Abstract
PURPOSE: To enable smooth operation of a hydraulic elevator by stopping an unloading operation of the elevator at oil temperature lowering time at time when an idle preventive timer is not operated, again unloading the elevator, and operating the elevator after oil temperature reaches predetermined value.
CONSTITUTION: When an oil temperature is lowered to predetermined point, an oil temperature detecting contact Y is closed to energize a relay A to thereby close its contact A1 so as to energize a relay M. Thus, a motor is rotated to start unloading operation of a hydraulic elevator. Simultaneously, an unloading operation timer TA starts counting via contact A2. This timer TA is set at shorter time than the time of an idle preventive timer. When its set time is elapsed, the timer TA is colsed to open the contact TA2 to thus deenergize the relay M to thereby stop the motor M. The contact TA1 operate an unload stop timer TB. After predetermined time is elapsed, the motor M is again operated to increase the oil temperature.
