From the message you asked, it is clear that you have no professional training. Therefore, it is not recommended that you do the same treatment for the elevator.

1. The faulty elevator has not yet entered the signal detection area of the 13th floor, so it displays 12;

2. The emergency unlocking device must be automatically reset, and turning it around is just a precautionary measure. If you pull it and can't open it, it means that the hook has been closed, and it is impossible to open it without a key;

3. There is no driving device on the hall door, and its opening is driven by the linkage of the power opening mechanism of the car door, so as long as it is closed, the hall door will not be automatically opened unless the car reaches the flat floor normally again;

4. If the car is not parked on this floor, no matter what the reason is the hall door is opened (such as maintenance, open like you, etc.), after the external effect disappears, the forced closing device (heavy hammer or spring) on the hall door will make the floor door automatically close and lock;

It's nice to have the door locked after it is closed, thank you.

First of all, it is shown on the twelfth floor, but the elevator is near the thirteenth floor, because the elevator does not reach the level position on the thirteenth floor. Secondly, the problem about the door lock is very simple, you can enter the car top to see, you use the triangular key to open the door outside, do not finish twisting, enter the top after calculation, let the door close automatically, and the lock hook of the door lock will definitely close. At this time, you have to use the triangular key to open the door outside, and there is a spring inside the triangular key that can be reset.

Thank you, hope it helps you a little.

Generally speaking, the hall door lock has a spring without returning to the ** motion reset, some need to rotate is the lock has a problem, such as stuck ash or rust can not be automatically reset, you can't open the means that it has been reset The hook lock has been locked, there is no problem.

Passengers should not be anxious and panicked, there is an alarm button in the elevator, press the button to report and close the alarm celery and talk to the duty room, inform the current situation, and the duty room will shoot the maintenance worker to check the suspected liquid for maintenance.

8. If there is a jump in the elevator, it should be a problem with the top-floor parts, and the professionals of the elevator company should be asked to repair it in time, otherwise it will be very dangerous. 8. If the elevator is regularly overhauled, such as once a month, it will not be easy to have problems. Hope the above answers can help you!

Bless you!

There are so many masters in the special inspection institute. If you ask any one, it's a "brick family".

1. Will the elevator be slow up and down when the door is not closed--- it will definitely not (unless you have illegally changed the route of the elevator, such as: the door lock is unintentionally or intentionally shorted.) In the early days (10 years ago), there was an emergency button in the elevator car, and when the emergency button was pressed, the elevator could be overhauled slowly up and down, but now it has been forcibly canceled, and this kind of button is not allowed to be set up).

2. I have the ins button here is the left driver's status,,, the att button is the right driver's state·--your statement is wrong, ins is the meaning of maintenance, att is the driver, maintenance is not able to select the floor on the selection panel, and the driver status can choose the floor on the selection panel.

1.In the case of system control, it is absolutely impossible. Because the opening of the hall door needs to be driven by the door knife on the car door.

That is, if the elevator is not on this floor, the hall door on this floor cannot be opened (that is, the hall door is actually opened from the inside). If the door on this floor is opened, the elevator will not be able to run if the door is not closed, let alone to other floors.

2.In the case of human manipulation, if the elevator stops on the 5th floor, the maintenance personnel can actually use the triangular key to open the hall doors of the other floors. At this time, it is actually more dangerous.

If you step into it, you will probably fall into the shaft ......Therefore, there is generally a prompt on the hall door, "Please confirm the position of the car before opening the hall door". In the elevator installation trial stage (generally when the house is built, the exterior wall ladder is dismantled during that period, and the elevator is used as a driver and freight elevator), in fact, there are still many examples of stepping into the hoistway.

Or, if the door is not closed properly, the maintenance personnel seal the door and lock the line, so that the elevator system thinks that the door is all closed, and it can also operate at this time. But the elevator is in an extremely dangerous situation. Therefore, the elevator generally does not close the line to run the fast train, at most it is at the speed of maintenance (generally used when checking the door lock.

Under normal circumstances, in accordance with the mandatory requirements of the special equipment safety regulations, in principle, there will be no phenomenon you said. But if you add the human factor, it may be possible. The first is to look at the mechanical part, whether the traction machine can lock the brake; Whether the wire rope is slippery or not.

In the absence of major mechanical failures and hidden dangers, this kind of thing will never happen if the hall door is not closed. It's best to find someone who understands to look at the hall door line, or the line of the control cabinet in the computer room, they are all halfway out of the house. Safety, human life.

Hey, it is also the sadness of the elevator maintenance industry, low salary, low quality, and maintenance personnel are replaced too frequently. Anyone who has a little ability, and a way out who wants to stay in this line, danger and can't earn money to support the family, now 80% of the company's maintenance personnel are out of work alone, novices are often afraid of inertia, and then do lazy stupid things.

It is impossible unless it is considered to be a short-circuit elevator door lock circuit.

Construction elevator is a common name on the construction site, and the professional name is construction elevator.
