The send (27,35,70,77) communication check code to each other via a first communication channel, a predetermined time multiple car that moves in a hoistway same (A~C) is, (32, 38, no response was received 74, 81) in (30,37,73,80), the car that is not receiving the response, sending an abnormal mode instructions 2 Tsunokago the other (53,82). Any of the car given the car that senses an abnormal (A) or (B), and parked safely position deviating from the running path of 2 Tsunokago other; the (56, 57 85, 86) after the special under the control of a signal sent through the sensor such, the second communication channel, be a wild car mode is assumed. If 1 Tsunokago does cause communication error with 2 Tsunokago one or the other, it can be operated two of the 3 Tsunokago.
