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.
Alexandria.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,AlexandriaCustomized household small elevator, without worm gear or worm drive, and without the stator coil that occupies a significant amount of space required for asynchronous motors, 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.
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.

The seat elevator person sits on a chair driven by an electric motor, 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
If there is a reserved shaft in the villa residential area, the appropriate car model can be selected by comparing the width and depth of the elevator car based on the size,AlexandriaHousehold villa small elevator manufacturer, and depth of the shaft. If there is no reserved shaft, you can first choose the model of the elevator and create a new shaft based on the required reserved size space for different models.
Aircraft weighing tens or hundreds of tons in the elevator hangar are vertically lifted onto the airport runway
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, whether there are special structures on the shaft wall, the spacing between ring beams, and the position of embedded parts. Then, 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).
When wearing high heels,AlexandriaHydraulic unloading and tipping machine, 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.
Highly recommended.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
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.
The difference between home elevators and ordinary public elevators is that the focus of home elevators and ordinary public elevators is different, 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.

Professional is king.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.
Electrical components are roughly divided into screens, electrical switches for each safety circuit, etc. It is the brain of the elevator and the central nervous system of the elevator. The movement, operation, and door opening and closing of the elevator are all controlled by it, so it must be treated as a top priority in daily maintenance work. Do not short circuit the elevator circuit inside the screen during work. When the elevator door system malfunctions, someone shorts the elevator door for convenience in order to find the fault. This is very dangerous, and there are many accidents when shorting the door. Why? If a person opens the hall door and extends their head inward, the elevator happens to run up or down to this point, and the hall door is shorted the elevator cannot stop, so an accident is highly likely to occur. So in our daily maintenance work, we must not short-circuit the safety circuit. If it is necessary to short-circuit, we must identify which safety component has a problem and which safety component needs to be shorted. Moreover, after maintenance or urgent repairs are completed, we must promptly remove the short-circuit wire. Professional household elevator manufacturer, with a large quantity and excellent quality at a reasonable price. It is fire-resistant, waterproof, high-temperature resistant, sturdy and durable safe and reliable
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.
