Why can't the escalator go because of power failure?

The escalator couldn't go because of power failure, which led to an accident.

The reason why the walking elevator can't go directly after power failure is that the steps or pedals of this elevator are connected in a circle and run circularly. When the elevator stops running, the power supply is cut off by the braking function of the elevator main engine to keep the transmission system stopped, so that the steps or pedals are no longer driven. If you go directly after the power failure, the phase will put pressure on the brakes. When this force exceeds the braking force, it is very likely that the brakes will fail and the elevator will slide down, leading to an accident.

The escalator is dead. There must be something wrong with it. In general, there are staff at one end of the escalator. Call them and they will come up to help you. If you can't call someone, it is recommended to walk up slowly and leave by yourself. Be careful not to rock the escalator back and forth.

Escalators cannot be used as ladders.

Escalators are steeper, narrower and higher than stairs, and are not suitable for walking. According to the relevant information, all kinds of building standards require that a rest platform should be set when the continuous stair step exceeds 18. However, escalators are usually more than 20 steps in a row. If it is used as stairs, it does not meet the design requirements of stairs, and there will be hidden dangers, especially for people carrying heavy objects. ?

Moreover, the escalator steps are generally provided with grooves, which will cause optical illusion, and it is easy to fall and get injured by stepping on the wrong steps when walking on them. Be aware that there may be safety hazards when the escalator stops. When the escalator is out of service, there may be reasons such as being under maintenance, not being inspected due, unqualified inspection, cancellation of use, etc. Xinlin Elevator, an expert on active safety elevator, suggests that users or maintenance units take isolation measures and set warning signs. At the same time, I also remind everyone not to use escalators as stairs at any time.
