Its working principle is very simple. It is installed on the top of a skyscraper like a hat, and a large number of construction workers and engineering equipment will be deployed on the building machine. Only raw materials such as cement need to be continuously sent to the platform, and the engineering team can directly build the building inside the building machine. Because of the fully enclosed design, workers are on the ground when working in the building machine, even if they suffer from a strong wind of magnitude 8, there will be no danger, and the safety is guaranteed. Because of the concentration of a large number of workers and engineering equipment, the speed of building skyscrapers with building machines is also very fast, and China even set a new world record of four days and one floor.

　　The building machine itself is fixed on the skyscraper by hydraulic equipment. After a new floor is built, workers will use jacks and hydraulic equipment to lift the building machine and all the equipment it carries up one floor, and then they can build a new floor until the building is capped. How will such huge equipment be dismantled after the building is capped? China's solution is also very clever. After the building is capped, workers will first dismantle the engineering equipment that can be dismantled, and then take them to the building first, leaving only the building builder itself and several heavy tower cranes on the roof.

　　The aerial building machine and its supporting construction technology are large-scale combined mechanical equipment platforms with intelligent control. They are cast-in-place assembly construction technologies with excellent quality, controllable cycle, economical cost and environmental protection.

　　"Aerial Building Machine" is a large-scale mechanical equipment composed of 13 standard devices according to the shape of the building, with high standardization of components and strong general interchangeability. Its principle is: its work simulates a "mobile building factory", and the instructions such as lifting and formwork automatic opening and closing are completed by mechanical operation and program control at the construction site, thus realizing the industrial construction of cast-in-place reinforced concrete.
