Each pulling element is constructed to raise only the one lifting element relative to the standing element. The height-adjustable device has a locking device that locks the pulling elements by a non-positive or positive locking engagement on the corresponding one of the pulling elements. The locking device is constructed to synchronise the movement of the pulling elements.
