When lubrication is performed at 0 and 11 and the car 7 arrives at the landing 61 on the first floor, the normally closed contact 1Pb is opened and the operation relay 1c of the relay circuit 1D is deenergized. In this state, the control device is driven again by the operation relay 9c of the relay circuit 9D,
The car 7 is driven upward from the first floor landing 61 to the ninth floor landing 69. In this way, the car 7 repeats the round-trip operation between the first floor landing 61 and the ninth floor landing 69,
At 30:30, the timer T stops operating, the normally open contact Ta is opened and the relay A is deenergized, so that the normally open contacts Aa and 1Aa2 are opened and the operation relays 1c and 9c are deactivated. For this reason, the driving of the control device by the relay circuits 1D and 9D is stopped, and the car 7 is guided to the first floor landing or the ninth floor landing by the control device. . At 1:00 am of the next day, the reciprocating operation between the first floor landing 61 and the ninth floor 69 landing started as described above, and at 1:30 am, the reciprocating operation was stopped and the elevator was put into a halt state. Become.

As described above, according to the embodiment, at a predetermined time every day (1:00 am), the elevator car 7 moves between the first floor, which is the lowest floor, and the ninth floor, which is the highest floor, for a predetermined time. (30 minutes), the elevator is operated for maintenance. For this reason, even at an elevator with a low operation frequency, a maintenance operation is performed for a predetermined time at a predetermined time every day, and the oil rail 12 of the car 7 and the oil rail 13 of the counterweight 8 respectively receive the guide rails 10, Since the lubrication is performed on the guide 11, the rust is not generated on the guide rails 10 and 11 even if the operation frequency is low, and the guide rails 10 and 11 are abnormally worn due to the operation of the elevator. Is done. Since this maintenance operation is not affected by the ambient temperature and the like and is always performed automatically at a predetermined time every day, the maintenance staff does not need to go to the site and the maintenance operation cost is greatly reduced.
