1、 The correct use of elevators

1. 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 to avoid useless car stops and reduce the overall transportation efficiency of the building elevator. At the same time, this is also to avoid incorrect operation of safety devices, which may cause passengers to be trapped in the elevator car and affect the normal operation of the elevator.

2. When the elevator door is opened, do not place your hands on the door panel to prevent finger injury when the door panel retracts. When the elevator door is closed, do not place your hands on the edge of the door to avoid affecting the closing action or even squeezing your fingers. When taking care of children, one should use their hands to hold or hold them tightly while riding in the elevator.

3. When taking the elevator, a certain distance should be maintained from the elevator door. For safety reasons, as the elevator door is connected to the shaft during operation, the relative speed is very fast. If the elevator door fails, passengers near the door will be very dangerous.

4. Don't jump in the elevator. There are many safety protection switches installed on the elevator car. If jumping inside the elevator car, the car will tilt severely, which may cause the protection switch to act and put the elevator into a protected state. Once this situation occurs, the elevator will stop urgently, causing passengers to be trapped.

5. Many people are accustomed to using their bodies to block the door when entering. Although it is not dangerous, if you press it for too long, the elevator control part will think that the elevator has malfunctioned. It may sound an alarm or even stop. So the more appropriate approach is to press the door open button after you enter.

It should be noted that some people stand completely at the elevator door, blocking it, which is very dangerous. Because it is safe inside the elevator and also safe outside. But when you stand at the junction of these two spaces, if there is a situation called opening the door and walking the car at this time, the person will be cut off. So this is a very dangerous location and one should not stop at this junction.

6. It is not allowed for some units to use a freight elevator as a passenger elevator.

The difference between a freight elevator and a passenger elevator is that their decoration or comfort may be inferior. There are no special requirements for the indicators of vibration and noise. There is another type of cargo elevator that cannot be used as a passenger elevator, which is oversized. Because sometimes the products made in the factory are relatively light and they want the elevator car to be made larger, with the approval of relevant departments, the area of this elevator car is larger than the standard. If this type of freight elevator is used as a passenger elevator, it will experience overload.

2、 Safety knowledge after elevator accidents

1. When a falling accident occurs, the first step is to secure one's body. When such an impact occurs, it will not cause falls or injuries due to unstable center of gravity. Secondly, it is necessary to use elevator walls as spinal protection, which can be closely attached to the wall to provide a certain degree of protection. Most importantly, one can use knee bending to withstand heavy impact pressure. This is because ligaments are the only elastic tissue in the human body that can withstand pressure better than bones. Therefore, the correct protective action is to keep your back tightly against the inner wall of the elevator, bend your knees, and tiptoe up.

2. The bottom of the elevator refers to the situation where the elevator car, in the event of a complete failure of the control system, will miss the first level position and drive downwards until it stops on the buffer of the pit. This kind of situation rarely occurs, but once it happens, the consequences can be very serious, and the huge inertia may lead to fractures of the entire body of passengers, endangering their lives. In fact, if the elevator suddenly drops rapidly during the descent process, the safety protection device of the elevator will stop it. It is worth noting that the distance from the beginning of the elevator's fall to its stop is related to the elevator's load, so overloading is strictly prohibited when taking the elevator.

3. Self rescue measures when trapped in an elevator. After the emergency stop, the elevator also has several reliable and meticulous protective devices to protect the safety of passengers, so there is no need to worry about it continuing to fall. There are many reasons for suddenly stopping the elevator, and any attempt to escape without knowing the reason is considered a risky action. When you are just trapped, if there is no alarm phone inside the elevator, you can knock on the door or shout with your shoes. If trapped for a long time, the safest approach is to remain calm, conserve energy, and wait for rescue.

