I believe everyone is familiar with the passenger elevator. It mainly carries the transportation function of high-rise buildings. Otherwise, few people can stand the hardship of climbing 30 floors every day. Since the elevator is so indispensable, I believe everyone must have a corresponding thirst for knowledge about the safety and reliability of the elevator. Passenger elevators are generally concerned about the vertical transport elevators in the community, so will there be a sudden fall during the up and down operation of the elevator? Will it hit the roof slab at an upward speed? I believe that partners who are not familiar with elevators must have concerns in this regard. Is the elevator safe?
In fact, the passenger elevator for vertical transportation is still very safe. Perhaps everyone lacks the knowledge of the elevator and can only see that the car runs vertically, but cannot see the situation outside the car inside the hoistway. Many people think that the elevator is hung on the hanging wheel. Once the suspension device breaks, the elevator will fall. Some friends will also say that he may encounter a situation where the elevator suddenly stops and then "falls down. In fact, these problems as long as we know more about the elevator is not afraid. Here to give you a rough popularization of elevator structure and safety knowledge.
First, the elevator is just like rail transit. There are one or more guide rails on both sides of the car. The elevator is stuck on the guide rails when running up and down, so there is no problem of collision with the hoistway. Moreover, there are mechanical and electrical switch detection for derailment. Once the left and right amplitude of the elevator is too large before and after operation, the elevator will report failure to stop operation. Therefore, injuries caused by collisions in the front, rear, left and right directions can be basically eliminated;

Second, the up and down operation of the elevator does rely on the suspension device to pull up and down, usually wire ropes and steel belts, but many wire ropes and steel belts exist together, and breaking one or two will not affect the safe operation, and For the special equipment of the elevator, a special person is assigned to maintain it once every half a month. All these safety items need to be checked, and the competent government departments also have supervision and spot checks. Therefore, it is basically impossible for the elevator to fall due to the fracture of the suspension device. Moreover, even if the wire rope is all broken, the elevator also has a brake device. The elevator car is equipped with safety gear, once the elevator overspeed, the speed limiter will make the safety gear action, firmly stuck on the guide rail. And the elevator pits are equipped with buffers, so many safety devices can not all fail at the same time;

Third, there is generally no need to worry about the problem of upward speeding and bumping. Because in the early stage of elevator installation and inspection, the top floor space is reserved at the top of the hoistway, which is to prevent the elevator from rushing to the top, and the host is equipped with an upward overspeed protection device.
Elevator for safety design is still very much, generally several protection measures, the same time all failure is basically impossible. The safety problems reported in the general news are caused by irregular elevator riding and irregular maintenance. Therefore, when you take the elevator at ordinary times, don't blindly save yourself when the elevator is broken. It is correct to call the maintenance telephone, the property telephone and the supervision department telephone to wait for rescue.
