The development history of carrier has experienced three generations of development, and the development of carrier is moving to the fourth generation. The first generation of carrier is a manual carrier, CBY for short, which is characterized by low automation and intelligence, but it has made a great contribution to the transformation from manual handling to mechanized handling. Today, it still has a certain market share in the carrier market; The second generation carrier is an internal combustion carrier represented by an internal combustion forklift, referred to as FT, which has high automation. The internal combustion forklift is powered by an engine and has strong power. The disadvantage is that it has exhaust emissions that pollute the environment, has low efficiency, is harmful to human health, and is not suitable for use in the food industry; The third generation carrier is an all electric carrier represented by an electric forklift, called CBD for short. Its degree of automation is similar to that of an internal combustion forklift, but it is a power technology update driven by the concept of energy conservation and environmental protection. It uses battery power. The electric carrier has the advantages of energy conservation, no exhaust emissions, low noise, etc., and is the best choice for the food industry. Because of its outstanding advantages of energy conservation, It is considered by the truck industry as one of the most potential forklift trucks in the future, but it has encountered a development bottleneck. Due to the limitation of battery capacity, it has low power and short operation time. The development of the fourth generation carrier is represented by automatic unmanned carrier, which is called AGVS for short, AGVS is expected to be widely used in the 1950s. It is an effective means of logistics transportation in today's flexible manufacturing system (FMS) and automated storage system. Modern AGVs are controlled by computers. Most AGVS are equipped with centralized control and management computers to optimize the operation process of AGVs and issue handling instructions, Tracking the components in transmission and controlling the route of AGV, the guiding methods of the unmanned carrier mainly include electromagnetic induction guidance, laser guidance and magnetic gyroscope guidance. It can program the unmanned carrier to input and guide the carrier to complete the handling work. It is a highly intelligent carrier.
The carrier, also called pallet truck, is mainly divided into manual carriers: Bangshiqi manual hydraulic carrier, high lift scissor carrier, electronic scale carrier, manual pallet carrier and other semi electric carriers: semi electric carrier, semi electric pallet carrier and other all electric carriers are being loaded: all electric carrier, all electric pallet carrier, Explosion proof manual hydraulic carriers such as electric pallet carriers: explosion-proof bulls, explosion-proof pallet carriers
