heavy duty machine moving skate role as the main force in logistics handling, its operations can not be ignored. Mobile logistics activities, physical space, vertical movement called Stacker (stacking) logistics, transportation logistics parallel movement called, these two logistics activities are the most common logistics activities, logistics, as well as handling logistics, these logistics processes are inseparable from the participation of heavy duty machine moving skate. Value of heavy duty machine moving skate is increasingly prominent, heavy duty machine moving skate main function is to complete the transport logistics activities. 

heavy duty machine moving skate history, has experienced three generations of development, heavy duty machine moving skate developments are the fourth generation of development. The first generation of heavy duty machine moving skate for manual heavy duty machine moving skate, referred CBY, which is characterized by automation, intelligence is not high, but it is for the manual handling of mechanized handling the conversion to make a great contribution, to date, it is the heavy duty machine moving skate market still have a certain market share; second-generation heavy duty machine moving skate is represented by the internal combustion internal combustion forklifts heavy duty machine moving skate, referred to FT, with high automation, internal combustion engine forklift for power, powerful, there is a drawback emissions pollute the environment, the effectiveness of lower harmful to human health, is not suitable for the food industry to use; third-generation heavy duty machine moving skate is fully electric electric forklift as the representative of heavy duty machine moving skate , referred to as the CBD, the degree of automation and internal combustion forklifts pretty, but it is the driving force to promote the concept of energy saving technology updates, using a battery-powered, electric heavy duty machine moving skate with energy, no emissions, noise etc, food the best choice for the industry, because of its energy-saving advantages, are heavy duty machine moving skate industry, considered one of the most promising future forklift, but encountered a bottleneck in the development, due to its limit by the capacity of the battery, power is small, the job short time. The fourth generation of heavy duty machine moving skate development is automatic unmanned heavy duty machine moving skate represented, referred AGVS, AGVS in the 1950s is expected to get a wide range of applications, is the flexible manufacturing system (FMS) and automation warehousing system effective means of transport and logistics, modern AGV is controlled by the computer, most of AGVS with centralized control and management of computer systems, used to optimize the operation process of the AGV, issue handling instructions, tracking and controlling transmission components AGV route, no heavy duty machine moving skate boot methods are mainly guided electromagnetic induction, laser guidance and magnet gyroscope guidance, etc., can give no heavy duty machine moving skate programmed input to guide heavy duty machine moving skate complete removal work , is an intelligent relatively high heavy duty machine moving skate.
