The invention provides a hydraulic system for variable amplitude control of a suspension arm and a control method. The hydraulic system comprises a first variable-amplitude ascending oil way, a first variable-amplitude descending oil way, a second variable-amplitude ascending oil way and a second variable-amplitude descending oil way; the first variable-amplitude communicating oil way is connected with the first variable-amplitude ascending oil way and the first variable-amplitude descending oil way; the second variable-amplitude communicating oil way is connected with the second variable-amplitude ascending oil way and the second variable-amplitude descending oil way; the flow of hydraulic oil in the first variable-amplitude ascending oil way is consistent with that of hydraulic oil in the second variable-amplitude ascending oil way; the flow of hydraulic oil in the first variable-amplitude descending oil way is consistent with that of hydraulic oil in the second variable-amplitude descending oil way; the flow of hydraulic oil passing through the first variable-amplitude balance valve and the second variable-amplitude balance valve is consistent; the first variable-amplitude hydraulic motor and the second variable-amplitude hydraulic motor can rotate synchronously; the variable-amplitude winch can stably act; and meanwhile, the risk of pressure unbalance of the hydraulic system is reduced.
