Easily pick up the door or go up the ceiling to "escape"
The elevator has two doors, one is the hall door and the other is the car door. An automatic locking device is installed on the hall door. Once locked, unless the elevator car runs in place and the hall door and car door overlap, the mechanical lock hook will be locked. It cannot be opened. In the event of an emergency, only the qualified personnel can open the lock hook with the special triangular key to open the hall door.
The scene of pushing up the ceiling and climbing out of the elevator is often performed in the movie, which is quite exaggerated. Although there is an emergency exit on the top of the elevator, the lighting ceiling needs to be opened and a special key is required to open it. Moreover, the top of the elevator car is where the maintenance personnel work. There are only working railings around. Unfamiliar passengers get on by mistake. Not only can they not escape the hoistway, but it is even prone to danger and injury.
If the elevator fails, it will suddenly fall
The vertical elevator has a complete protection device, which is normally maintained and will not fall suddenly. What passengers call "sliding ladder" and "sliding ladder" is actually an illusion. The elevator has at least three security devices.
First of all, elevators have brakes. When there is a failure or power failure, the brake will lock the traction motor to stop rotating to ensure the elevator. Secondly, the upper and lower limit check switches and forced deceleration switches are set in the elevator shaft. If the elevator runs to the upper and lower ends, the elevator system will enter the forced deceleration and setting state. Third, when the overspeed governor detects that the elevator is overspeeding, the caliper brake is linked and the car is stuck on the guide rail. It is like two big pliers, once the elevator slides down at an excessive speed, it will cling to it to prevent it from falling. In case the elevator descends quickly to the ground floor, there is still a buffer at the bottom of the elevator to slow down the impact of the elevator when it landed. During the operation of the elevator, if a minor fault causes a problem with the elevator floor detection signal, the elevator will enter the protection restart state, automatically stop the corresponding button command, and reset the floor data by returning to the bottom or high floors. In this process, passengers cannot control the elevator, and the elevator has been running, so everyone mistakenly thinks it is the elevator "sliding ladder" or "slide".
Why the floor display screen becomes the 6th floor from the 8th floor
In fact, when the elevator is running, the number corresponding to the floor displayed is not very accurate. When the elevator is running, it starts, accelerates, decelerates, and stops according to a specific operating curve for the sense of passengers. "Especially for high-speed elevators, the operating distance is more than 3 meters per second at the high-speed stage, which is greater than one floor height. However, for the passenger's perception of taking the elevator, the displayed floor numbers are superimposed at a uniform speed, so that passengers will not think that the elevator is unexpected Fast and slow. When a fault occurs, if the elevator is in the process of starting acceleration or deceleration, there is a certain error between the actual position and the digital display floor. After the elevator self-protection stops, the floor display will automatically switch to the actual position. At this time, the passengers mistakenly thought that the elevator suddenly dropped several floors. In fact, the elevator stopped within the normal braking distance without slipping.
An elevator failure is an accident
It is possible that some citizens may hear abnormal noises when taking the elevator, or the elevator car shakes slightly during the operation of the elevator. You don't need to panic when encountering this situation. According to reports, the elevator will inevitably have a variety of situations during operation, such as abnormal noise, jitter, emergency stop, and even trapped people, etc. These are just elevators malfunctioning during operation, not elevator accidents. Elevator accidents are strictly and clearly defined. According to the relevant laws and regulations on special equipment, elevator accidents can only be regarded as elevator accidents if the elevator car has people stranded for more than 2 hours and the elevator causes serious injury, death or major property damage.
Elevator shut down = elevator accident
During the operation of the elevator, when encountering a sudden power failure and being trapped, most people's reaction was "I have encountered an elevator accident again." However, some analysts say that elevator closing is actually a protective measure for passengers.
During the operation of the elevator, when the detection system finds that the elevator has problems such as abnormality or failure, it will automatically make a normal response to protect the passengers, and then the person will be shut down. Power failure is essentially a phenomenon in which the elevator stops operating when there is no electricity, and the elevator car is parked in the hoistway. Passengers locked in the elevator, at this time yes, maintenance personnel only need to manually crank the passenger to release the passengers.
In the event of an emergency situation such as elevator trapping, first, press the emergency alarm button to contact the staff on duty of the property management company; second, call the rescue number of the maintenance unit; if the contact fails, immediately call the elevator emergency number 96333 to ask for help. Remember, under no circumstances should you engage in dangerous behaviors such as climbing the car top or forcibly opening the car door.
