A balance adjustment method for a lifting platform, the lifting platform comprising a controller, an inclination sensor and at least two groups of lifting mechanisms arranged at two opposite sides of the lifting platform, and the inclination sensor and the lifting mechanisms are in signal connection with the controller, wherein, it comprises the following steps: S1, detecting with the controller whether an inclination adjustment signal is received or not, if the inclination adjustment signal is not detected, continuing to detect, and if the inclination adjustment signal is detected, skipping to next step; S2, detecting with the controller whether the lifting mechanisms are still, if detecting that the lifting mechanisms are in operation, returning to S1 to continue detecting, and if detecting that the lifting mechanisms are still, skipping to next step; S3, detecting with the inclination sensor the inclination of the lifting platform and sending the detected inclination to the controller, comparing the detected inclination with a set inclination threshold by the controller, if the detected inclination exceeds a set threshold A1, skipping to next step; if the detected inclination is less than or equal to the set threshold A1, skipping to S1 to continue detecting; S4, controlling with the controller ascending or descending of the lifting mechanism at a first side while continuing to detect with the inclination sensor, and if the detected inclination is less than that detected in S3, skipping to next step; if the detected inclination is more than or equal to that detected in S3, controlling the lifting mechanism at the first side to move in a reverse direction, and then skipping to next step; and S5, continuing to detect the inclination with the inclination sensor, and when the detected inclination is less than or equal to the set threshold A1, controlling all lifting mechanisms to stop operation. S1, detecting with the controller whether an inclination adjustment signal is received or not, if the inclination adjustment signal is not detected, continuing to detect, and if the inclination adjustment signal is detected, skipping to next step; S2, detecting with the controller whether the lifting mechanisms are still, if detecting that the lifting mechanisms are in operation, returning to S1 to continue detecting, and if detecting that the lifting mechanisms are still, skipping to next step; S3, detecting with the inclination sensor the inclination of the lifting platform and sending the detected inclination to the controller, comparing the detected inclination with a set inclination threshold by the controller, if the detected inclination exceeds a set threshold A1, skipping to next step; if the detected inclination is less than or equal to the set threshold A1, skipping to S1 to continue detecting; S4, controlling with the controller ascending or descending of the lifting mechanism at a first side while continuing to detect with the inclination sensor, and if the detected inclination is less than that detected in S3, skipping to next step; if the detected inclination is more than or equal to that detected in S3, controlling the lifting mechanism at the first side to move in a reverse direction, and then skipping to next step; and S5, continuing to detect the inclination with the inclination sensor, and when the detected inclination is less than or equal to the set threshold A1, controlling all lifting mechanisms to stop operation.
