The closed section elevator pair reuse hollow guide rail, and the cross section of the guide rail is an inverted T shape with symmetrical shapes on both sides of the hollow; The bottom of the section is the section of the horizontal guide rail back, the sections of two guide rail surfaces equidistant from the midpoint are vertically arranged above the section of the guide rail back, and the sections of the guide surface parallel to the section of the guide rail back are arranged at the ends of the sections of the two guide rail surfaces to form a closed section. The beneficial effect is that the elevator has a closed section for reusing the hollow guide rail, The three guide surfaces of the hollow guide rail and the guide shoe lining plate are plane contact guide. In the process of cold bending and rolling forming of thin plate to manufacture the guide rail, the welding process is adopted to enhance the bending section modulus. The two ends and upper ends of the hollow guide rail are locally rounded chamfered to ensure the smooth connection of the adjacent two guide rails during installation. The cavity of the hollow guide rail is filled with polyurethane, It can reduce the noise in the car when the elevator is running, and can be widely used for counterweight guidance of elevator without safety gear with counterweight with load capacity ≤ 1000 kg and speed ≤ 1.75 M / s
