The elevator stops on a certain floor for a long time without moving or responding to external calls: it is possible that the elevator administrator has activated the driver operation function.
In daily life, elevators are a commonly used tool that brings us a lot of convenience. But how much do you know about the types and safety knowledge of elevators?
SOST.It is not recommended to force doors or self rescue from car roof safety windows. Because climbing out of the car is not equivalent to rescue, most passengers are unfamiliar with the elevator shaft and elevator structure, and blind self rescue often poses greater danger.
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.
.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.
The elevator stops on the first floor and the door does not move: the fire emergency landing function of the elevator is triggered by smoke or thermal sensors inside the building.
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, it is cut off
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.
The safety monitoring machine room environment screen cabinet main power switch traction wheel speed limiter shaft and pit guide rail layer door and car counterweight should be reliably fixed with pressure plates to prevent loosening.
Slide elevators are installed inside buildings and are often used parallel to buildings and sidewalks
Latest consultation.The gantry elevator is used in the door legs of large gantry cranes to transport workers and maintenance components inside the gantry crane
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.
These phenomena are not elevator malfunctions. When the elevator is fully loaded, the elevator does not stop: to avoid overloading, and the button on the chair handle causes the power drive device at the bottom of the chair to drive the person chair up and down along the guide rail of the staircase railing
Marketing Department.The elevator stops on the first floor and the door does not move: the fire emergency landing function of the elevator is triggered by smoke or thermal sensors inside the building.
The important components of elevators require certain technologies, 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,SOSTHousehold elevator, voltage regulation, and speed regulation, and adopts light curtain protection. Safety components such as safety gear, speed limiter and buffer must be manufactured.

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.
