What is the role of the elevator emergency equipment?

Many people don't have a clear idea about the role of elevator emergency equipment. It seems that in our daily life, there seems to be no big requirement for the use of this device. In our daily life, we do not need to use it. In fact, an idea like this is very wrong. We will find many places of voltage is not very stable, especially in summer, people demand for air conditioners is relatively large, so there will often be the occurrence of power tripping. Once the power trip, the elevator can not run, for the elevator people in the safety of the inside, can not be guaranteed.
If the elevator is equipped with a special elevator emergency equipment, the elevator can also run in the emergency process, so its safety can be effectively guaranteed. Besides, we will find that if there is enough rain in summer, if there is long-term rain soaking in the ladder well of the elevator, there may be a lot of water. Then in the elevator, it is likely that these will affect the normal operation of the water lift, and may cause the elevator suddenly shut down.
But if the elevator is equipped with a special elevator emergency equipment, it can play its most important role at this time. The use of elevator for our safety performance is guaranteed.
