The invention discloses an arch bridge construction cable tower crane frame displacement control system and a using method. The arch bridge construction cable tower crane frame displacement control system comprises a displacement detection device, a tension device and a controller, the displacement detection device is arranged at the top of a tower frame, the tension device is arranged at the ground anchor end of a wind cable, and the controller controls the magnitude of tension applied to the wind cable by the tension device according to tower frame displacement data fed back by the displacement detection device. When the tower frame is displaced, the tension device can apply the tension to the wind cable, therefore it is ensured that the tower frame is in a perpendicular state or a smalldisplacement deflection state, and since the wind cable can be timely tightened according to the displacement of the tower frame, the wind cable with large rigidity and the large diameter is not needed. The arch bridge construction cable tower crane frame displacement control system can achieve active control of the displacement of the tower frame, optimal control can be achieved according to actual displacement conditions of the tower frame, the safety of the tower frame when the stress is high is ensured, the control effect of the system is good, construction materials are saved, and largedisplacement and repeated deformation of an arch rib are avoided.
