1. The requirements of civil engineering should be very high. If the top floor of the customer's house is too low, it cannot be installed. The depth of the foundation pit should exceed 300 mm.
2: The traction elevator must have a counterweight, so two guide rails need to be added, which will take up more space than the hydraulic elevator, usually 150 mm higher than the hydraulic elevator. In the case of relatively narrow space, there is no way to install it (less than the inner diameter of the hoistway only 1400X1100). In addition to the space occupied by the counterweight, the minimum size of the mainframe base is also limited. 3: The quality of the traction elevator is mixed. The mainstream of the market is traction elevators. Everyone is doing traction elevators. There are too many brands, and some manufacturers will fight price wars, compress and reduce costs, and finally can only sell subpackaged products. Another point is the safety of traction elevators. If the host and control system are poor, a brake failure may occur and the operation may be out of control. So choose the brand elevator, safe.
The advantages of spiral villa home elevator
1. Save building area
Screw drive should be the most cost-effective household elevator product in China. There is no counterweight, no wire rope, no car wall, so the minimum installation space only needs 900X900 mm to install the spiral home elevator.
2. Low civil engineering requirements
Spiral home elevators run slowly. Due to the safety of the mechanical structure, there is no need for buffers, speed limiters, etc., so there is no need to excavate the elevator foundation pit. Since the height of a decorative surface can be (50 mm), there is no need to specialize To make a load-bearing ring beam, as long as there is a wall installation, especially the height of the top floor, the minimum can be 2000 mm.
3. Flexible structure, stable and reliable
The spiral home elevator can easily directly open the door, open the door, and open the door on three sides, without affecting the stability of the elevator, and without increasing the hoistway area. The spiral home elevator has a simple structure, is not prone to failure, and has fewer wearing parts. Customers can save money in the future. In terms of maintenance and maintenance, in terms of safety performance, it is said that the spiral home elevator will never leave the ladder, and the main structure is safe and reliable. But in the end, how high the security factor is, after all, it has been less than a few years in the market in China.
Disadvantages of spiral home elevator
1: There is a certain amount of mechanical noise
Since the motor follows the platform, it is difficult to avoid the mechanical noise of the motor and transmit it to the user's ears. However, many users can accept this sound. If it is very quiet, users with OCD may not be able to adapt to the screw jack.
2: Running speed is slow
Due to the limitation of the mechanical structure, the spiral home elevator can not run too fast, and can only do 0.15-0.25 m/s at most, which is half of the gap compared with the 0.4 m/s per meter. second. If you want to focus on efficiency, users won't like it too much.
3: Comfort is lower than traction and hydraulic pressure.
The platform and the screws are directly connected to each other, and the mechanical vibration is transmitted to the platform. Although it's not obvious, it doesn't feel as soft and smooth as the traction or hydraulic type, and it feels a bit hard.
