The invention provides a cantilever crane anti-back-tipping device and a crane. The crane comprises a main arm, a tower arm and a supporting rod, wherein the tower arm and the supporting rod are arranged on one side of the top of the main arm in a rotary manner. The cantilever crane anti-back-tipping device comprises an extrusion block, an anti-tipping connecting rod, an oil gas cylinder, an anti-tipping rod and a clamping groove part, wherein the extrusion block is fixedly arranged on one side, far away from the tower arm, of the main arm; one end of the anti-tipping connecting rod is hinged to the main arm, and the other end of the anti-tipping connecting rod is connected with a connecting shaft and can be in contact with the extrusion block; one end of the oil gas cylinder is hinged to the supporting rod, and the other end of the oil gas cylinder is hinged to the connecting shaft; one end of the anti-tipping rod is hinged to the connecting shaft, the other end of the anti-tipping rod is a free end, and the free end is suspended between the tower arm and the supporting rod through an inhaul cable arranged on the supporting rod; and the clamping groove part is formed in the tower arm, and the free end is clamped to the clamping groove part so as to position the tower arm when the tower arm backwards slants. By means of the cantilever crane anti-back-tipping device, the tower arm and the supporting rod can be supported; and the force arm of an application point is larger, and the impact force on the tower arm and the supporting rod can be reduced.
