Elevators can be seen everywhere in shopping malls. They bring convenience to people’s lives. The types of elevators include escalators and vertical lifts. A friend asked the editor whether it is good to use screw elevators at home, then Today I want to share with you whether screw elevators are good or not and what are the disadvantages of screw elevators.

Is the screw elevator good?

1. The screw elevator is currently the most floor-saving household elevator in China. The screw elevator has no wire ropes and no car walls, so it requires only a small installation space. It only takes 900X900 mm to install a screw-type home elevator.

2. The imported screw elevator operates at a slower speed, so the mechanical structure is safer, so there is no need for buffers, speed limiters and other devices, so there is no need to dig the foundation pit of the elevator, which only requires 50 Millimeters are enough, and there is no need to make special load-bearing ring beams. Only one wall is needed to complete the installation. Especially the height of the top floor can reach more than 2000 mm.

3. The screw elevator can easily realize door opening at right angles, through opening the door, and opening the door on three sides without affecting the stability of the elevator. The structure of the screw type home elevator is relatively simple, so it is not prone to failure. The structure is flexible, so later maintenance and repairs can be eliminated.

4. The screw elevator has high safety. There is always something supporting the screw elevator below. Even if the power is suddenly lost, the descent speed will be very slow. If necessary, you only need to lock the screw. This can prevent the elevator from free-falling.

What are the disadvantages of screw elevators

1. Screw elevators have a certain amount of mechanical noise because the motor follows the platform, so the mechanical noise of the motor will inevitably affect the householder. However, Most users can tolerate this sound. If they are very quiet users, they may not be suitable for screw elevators.

2. The running speed of the screw elevator will be slower. Due to the limitations of the mechanical structure, the running speed of the screw home elevator cannot be too fast. It can only reach about 0.15-0.25 meters per second at most. , compared with the running speed of 0.4 per second of the traction type, there is half the gap. If you are a user who pays more attention to efficiency, it is not recommended to use the screw elevator.

3. Due to the limitation of the screw, the lifting height of the elevator is also limited. Therefore, screw elevators are very suitable for places such as villas and small businesses that do not have high lifting height requirements. .
