<P>PROBLEM TO BE SOLVED: To prevent over-warming of a control cable by supplying a current to warm up the control cable from a regenerative current from a take-up motor. <P>SOLUTION: This control cable device 50 includes a control cable 20 installed in a hoistway 2 and wiring a control board 10 with a car 7 of an elevator, a nichrome wire 34 installed inside the control cable 20 and warming up the control cable 20 by conducting a current, a temperature detector 58 detecting the temperature of the control cable 20 and generating temperature detecting signals, a transistor 64 for a heater for flowing the regenerative current from the motor 3 driving the car 7 in the nichrome wire 34, and a control part 60 for controlling the current flowing in the nichrome wire 34 from the transistor 64 for the heater based on the temperature detecting signals. <P>COPYRIGHT: (C)2011,JPO&INPIT |
