description The invention provides a platform crane torquemeter compensation method. The method involves a torquemeter main circuit system and an amplitude-variable lifting pilot control hydraulic system. The torquemeter main circuit system comprises a PLC control circuit and a torquemeter output circuit. When a crane changes amplitude or a lifting hook acts, the PLC control circuit determines whether the crane changes amplitude or the lifting hook acts, and corrects an obtained corresponding first correction value when the lifting hook acts, a corrected actual measurement value is more accurate, after amplitude changing slows down, a second correction value is obtained to obtain an actual measurement value for a lifting load weight measurement value, the first correction value is larger than the second correction value, after amplitude changing slows down, the inertia influence caused by too high rising speed is reduced, and therefore the correction value is correspondingly reduced, and the actual measurement value of a
