The invention discloses an antiskid single-person operated herringbone ladder, which comprises two ladder frames which are hinged to each other at one end. Each ladder frame is composed of two parallel vertically-arranged side plates and multiple pedals which are horizontally connected between the two side plates. The antiskid single-person operated herringbone ladder is characterized in that top successive three pedals of the ladder frame are all provided with an arched shoe lug respectively; and lower end faces of the side plates of the two ladder frames are all provided with bearing suckers with their adsorption planes facing the ground. In comparison with the prior art, the antiskid single-person operated herringbone ladder of the invention has the following beneficial effect: by means of the shoe lugs arranged on the pedals and the bearing suckers mounted on the bottom of the side plates, a single person can control the ladder to move on the ladder; and the antiskid single-person operated herringbone ladder is antiskid, safe, convenient and efficient.
