The passing of the model comparison test undoubtedly proves the feasibility of the "Beautiful Legs" ladder.
With this support, the design of the "Beautiful Legs" telescopic ladder was born, and a finished product with a higher degree of completion was designed. With the support of Li Fanyu's ideas, all that's left is to solve the height and operability issues.
The Zhengxin R&D team is still very capable in this aspect.
But since we want to create a universal platform for heavy-duty fire trucks, just a ladder-like upper is not enough. Maintaining a high platform and raising the jet arm are also top priorities.
Fundamentally speaking, the structures of these two products are very similar. Unlike the straight up and down ladders, the middle and upper parts of the climbing platform and the reporting spray arm need to be connected with angled corners to achieve multi-angle adjustment to meet the needs of fire extinguishing at different angles.
The ascending platform is mainly composed of a straight arm and a curved arm. It is used to transport people and rescue materials to high places, rescue trapped people and spray fire extinguishing agents. It is a comprehensive and multi-purpose fire-fighting upper-mounted machine.
In contrast, although the elevated spray vehicle is also composed of a straight arm and a curved arm, its purpose is quite single - it can only spray fire extinguishing agent to fire floors from high places.
The structure and principle of these two tops are the same, but they have different uses and sizes.
So why not integrate these two products together?
Because of body shape,
The elevated platform is the largest on heavy fire trucks, while the elevated spray arm is the smallest. The reason for this distinction is mainly due to usage.
To sum up in one sentence, the role of the high platform is more to transport people and materials, so it requires a relatively strong and balanced body.
However, raising the spray arm requires flexible and rapid response capabilities to meet the purpose of spraying fire extinguishing agents from multiple angles. The body is relatively smaller and more flexible.
Differences arise depending on the use.
Although they are both long, one needs to be thicker, stronger and more durable, while the other needs to be faster, lighter and more flexible, which creates a contradiction.
But for Li Fanyu, this conflict is really easy to resolve.
Because with his current design level and Zhengshin’s technical level, it is not difficult to combine these two guys!
After completing the aerial 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 elevated platform and spray arm combinations.
The working height is also required, so you can use a raised platform to achieve the height, and combine the spray arm at the front of the raised platform to achieve precise spraying!
It’s like a two-headed snake, with one stick and two heads. Isn’t it easy to make one? The lifting body is shared and the injection system is shared. The only thing that needs to be solved is that two sets of control systems and a hydraulic system are needed to control the platform and the spray arm respectively.
As for whether combining the two will cause a reduction in strength...
With X super aluminum alloy, Li Fanyu is not vain at all!
After a lot of imagination, Li Fanyu designed the combination of high platform and jet arm code-named "Double-Headed Snake". The lower part was designed into the structure of a "beautiful leg" ladder, and a lift was added above. High arm, the front section integrates the conveying platform and spray arm. They share a water supply boosting system, but are controlled by two control systems.
In order to ensure the stability and strength of the "Double-headed Snake" for high-altitude operations, an appropriate amount of relatively strong X2 aluminum alloy is used in key parts of this highly integrated fire jacket, such as the folding joint and the arm joint. .
After the entire top was designed and computer simulated, it was completely feasible!
At this point, in addition to Xu Fufang’s control system, the design direction of the heavy fire truck universal platform and three types of tops has been finalized!
When faced with seemingly difficult things, people always exaggerate the difficulty. If you really put in absolute determination and courage, you will find that things are not as complicated and bad as you thought.
It only took Li Fanyu twelve days to complete all this work!
It took another four days, relying on the abnormal endurance of Constitution +15, Li Fanyu worked tirelessly to help Xu Fufang lay the foundation for the high-precision hydraulic control system.
At this point, all parts of the "Atlas" project have been finalized, and the rest will be left to time and the hard work of engineers to slowly overcome!
At this time, twenty days have passed since the April 2 fire.
The news that Zhengxin has once again accepted a government order and developed a heavy-duty firefighting ladder truck has spread. As an emerging automobile manufacturer, being able to obtain such an order will have a huge repercussions in society.
It is said that the lack of happiness stems from uneven income. This sentence is very suitable for the reaction of the industry when Zhengxin undertakes the heavy fire ladder truck.
It’s okay if people have me, but it’s okay if people don’t have me. But if I have someone or not, a conflict arises. Especially, when what “people” originally owned is snatched into “me” hands.
Who is the least happy about the R&D project that Zhengxin has undertaken to build an ideal fire ladder truck? It is Manson Clay Fire Equipment Company.
With decades of accumulation in the field of fire protection equipment, this German company has produced various fire truck products that have been widely praised and praised by the German domestic market and the international market.
Around the world, the heavy-duty fire truck products produced by this company also have a high coverage. Twenty-five percent of the heavy-duty fire trucks currently used in Europe are produced by Manson Clay. This company also has a 16% share of airport fire trucks in the United States.
As for which country in the world has Manson Clay's business growth the fastest, there is no doubt that it is China.
As China's urbanization process accelerates, urban fire situations become more complex, and the demand for heavy-duty fire truck products is huge. However, the domestic industrial development in this field is lagging behind, giving Manson Clay a very large space for development.
In just ten years from 2007 to 2017, Manson Clay's heavy-duty fire truck series using Mercedes-Benz chassis sold more than 100,000 units in a large region of China.
Among them, fire truck ladder trucks ranging in size from 24 to 65 meters account for 5/3 of the more than 100,000 units.
At present, about 60% of the fire ladder trucks used by fire departments in China are produced by Manson Clay.
It can be said that it has seized the decade when China's urbanization process has developed most rapidly. It can be said that Manson Clay took advantage of the opportunity and became the leader in China's heavy fire truck market in one fell swoop.
Now that Zhengxin suddenly appears and wants to steal their business, can they feel comfortable?
What kind of company is Zhengxin?
Local companies!
Compared to foreign companies like Manson Clay, it has considerable advantages in terms of location and people. The time is right, the place is right, the people are right, and righteous faith accounts for both. How can they not feel a sense of crisis?
Just two days after Li Fanyu completed the main part of the "Atlas" project, Manson Clay's "inspection team" composed of senior managers came to China.
However, this team called the inspection team did not visit the market or Manson Clay's Chinese branch after arriving in China. Instead, they went directly to Tiancheng.
After getting off the plane, we went directly to Zhengxin Group!
