Claim 7:
8. A thrust lifting device, adapted to transmit a thrust force allowing for lifting of loads, comprising:
at least one articulated lift column provided with at least one meshing part, and with at least one arm directed upward from the at least one meshing part, the at least one lift column being 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, with n comprised between 2 and N, wherein N is the number of links of the at least one lift column,
at least one rotary pinion driving the at least one lift column by said at least one meshing part meshing with the at least one pinion,
at least one second arm opposite the at least one upwardly directed arm and formed by resting links, said resting links being able to pass to the at least one meshing part and to the at least one upwardly directed arm by rotation of the at least one pinion, and
at least one movable stabilizer that is movable along the at least one upwardly directed arm, wherein each of said at least one movable stabilizer comprises one ring per each of said at least one articulated lift column and a frame rigidly connected to the ring, said ring comprising a sliding member with respect to the corresponding lift column and a stabilizer finger for driving the at least one movable stabilizer in motion, the stabilizer finger configured to bear against the corresponding lift column when the tappet encounters the stabilizer finger, by an upper surface thereof, the stabilizer finger displaceable with respect to the sliding member with dampening of said displacement by a damper.
