Disclosed is an elevator traction transmission system with constant traction capacity. The elevator traction transmission system with constant traction capacity is applied to a vertical lifting elevator system and solves the problem that the traction capacity of an existing system can be affected by the dead weight, the internal load and the balance weight of an elevator car. The elevator traction transmission system with constant traction capacity comprises the elevator car 1, fixed pulleys 2 mounted at the upper end and lower end, a balance weight and balance weight rack 4, and tractor traction wheels 5 at the top end; the elevator car 1, the fixed pulleys 2, the balance weight and balance weight rack 4 and the tractor wheels are connected through a linkage steel wire rope 6, a traction steel wire rope 7 and tension adjusting units at both ends into a system. The elevator traction transmission system with constant traction capacity is characterized in that, by adjusting the tension adjusting units 8 at both ends of the traction steel wire rope 7, the tension exerted on the traction wheels 5 by the traction steel wire rope 7 can be a constant value, so that a maximum constant frictional force, namely, a balance force can be formed between the traction steel wire rope 7 and the traction wheels 5, and further an elevator can work safely; the balance force avoids influence from the dead weight and the internal load of the elevator car 1 as well as the weight of the balance weight and balance weight rack 4, so that the car and the balance weight can be minimized in weight, and the volume of the balance weight can be changed according to the actual load of the elevator, and further the elevator can work stably and reliably and reduce energy consumption.
