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.
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.
Germany.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, accurate leveling, and flexibility.
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 do not lean against the skirt board on the side of the escalator.
.Overloaded elevators do not operate: The load of elevators is limited, and if they are overweight, they will alarm and generally cannot be started. Most passengers can also voluntarily exit.
Slide elevators are installed inside buildings and are often used parallel to buildings and sidewalks
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.
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.
Drive Method&# 8217& mdash; The advantages of worm gear traction machines and permanent magnet synchronous gearless traction machines compared to worm gear traction machines are: simple and compact structure, small volume, and light weight. Due to the fact that the permanent magnet synchronous traction machine is directly driven, without worm gear or worm drive, and without the stator coil that occupies a significant amount of space required for asynchronous motors, its main material is high energy density, high residual magnetic induction, and high coercive force neodymium iron boron. Its air gap magnetic density generally reaches over 0.75T, so it can achieve small volume and light weight.
Household elevators have gradually become an essential vertical transportation tool for modern single family, duplex, multi story, villa and other residential buildings,GermanyCustomized household small elevator, practical and convenient,GermanyNew type of small elevator for household villas, and even a beautiful scenery in the home.
assets.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?
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.
The braking system of the elevator is usually closed, which means it is in the braking state when there is no power, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally it is cut off
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.
Direct labor.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.
To implement the arrangement of escalators and provide feedback, in order to determine the configuration of certain shared devices, the order of shipment, and the alignment of handrail turns during continuous arrangement.
Elevators are used to transport firefighters, passengers, and fire-fighting equipment in the event of a fire. They are used to transport frozen goods in large cold storage or refrigeration workshops. However, they need to meet the requirements of sealing the door leaves and guide rails at the moving parts. Professional household elevators, villa household elevators, and small household elevators have stable, safe, reliable, and maintenance free performance, and their technical level has reached the domestic level, Meet the advanced level of international similar products and immersion requirements
Germany.Factors to consider when choosing a household elevator: 1. Safety. Generally, brand elevators must have third-party testing, and elevators that have been inspected by professional organizations are safe, reliable, and guaranteed to be used with peace of mind. In addition, when choosing to purchase villa elevators, it is important to understand the safety components and configuration of this elevator. The essential safety equipment in the villa elevator includes a backup power supply and an emergency call outside telephone system to ensure the safety of private users on the elevator.
Home elevators are different from special products such as public spaces, 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 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.
