    I. Classification of aerial work vehicles:
    1. Divided by type: vertical lift type (also known as shear fork type) aerial work vehicle, folding arm type aerial work vehicle, self-propelled aerial work platform, telescopic boom type aerial work vehicle. Among them, the vertical lifting work bucket has a large bearing capacity, but the operating height is limited, the maneuverability is poor, and it is not flexible. At present, the folding arm lifting aerial work truck is widely used in China.

    2. According to operating height: 6 meters, 10 meters, 14 meters, 16 meters, 18 meters, 22 meters, 25 meters, 30 meters, 50 meters, currently the highest foreign countries can reach more than 80 meters.

    Second, the scope of application of aerial work vehicles:

    Widely used in electric power, street lights, municipal, gardens, communications, airports, shipbuilding (repair), transportation, advertising, photography and other high-altitude operations.

    Third, the characteristics of aerial work vehicles:

    There are operating devices in the bucket and the slewing seat, which control the start, stop, high speed and low speed of the engine from a long distance. The electro-hydraulic proportional valve is used to control the movement of the arm. Rotating, the level of the working tank is automatically maintained by the link mechanism. When the main pump fails, the emergency pump can be operated to lower the working tank. It has night lighting and can lift heavy objects.

    Fourth, the future development of aerial work vehicles:

    People have conceived a combined aerial work vehicle that can make a car more versatile. This car has a front part (mainly equipped with a power system), which can be used independently or connected with different boxes to become a minivan, tourism Cars, refrigerated cars, racing cars, etc. can be replaced at any time as needed. In the future world of cars, there will be several special passenger systems for cars. One is the "air bus" vehicle, which has the advantages of land and air. It can be used on land as well as ordinary buses. Fly into a special plane for air travel, reducing the hassle of getting on and off passengers.

    In the future, there will be more aerial vehicles with strange shapes and excellent performance. For example, crawler-type air-cushion vehicles can replace the wheels of a car with inflatable rubber crawlers and can walk freely on muddy roads or swamps. Wheelless walking car is modeled after the characteristics of animals walking. It is equipped with four legs, and it is very flexible under the potholes and mud. There are also water, land and air vehicles, UFO cars, submarine cars, and so on. Computers are widely used in aerial work vehicles, which will be an important symbol of future cars. Future cars will be equipped with computer command systems. The driver's will and external driving conditions can be combined into electrical signals, which are then transmitted to the microprocessor. After analysis and calculation, instructions are issued to various parts of the vehicle. Make cars safer and more reliable. There can even be driverless "smart" cars. There is also a self-driving self-propelled passenger car. The size of the aerial work vehicle is similar to the current passenger car, with four or six seats. The difference is that this passenger car has only two wheels and one on the left. The cantilever is connected to the upper left track of the vehicle. In addition to the guide, the track is also responsible for transmitting automatic signals and transmitting power.
