Lifting device for lifting and lowering vehicles, loads or similar having a support which is movable up and down, or support comprising a load receiving means which are movable up and down, wherein the load receiving means has at least one support arm, characterised - in that a jointed connection is formed between the support or the support arm and a mounting part, in the case of which a positive locking of the mounting part with respect to the support or support arm is formed to maintain the angular position after the alignment of the mounting part with respect to the support or support arm in an angular position with respect to each other and a subsequent positioning of a respective longitudinal axis of at least one bore on the support or support arm with a longitudinal axis of at least one bore on the mounting part, and the support or the support arm and the mounting part are fixed with respect to each other by a cotter pin which is insertable into the bores (78, 81), or - in that a jointed connection is formed between the support or the support arm and a mounting part, in the case of which, after a positioning of a respective longitudinal axis of at least one bore of the support or of the support arm and of a longitudinal axis of at least one bore with respect to the mounting part with respect to each other, these are mounted rotatably with respect to each other by inserting a cotter pin and the mounting part and the support or the support arm are traversable relative to each other along this longitudinal axis (79, 82), wherein the mounting part is freely pivotable with respect to the support or the support arm in an adjustment position and a positive locking is formed in a working position after an axial traversing movement between the mounting part and the support or support arm, due to which the adjusted angular positon of the mounting part is fixed with respect to the support or support arm. - in that a jointed connection is formed between the support or the support arm and a mounting part, in the case of which a positive locking of the mounting part with respect to the support or support arm is formed to maintain the angular position after the alignment of the mounting part with respect to the support or support arm in an angular position with respect to each other and a subsequent positioning of a respective longitudinal axis of at least one bore on the support or support arm with a longitudinal axis of at least one bore on the mounting part, and the support or the support arm and the mounting part are fixed with respect to each other by a cotter pin which is insertable into the bores (78, 81), or - in that a jointed connection is formed between the support or the support arm and a mounting part, in the case of which, after a positioning of a respective longitudinal axis of at least one bore of the support or of the support arm and of a longitudinal axis of at least one bore with respect to the mounting part with respect to each other, these are mounted rotatably with respect to each other by inserting a cotter pin and the mounting part and the support or the support arm are traversable relative to each other along this longitudinal axis (79, 82), wherein the mounting part is freely pivotable with respect to the support or the support arm in an adjustment position and a positive locking is formed in a working position after an axial traversing movement between the mounting part and the support or support arm, due to which the adjusted angular positon of the mounting part is fixed with respect to the support or support arm.
