precise hydraulic control system has made a breakthrough. In Li Fanyu's view, as long as the control system is accurate and powerful enough, it is effortless to design a set of elevating platform jet arm combinations.

The same working height is required, so it is completely possible to use the high platform to achieve the height, and combine the jet arm at the front end of the lifting platform to achieve precise spraying!

Just like a two-headed snake, the design of two heads with one stick is not easy to do? The lifting body is shared, and the jetting system is shared. The only thing that needs to be solved is that two control systems and hydraulic systems are needed to control the platform and the jet arm respectively.

As for whether the combination of the two will cause a decrease in strength......

There is X super aluminum alloy, Li Fanyu is not false at all!

After some brainstorming, Li Fanyu codenamed "Double-Headed Snake" high platform \ jet arm combination, the lower part of the design into the structure of the "beautiful legs" ladder, a section of lifting arm is added above, and the front section integrates the conveying platform and the jet arm. One water supply booster system is shared, but two control systems are separated.

In order to ensure the stability and strength of the "double-headed snake" in high-altitude work, a relatively strong X2 aluminum alloy is installed on this set of highly integrated firefighting tops, such as key parts such as folding and adapter and arm joints.

After the whole set of tops is designed, after computer simulation, it is completely feasible!

At this point, in addition to the control system on Xu Fufang's side, the design direction of the general platform for heavy-duty fire trucks and the three bodyworks has been finalized!

When faced with something that seems difficult, people will always exaggerate the difficulty too much. If you really put in a lot of determination and courage, you will find that things are not as complicated and bad as you imagined.

After all this work was done, it only took Li Fanyu twelve days!

It took another four days, with the metamorphosis endurance of +15 physique, Li Fanyu worked tirelessly to help Xu Fufang set the tone for the high-precision hydraulic control system.

At this point, all the parts of the "Atlas" project have been finalized, and the rest is left to time and the hard work of the engineers to slowly overcome!

At this time, twenty days have passed since the 4.2 fire broke out.

Zhengxin once again undertook government orders, and the news of the development of heavy-duty fire ladder trucks has spread. As an emerging automobile manufacturer, it can obtain such an order, and the repercussions in the society are quite large.

It is said that the lack of happiness stems from uneven returns, which is very suitable for the reaction of Zhengxin in the industry to undertake the heavy-duty fire ladder truck.

There is no problem with me, and it is more OK to have no me. But I have no people, and there is a contradiction. In particular, in the case of snatching what "people" originally owned into the hands of "me".

If you want to say that Zhengxin undertakes the research and development project of a fire ladder truck, who is the most unhappy, it is Manson Clay Fire Fighting Equipment Company.

With decades of accumulation in the field of fire-fighting equipment, the German company has produced a variety of fire-fighting truck products that have been widely respected and praised by the international German domestic market and the international market.

Worldwide, the company produces heavy fire truck products, which also have a high coverage. Twenty-five percent of the heavy-duty fire trucks currently used in Europe are manufactured by Manson Clay. Airport fire trucks in the United States also have a 16 percent share of this company.

And if you want to say which country has the fastest growth of Manson Clay's business in the world, then there is no doubt that it is China.

With the acceleration of urbanization in China, the situation of urban fires is becoming more and more complex, and the demand for heavy-duty fire truck products is huge. The backward development of this field in China has given Manson Clay a lot of room for development.

In just ten years from 2007 to 2017, Manson Clay's heavy-duty fire truck series with Mercedes-Benz chassis sold more than 100,000 units in a large region of China.

Among them, from 24-65 meters of fire trucks and ladder trucks, accounting for more than 53% of the more than 100,000 units.

At present, about 60 percent of the fire ladder trucks used by fire departments in China are produced by Manson Klein.

It can be said that it is the decade in which China's urbanization process has developed most rapidly. Manson Clay can be said to have taken advantage of the time and became the leader of China's heavy-duty fire truck market in one fell swoop.

Now that they are unexpectedly popping up and want to steal their business, can they feel comfortable?

What kind of company is Zhengxin?

Local companies!

Compared with foreign companies like Manson Clay, it has a considerable advantage in terms of location and people. The time and place are favorable, and the righteous faith accounts for the two, how can they not have a sense of crisis?

Just two days after Li Fanyu completed the main part of the "Atlas" project, Manson Clay's "study tour" composed of senior executives came to China.

However, after arriving in China, the team called the investigation did not visit the market and Manson Clay's Chinese branch, but went directly to Tiancheng.

After getting off the plane, I came directly to Zhengxin Group!
