PROBLEM TO BE SOLVED: To properly perform the forced warming up and suppress the distrust given to a customer by releasing the operation of a door stop switch, when an oil temperature lower than a prescribed value is detected by an oil temperature sensor, and the operating state of the door stop switch is detected, and performing a warming up for circulating the hydraulic oil. SOLUTION: In an operation control device 32 for elevator, it is regularly read by an input part 24 whether a door stop switch 39 within a car 7 is operated or not, and when the switch 39 is operated, it is judged by a judgment part 35 whether the detected oil temperature of an oil temperature sensor 26 attached to a power unit 3 is less than a prescribed value A or not. When the oil temperature is less than the prescribed value A, it is judged whether the load quantity detected by a pressure sensor 17 is 0% or not, and a signal for canceling the operation of the door stop switch 39 is transmitted from a transmission part 36 to an elevator microcomputer 30 only in case of YES. According to this, a pump is driven so as to circulate the hydraulic oil by use of a circulating circuit, and a warming up is performed until the oil temperature reaches the prescribed value or higher. |
