Zusammenfassung:	The embodiment of the invention provides a method and system for eliminating the stroke error of a lifting oil cylinder, and relates to the technical field of oil cylinders. The method for eliminating the stroke errors of the lifting oil cylinders comprises the steps that a synchronous hydraulic cylinder is additionally arranged between a first lifting oil cylinder and a second lifting oil cylinder; the hydraulic valve is opened, liquid enters the liquid inlet cavity of the synchronous hydraulic cylinder to push the two pistons to move synchronously, and therefore the first lifting oil cylinder and the second lifting oil cylinder move synchronously. A synchronous hydraulic cylinder is arranged between the first lifting oil cylinder and the second lifting oil cylinder, and liquid synchronously enters the first lifting oil cylinder and the second lifting oil cylinder through the synchronous hydraulic cylinder, so that it is guaranteed that the oil inlet positions of the first lifting oil cylinder and the second
