What emergency calls can be made in the elevator? When an elevator has an emergency, under what circumstances can a quality or safety complaint be made when the elevator has injured or trapped people? When the elevator frequently closes doors, traps people, uneven floors, rushes to the top, squats on the bottom, elevator drivers or maintenance personnel do not have a job certificate, the driver often leaves the job, there is no inspection certificate in the car or the certificate expires, the elevator has abnormal noise or noise, abnormal Vibration or jitter, abnormal burnt smell in the car, too fast or too slow elevator, untimely maintenance, no communication or reporting device in the elevator car, etc., quality or safety complaints can be made.Wellhead elevator maintenance manufacturer
The vertical deviation of the plunger of the energy-consuming buffer should be small , the installation of the buffer should be firm and reliable, and the relative height difference should not exceed mm. End station protection device. The limit switch should act before the buffer action; the position of the forced deceleration switch is randomly determined by the manufacturer; the limit switch action distance generally does not exceed mm. Layer selector. The layer selector should be sensitive and reliable. Control cabinet. The control cabinet and electrical components should be clean and dust-free; the fuse selection should meet the requirements of the drawing, and other wires should not be used to replace the fuse; the contactor should have no abnormal noise, and the wiring should not be loose; the markings of various components and terminals should be clear; Various switches and buttons have flexible actions and good contact; various displays are normal and clear, and various components are fully identified. The control cabinet is installed firmly.In daily life, many people often operate in violation of regulations when using elevators: repeatedly pressing the door button, opening the elevator door overtime, etc., transporting decoration garbage, throwing debris, or hitting the elevator when carrying heavy objects such as furniture or building materials, or forcing it when overloaded. Squeeze in, press all the floor buttons... In fact, these are dangerous "red light running" behaviors. The technical staff of the Municipal Special Inspection Office reminded everyone that actions such as picking doors are very dangerous actions, which will cause the elevator to stop suddenly, malfunction, and cause personal injury, which are actions that cannot be done. Smoking, jumping and other behaviors in the elevator car, behaviors that violate elevator safety rules, are prone to safety hazards. In addition, there are electric vehicles or bicycles that enter the elevator car or hit the elevator door, which is also a certain hazard.
When deciding to install a home elevator in the home, safety must first be considered. Although there are many brands selling home elevators, different manufacturers have different technologies. Consumers also need to understand the actual production situation of each manufacturer and choose some safer and more reliable manufacturers.Regular manufacturers have very strict requirements on the various parts of home elevators, and have a complete production process that can guarantee the quality of home elevators. Before the actual purchase, many consumers will also take a good home elevator to run relatively smoothly, and there is no sense of frustration when stopping.Operating expenses
When using home elevators, you also need to consider specific costs. Compared with villas, elevators and commercial elevators, the costs of home elevators are relatively low. From the perspective of energy saving, consumers can choose well-known household elevator brands with better energy-saving performance.The later repair and maintenance costs of elevators introduced by well-known elevator manufacturers are relatively low, and there will be basically no failures during operation. Consumers must not be confused by some advertisements on the Internet. They must take the home elevator in person to experience the actual effect.The above is an introduction to the advantages of home elevators. Consumers also need to consider these two aspects when buying. Huzhou Fuji Elevator Co.,Ltd. has rich product varieties. We can satisfy diverse requirements from various users.

As a kind of consumable, the domestic demand for home elevators is not small. How much does it cost to install a home elevator? Regarding the specific home elevator price, you can check some data on the home elevator installation cost table. For people with different needs, the cost of installing and choosing home elevators is not small.Below we will give you an introduction to the cost of home elevators in the form of question and answer.Question: I want to buy a home elevator. What are the costs for purchasing the entire elevator?Answer: Hello, sir/madam. The cost of buying an elevator for a private family includes elevator equipment fee, elevator civil construction fee, elevator installation fee, elevator maintenance feeQuestion: How much is the equipment cost of the home elevators you sell?Answer: The quality of home elevators is different. There are three grades: high, medium, and low. Different grades have different prices. Domestic elevators of different grades have many differences in drive systems, materials, craftsmanship, performance, comfort, environmental protection, durability of components, and sense of quality. You can choose the one that suits your home according to your own economic strength.
