EdSelf propellSlide elevators are installed inside buildings and are often used parallel to buildings and sidewalks
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.
Ed.Reduce the overall noise of the machine. Due to the absence of noise from bearings during high-speed operation of an asynchronous motor and the absence of noise from worm gear transmission, the overall noise can be reduced by 5-10db (A) Low energy consumption. From the working principle of permanent magnet synchronous motors, it can be seen that their excitation is achieved by permanent magnets, and there is no need for the stator to provide additional excitation current. Therefore, the power factor of elevators can reach a very high level. At the same time, the rotor of the motor has no current and there is no problem of electronic loss. Generally it reduces consumption by 45% -60% compared to asynchronous motors. Due to the lack of low efficiency and high energy consumption worm gear transmission pairs, energy consumption is further reduced.
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
.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.
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, 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.
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.
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?
The basic content of escalator shaft measurement is to measure the lifting height. The same as measuring the height of a straight ladder, strictly speaking the lifting height of a ladder is the vertical distance between the finished ground at the upper and lower support beams. When using the suspension line method to measure, attention should be paid to whether there is a drop between the positioning point of the line drop and the decoration surface of the lower support beam of the ladder.
The seat elevator person sits on a chair driven by an electric motor,EdAluminum alloy high-altitude lifting platform, 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
Good reputation.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.

How much is it.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
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, 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 wearing high heels, be careful not to step on the gap between the pedals, as not wearing shoes is more likely to be pinched by the toothed plate.
Ed.Will the elevator quickly fall during a power outage& mdash;& mdash; Some movies and TV dramas often mislead the public into thinking that if the elevator loses its power,EdSmall stage elevator, it will lose control and engage in falling movements.
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
Aircraft weighing tens or hundreds of tons in the elevator hangar are vertically lifted onto the airport runway
