The invention belongs to the technical field of quay crane operation control, and particularly discloses and provides a quay crane precise heavy-load type electric push cylinder tilting control system which comprises the steps that by recognizing the actual tilting posture of a container on a lifting appliance relative to a target position, the deviation amplitude angle of the tilting posture of the container on the lifting appliance is constructed, and the tilting posture of the container on the lifting appliance is calculated; the tilting posture deviation signal of the electric push cylinder is constructed, the real-time tilting correction of the electric push cylinder is realized, and the fine adjustment function of the heavy-load electric push cylinder of the quay crane in a short-stroke high-frequency moving working state is realized; the tilting operation load type of the electric push cylinder is recognized, the control speed and the control acceleration of the electric push cylinder are adjusted in real time, and the stability of the motor in the tilting process is ensured; and the tilting correction reaction effect index to which each tilting correction record of the electric push cylinder belongs is recognized, the correction operation dead zone range of the electric push cylinder is set to serve as the limiting condition of tilting adjustment of the electric push cylinder, and mechanical abrasion caused by frequent correction of equipment due to tiny deviation is avoided.
