<p>An indirectly driving elevator comprises a lifting device (1), a counterweight (8), a car (9) and ropes (3,10) connecting them. Said lifting device is mounted on the base beam(2). One end of the driving rope (3) which is winding around the lifting pulley of lifting device is fixed on the bottom base of hoistway via a lower driving fixed pulley(6) and the lower driving movable pulley (5) of counterweight, and the other end of driving rope winds around the upper driving movable pulley (4) of counterweight and is connected to a tension device (14) fixed on the base beam of litting device. The hanging rope (10) on the car winds around the hanging fixed pulleys (13) which are mounted on the hanging beam and is directly fixed on the counterweight matched to the car. It has a reasonable design of structure and can realize an indirect driving of cars. The lifting force is not limited to the variable weight of car and the distance between the hanging points of ropes. Thus the car can be designed lighter and be decorated flexiblely. It can considerably reduce noise and improve the running quality.</p> |
