The invention discloses a lifting platform base for high-altitude work. The lifting platform base comprises a fixed base, wherein the fixed base comprises a working platform on which support rods are connected crosswise; a hydraulic push rod is arranged on the crossed support rods; a movable roller box is arranged on each of four corners of the fixed base; each movable roller box is internally provided with a roller jacked by a cam; a movable support block is correspondingly arranged on each of four corners of the fixed base; the working platform is provided with a mobile moving platform; a rotating platform is also arranged on the moving platform. The lifting platform base disclosed by the invention can be applicable to demands of different lifting platforms; the base is stable and can sufficiently contact the ground by contracting rollers at the bottom of a traditional hydraulic lifting platform; in addition, the movable support blocks can be extended from four corners to increase the attachment area on the ground and further play a supporting role.