4. How should elevator managers rescue trapped individuals. When an elevator trapping accident occurs, the elevator management personnel contact the trapped passengers by phone or shouting. Be sure to keep it calm and patiently wait for the repair personnel's rescue. When the elevator car is far away from the elevator landing, enter the machine room and turn off the elevator power switch. Install a handwheel on the elevator shaft. One person should firmly hold the handwheel, while the other person should hold the brake release lever and gently pry open the brake. Pay attention to the leveling signs and gradually move the elevator car to the closest position to the hall door. When confirming that the braking is correct, use the landing door key to open the landing door and car door, assist passengers in leaving the car, and close the hall door again.

It is worth noting that some elevator workers, upon arrival, directly open the inner or outer doors of this elevator. Then, when you reach the parking level, sometimes you can't reach it and jump off, which is a very common practice in daily life. But this is a very non-standard rescue behavior, because the elevator is parked in a position where it should not have stopped, indicating that its system has malfunctioned. So if you open the door without cutting off the power, in case the elevator malfunctions again, passengers will be in danger.

Safety Tips for Riding Elevators

1. Please improve the efficiency of elevator operation by pressing the buttons on the floor you want to reach.

2. Please do not overload when taking the elevator.

3. Please do not lean against the landing door when taking the elevator.

4. Please do not smoke, play, crowd, or collide in the elevator car to avoid accidents.

5. It is strictly prohibited to transport flammable and explosive hazardous materials. In case of special circumstances, approval from relevant management departments and necessary safety protection measures must be taken before shipment.

6. Don't press the emergency button casually. The emergency button is set to deal with unexpected situations. When the elevator is running normally, do not press the emergency button to avoid unnecessary trouble.

7. If the elevator door is opened and the floor of the elevator car is uneven with the floor, it indicates that the elevator has malfunctioned. Please stop riding and wait for the relevant department to handle it.

8. If an elevator malfunctions and stops running while riding, the following measures should be taken:

Step 1: Stay calm, stabilize your emotions, and do not climb out of the elevator on your own;

Step 2: Find the emergency alarm device inside the elevator and seek help from the outside world through the alarm device;

Step 3: Check the distress phone provided inside the elevator and dial it to seek help outside;

Step 4: After sending out a distress message, take relevant measures under the guidance of professional personnel. Do not take wrong self rescue actions such as prying or prying doors without authorization. Wait for professional personnel to open the door for rescue inside the elevator. After leveling the elevator, quickly leave the elevator under the guidance of professional personnel.

9. Do not take the elevator in the event of a fire. When a fire occurs, passengers are prohibited from using elevators for escape and should choose the staircase safety exit for escape.

Is it safe to take the elevator?

The elevator has a car and a counterweight, which are connected by a steel wire rope. The steel wire rope is driven by the traction device (traction machine) to make the elevator car and counterweight move up and down on the inner guide rail of the elevator.

Taking the elevator

Elevators are essential vertical transportation tools in high-rise buildings, and they are large-scale comprehensive equipment that integrates mechanical and electrical systems. To ensure its safety and reliability, elevators have installed preventive measures from multiple 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 interlocking device, emergency stop switch, overspeed protection switch, overload protection switch, limit switch, emergency stop switch, safety window switch, etc. Mechanical safety devices include brakes, speed limiters, safety tongs, buffers, door hook locks, door safety touch plates, etc. These safety devices can ensure the safe operation of the elevator. Introduce elevator related knowledge in a question and answer format.

How does an elevator operate?

The elevator has a car and a counterweight, which are connected by a steel wire rope. The steel wire rope is driven by the traction device (traction machine) to make the elevator car and counterweight move up and down on the inner guide rail of the elevator.

Will the steel wire rope of the elevator break?

The steel wire rope elevator used for elevators is specialized and has specific national regulations and requirements. The configuration of steel wire ropes is not only for bearing the elevator car and rated load capacity, but also takes into account the magnitude of traction force. Therefore, the tensile strength of steel wire ropes is greatly greater than the load capacity of elevators, and their safety factors are all above 12. Generally, elevators are equipped with four or more steel wire ropes, and the steel wire ropes will not break at once.

Is there a danger of sudden power outage during elevator operation?

