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 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, 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
.The gantry elevator is used in the door legs of large gantry cranes to transport workers and maintenance components inside the gantry crane
The braking system of the elevator is usually closed, which means it is in the braking state when there is no power,Schiedam Price of hydraulic flipper,Schiedam Household small elevator prices, 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
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.

The new technology of frequency regulation and voltage regulation (VVVF), abbreviated as Variable Voltage Variable Frequency in English, is based on the principles of electrical engineering. The speed and torque of the motor are directly proportional to the frequency and voltage amplitude of the AC power supply, achieving accurate speed regulation and control of the motor. This speed regulation technology ensures smooth elevator operation, accurate leveling, and flexibility.

where.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, the load capacity of home elevators does not exceed 400kg, 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, professional home elevators, villa home elevators, home elevator manufacturers, and small home elevators. They are 20 year old brands with advantages in price and guaranteed quality. Considering the limited installation space, lack of dedicated hoistways, and small lifting height, they pursue simplicity and miniaturization in design, and the existence of computer rooms is not necessary. Long term promotion of a domestic elevator manufacturer, a 20 year old brand with competitive prices and guaranteed quality!
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.
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.
OK or not?.When encountering abnormal elevator operation, you can call the repair hotline to consult with the maintenance personnel or inform the service center to handle it. Do not take unauthorized measures to avoid causing greater harm to the elevator or even causing casualties.
When the normal power supply is cut off, the lighting inside the non fire elevator has no power, while there is still lighting inside the fire elevator.
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, the elevator hall door may not be tightly closed, and after several consecutive doors are opened and closed, while also repairing any faults and hidden dangers found.
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.
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.
Schiedam .Household elevators must be regularly maintained to confirm their safety and whether they can continue to operate
