The invention provides a crawling crane gravity center control system and a control method thereof. The system comprises a crawling crane, two track shoes and four pressure monitoring units, wherein a supporting surface of the crawling crane is constituted by a rectangle formed by the peripheries of the two track shoes, a movable balance weight of the crawling crane is placed on a balance weight slide of a main machine, and is connected with the main machine by a balance weight telescopic oil cylinder, the pressure monitoring units are symmetrically distributed at four corners of the two track shoes of the crawling crane and are close to end parts, when the crawling crane lifts a weight or performs amplitude variation action, the gravity center of the whole crane would change, and the change can be offset by pushing or pulling a balance weight structure close in real time by using the balance weight telescopic oil cylinder according to pressure signal changes detected by the pressure monitoring units at the four corners, so that the gravity center of the whole crawling crane is always in the center of a quadrangle. The crawling crane gravity center control system and the control method can improve the safety and reliability of the whole crawling crane, play a roll of preventing rollover and greatly enhance the safety and reliability of the whole crawling crane.
