The invention discloses a double-host driving elevator which comprises a first tractor, a second tractor, a lift car, counter weights and a tractor steel wire rope. The first tractor and the second tractor are correspondingly arranged in a lifting shaftway or an elevator machine room. The lift car is arranged in the lifting shaftway and goes up and down along the lifting shaftway. The counter weights are arranged in the lifting shaftway and go up and down along the lifting shaftway. The tractor steel wire rope penetrates through the counter weights, the first tractor, the lift car and the second tractor in sequence. The number of the counter weights is two, and the two counter weights are placed on the two sides of the lift car or on the same side of the lift car. The lift car is hung in the lifting shaftway through the tractor steel wire rope according to the hanging ratio of 2n : 1. The counter weights are hung in the lifting shaftway through the tractor steel wire rope according to the hanging ratio of n : 1, wherein n is 1 or 2 or 3 or 4. The double-host driving elevator has the advantages that rope winding modes with different proportions are used for the lift car and the counter weights, so that the using requirements on the elevator under different conditions are met, and meanwhile the effects of cost saving and mounting convenience are achieved.
