1、 Emergency Rescue for Large-Scale Power Outages, Lightning Strikes, and Blizzards

1.1 Inform personnel inside the elevator car that rescue operations have begun, and instruct them to cooperate with the rescue efforts, not to pry open the doors, and not to attempt to leave the car;

1.2 Cut off the main power supply to the elevator in the machine room, check whether the steel wire ropes and drive sheave are normal, and meet the rescue requirements for manual winding operation;

1.3 Confirm the position of the elevator car and counterweight, and select the landing floor where the elevator is to be leveled;

1.4 Rescue methods: For different elevators, refer to the following rescue methods:

1.4.1Traction elevator with machine room

1.4.2 Traction elevator without machine room

1.4.3 Hydraulic elevator

1.5 Request support: If the above methods cannot complete the rescue operation, report to the on-site emergency rescue command headquarters of the unit and request support;

2、 Emergency Rescue for Earthquakes and Typhoons

2.1 Elevator seismic sensor activation

2.2 Elevator manual winding operation under feasible conditions

2.3 Elevator manual winding operation under infeasible conditions

3、 Elevator Seismic Sensor Activation:

3.1 Inform personnel inside the elevator car that rescue operations have begun, and instruct them to cooperate with the rescue efforts, not to pry open the doors, and not to attempt to leave the car;

3.2 Inspect the elevator to confirm that other components of the elevator and the building are basically normal and meet the basic operating conditions;

3.3 Refer to the elevator manufacturer's instructions to reset the activated elevator seismic sensor and restore operating conditions;

3.4 Rescue personnel operate the elevator in inspection mode to complete the rescue operation;

3.5 If the rescue operation cannot be completed, report to the on-site emergency rescue command headquarters of the unit and request support.

4、 Elevator Manual Winding Operation under Feasible Conditions:

4.1 Inform personnel inside the elevator car that rescue operations have begun, and instruct them to cooperate with the rescue efforts, not to pry open the doors, and not to attempt to leave the car;

4.2 Cut off the main power supply to the elevator in the machine room, check whether the steel wire ropes and drive sheave are normal, and meet the rescue requirements for manual winding operation;

4.3 Confirm the position of the elevator car and counterweight, and select the landing floor where the elevator is to be leveled;

4.4 For different elevators, the corresponding manual winding methods may be selected:

a. Traction elevator with machine room

b. Traction elevator without machine room

c. Hydraulic elevator

4.5 If the rescue operation cannot be completed, report to the on-site emergency rescue command headquarters of the unit and request support;

5、 Elevator Manual Winding Operation under Infeasible Conditions:

5.1 Elevator with machine room:

5.1.1 Inform personnel inside the elevator car that rescue operations have begun, and instruct them to cooperate with the rescue efforts, not to pry open the doors, and not to attempt to leave the car;

5.1.2 Cut off the main power supply to the elevator in the machine room, confirm the position of the elevator car and counterweight, and select the landing floor where the elevator is to be leveled;

5.1.3 Use two manual chain hoists (the lifting capacity of each chain hoist should be determined based on specific conditions, with a safety factor of at least 2.0) to hang them separately at secure and reliable positions in the machine room. Use more than three wire rope clips to secure the wire rope sling to the hoist chain. Each chain hoist should lift half of the traction steel wire ropes, forming a configuration of two chain hoists lifting one elevator car;

5.1.4 Pull both chain hoists upward simultaneously, and the elevator car will move toward the nearest floor. When the car is confirmed to be leveled, stop the pulling operation, but the hoist chains must be manually tied off to prevent slipping, and a maintenance personnel member should supervise;

5.1.5 Rescue personnel open the elevator landing door/car door at the leveled position to complete the rescue operation;

5.1.6 After personnel are rescued, if the landing door lock is damaged and cannot secure the landing door, maintenance personnel should tie the landing door shut with wire to prevent others from accidentally falling into the hoistway;

5.2 Elevator without machine room:

5.2.1 Inform personnel inside the elevator car that rescue operations have begun, and instruct them to cooperate with the rescue efforts, not to pry open the doors, and not to attempt to leave the car;

5.2.2 Cut off the main power supply to the elevator, confirm the position of the elevator car and counterweight, and select the landing floor where the elevator is to be leveled;

5.2.3 Use two manual chain hoists (the lifting capacity of each chain hoist should be determined based on specific conditions, with a safety factor of at least 2.0) to hang them separately at secure and reliable positions. Use more than three wire rope clips to secure the wire rope sling to the hoist chain. Each chain hoist should lift half of the traction steel wire ropes, forming a configuration of two chain hoists lifting one elevator car;

5.2.4 Pull both chain hoists upward simultaneously, and the elevator car will move toward the nearest floor. When the car is confirmed to be leveled, stop pulling the chain hoists, but the hoist chains must be manually tied off to prevent slipping, and a maintenance personnel member should supervise;

5.2.5 Rescue personnel open the elevator landing door/car door at the leveled position to complete the rescue operation;

5.2.6 After personnel are rescued, if the landing door hook lock is damaged and cannot secure the landing door, maintenance personnel should tie the landing door shut with wire to prevent others from accidentally falling into the hoistway;

5.3 If the rescue operation cannot be completed, report to the on-site emergency rescue command headquarters of the unit and request support.
