When many people cooperate with the maintenance of elevators, they must concentrate their thinking on each other.
If you want to open the hall door with a triangular key, be sure to see the position of the car. Do not take for granted that the elevator must be in any position.
When opening the hall door into the car roof, it is not possible to close the door immediately. Firstly, place the inspection switch on the inspection file, press the emergency stop switch, turn on the car ceiling lamp, and close the hall door after the car top is stable.
When the top of the car is out, first the hall door must be opened, then the car top inspection switch, emergency stop switch and lighting switch should be reset one by one, and then the hall door should be closed after reaching the hall. (If the person stands outside the hall and can operate the above switch, the switch should be reset after standing outside the hall)
When the car is running, don't stick your body out of the bar. Do not work on a ride.
In the car roof, in the event that the elevator runs out of control, it must be kept calm. It should be able to grasp the things that can help and keep it in a safe place. It cannot attempt to open the door and jump out.
When working in the pit, the safety switch of the pit maintenance box should be cut off. When you climb out of the pit, make sure that the hall door is open before you can access the pit's safety circuit and then quickly climb out of the pit. (If the safety switch can be operated outside the hall, the safety switch should be turned on after the person climbs out of the pit and then closes again)
If you must short-circuit the door lock to check the elevator door lock failure, you must ensure that the elevator is in maintenance state. After checking, be sure to disconnect the door lock short cable before returning the elevator to its normal state.
When overhauling emergency lifts, when using emergency switches, be sure to keep the doors closed and prevent others from falling into the hoistway. When entering the pit, if the door of the first floor is to be opened, a warning sign or special person's care must be placed on the hall door to effectively prevent others from falling into the pit.
When it is necessary to cut off the power supply to overhaul the elevator, hang up the warning sign “Someone operates and prohibits closing”. When carrying out belt operation or using electric tools, it is necessary to do a good job of preventing electric shock.
