High feverHousThe seat elevator person sits on a chair driven by an electric motor,High feverVilla Home Elevator Cost, 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, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally, it is cut off
High fever.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, 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.
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,High feverHydraulic flipper manufacturer, 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.
.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 the button on the chair handle causes the power drive device at the bottom of the chair to drive the person chair up and down along the guide rail of the staircase railing
2. Different types of civil engineering traction elevators, screw elevators, and hydraulic elevators have different requirements for civil engineering. Common traction elevators require a certain amount of hoistway space, which can be made of concrete, steel structure hoistways, and glass curtain walls to create sightseeing elevators; The depth of the pit should be at least 50cm or more; Additionally, there are certain requirements for the height of the top floor.
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.
The shaft for updating the old elevator: The measurement of the shaft for the old elevator is the same as the shaft that has just been constructed. When the old elevator is not yet in use, try to obtain relevant data outside the shaft, such as the size of the machine room, floor height, and net size of the door opening. There are two situations when the old elevator is not yet in use: a. When the old elevator can start: in this case, the elevator technician must cooperate in measuring the shaft! And be sure to pay attention to safety! The elevator technician opens the hall door on the first floor and initiates maintenance operations to drive the car above the second floor. The measurement personnel open the floor door on the first floor to measure the pit data, paying attention to recording the pit size and the wall structure of the first floor, such as whether the hall door is centered, whether there are brackets, the spacing between ring beams, and the position of embedded parts. Then,High feverVertical obstacle free lifting platform, the measuring personnel and elevator technicians take the elevator to the top floor. After measuring the machine room, the measuring personnel, with the cooperation of the technicians, go up to the car roof and start the elevator at a maintenance speed. When the car roof is slightly lower than the sill of the second floor hall door, the parking lot stops. During this process, the measuring personnel observe and measure the full travel of the shaft from the top floor, mainly the height of the floor, while recording the measurement (safety must be paid attention to, and special attention should be paid to moving parts such as counterweights and wire ropes).

investment.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.
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.
Slide elevators are installed inside buildings and are often used parallel to buildings and sidewalks
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.
Welcome calls .Aircraft weighing tens or hundreds of tons in the elevator hangar are vertically lifted onto the airport runway
The call button on each floor is no longer working, and the call 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.
High fever.The braking system of the elevator is usually closed, 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, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally, it is cut off
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.
