Do not light up both the up and down direction buttons at the same time
When calling the elevator, passengers only need to press the call button in the direction they are going. Do not press both the up and down direction buttons at the same time, so as not to cause useless cars to stop and reduce the overall transportation efficiency of the building elevator. At the same time, this is to avoid the wrong action of the safety device, causing passengers to be trapped in the car and affecting the normal operation of the elevator.
Do not jump in the elevator, it may cause an emergency stop of the elevator
Don’t jump in the elevator. There are many safety protection switches on the elevator car. If you jump in the car, the car will incline severely, which may cause the protection switch to act and make the elevator enter the protection state. Once this happens, the elevator will stop in an emergency, causing trapped passengers.
Try not to block the door with your body
Many people are used to blocking the door with their bodies when entering the door. Although it is not dangerous, if you press for too long, the elevator control part will think that the elevator has malfunctioned. It may call the police or even stop. Therefore, it is more appropriate to press the door button after you enter.
Special reminder is that some people stand at the elevator door and block the elevator door. This is very dangerous. Because the elevator is safe inside and safe outside. But if you stand at the junction of these two spaces, if this happens at this time, as the saying goes, the situation of opening the door and walking the car, this person will be cut. So this is a very dangerous position and should not stay at this junction.
Fix your body first when the elevator falls
When a fall accident occurs, the first thing to do is to fix one’s body. In this way, when the impact occurs, it will not cause fall injuries due to the unstable center of gravity. The second is to use the elevator wall as a protection for the spine, close to the wall, can play a certain protective role. Importantly, you can use the knee flexion to withstand the pressure of a heavy blow. This is because ligaments are the only elastic tissue in the human body and can withstand pressure better than bones. Therefore, the protective action of the back close to the inner wall of the elevator, the knees bent, and the tiptoes are correct.
Self-rescue measures trapped in the elevator
After an emergency stop, the elevator has several sets of reliable and thorough protection devices to protect the safety of passengers, so there is no need to worry that it will continue to fall. There are many reasons for a sudden stop. Before you know the reason, any behavior you try to escape is a risky move. When you are just trapped, if there is no alarm call in the elevator, you can slap the door and shout or knock with your shoes. If you are trapped for a long time, the safe course is to stay calm, save your energy, and wait for rescue. After sending out the distress message, take relevant measures under the guidance of professionals. Do not take erroneous self-rescue actions such as prying doors and digging doors without authorization. You should wait in the elevator for the professionals to open the door for rescue. Leave the elevator quickly under the guidance of the person.
If you find that the elevator is running with the door open, please do not ride
If you find that the elevator is running with the door open and the floor of the elevator car is not flush with the floor, it indicates that the elevator is malfunctioning. Please stop riding and wait for relevant departments to deal with it.
Do not take the elevator in the event of a fire
In the event of a fire, passengers are prohibited from using the elevator to escape and should choose the staircase safety exit to escape.
Is there any danger in a sudden power failure during elevator operation?
If the elevator encounters a sudden power failure or failure of the power supply line during the operation of the elevator, the elevator will automatically stop running without any danger. Because the elevator itself is equipped with electrical and mechanical safety devices, once the power is cut off, the electric actuator will automatically brake, making the elevator unable to run. In addition, if there is a planned power outage, the power supply department will notify in advance, the elevator may stop operation in advance.
What if the elevator suddenly speeds up?
The elevator’s operating speed, whether it is up or down, should run within the specified rated speed range. Generally, it will not overspeed. If overspeed occurs, there is an anti-overspeed device in the elevator control system. At this time, the device will automatically act. Decelerate or stop the elevator.
Can the elevator door be opened?
The elevator hall door cannot be opened outside the court, and must be opened with special tools (installation tools are controlled by maintenance personnel). Passengers are not allowed to pick up the door, let alone open it, otherwise there is a danger of falling into the well.
What should I do when the elevator is found to have abnormal vibration or scratching?
When you are riding in an elevator and find abnormal vibration, jitter, or scratching, you should press the red emergency stop button on the control panel to stop the elevator and notify the elevator maintenance personnel in time.
What kind of emergency can I dial 110 in the elevator?
When there is an emergency in the elevator, there are cases of injured or trapped people (people trapped in the elevator car and unable to find elevator maintenance personnel), you can dial 110 to report to the police.

