The present invention provides a rope climbing elevator system (30) comprising: an elevator car (110); host upper diverter pulleys (120a, 120b); a tensioner (160); host lower diverter pulleys (150a, 150b); ropes (130a, 130b); and a counter-rotating paired drive pulley (141). A ratio of linear speed of the first drive pulley (141a) and the second drive pulley (141b) to movement speed of the car (110) is about X:1 in the climbing process, wherein X is larger than or equal to 2. The elevator system (30) can achieve a ratio of a linear rotation speed of a drive motor to a movement speed of an elevator car, larger than or equal to about 2:1, can lower the torque requirement for the drive motor, decrease the weight of the drive motor, and reduce the cost of the drive motor.