Q: What is the civil construction fee for home elevators?Answer: The civil construction costs of home elevators mainly include the costs of shaft construction and pit excavation. The amount of this cost is directly related to the type of elevator drive and whether the product comes with an integrated shaft. Take hydraulic type and traction type for example. Usually it is necessary to build a shaft and dig a bottom pit. Now the integrated shaft can reduce the cost of digging the shaft, but if there is no one, you need to dig it. . There are also imported screw-type elevators, which are quite advanced in technology and have their own shafts without digging.Q: What kind of home elevators are there?Answer: There are 3 types of elevators for you to choose hydraulic home elevators, traction machine-room-less villa elevators, traction strong drive non-counterweight elevators, and these elevators are not divided by drive, but are divided according to the characteristics of each elevator. It’s easy to remember its advantages when you hear it.Question: I heard that the elevator has hydraulic traction screw villa elevatorAnswer: We sell all three types of elevators. The hydraulic traction screw is divided according to the drive of the elevator, which can also be said to be divided according to the structure. The 5 elevators just introduced to you all include them. The screw elevator is slower than the others, and the later maintenance may be more hydraulic.If you have any other questions about home elevators,please contact Huzhou Fuji Elevator Co.,Ltd., or visit https://www.fujiliftchina.com/

Most of the time the service station will provide the platform, switches, emergency brakes and safety locks. If they do not, you will need to install these yourself. The system that you install will be linked to the safety railing on the exterior of the elevator and you should check this regularly. Make sure that the safety system is working correctly as if there is a fault with it the elevator could fall. If you are not confident in your ability to install the elevator lift yourself you may want to hire a professional Fuji elevator lift technician to install it for you.
It is important that you keep your elevator operator's license up to date. In the UK there are strict regulations regarding operators and they must be authorised by the local council before they can work. Failure to do this will mean that you will not be permitted to operate lifts and if you are caught doing so it can result in heavy penalty. The only exception to this rule is when a malfunction occurs that cannot be fixed and the operator has been approved by the council to work.To make sure that your automated elevator service remains on the market and to ensure that customers have easy access to all of your lifts, it is a good idea to install a Fuji lift inspection tool kit. You can either get this as a free service or an annual maintenance package. This will help to ensure that your elevators are working properly and will allow the council to monitor their work. These inspection kits are usually small and can be carried around with ease. Once installed you will be able to carry out a comprehensive inspection of your lifts every six months, but of course, this will depend upon how frequently you use your elevator.
- Each home elevator should be equipped with a main power switch to cut off the elevator. The position of the switch should be easily and quickly accessible from the entrance of the machine room.

As a home elevator as a means of transportation, safety is of course the first consideration for community owners. Traction type home elevators are often mentioned in the detailed introduction of other types of elevator cars that the galvanized steel wire ropes are broken. Then will the galvanized steel wire ropes of traction villa elevators break?Everyone usually sees and rides in residential buildings, office buildings, and skyscrapers that are all traction passenger elevators. The traction home elevator is actually a miniature version of the traction passenger elevator. Because the speed of home elevators is relatively slow, The load capacity is small, the aspect ratio is improved, the safety factor is higher, and it is listed as a national inspection-free product.Equipped with safety components for traction home elevatorsFirst of all, let's talk about whether the galvanized steel wire rope of traction home elevator will break and there is a risk. In theory, no matter how strong the rope is, there is a possibility that it will break. In essence, since the invention of the traction elevator, there has been no immediate safety accident caused by the broken galvanized steel wire rope.Each of the galvanized steel wire ropes used in traction home elevators can independently bear the net weight of the elevator car. The three galvanized steel wire ropes arranged in the least parallel planes are not equipped to better prevent the galvanized steel wire rope from breaking, but only for better lifting. Traction sliding friction force to avoid the sheave deviation. So everyone think about whether three galvanized steel wire ropes will break together in theory? If there is a broken elevator car, it will report a common failure to stop the elevator, but there are at least two galvanized steel wire ropes that are sufficient to load the elevator car. Will the elevator car fall?
