The invention discloses a cantilever crane. The cantilever crane comprises a supporting column, a steering motor, a main moment arm, an auxiliary moment arm, a hydraulic jack, a back auxiliary rod, afront auxiliary rod, a grooved wheel, a lifting rod, a motor, a steel wire rope and a lifting hook supporting column; the supporting column is of a cylinder structure welded by steel materials; the steering motor is fixed to the upper surface of the supporting column; the main moment arm is formed by cutting a steel plate and connected to the supporting column through a supporting shaft; the auxiliary moment arm is formed by cutting a steel plate and hinged to the main moment arm through cooperation of the front auxiliary rod and the back auxiliary rod; the lower end of the hydraulic jack is screwed to the tail end of the main moment arm through a screw, and the upper end of the hydraulic jack is screwed to the tail end of the auxiliary moment arm; the grooved wheel is installed at the front end of the main moment arm; the lifting rod is movably hinged to the front end of the auxiliary moment arm through a screw; and the motor, the steel wire rope and a lifting hook form an electric hoist. The cantilever crane has the advantages that the structure is light, and running is stable.
