The invention relates to a fixed hydraulic lifting machine which comprises a base, a bearing platform, supporting arms and a driving mechanism, wherein the supporting arms are positioned on two sides of the base and are arranged in an internal-external crossed manner; the driving mechanism is used for driving the supporting arms to being relatively unfolded or folded; each supporting arm comprises a first supporting arm and a second supporting arm; the first supporting arms and the second supporting arms are arranged in an internal-external crossed manner and rotationally connected with each other; the lower end parts of the first supporting arms are rotationally arranged on the base; the upper end parts of the first supporting arms are arranged at the bottom of the bearing platform in a sliding manner; the lower end parts of the second supporting arms are arranged on the base in a sliding manner; the upper end parts of the second supporting arms are rotationally arranged at the bottom of the bearing platform; the hydraulic lifting machine also comprises first supporting rods and second supporting rods; the first supporting rods are used for connecting the lower end parts of the second supporting arms on two sides synchronously; the second supporting rods are used for connecting the middle upper parts of the supporting arms on two sides synchronously; the driving mechanism comprises hydraulic cylinders and a hydraulic pump station; two end parts of the hydraulic cylinder are respectively and rotationally arranged on the first supporting rods and the second supporting rods; and the hydraulic pump station is arranged on the base, and is positioned between the supporting arms on two sides. The fixed hydraulic lifting machine can realize the lifting of the bearing platform relatively stably.