However, when the sliding friction of the galvanized steel wire rope is not enough, the sheave deviation may occur. The effect of the elevator speed limiter and safety gear in the safety equipment of the traction home elevator is to better avoid the flutter caused by the sheave deviation. When the operating speed exceeds the rated speed by 20%, the safety gear will lock the slide rails, which is similar to a bicycle brake. Therefore, when the elevator car is just created and invented, the manufacturer will intentionally break it at the exhibition. Galvanized steel wire rope to prove the safety of traction of the elevator car.I think the term "galvanized steel wire rope will break" is really sensational. So what is the reason why everyone hears the elevator car of a high-rise building burst? Everyone can go through the roots and understand the ancient times. The elevator car that has an accident is nothing more than an overdue service or a loss of equipment maintenance. The safety components are not working due to two reasons. The elevator car and the balance weight are used to traction the elevator car. The basic principle of equalization, and this type of equalization is unlikely to be completely equal all the time. Failure of the safety components will likely lead to rapid slipping, but it is by no means that the galvanized steel wire rope breaks.This reminds home elevator customers to also pay attention to equipment maintenance. After all, they are mechanical parts, which must be checked for regular maintenance and repaired if they are returned. Do not pay attention to maintenance, which kind of home elevator is not safe!In addition to the flutter maintenance function of the elevator speed limiter and safety gear, the traction home elevator is also equipped with protection switches, travel switches, limit power switches, overweight protection equipment, safety light curtain maintenance, oil pressure buffers, etc. Sexual maintenance function, detailed floor plan.For the characteristics of the enclosed application of Fuji home elevators in the natural environment, it is generally equipped with power failure emergency protection equipment and elevator car open contact information as standard. Therefore, home elevators are more complete than public elevator cars in terms of safety equipment.Read more: https://www.fujiliftchina.com/product/home-elevator/
A normal traction elevator is a real elevator recognized by both the European standard and the national standard. Traction means traction. The traction elevator relies on the counterweight to pull the car back and forth, while the motor only produces a little force, similar to Principle of moving pulley. More than ten years ago, the permanent magnet synchronous main engine was invented and the machine room-less elevator was created. Now the machine-room-less elevator products are becoming more and more mature. Now low-rise buildings and homes basically use machine-room-less traction elevators if they want to install guest elevators. Mechanical structure drawing of machine roomless traction elevator:Advantages of traction elevator:?High safety. There is a car, which brings passengers a sense of security. Various safety components and multiple safety measures fully protect the safety of passengers.?Quiet and stable Traction drive is relatively quiet. The permanent magnet synchronous main engine does not have a reduction box, and there will be no mechanical sound of gear friction. As long as the installation and debugging are in place, it runs very smoothly. The speed of the motor is completely adjusted by the frequency conversion variable voltage VVVF, which can call out a perfect running speed curve.?Long service life Because the counterweight is used to balance the car, the movable pulley structure makes the service life of the elevator more than twice as long as other platforms.?The energy-saving and environmentally friendly permanent magnet synchronous main engine does not need to add and replace the oil regularly, so there is no possibility of oil leakage. The motor power is relatively small, only more than 1 kilowatt, which is very power-saving. Installing a traction elevator in a family can generate up to 20 yuan in electricity a month.?Price economy. Since the permanent magnet synchronous main engine is the current development trend of the elevator industry, major manufacturers are developing and producing traction elevators. At present, it has caused overcapacity and oversupply. Therefore, the price is a bit more affordable than hydraulic (but also It depends on the brand, the price of elevators of different brands varies greatly)Disadvantages of traction elevator:?The requirements for civil construction should be high. If the top floor of the customer's house is too low (less than 2600), it cannot be installed, and the depth of the foundation pit should be more than 250 mm.?Occupying a large space size (56% of the shaft utilization), providing a car occupies a certain amount of space, in addition to adding a counterweight, so 2 rails are added, so that it takes up a little more space than other platform elevators.?Complex installation Because the structure of the normal traction elevator is complicated, there are many control parts, driving parts, and safety parts, so more complicated installation technology and more experience are required.Read more here: https://www.fujiliftchina.com/product/home-elevator/

Hoistway location and space: The hoistway location space determines the elevator and door opening size. It is a good plan to install an elevator in the middle of the stairs.
(1). The middle of the stairs, the corners, and the external hanging are all possible. It is better not to block the passage in the middle.
(2). Use the door opening width to reverse the hoistway width, and use the top floor height to reverse the car height.
