The invention discloses a traction type arch-bridge crane of a crane carriage. The traction type arch-bridge crane comprises the crane carriage, a crane span structure, a cart travelling mechanism and electrical control equipment, wherein the crane span structure is a four-beam structure which is arched in middle; a crane carriage travelling rail on the crane span structure is laid along an arched main beam upper cover; a trolley travelling mechanism of the crane carriage is a trolley traction mechanism which is arranged on the end part of the crane span structure; the trolley traction mechanism drives a winding drum set to rotate by virtue of a motor and a speed reducer, so that a steel wire rope wound on the winding drum set is synchronously collected and released to generate traction drive for driving the crane carriage to move. The traction type arch-bridge crane has the beneficial effects that: a mid-span part is high in lifting height, and a space utilization rate of a plant ceiling is increased; driving torque of the trolley traction mechanism is small, so that the crane carriage is safe and stable in operation, and relatively high in positioning precision; civil engineering construction cost can be reduced for a special occasion; and the design is compact, space usage is small and the space utilization rate is high.
