The invention discloses a method monitoring fatigue service life of a crane beam; the method comprises the following steps: recording position information of the crane beam; setting position information of fatigue checking computation points for the crane beam; setting up a corresponding stress amplitude function for each the fatigue checking computation point of the crane beam, wherein the stress amplitude function uses hoisting weight and walking position as input variables; using the corresponding stress amplitude function to calculate a stress amplitude formed on the fatigue checking computation point by a hoisting object in each walking process of the crane beam; converting the stress amplitude of the fatigue checking computation point of the crane beam into a stress amplitude cycle index indicating fatigue life. The method can monitor the fatigue service life of the crane beam without needing a stress induction sheet, so monitoring cost and construction difficulty cannot be obviously improved by increasing number of the crane beams and fatigue checking computation points.
