Of the two, the one with the higher lifting load falls. The speed due to the descent is detected by the speed detector 7 of the hoisting machine 3,
A predetermined speed at which the descending speed is gradually accelerated, but the detected speed is less than the operation value of the emergency stop device 15 of the car 8;
That is, when the speed V1 shown in FIG. 4 is reached, the predetermined speed detecting means 17 operates. By this operation, the rescue operation relay 1
8, the normally closed contact 19 is opened. Therefore, even if the rescue operation button 22 is pressed, the electromagnet 28 of the electromagnetic brake 6 is deenergized, so that the drive sheave 5 is braked and the car 8
Stops.

8 protrudes and returns to the state shown in FIG. For this reason, during the rescue operation for lowering the one of the car 8 and the counterweight 10 with the heavier load, the lowering is accelerated and the speed of the drive sheave 5 is increased before the speed reaches the operation value of the safety device 15.
Again, the foot pedal 37 of the traction device 34 can be immediately depressed again from the state where is braked. For this reason, the rescue operation can be repeated in a short time, and the work efficiency of the rescue operation can be improved.

果がある。Thus, when the elevator breaks down and stops abnormally, the rescue operation of the passengers in the car is performed as described below. That is, the rescue operation control device is operated by a staff member to release the electromagnetic brake of the hoist,
The one with the heavier suspending load of both the car and the counterweight descends. Then, the lowering speed is gradually accelerated, but when the lowering speed reaches a predetermined speed which is less than the operation value of the emergency stop device of the car, the predetermined speed detecting means operates. Through this operation, the electromagnetic brake of the hoist is braked by the rescue operation control device. For this reason, even if the car is accelerated during the rescue operation in which the car is lowered due to the difference in the suspended load from the counterweight, the hoist is braked before the speed reaches the operation value of the safety gear. As a result, the emergency stop device does not operate during the rescue operation for lowering the car, and the car can be stopped quickly and easily at the landing, which has an effect of facilitating the rescue operation of the passengers in the car.
