Trucks have experienced four generations of development. The first generation is manual, characterized by low degree of automation and self-supply. However, it has made great contributions to manual handling to mechanized handling. Today, the first generation products still occupy a certain market share in the market. The second generation is the internal combustion handling equipment represented by internal combustion forklift, which has a high degree of automation. The engine power of forklift truck is strong, but the exhaust gas discharged into the environment pollutes the environment, has low efficiency and is harmful to human health, so it is not suitable for food industry. The third generation truck is an all-electric handling equipment represented by electric forklift. Its automation level is equivalent to the second generation. It uses battery power supply, which is more energy-saving, no waste gas emission and low noise. It is the best choice for the food industry. But its disadvantages are limited battery capacity, low power and short working time.
Nowadays, the fourth generation trucks are widely used. This kind of handling equipment is represented by automatic unmanned handling. It is an effective means of logistics and transportation in today's flexible manufacturing system FMS and automatic storage system. It is controlled by computer and equipped with centralized control and management computer, which is used to optimize the treatment process, issue correct treatment instructions, track the components in transportation and control the treatment route. The guiding modes of unmanned handling mainly include electromagnetic induction, laser guidance and magnetic gyro guidance. The unmanned handling equipment can be programmed and input, and then guided to complete handling. The fourth generation is already a highly intelligent handling equipment.
There are also special operations explosion-proof trucks. This kind of explosion-proof loading and unloading equipment mainly includes battery explosion-proof forklift and battery explosion-proof loading and unloading vehicle, which comprehensively handles the factors that can cause explosion, such as sparks, static electricity and temperature. Its motor and electrical appliances are flameproof, and its power supply device is also a special flameproof type. It can be used in dangerous places where explosive gas mixtures exist, such as petroleum, chemical industry, textile, pharmacy, food and national defense. Used for loading, unloading, handling and stacking of goods. Van's quotation varies greatly according to the manufacturer's brand, so the price of retail van in the market also fluctuates greatly.
Although the performance and working efficiency of trucks have been greatly improved, the four generations of handling equipment still occupy a certain share in the market.
