The invention provides a hydraulic lifting machine. The hydraulic lifting machine comprises a stand column and a sliding table, wherein the stand column comprises a longitudinal beam and a top plate arranged at the upper end of the longitudinal beam, the sliding table can be movably arranged on the longitudinal beam in the vertical direction, and a through hole for allowing the sliding table to penetrate out is formed in the top plate; the longitudinal beam comprises a first side wall, a second side wall and a third side wall, the second side wall and a third side wall are arranged on the front side and the rear side of the side wall respectively, a groove is formed among the first side wall, the second side wall and the third side wall, and the top plate seals the groove at the top of thelongitudinal beam; the sliding table is arranged in the groove, a rack is arranged on the stand column, and a safety strip corresponding to the rack is arranged on the sliding table. By means of themechanism, the sliding table can penetrate out of the through hole of the top plate in upward moving process, thus, the highest limit position of the sliding table is no longer limited by the top plate of the stand column, meanwhile, the height of the stand column is not increased, and therefore the overall strength of the stand column is not affected.

    本发明提供一种液压举升机,包括:立柱,立柱包括纵梁和设置在所述纵梁上端的顶板;滑台,所述滑台能沿竖直方向移动地设置在所述纵梁上;其中,所述顶板上开设有供所述滑台穿出的贯通孔。所述纵梁包括第一侧壁、分别设置在所述侧壁前后两侧的第二侧壁和第三侧壁,所述第一侧壁、第二侧壁和所述第三侧壁之间形成一凹槽,所述顶板在所述纵梁的顶部对该凹槽进行封闭。所述滑台设置在所述凹槽内。所述立柱上设置有齿条,所述滑台上设置有与所述齿条对应的保险条。借由上述机构,滑台在向上移动的过程中,可以从顶板的贯通孔穿出。由此,滑台的最高极限位置不再被立柱的顶板而限制。同时,立柱的高度也没有增加,因此也不会对立柱的整体强度造成影响。
