おもりの調整用おもり片が加減される。In the elevator constructed as described above, the static balance between the car side and the counterweight side is inspected by the following operation. That is, a weight corresponding to the planned balancing load is loaded on the elevator car. Then, the elevator is operated and both the car and the counterweight are stopped at a position facing each other. In this state, a manual handle is attached to the rotating shaft of the hoist, for example, the shaft end of the electric motor, and the brake of the hoist is released to manually rotate the manual handle in both forward and reverse directions. If there is a sensible difference in the rotational resistance in both the forward and reverse directions, it is determined that the balance is poor. Then, the weight piece for adjusting the counterweight is adjusted.