Passenger elevator tips
2020年12月23日 お仕事"Elevators usually do not fall down. Even if they fall, they will not directly hit the ground. Since the bottom of the elevator is also equipped with a buffer device, the elevator falling down is the same as falling on a spring."
The elevator is relatively safe when people are trapped inside
Why did the elevator suddenly stop running? Many people think this is at risk. Originally, this was a way for the elevator to save itself.
When the elevator leaves the factory, many safety protection measures are installed. When the elevator cannot reach the request for normal operation of the elevator due to certain conditions, the elevator will stop running. If someone happens to be inside, it will cause trouble, so it is safe to stay inside when the elevator is stuck.
Some people worry that being trapped in the elevator will suffocate, which is not the case. The elevator is not sealed, there are vents on the top, and the hall door has gaps.
Of course, the trapped elevator can’t sit still. You must notify people outside to rescue you. You can contact the elevator rescue base and machine room through the intercom system, or dial 119 or 110 directly.
It is worth noting that you should never try to force open the elevator door. You may be trapped in the center of the floor. Forcibly opening may cause the elevator to start abnormally, or even risk falling into the elevator shaft.
Together, you can’t imitate the scenes in the TV series, don’t escape from the elevator ceiling. Once the exit board is opened, the safety switch will stop the elevator. However, if the exit board is accidentally closed, the elevator may suddenly start to lose balance, and there is a risk of falling off the top of the elevator.
Passengers should not force their hands on the car door
Elevators usually do not show "free fall" incidents. Each elevator has multiple wire ropes, with more than seven or eight, and there are more special elevators. Under normal conditions, each can accept the full weight of the elevator.
During operation, even if all the wire ropes are broken, the elevator’s speed-limiting safety equipment will work. The speed limit safety equipment will drive the safety gear on the elevator, force the elevator to clamp on the elevator guide rail, the safety gear can work even without electricity.
Due to factors such as power supply suspension, elevator failure, etc., the elevator suddenly stopped during operation. When trapped in the car, please wait quietly and do not act without authorization to avoid "cutting" or "falling well" incidents. Passengers should not forcibly grab the car door or try to collect and pay the car, but should try to get in touch with the outside world.
"Even if the elevator falls, it will not directly hit the ground. Since the bottom of the elevator is also equipped with a buffer device, the elevator falling is the same as falling on a spring." said a person in charge of Sanyo Elevator who participated in the activity.
After the incident, when the passengers in the elevator alarm, provide the outside world with basic conditions such as the number of people trapped in the car and their health status, whether the emergency light in the car is on, and the direction of the floor where the car is parked, so as to facilitate the relief operation.

Things you ca not do in an elevator
2020年12月9日 お仕事1. Press the button repeatedly
It is understood that when waiting for the elevator, people often press the button repeatedly. This behavior will cause the elevator to stop by mistake, which will delay others’ time and may cause the button to malfunction.
2. Stay at the elevator entrance
The elevator door is prone to accidents. It is dangerous to stay between the elevator hall door and the car door. Some passengers will stay for a short time when entering and leaving the elevator. It is very dangerous to chat with people. This is very dangerous. Yes, the way in and out.
Three, lean on the door
Many people like to rest on the door while waiting for the elevator, but if the elevator car is not on this floor when the elevator is opened, it is very easy to fall into the hoistway and there is a risk of being stuck by the car and hoistway!
Fourth, use items to forcibly prevent the door from closing
When the elevator doors are closing, passengers outside will prevent them from closing with their hands, feet, sticks and other objects. So wait for the next time or ask passengers inside the elevator to press the door button. People in the elevator should not stretch out their hands and feet, probe their brains, and should not put their belongings in the gap to prevent the elevator doors from closing. Pay special attention to the case of children, and parents should pay close attention to prevent children from being naughty.
5. Bring dripping rain gear into the elevator on a rainy day
This will not only wet the floor and easily slip, but also cause short circuit and other risks when water enters the hoistway along the gap.
6. Coins and other objects fall into the elevator and reach out into the gap with your hands or tools
Sometimes coins, necklaces and other objects fall into the gap between the elevator door and the hoistway when the elevator is parked. Please inform the elevator staff to assist in handling it immediately. Do not reach into the gap with your own hands or tools. It is dangerous to recognize it.
7. Bounce around in the moving car and press buttons randomly
This kind of behavior mostly happens to children. Sometimes they will take the elevator to play. When you go up, you press the button for each floor, and when you go down, you press the button for each floor. If a child has such a behavior, we must stop it and let the child get rid of this bad habit.
