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
Dongsheng.The effective support width of the upper and lower support beams should be greater than the width of the escalator truss, and there should be embedded steel plates.
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.
.Elevator does not close the door or repeatedly opens and closes the door: there are debris blocking the light curtain or door contact plate at the entrance or sill.

Tower style residential buildings above; Residential units and corridors with twelve or more floors; Other Class II public buildings with a building height exceeding 32 meters; High rise buildings with elevators exceeding 32 meters in height; The functional fire elevator has a front room. The area of the independent fire elevator front room is: the front room area of the residential building is greater than 5 square meters; The front room area of public buildings and high-rise factory (warehouse) buildings is greater than 6 square meters. When the front room of the fire elevator is shared with the smoke proof staircase, and the area of the shared front room in public buildings and high-rise factory (warehouse) buildings is greater than 10 square meters.
Elevator does not close the door or repeatedly opens and closes the door: there are debris blocking the light curtain or door contact plate at the entrance or sill.
How many?.Elevator Tip 1: Why elevators can trap people? Every elevator door on each floor has a safety switch,DongshengHousehold two-story elevator, which can trigger the elevator to shut down in case of any abnormality.

There are many similar situations in daily life such as forcefully opening the door inside the car, causing the circuit to disconnect and forcing the elevator to stop resulting in people being trapped. For example, if the elevator frequently enters and exits during decoration and falls into the crack of the door,DongshengAluminum alloy mast type lifting platform, the elevator hall door may not be tightly closed, and after several consecutive doors are opened and closed, the elevator will stop.

When accidentally trapped in an elevator, one should remain calm, press the alarm bell inside the elevator, and call the elevator emergency rescue phone or community property phone for help. Do not open doors or mess with buttons, and patiently wait for rescue.
Sincere service.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, such as the traction machines of passenger elevators and sightseeing elevators that are permanent magnet synchronous, and the car door machine that is frequency conversion, voltage regulation, and speed regulation, and adopts light curtain protection. Safety components such as safety gear, speed limiter, and buffer must be manufactured.
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.

The elevator suddenly descends to the bottom floor and resumes normal operation: After the elevator is powered off and reconnected, the leveling reference position needs to be re determined.
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, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally, it is cut off
