ShanghaiTractiThe braking system of the elevator is usually closed,ShanghaiPrice of hydraulic flipper, 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,ShanghaiFlip plate hydraulic roadblock machine, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally, it is cut off
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?
Shanghai.If the elevator is in a downward direction, immediately close the door and return to the first floor station, and automatically open the elevator door.
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.
.The difference between home elevators and ordinary public elevators is that the focus of home elevators and ordinary public elevators is different, with some indicators significantly reduced. For example,ShanghaiVertical hydraulic elevator, which is much lower than that of ordinary public elevators. Home elevators do not need to consider the issue of passenger flow, and the lifting speed is slower, ensuring safety. The lifting speed is generally between 0.3 to 0.4m/s, and running smoothly.
The gantry elevator is used in the door legs of large gantry cranes to transport workers and maintenance components inside the gantry crane
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 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 requirement for the shaft is that it should not be plastered, which is beneficial for reducing noise, but there should be no protruding foreign objects.

Project scope.Passengers wearing long skirts and strapping sandals when riding on the escalator should try to stand slightly in the middle of the escalator to prevent shoes and clothing from being drawn into the escalator and causing danger, and to prevent skirts or pants from getting stuck.
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, it means that the traction machine should be refueled. If not refueled, the elevator will not operate well for a long time, leading to the burning of the elevator traction machine and motor. After the elevator has been running for a long time, the oil should be replaced in a timely manner to keep the traction machine clean and in good condition.

Mine elevators are used for transporting personnel and goods in mines. Special elevators are designed for special environmental conditions, such as explosion-proof, anti-corrosion, and heat-resistant elevators