8. Weight overload
Generally, the load of an elevator is 1000 kg and it is limited to 12 people, but we can often see that it is crowded with people. In fact, this is quite dangerous. If there is an urgent matter, discuss it with others. If no one is willing, don’t squeeze, because a small drop of rain may cause a tsunami.
Nine, open the elevator by hand
When the running elevator suddenly stopped, many people forcibly opened the elevator door or tried to climb out of the window because of panic.

Elevator is an indispensable vertical transportation tool in high-rise buildings. It is a large-scale comprehensive equipment of mechatronics. In order to ensure its safety and reliability, the elevator has set up preventive measures from many aspects, such as electrical safety devices and mechanical safety devices. Among them, electrical safety devices include: power control protection device, power supply phase sequence protection device, door lock electrical interlock device, emergency stop ladder switch, overspeed protection switch, overload protection switch, limit switch, emergency stop switch, safety window switch Wait. Mechanical safety devices include brakes, speed limiters, safety gears, buffers, door hook locks, door safety touch panels, etc. These safety devices can ensure the safe operation of the elevator.
1. How does the elevator work?
The elevator has a car and a counterweight, which are connected by wire ropes. The wire rope is driven by the driving device (traction machine) to make the elevator car and counterweight move up and down on the elevator guide rails.
2. Will the elevator wire rope break?
The state has special regulations and requirements for steel wire rope elevators for elevators. The configuration of the wire rope is not only to bear the elevator car and rated load, but also to take into account the size of the traction. Therefore, the tensile strength of the wire rope is much greater than the load of the elevator, and their safety factor is above 12. Generally, elevators are equipped with There are more than four wire ropes.
3. Is there any danger in a sudden power failure during elevator operation?
If the elevator encounters a sudden power failure or failure of the power supply line during the operation of the elevator, the elevator will automatically stop running without any danger. Because the elevator itself is equipped with electrical and mechanical safety devices, once the power is cut off, the elevator brake will automatically brake, making the elevator unable to run. In addition, the power supply department will notify in advance if there is a planned power outage, and the elevator may stop operation in advance.
4. What should I do if the elevator suddenly speeds up?
The elevator’s running speed should run within the specified rated speed range regardless of whether it is up or down. Generally, it will not exceed the speed. If overspeed occurs, there is an anti-overspeed device in the elevator control system. At this time, the device will automatically start. Decelerate or stop the elevator.
5. Can the elevator car overload be controlled automatically?
The load capacity of the elevator is different according to the needs. The elevator can only run within the specified load capacity. When it exceeds the specified load capacity, the elevator will automatically alarm and cannot run.
6. Will being caught when the elevator closes the door will cause harm to people?
When the elevator door is closing, if the car door touches a person or object, the door will automatically reopen without hurting people. Because there is an anti-pinch switch on the door, once the door touches a person or object, this switch action prevents the elevator from closing, and reopens, and then closes the door again. In addition, the closing force is prescribed.
7. Can the elevator hall door be opened?
The elevator hall door cannot be opened outside the car, it must be opened with special tools (installation tools are controlled by maintenance personnel). Passengers are not allowed to pick up the door, let alone open it, otherwise there is a danger of falling to the bottom of the well.
8. How to call the elevator?
When you need to take an elevator, you should select the direction button you want to go to on the panel of the elevator hall. Press the up arrow button up, and press down the arrow button. The elevator adopts a forward parking method in the control system. If the elevator goes in the opposite direction, the elevator will not stop to this floor.
9. Are there protective measures for elevator squatting and topping?
Elevator squatting at the bottom means that when all the control systems of the elevator car fail, they will overtake the leveling position of the first floor and drive down until they squat on the buffer in the pit and stop. The buffer is a protective device set up for this purpose. This protective device is divided into two types: spring type and hydraulic type, depending on the operating speed of the elevator. When the car squats on the buffer, it is called squat bottom. At this time, the buffer has a mitigating effect on the impact of the elevator car, and will not cause serious damage to the passengers in the elevator.
10. What should I do in the car when the elevator runs abnormally?
When taking the elevator, if you find that the elevator is overspeed or slow, you should press the red emergency stop button on the control panel. The elevator will stop automatically and notify the elevator maintenance personnel in time.
