In view of the lack of protection for the descending operation of the fork frame under unexpected conditions in the functional design of the existing "sitting posture state sensing system" of electric forklift,based on the analysis of the principle and characteristics of each action of the electric forklift truck,the particularity that the forklift truck does not need to start the oil pump is summarized,and a solenoid valve combined with relay zero control is designed to be installed in the return oil line of the multi-channel reversing valve.Compared with the redesign of multi-way directional valve structure,the design scheme can realize the effective control of production cost and is easy to implement.
