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,NejackHousehold elevator, and the motor overheats. To prevent burning out, the motor cools down and automatically resumes operation.

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.

Nejack.Maintenance of elevator hall doors and car doors. Elevator malfunctions usually occur on the elevator hall and car doors, so that the elevator will not make unpleasant noises during operation and the opening of the door. Pay attention to the inspection of the safety contact plate or light curtain type contact plate switch wire of the elevator, as the frequency of opening and closing the door in the elevator is high, which can cause damage to the switch wire. This requires maintenance personnel to inspect it every time they work, and replace it in advance to avoid users having doubts about the quality of the elevator product due to door issues.

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.

.As elevator people, let's talk about elevator and elevator safety knowledge: The elevators we currently use include box type passenger elevators escalators, and dedicated cargo elevators. Dedicated cargo elevators are installed due to special needs, and we don't use many of them. Now, let's take a look at the safety knowledge of box type passenger elevators and escalators: When we take escalators, Be sure to follow the safety instructions when riding on the elevator. Do not crowd or play around, hold onto the elevator firmly, fasten your shoelaces, and avoid getting them caught up.

If there is a reserved shaft in the villa residential area,NejackCustomized household small elevator, the appropriate car model can be selected by comparing the width and depth of the elevator car based on the size, width, you can first choose the model of the elevator and create a new shaft based on the required reserved size space for different models.

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, we must stand firmly and support it well, and to prevent skirts or pants from getting stuck.

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, 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,NejackSelf walking aluminum alloy lifting platform, like braking to stop.

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.

b. When the old elevator cannot start: due to the inability to enter the shaft, limited data can only be obtained from outside the shaft to determine whether it is non-standard (if there is a high platform in the machine room, the plane size of the shaft can be measured in the machine room, but it is not accurate enough) for elevator quotation negotiation reference. In this case, the signing of the contract should state that the shaft rectification and costs are the responsibility of the user. For uncertain shaft structures and dimensions, users should be reminded to provide them to the elevator after the old elevator or notify the elevator to take measurements before the new elevator is put into operation.

Nejack.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, and running smoothly.

Household elevators have gradually become an essential vertical transportation tool for modern single family, duplex, multi story, villa and other residential buildings, practical and convenient, and even a beautiful scenery in the home.
