Provided is a control method for a balance weight of a tire crane with a movable balance weight system. According to the method, a gravity sensor and a tilt angle sensor are detected, a tilt angle and a sling load are converted to moment, a movable balance weight device is started, and the rotation angle of the movable balance weight device is detected for feedback. By means of the steps, balance control over a movable balance weight of the tire crane is achieved. Alternatively, spiral landing legs are arranged at the four corners of a crane body, pressure sensors used for detecting pressure exerted on the spiral landing legs are arranged on the spiral landing legs, the difference values between the pressure sensors are compared, the movable balance weight device is started, and the rotation angle of the movable balance weight device is detected for feedback, and by means of the steps, balance control over the movable balance weight of the tire crane is achieved. According to the control method for the balance weight of the tire crane with the movable balance weight system, by the adoption of the steps, automatic control over the movable balance weight can be achieved, the movable balance weight can be matched with the moment of the sling load, moment balance is achieved, construction safety is ensured, and the service life of equipment is prolonged.
