A thrust lifting device that is able to transmit a thrust force for lifting loads, includes at least one articulated lift column provided with at least one meshing part, and with at least one arm directed upward from the meshing part, the lift column made up of links with a link of rank 1 at the upper end of the upwardly directed arm and running links of rank n, where n is between 2 and N, the number of links of the lift column, —at least one rotary pinion driving the lift column by the meshing part meshing with the pinion, —at least one arm opposite the upwardly directed arm and formed by resting links, the resting links being able to pass to the meshing part and to the upwardly directed arm by rotation of the pinion, and —at least one stabilizer that is movable along the upwardly directed arm.
