The invention discloses a boarding ladder assembly and a boarding device. The boarding ladder assembly comprises a first ladder frame, a ladder frame connecting piece, a second ladder frame, a ladderframe base, a plurality of pedals, a first connecting rod, a second connecting rod and a connecting rod connecting piece. In the process that the boarding ladder assembly is switched from the folded state to the inclined state, the second ladder frame is kept horizontal with the ladder frame base firstly, the first connecting rod takes a hinge shaft of the third hinge position as a rotating shaft,and the connecting rod connecting piece takes a hinge shaft of the fourth hinge position as a rotating shaft. The connecting rod connecting piece rotates to a horizontal state towards one side far away from the ladder frame base; the first connecting rod and the second connecting rod are kept on the same straight line, and then the first ladder frame and the second ladder frame integrally rotateto the ladder frame base to form a certain angle. Therefore, the purposes that the device is foldable, small in occupied space, adjustable in pedal and convenient to ride are achieved.
