In Fig. 6 to Fig. 8, auxiliary pulley 91 remains in auxiliary pulley framework 92 freely rotatably, compensates rope 4 is erected on auxiliary pulley 91, auxiliary pulley framework 92 and auxiliary pulley 91 are driven on the direction orthogonal with guide rail 7 by the linear actuators 82 of actuator devices 53, change acts on the rope tension in the compensates rope 4 between tension pulley 5 and auxiliary pulley 91, changes the eigentone of compensates rope 4 thus.
Thus, can also reduce to vibrate by the antiphase between lift car 6 and counterbalanced weight 3 rope vibrations caused, and reduce the whirling vibration of generation on tension pulley 5, the up-down vibration of lift car 6 can be reduced thus effectively.300 represent actuator control part, and 302 expressions detect the rotation angle detector of the rotation of auxiliary pulley 91.
In addition, for convenience of explanation, for the common segment with the first embodiment, use the same reference numerals to represent, and omit the detailed description of above-mentioned part.
As shown in Figure 6, auxiliary pulley framework 92 is provided with the axle 71 be connected with connecting rod 55.Auxiliary pulley 91 is arranged on lift car 6 and tension pulley 5 or between counterbalanced weight 3 and tension pulley 5.
As shown in Fig. 7 A, 7B and Fig. 8, compensates rope 4 is erected between tension pulley 5 and auxiliary pulley 91.Auxiliary pulley 91 is arranged within the scope of the driving of linear actuators 82, also can contact with compensates rope 4 when the displacement of actuator reaches maximum displacement.
Fig. 9 is the block diagram of the circuit structure of the control part represented in the second embodiment.Actuator control part 300 has sensor part 301 and moment operational part 310 and drive control part 320.
