Claim 9:
10. An elevator system, comprising:
an elevator car, which can move along an elevator hoistway;
a traveling cable, which is operably connected to the elevator car and can move along the elevator hoistway together with the elevator car; and
a plurality of the clamping devices according to claim 1, which are respectively arranged in the elevator hoistway in a moving direction of the elevator car and are aligned with the traveling cable respectively;
wherein in a downward movement process of the elevator car, if a swinging force of the traveling cable is not less than the first damping force, the traveling cable swings to enter the limiting space via the opening of the clamping device; and
in an upward movement process of the elevator car, if a resultant force of a traction force of the elevator car and the swinging force of the traveling cable is not less than the second damping force, the traveling cable is pulled by the elevator car to exit the limiting space via the opening of the clamping device.
