电梯It is a "means of transportation" commonly used in daily life. Xiaobian has sorted out some elevator cold knowledge for you, hoping to help you safely take the ladder and better care for the elevator。
1. Why are passenger elevators and freight elevators used separately?
      Separate use of passenger and freight elevators is not only for beauty and speed, but also for safety。In fact,Compared to the freight elevator,The load capacity and internal structure of the passenger elevator are quite different,If the passenger elevator is used as a freight elevator,It is easy to cause partial load (such as: 1200 pounds of goods stacked to the back of the elevator,It is easy to cause the elevator box to tilt;The weight of 1200 pounds is distributed when transporting passengers,Will not cause the elevator to tilt),So passenger elevators are used to transport heavier goods,It is very easy to cause elevator failure。In the process of transporting goods, if the packaging of materials (such as plastic bags, wooden strips, strapping straps, etc.) falls into the elevator door and inside the elevator, the elevator will also easily cause a stop fault after operation。Therefore, when transporting large goods, please consciously use the freight elevator。
二、电梯Is it safe to put your hand in front of the door?

      Every elevator has a blind spot,If they don't, they'll keep the door closed,手会被夹! 我们常见的电梯分为光幕式电梯和触板式电梯,Curtain elevator is equipped with infrared transmitter and receiver on both sides of the elevator door,To sense if there is a barrier;The touch plate elevator is sensed by a protruding touch plate on the elevator door。But in fact, both kinds of elevators have a certain induction blind area, which can not achieve full coverage。The elevator is equipped with a special protection device to prevent door clamping, but the device must be activated within 50 mm of the active door to be closed。Therefore, using hands, feet, items, etc. to block the elevator door may be caught, and it is also easy to cause damage and failure of the elevator door。For safety, it is a good choice to use the elevator door opening button。

三、电梯Why do I feel dizzy when I run?
      In fact: instant dizziness is caused by changes in brain pressure。At the moment of operation, the elevator has a relatively large acceleration, and the blood in the body generates an acceleration opposite to the acceleration of the elevator in the vertical direction, so that the blood pressure, especially the brain pressure, changes accordingly, resulting in brain hypoxia。Each person's physical condition is different, and the sensitivity to changes in brain pressure is different, which leads to obvious vertigo in some people and no sense in others。
