Description

technical field [0001] The invention relates to the technical field of engineering vehicle automatic control, in particular to an omnidirectional static pressure forklift control system. Background technique [0002] Forklifts are one of the most important industrial transport vehicles, often used in storage and transportation, which greatly improves the storage and transportation capacity and saves manpower and costs. Forklifts include internal combustion forklifts, electric forklifts and static pressure forklifts. Internal combustion forklifts have two working speeds under full load and no load, and the speed adjustment is inflexible; electric forklifts use gear transmission with simple structure and high transmission efficiency, but they can only complete step speed regulation, and the transmission stability is poor. The static pressure forklift has the advantages of light weight / compact structure, stable operation, etc., and can meet harsh working conditions such as fre...
