1, saving construction area

Screw drive should be an elevator product that saves building area in China at present. Without counterweight, steel wire rope and car wall, a screw-type domestic elevator can be installed with only 900X900 mm installation space.

2, the civil requirements are low

Screw-type domestic elevator is relatively safe due to the advantages of mechanical structure, so there is no need to dig elevator foundation pit. As long as the height of a decoration surface is 50 mm, there is no need to make a special load-bearing ring beam, and it can be installed as long as there is a wall, especially the height of the top floor, which can be1500 mm.

3. The structure is flexible, stable and reliable

Spiral household elevator can easily realize right-angle door opening, straight-through door opening and three-sided door opening, without affecting the stability of the elevator and increasing the shaft area. The spiral domestic elevator has simple structure, is not easy to break down, and has few wearing parts, which saves the trouble of customer's later maintenance.

4. It has high security.

Imported screw-type household elevators are said to never fall down. Judging from its main structure, there has always been something under the screw elevator. Even if the power is suddenly lost, the descent speed is very slow. If necessary, just lock the screw to prevent the elevator from falling freely.

Screw elevator is an elevator in which the plunger of a straight-top elevator is processed into a rectangular thread, and then a big nut with a thrust bearing is installed on the top of the oil cylinder, and then the motor drives the nut to rotate through a reducer (or belt) to make the screw lift the car up or down. Simply put, there is a huge screw under the elevator, and the car rises and falls with the rotation of the screw. The safety is high, because in fact, something has been resisting below, that is, losing power and falling freely, and the screw will also drive the motor to do more negative work, which will be very slow, so you will definitely not fall down when you take this elevator. Just lock the screw to prevent the free fall from falling.
