The invention discloses an anti-deflection portal crane. The anti-deflection portal crane comprises a portal and a traveling trolley arranged on the portal and further comprises a winch, a controller, a rigid fixed frame and a sliding frame. The fixed frame is connected with the traveling trolley. The sliding frame is in sliding connection with the fixed frame and can slide up and down along the fixed frame. A lifting hook is arranged at the lower end of the sliding frame. The winch and the traveling trolley can move synchronously. The winch is connected with the lifting hook through a rope. A sliding rail is arranged on the ground below the portal. Movable wheels are arranged at the bottom of the portal and slidably connected with the sliding rail. The controller is used for controlling the traveling trolley to move horizontally and controlling the winch to take up/pay off the rope. By the adoption of the anti-deflection portal frame, the working efficiency can be improved, labor intensity is relieved, and safety accidents are reduced.
