The invention discloses a novel portal frame, and belongs to the field of building construction. A foundation, two horizontally-arranged lower supporting cross beams, two horizontally-arranged upper supporting cross beams, four supporting legs, a horizontally-arranged main truss and an electric hoist are included, the two lower supporting cross beams are arranged side by side and installed on the foundation, and the two upper supporting cross beams are located over the two lower supporting cross beams correspondingly. Each upper supporting cross beam is connected with the lower supporting cross beam located under the upper supporting cross beam through the two supporting legs, the two ends of the truss are connected with the two upper supporting cross beams, and the electric hoist is installed on the main truss. The novel portal frame is small in occupied area, easy to operate and few in installation procedure.
