The invention provides a tower crane double-trolley double-amplitude synchronous control mode, and belongs to the technical field of tower crane control. The problem of synchronous adjustment of double luffing of the trolley is solved, and the problem of accumulated errors caused by suspension of a traditional steel wire rope is eliminated; according to the technical scheme, the device comprises a main controller, the main controller comprises a signal input module, a signal processing module and a signal output module, the signal input module is externally connected with multiple sets of travel switches and speed sensors, the signal output module is externally connected with multiple motor driving controllers, and the output ends of the motor driving controllers are connected with motors; a signal input module of the main controller judges according to feedback signals of the multiple sets of travel switches and the speed sensor through a signal processing module, and then a signal output module controls the running speed of a corresponding motor through a motor driving controller according to the judgment of the signal processing module. The method has the beneficial effects that speed and position double-closed-loop control is adopted, and it is effectively guaranteed that the positions of the two trolleys are synchronous, accurate and efficient.
