The braking system of the elevator is usually closed, which means it is in the braking state when there is no power, and only when it needs to be turned on, will the power turn on the brakes. So as soon as there was a power outage, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally, it is cut off

Will the elevator quickly fall during a power outage& mdash;& mdash; Some movies and TV dramas often mislead the public into thinking that if the elevator loses its power, it will lose control and engage in falling movements.
.2. Different types of civil engineering traction elevators, screw elevators, and hydraulic elevators have different requirements for civil engineering. Common traction elevators require a certain amount of hoistway space, which can be made of concrete, steel structure hoistways, and glass curtain walls to create sightseeing elevators; The depth of the pit should be at least 50cm or more; Additionally, there are certain requirements for the height of the top floor.
Factors to consider when choosing a household elevator: 1. Safety. Generally, brand elevators must have third-party testing, and elevators that have been inspected by professional organizations are safe, and guaranteed to be used with peace of mind. In addition, when choosing to purchase villa elevators, it is important to understand the safety components and configuration of this elevator. The essential safety equipment in the villa elevator includes a backup power supply and an emergency call outside telephone system to ensure the safety of private users on the elevator.
The elevator suddenly opens the door and does not move after leveling, but automatically resumes operation after a few minutes: The elevator (escalator) has been running for too long, and the motor overheats. To prevent burning out, the motor cools down and automatically resumes operation.
When passengers are riding on the escalator, they may lose their balance and fall due to leaning against the skirt board on the side of the escalator which does not move, but their feet move with the steps. Especially when carrying a lot of packages while taking the elevator, it is more likely to fall on the escalator due to the inability to hold the handrail properly. So, when riding on the escalator, and do not lean against the skirt board on the side of the escalator.
Dragging Method&ndash& mdash; AC dual speed Low speed elevators with frequency modulation and speed regulation often use AC dual speed (AC -) It changes the number of poles of the electric motor to achieve speed regulation,HelenAutomatic high-altitude reclaimer, allowing the elevator to have a low-speed operation process before the leveling brake, thereby reducing the impact of sudden deceleration during elevator leveling and improving passenger comfort. The advantages are fewer links and low failure probability, while the main disadvantages are poor comfort. The straight elevator starts frequently, and the impact current during startup is too high, increasing power consumption. This type of elevator is now commonly used for freight elevators.
Household elevators must be regularly maintained to confirm their safety and whether they can continue to operate, while also repairing any faults and hidden dangers found.

These phenomena are not elevator malfunctions. When the elevator is fully loaded, the elevator does not stop: to avoid overloading, the elevator car no longer responds to the next station's outbound call.
Elevator Tip 1: Why elevators can trap people? Every elevator door on each floor has a safety switch, which can trigger the elevator to shut down in case of any abnormality. The elevator getting stuck is actually when the system detects an abnormal signal and triggers a protective device like braking to stop.
