First, the elevator is trapped
- Pull the main power of the elevator open to prevent the elevator from starting unexpectedly, but the car lighting must be kept.
- Determine the elevator car position.
- When the elevator stops at a range of ±60cm from a leveling position, rescuers can use the special hall key to open the hall door outside the hall door of the leveling floor, and open the car door by hand, then assist the passengers to evacuate. Car.
- When the elevator does not stop at the above position, you must use the mechanical disk method to move the car and save the person. Steps:

(2) Mounting the cranking device on the tail end of the traction motor.
(3) Two people hold the turning device to prevent the elevator from accidentally or too fast moving when the mechanical lock is held, and then another person uses the loose brake device to loosen the brake. When the brake is released, the other two force The cranking device is twisted to move the car in the direction of the marking.
(4) Move the car intermittently to the level of ±15cm in the flat layer according to the direction indicated.
(5) Return the brake to normal, and then use the door key to open the car outside the door corresponding to the car door, and assist the passenger to withdraw the car.
- When abnormal conditions are found according to the above methods and steps, the rescue should be stopped immediately and the elevator maintenance and repair service should be notified in time.
