Abstract

A hydraulic leveling base comprises a bracket which can be used in a combination and connection manner or independently and a leveling foot mounted below the bracket. Above the bracket is a supporting surface for bearing. A hydraulic medium is provided inside the leveling foot and can flow inside the leveling foot and/or between the leveling feet to achieve the leveling. In the present disclosure, the leveling foot is provided below the bracket of the hydraulic leveling base, the hydraulic medium flows inside the leveling foot and/or between the leveling feet, and so the amount of compression of the leveling foot under bigger pressure is large, the leveling foot under smaller pressure can extends by the action of the liquid pressure, and then automatic height leveling can be achieved.
