A lifting column, preferably for height-adjustable tables comprises a guide with three mutually telescopic members (1,2,3) and a motor driven spindle unit for bringing about the movement. The second member (2) of the guide is with a lower end secured to a lower end of the second spindle (6). The second spindle nut (8) co-operating with the second spindle (6) is with a bearing (18) with a rigid connection (28) fixed to a shaft stub (16) secured to an upper end of a drive tube (9). The shaft stub (16) is via a second bearing (20) secured to a mounting plate (23), by means of which the spindle unit is secured in the lifting column. Thus, the vertical load on the lifting column is led through the spindle unit around the guide (1,2,3). This enables a better and more optimum dimensioning of the guide (1,2,3) and the spindle unit, just as it is advantageous in terms of assembly and not least it enables a better implementing of a squeeze protection in the lifting columns.
