Represented and described is a lifting device having a housing, a lifting spindle that is cylindrical and has an external thread on the outer surface, a threaded bush that surrounds the lifting spindle and has an internal thread that is in engagement with the external thread and a drive unit for the rotating drive of the threaded bush, wherein the lifting spindle is mounted in the housing so as to be displaceable in its axial direction and non-rotatable. The object to provide a lifting device that has as short an installation length as possible in the axial direction of the lifting spindle is achieved in that the lifting spindle is in the form of a hollow cylinder, in that a dome is located in the interior of the lifting spindle and is connected in a non-rotatable manner to the housing and in that the lifting spindle is mounted on the dome so as to be non-rotatable and axially displaceable.
