As a result, how can electric forklifts operate safer turns out to be a main problem of the society? The focal point lies in the stability of central control system when the electric forklifts works. The chief problem which the electric forklifts producers face is how to improve the stability of central control system. The control microprocessor adopts the newest (DSP)TMS320LF2407 chip, then a central control system of electric forklifts is designed based on DSP technology. The author analyses the main factors affecting vertical and lateral stability of electric forklifts trucks. According to the kinematics, mechanics and geometry, the critical state when electric forklifts work is derived, then by the way of binding software and hardware to control and guarantee the stability of electric forklifts. Firstly, the essay introduces the study value and content from the development purpose and trend of electric forklifts; Secondly, according to the working condition and requirements of the electric forklifts, the author analyses the factors affecting the stability and concludes control requirements of different components of the electric forklifts hardly, the author designs software and hardware in accordance with the requirements of operation, communications, differential and stability to satisfy security and stability.