If there is a sudden power outage or power supply line malfunction during elevator operation, the elevator will automatically stop running without any danger. Because the elevator itself is equipped with electrical and mechanical safety devices, once there is a power outage, the electric actuator will automatically brake, making the elevator unable to operate. In addition, if there is a planned power outage, the power supply department will notify in advance, and the elevator may stop running in advance.

What should I do if the elevator suddenly accelerates?

The operating speed of an elevator, whether it is up or down, should be within the specified rated speed range and generally not exceed the speed limit. If an overspeed occurs, there is an anti overspeed device in the elevator control system. At this time, the device will automatically act to slow down or stop the elevator.

Can the overload of the elevator car be automatically controlled?

The load capacity of elevators varies according to needs, and elevators can only operate within the specified load capacity. If it exceeds the limit, the elevator will automatically sound an alarm and cannot operate.

Will being caught while closing the elevator door cause harm to people?

During the closing process of the elevator, if the hall car door touches a person or object, the door will automatically reopen and will not harm people. Because there is an anti family switch on the door, once the door touches a person or object, this switch action prevents the elevator from closing the door, opens it again, and then closes it again. In addition, the closing force is determined by regulations and will not reach a certain level.

Can the lobby door of elevator 7 be opened?

The lobby door of the elevator cannot be opened outside the courtyard and must be opened with special tools (the installation tools are controlled by maintenance personnel). Passengers are not allowed to pry or open the door, as there is a risk of falling into the well.

How to summon an elevator?

When you need to take the elevator, you should select the direction button on the door panel in the elevator lobby. Press the up direction button and the down direction button. The elevator adopts a forward parking method in the control system. If the elevator is driven in the opposite direction and reaches this floor, it will not stop.

Are there any protective measures for squatting and hitting the top of the elevator?

When the elevator squats to the bottom, if all the control systems of the elevator car fail, it will surpass the position of the first floor and drive downwards until it stops squatting on the buffer of the pit. The buffer is a protective device set up for this purpose, which is divided into two types based on the different operating speeds of the elevator: spring type and hydraulic type. When the car squats on the buffer, it is called squatting on the bottom. At this point, the buffer has a relieving effect on the impact force of the elevator car, so as not to cause serious harm to passengers inside the elevator.

What should I do inside the elevator car when the elevator is not running properly?

When taking the elevator, if you find that the elevator is speeding or moving at a slower speed, you should press the red emergency stop button on the control panel. The elevator will automatically stop and notify the elevator maintenance personnel in a timely manner.

What should I do if I find an odor inside the elevator car?

When abnormal burnt smell is found in the elevator car, the red emergency stop button on the control panel should be pressed to stop the elevator, and the elevator maintenance personnel should be notified in a timely manner

What should I do when I find abnormal vibrations or scratches in the elevator?

When you find abnormal vibrations, vibrations, or scratches in the elevator while riding, you should press the red emergency stop button on the control panel to stop the elevator and promptly notify the elevator maintenance personnel.

What should be noted when an elevator suddenly loses power or malfunctions, and is trapped inside the elevator car?

When you are locked in the car, you should follow the instructions of the elevator driver. If there is no driver, you can contact relevant personnel through communication devices for rescue. Never forcefully pry at the door or jump out on your own, as it may cause danger.

What should be noted when entering the car?

When entering the car, if the elevator door is open, check if the elevator is in the level position or if the car is on the same level, especially when the light is not clear at night. Otherwise, it may cause injury.

Should 15 elevator installation and repair units and maintenance and operation personnel obtain corresponding qualifications?

Yes. Elevator installation, maintenance, and renovation units must obtain a qualification certificate issued by the Quality and Technical Supervision Bureau before they can engage in corresponding work; Elevator installation, maintenance, and operation personnel should obtain a special personnel operation certificate before taking up their posts.

What emergency situation can I call 110 in elevator 16?

When an emergency occurs in an elevator, if there is injury or distress (personnel are trapped in the elevator car and cannot find elevator maintenance personnel), they can call the 110 alarm number.

What should be said clearly when the elevator alarms?
