Anonymous users2024-02-15Let's tell the truth, the aviation and aerospace manufacturing industries of various countries can be manufactured, but the cost is too high to enter the civilian field, and it is quite difficult to make this device in the general military industry.
You should start with 500,000 yuan, 50,000 yuan is not a thing.
Those "skilled craftsmen", "social talents", and "experts and professors" are just rubbish.
To buy a 2 million yuan elevator house, you invest 2 million yuan in national research institutes, China's top ten colleges and universities, making such a device is equivalent to throwing it into the water, and it can't even be soaked.
A few years ago, the Ministry of Science and Technology of the People's Republic of China publicly put forward the regulations for project initiation and acceptance, but no one who knows how to do it accepted it.
What's more, China's industrial base is so indiscriminate!
Those senior engineers and special technicians are all fraudsters!
As for structural analysis, dynamic theory, and advanced machining, it is too simple.
Give a suggestion, Canada, Australia, Japan have joint ventures in China, on the production of a variety of electric lifting devices by the stairs, is for this purpose to enter the Chinese market, its structure is the same, but the material is good, the process is reliable, there is a long history of experience, note: not suitable for high-rise buildings!
Is there a wheelchair to go up the stairs?
Western industrialized countries have long had production, generally have a starting price of 100,000 yuan, Chinese buy private jets are a large number of people, buy high-end power-assisted devices no one pays, would rather buy a mansion, self-built indoor elevators.
Its high power density, large unit power-to-weight and volume ratio is not at all something that China can grasp, whether it is hydraulic or electric, the performance of metal materials produced in China is too far apart!
Similar products made in Taiwan are very bulky.
It is able to slowly change from a standing posture to a sitting posture, and then continuously change to a lying down wheelchair, Europe and the United States have long been finalized production, originated in Europe, America and Japan, is a high-end wheelchair, and Taiwan is imitating in China, and Taiwanese goods will be sold for 40,000 yuan, which is introduced on the Internet.
If it is a crawler structure and a starwheel group structure, it is about 10,000 yuan in China, and it is not safe if it is cheaper.
Imported stair-climbing wheelchairs are generally more than 30,000 yuan to ensure safety and reliability.
If the transmission structure is complex, 300,000 yuan is normal.
If you want Hu Jun to open the equipment that has been idle for more than 20 years, I can make it for you on a voluntary basis.
I have enough engineering and technical ability, and the leader doesn't do it, so I can't help, I'm very sorry.

Strongly support the landlord's idea I suggest you give your dad a razor, such as Philips, like our parents' generation, who have not pursued much materially (buy your own things and feel that you have to use them) Last year I bought a Philips razor with my dad (he used to use a razor blade) Although I didn't say it in front of me, but every time I shaved, I would show it in front of my mom, saying, "This son is good, he can buy things, and the shaving thief is clean", my dad is also reluctant to buy good things for himself, so let's buy things for my dad as a child, it must be good, and it belongs to the comparative" leather"Of course, if your dad uses other hobbies, he will give him what he likes, but what about Mom? Women are all beauty lovers I think the landlord will send an eye cream A little less when buying cosmetics Try to buy some anti-aging such as wrinkle removal eye cream (I heard my girlfriend say buy some vitamin e to my mother It has an anti-aging effect The price is not expensive) When buying cosmetics, the landlord must buy brand goods such as Olay Pull Shiseido Pull This is not for my mother This is to send face After your mother uses it, her complexion is good Your mother's circle "Three aunts and six aunts" still don't ask "What's the matter?" What's the card? >>>More
