Abstract
The invention relates to a lifting device (), in particular a semitrailer support or the like, comprising a shank tube () and a support tube () which is movable with respect to the shank tube, wherein on the shank tube, a lifting gear mechanism () is arranged which comprises an input shaft arrangement () for connecting a drive device and an output shaft arrangement () for driving a lifting spindle () which is arranged within the support tube and which rests with one end on a pressure plate () arranged within the shank tube and interacts with the moving end with a spindle nut () arranged in the support tube, wherein the spindle nut comprises a locking collar () with at least two locking devices () which interact with locking latches () formed on the tube wall of the support tube in such a manner that, with a coaxial alignment of the spindle nut with the support tube, the spindle nut can be inserted, in an assembly rotational angle position, into the support tube, and can be moved by rotating about a longitudinal axis () of the support tube into a locking position, in which the locking devices get into engagement with the locking latches.
