New YorkAluminThe elevator suddenly descends to the bottom floor and resumes normal operation: After the elevator is powered off and reconnected, the leveling reference position needs to be re determined.
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?
New York.There is a dedicated fire telephone in the fire elevator car.
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 braking system of the elevator is usually closed, which means it is in the braking state when there is no power, 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
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 elevator suddenly descends to the bottom floor and resumes normal operation: After the elevator is powered off and reconnected, the leveling reference position needs to be re determined.
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.
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, voltage regulation, and speed regulation, and adopts light curtain protection. Safety components such as safety gear, speed limiter, and buffer must be manufactured.
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.
Superior quality.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, the elevator will stop. Professional quality assurance for home elevator manufacturers. Discount activities are underway, and new and old customers are welcome to come for consultation
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,New YorkHousehold sightseeing elevator, but their feet move with the steps. Especially when carrying a lot of packages while taking the elevator, 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.
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.
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, 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.
Inspection items.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.
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.
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, when riding on the escalator it is more likely to fall on the escalator due to the inability to hold the handrail properly. So, we must stand firmly and support it well, and do not lean against the skirt board on the side of the escalator.
New York.The braking system of the elevator is usually closed,New YorkHome elevator villa self built house, 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.

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.
Slide elevators are installed inside buildings and are often used parallel to buildings and sidewalks
