The invention discloses a stair-climbing crane, comprising a caterpillar base plate, a crane body, supporting legs, a slewing mechanism, a rotary table, a crane arm, a hoister and a suspension head, wherein the crane body is fixed on the caterpillar base plate, the four supporting legs are of a spider-like supporting leg structure and are respectively installed at four corners of the crane body, the slewing mechanism is mounted on the crane body, the crane arm is arranged on the rotary table and is driven by an amplitude-variable oil cylinder to realize lifting of the arm body, and a hoisting rope of the hoister is arranged along the crane arm and hangs the suspension head on the top of the crane arm. The stair-climbing crane employs a straight-arm telescopic crane arm structure, has low deadweight, a small size and good passing capacity and is applicable to driving in passageways; the stair-climbing crane adopts hydraulic driving and the climbing gradient of the crane reaches 35 to 40%; and under the condition of usage of special climbing pedals, the climbing gradient of the crane can reach 45%, so the stair-climbing crane can realize stair-climbing and walking functions and meets requirements for lifting in a building.
