The invention discloses a fulcrum drift method which aims to solve the problems that certain equipment of which the working gravity centers can be changed randomly during an operation and needs to be kept balanced and certain specific facilities need to be kept balanced when foundations supported by the facilities are stressed by outer force. The fulcrum drift method provided by the invention is used for adapting to the continuously random change of the gravity center to form a random balance. (With reference to the accompanying drawings.) An arc-shaped arrayed fulcrum group is arranged at the supporting part of a supported object; when the object generates gravity center drift under the outer force, fulcrums on the object drift simultaneously to obtain a new balance. The method disclosed by the invention is simple and easy to implement and is suitable for automatically providing drift of the fulcrums for the equipment of which the working gravity centers are randomly changed and the certain facilities which are possibly unbalanced as the supported objects or the basic parts are stressed by the outer force.
