When the ascending command relay contact (9) closes, the ascending operation relay (1K) is energized, and the contacts (lla) to (lie)
is closed and a voltage of K is applied to the motor (1). at the same time,
The brake coil O@ is energized by the battery O, the brake shoe is separated, and the electric motor (1) is released.Now the electric motor (1) starts, and as explained in Fig. 1, the electric motor (1) is activated. If 7) is 0 rising and (7) approaches the floor,
The contact (9) is opened, the upward operation relay (il) is deenergized, and the contacts (111L) to (Lla) are opened.
Okay, the electric motor (1) is cut off from power supply, and the shoe I during play.
The spring force applies braking force to the electric motor (1), so the car (7) stops.

Now, (+) −1JI −(21a) −H−(−
) is energized and the contact (
12a) + (12b) is closed and the motor (1) is connected to the power supply (8). At this time, the rotational speed of the train machine (1) has already exceeded the synchronous speed, so the electric motor'(
1) acts as a dynamic brake and generates a braking torque commensurate with the weight difference between the car (7) and the comb head (5),
The heel (7) is lowered at a constant speed.In order to increase the capacity of the electric motor (1), the weight of the counterweight (5) is increased and the weight is unwound from the lowering start waiting drum (3). Not only does this eliminate the risk of the main rope (4) coming loose, but power consumption is also saved because there is no need to supply K power to the starting special electric motor (1). ′
6, the synchronous speed is detected by the motor current, but this may be detected by the motor current.As explained above, in this invention, when the drum type elevator is operating downward, no power is supplied to the motor. , the brake is released and the car is lowered by its own weight, and when the motor reaches synchronous speed, power is supplied to the motor, so the acceleration on the motor side is higher than the acceleration on the car side. Looseness of the main rope and accidents caused by it can be prevented. Moreover, power consumption can also be saved.
