The invention discloses a lifting device and a lifter. The lifting device adopts a guide suspension box and a bracket which are matched; a limiting slot in the guide suspension box has two upward height limiting positions and a lifting position along a motion track; the limiting slot of the guide suspension box is utilized to limit the motion track of the bracket, so that the bracket is blocked while upwards travelling to the first height limiting position, and is dropped to the lifting position while falling back, thereby realizing bracket locking; when the bracket upwards travels again, the bracket is blocked while upwards travelling to the second height limiting position, and then is released while falling back. The lifting device is simple in integral structure; in a process of completing lifting locking and release dropping, the bracket is only required to apply with upward force, and therefore, the implementation and the operation are easy.