(3). The recommended load capacity is 3-4 people, 225-320KG, and the inner size of the car is 0.8-1.0 square meters. The relative load capacity of the area can be larger than that of the passenger elevator to increase comfort. Determination of style and style: Mainly consider the hoistway environment and personal preferences, and secondly consider the cost and difficulty.
(1). Airtight hoistway is equipped with airtight car, sightseeing hoistway is equipped with sightseeing car, which can be used for sightseeing on three sides or partly. It is recommended to install glass windows on the door.
(2). The car has various shapes. Rectangular, circular, and combined types are all available, and automatic folding doors with transparent materials are recommended
(3). Because there are many elevator parts, it is not easy to use transparent glass for family sightseeing elevators, which is the function and safety measures of domestic elevators. The users of home elevators lack elevator professional knowledge, and there are no dedicated elevator service personnel, and the safety cannot be reduced. It is best to configure them in accordance with passenger elevator standards.
(1). There are generally two ways to open the door. Automatic door and manual door. Automatic and manual doors must have an electromechanical interlock function to prevent the door from being opened when the door is opened and the elevator is not present.
(2). Domestic elevators on the second floor abroad have no hoistway and no door. But there must be safety measures to prevent shear collisions.
(3). Some villa elevators are designed with manual swing doors. The car has no door. Then a light curtain door must be installed to prevent the danger of friction, collision, and extrusion.
(4). It is recommended to connect the local telephone extension in the car to prevent the alarm for help when the trouble is trapped.
(5). Increase self-rescue measures and procedures when trapped. Passengers are not allowed to help themselves in the passenger elevators, and families are different, and copying them completely may cause long-term sleepiness.
(6). Standard configuration with power-off emergency leveling function and device. However, this function should be used in abnormal conditions such as overhaul and maintenance. Car plane layout and appearance: In order to save area, a reasonable layout is required. The engineering machinery editing and analysis adopts double-leaf deflection automatic doors, and the plan of focusing on the side is more rational. The hoistway width of 1200mm corresponds to the car's width of 850mm and the door opening width of 700mm.
1. Quantity selection
The choice of the number of Passenger Elevators mainly depends on the estimation of the passenger flow. The accurate analysis of the passenger flow of different buildings requires a large amount of statistical data, which is currently not available. Different designers often make estimates based on their own experience. The following are some experience values ??for reference only.
(1) Residential: 70 tower dwellings/unit; panel dwelling 100 units/unit; 3 elevators should be installed on more than 20 floors.
(2) Hotel: The number of passenger elevators is based on 100 rooms/set, and the number of service elevators is considered as 1/3 of the passenger elevators.
(3) Office building: according to the construction area of ??5000m2/set or according to the number of office workers 250 people/set.
2. Speed choice
Increasing the speed of the elevator can shorten the average travel time and improve the service level of the elevator, which depends on the service level required by the building and the height of the building itself. The increase in speed may greatly increase the cost of elevators.
For office buildings, low-speed elevators below 2m/s should be considered for buildings below 75m. For buildings between 75m and 150m, the elevator speed may increase by 0.5m/s for every 20m increase in height. For residential buildings, generally only 1m/s elevators are considered for multi-storey houses, 1.5m/s for towers or slabs with 10 to 16 floors, and 2m/s for elevators with 16 to 22 floors.
3. Choice of deadweight
Overloading is forbidden by the elevator, and the load capacity of the elevator is the maximum weight transported by the elevator at a time. The choice of this parameter directly restricts the maximum service capacity of the elevator. For high-rise residences and apartments, it should be more than 1000kg; for office buildings, it should be more than 1350kg; for large shopping malls, it should be more than 1600kg.
4. Selection parameters
Elevator design should clarify the following parameters: elevator civil engineering requirements, such as layout, machine room location, hall door size, car decoration, etc.; elevator usage description, including landing, travel, service floor, etc.; number of elevators; elevator rated parameters , Such as rated speed, load, operating system, control system, leveling accuracy; elevator power requirements, lighting requirements, communication requirements, etc.
