What is the reason for the large price gap of domestic elevators

2021-11-17

With the increasing popularity of domestic elevators, many owners will install a villa elevator to upgrade the villa level when decorating the villa, and it is also convenient to go up and down the stairs. But domestic elevators are not common electrical appliances, which are unfamiliar to many people. Among them, the price of domestic elevators is a matter of concern to everyone. So why is there such a big gap between domestic elevators? (1) Size: under the same conditions, if the transmission mode of the domestic elevator is the same, the larger the elevator shaft size, the higher the landing station, and the higher the cost. (2) Elevator brand: no matter which product brand is different, the price of small household elevator is different. If it is an imported brand elevator, the price will be higher than that of domestic brand elevator. And in the same brand, different configurations will lead to different prices. (3) Transmission mode: There are three transmission modes for family elevators. I believe those who have known about them are familiar with hydraulic transmission, traction transmission and screw transmission. The former two are common among domestic domestic domestic elevators, while the latter are more common in foreign domestic elevators, and the price of domestic elevators will vary with different driving modes. (4) Elevator hoistway: It is also necessary to pay attention to whether there is an elevator hoistway when quoting the domestic elevator. If there is a civil elevator hoistway, it is not necessary to consider the frame-integrated product. If there is no reservation, it depends on what materials are used in the hoistway. Generally, it is aluminum alloy or steel structure. If the hoistway is made of all-aluminum alloy, the price will be higher, and the material of the hoistway made of steel structure is also lower. But aluminum alloy is better than steel structure in terms of beauty.

With the development of the times and the improvement of people's living water products, the requirements for the quality of life at home are also constantly improving. Many owners often pay attention to the price of the domestic villa elevator when decorating the villa elevator. So what determines the price of the domestic elevator in Chongqing? How do we compare shopping? 1、 Equipment costs: We say that domestic elevators and cars are similar in different grades, such as high, medium and low, and the corresponding prices will also vary. The difference of grade is reflected in the driving system, profile material, manufacturing process, safety performance, comfort, beauty and many other aspects of the domestic elevator. The price of the general domestic elevator is about 120000-150000, and that of the high-end elevator is usually more than 200000. So you can choose according to your own economic ability! 2、 Hoistway cost: The domestic elevator is generally composed of two parts: the elevator itself is the elevator car we see, and the elevator hoistway is a space for the elevator car to run. The cost of civil hoistway and sightseeing hoistway is different. The civil hoistway needs you to build the hoistway space in the early stage. This part of elevator company is not responsible for the construction of sightseeing domestic elevator, The elevator car and hoistway are integrated with glass on all sides. The lighting and beauty are better, and the cost of digging and constructing hoistway is saved. 3、 Installation cost: The installation cost is related to the size of the hoistway, the installation location, and the driving mode. The smaller the size, the more the number of floors, the more difficult the installation is. The elevator installed outdoors has more influence factors than indoors. The driving mode is different because of the different complexity of their structures. The more complicated the installation is, the more troublesome the natural cost will increase. 4、 Maintenance cost: As a large household equipment, the service life of the domestic elevator is more than 20 years, so the maintenance after installation is also an important link, and the annual maintenance is also an expense, so when purchasing the domestic elevator, you should consult whether the later maintenance will be timely and how often? How much is the price?
