The invention provides a variable amplitude synchronous control system, method and device and a crane, and relates to the technical field of mechanical control. The variable-amplitude synchronous control system comprises a first measuring device which is used for measuring the rope end position offset in each group in at least one group of hoisting mechanisms on the crane; the second measuring equipment is used for measuring the reel rotation amount of each hoisting mechanism in the at least one group of hoisting mechanisms; the controller is configured to determine the rope outlet amount of each hoisting mechanism according to the winding drum rotation amount of each hoisting mechanism; and according to the rope end position offset in each group of the at least one group of hoisting mechanisms and the rope outlet amount of each hoisting mechanism, carrying out variable amplitude synchronous control on the at least one group of hoisting mechanisms. By means of the system, the accuracy and reliability of crane variable amplitude synchronous control can be improved.
