The invention discloses a freight elevator driven by double traction wheels. The freight elevator driven by the double traction wheels comprises a lift car device, a counterweight device and a traction system with a traction machine, the traction machine comprises a traction motor and two traction wheels synchronously driven and controlled by the traction motor, the traction system further comprises two groups of traction ropes, two groups of lift car rope returning wheels are correspondingly fixed on the upper portion of the lift car device, two groups of counterweight rope returning wheels are arranged at the upper part of the counterweight device, after each group of traction ropes correspondingly wind around the corresponding traction wheel, and the two end parts of each group of traction ropes correspondingly wind around the corresponding lift car rope returning wheel and the corresponding counterweight rope returning wheel and then are correspondingly and fixedly connected with arope head frame at the top of a hoistway. According to the freight elevator driven by the double traction wheels, two groups of symmetrical traction systems are achieved through the two traction wheels, the traction force is increased, and the freight elevator is suitable for large-tonnage elevators; and the lift car device can correspond to the upper and lower center lines of the counterweight device conveniently, and the space arrangement is more reasonable.