When the Sightseeing Elevators are arranged side by side, there should not be more than 4 elevators. This is because the stopping time of the elevators generally does not exceed 8s, and passengers may not have time to enter the elevators. If the elevator is installed in zones, it can be divided into one area on the 15th floor, and 600 × 1800 fire doors are installed every 11m from the hoistway of the non-stop floor. If the depth of the elevator pit exceeds 2.5m, an iron climbing ladder shall be installed, and an overhaul socket and well safety lighting (36V) shall be installed at the bottom of the pit. For fire-fighting elevators, the power supply requires dual-circuit power supply, and is equipped with a control system for forced landing on the first floor in a fire-fighting state. In high-end buildings, sometimes it is necessary to make some special decorations for the elevator car and hall station, and the reserved size should be considered when designing
With the rapid development of my country's economy, row upon row of high-rise buildings, the development of elevators has become an inevitable trend and the focus of attention. The elevator is not only an important equipment in the production process, but also a transportation equipment that people frequently ride and enjoy.
1. Development of environmental protection technology.
The world today has a very clear understanding of the relationship between survival and development: you cannot survive without being environmentally friendly, and there is no development without survival. The green concept has been deeply rooted in the hearts of the people around the world, and the green concept is the general trend of elevator development. Some experts predict that "whoever launches green products first and seizes the market will control the initiative in market competition." The main development trends are as follows: continuous improvement of product design, production of environmentally friendly elevators with low energy consumption, low noise, no oil leakage, no water leakage, no electromagnetic interference, and no oil pollution from the hoistway guide rail. Passenger elevator traction adopts nylon synthetic fiber traction rope, steel belt and other non-lubricating traction methods. Elevator decoration will use environmental pollution-free materials. The energy feedback technology of the elevator's no-load rise and full load down motor regenerative power generation. There is no need to install scaffolding when installing elevators. Elevator parts have no impact on the environment during production and use and the materials can be recycled.
2. Development of energy-saving technology.
- The drive system uses a permanent magnet synchronous gearless traction machine. Compared with the traditional worm gear and worm drive traction machine, the permanent magnet synchronous gearless traction machine has the following advantages:
(1) The permanent magnet synchronous gearless traction machine is directly driven, without worm gear or worm drive. The permanent magnet synchronous motor does not have the very space-consuming stator coil required by the asynchronous motor, and the main material for making the permanent magnet synchronous motor is high energy The density of neodymium iron boron with high remanence induction and high coercivity generally has an air gap magnetic density of more than 0.75T, so it can be small in size and light in weight.
(2) High transmission efficiency. Due to the direct drive of permanent magnet synchronous motors, the transmission efficiency can be increased by 20% to 30%.
(3) Permanent magnet synchronous gearless traction machine because there is no noise generated by the bearing when an asynchronous motor is running at high speed and there is no noise generated by the worm gear contact transmission, so the noise of the whole machine can be reduced by 5?10db (A ).
(4) Low energy consumption. From the working principle of the permanent magnet synchronous motor, it can be known that the excitation is realized by the permanent magnet, and the stator does not need to provide additional excitation current, so the power factor of the motor can reach very high. At the same time, there is no current through the rotor of the permanent magnet synchronous motor, and there is no rotor loss problem. Generally, the loss is reduced by 45%?60% compared with asynchronous motors. Since there is no low-efficiency and high-energy consumption worm gear pair, energy consumption is further reduced.
(5) Permanent magnet synchronous gearless traction machine does not have the problem of tooth profile wear and does not need to replace the lubricating oil regularly, so it has a long service life and basically does not require maintenance. In the near future, if the cost of producing permanent magnet synchronous motors can be solved as soon as possible, permanent magnet synchronous gearless traction machines will replace the traction machine composed of worm gear and asynchronous motors. Of course, superconducting force drag technology and magnetic levitation drive technology will also be applied to elevators in the future.
The rated power of the elevator traction motor is designed according to the maximum output power of the traction motor when the car is fully loaded or unloaded. When the car and counterweight are in the same working condition, the traction motor only needs to overcome the static pressure friction on the traction sheave in theory, and its output power does not reach full load and there is still margin under the premise that the motor power remains unchanged. , When the car and counterweight are in the same working condition, the elevator running speed can be relatively increased according to the number of passengers. Compared with the traditional elevator running at rated speed, the use of variable speed technology can appropriately increase the elevator speed (the original elevator speed can be increased by about 1.6 times). This relatively reduces the waiting and boarding time of passengers, which is also a contribution to energy conservation and environmental protection.
