Abstract

A cargo handling control device with cargo handling device elevated by oil hydraulic driving mechanism on the elevator of loading cargo, and cargo handling control device which controls the operation of above elevator through controlling the flow control valve's opening/closing degree of the oil hydraulic driving mechanism, includes: 1. offset detecting device for detecting the offset between the current position and the target stop position of the above elevator or the part linked to the elevator; 2. fuzzy control device for controlling the flow control valve's opening/closing degree according to the increment/decrement value which is base on the current opening/closing of flow control valve, the output offset from the offset detecting device and inference from the fuzzy control rules by skilled operator.
