The invention discloses a traction device for reducing the load of a main shaft of a traction machine. The traction device for reducing the load of the main shaft of the traction machine comprises a traction wheel and two rewinding wheels, wherein the axes of the two rewinding wheels are symmetrical about the axis of the traction wheel, the axis the traction wheel and the axes of the two rewinding wheels are located in the same plane, and any angle can be formed between the plane where the axis the traction wheel and the axes of the two rewinding wheels are located and the horizontal plane. The traction device for reducing the load of the main shaft of the traction machine has the advantages that a steel wire rope passes through the two rewinding wheels in a rewound mode, the steel wire rope bypasses the traction wheels twice, the contact lines of the steel wire rope and the traction wheel are symmetrical about the axis of the traction wheel, in this way, the two sets of pulling force exerted on the traction wheel by the steel wire rope are in opposite directions, part of the force is counteracted, the load of the main shaft of the traction machine is greatly reduced, the traction machine can be designed to be smaller easily, and the manufacturing cost of the traction machine is reduced.
