With the development of the home elevator industry, there are many types of home elevators. At present, there are screw elevators, hydraulic elevators, traction elevators, etc., and many of them are screw elevators. Recently, many customers often consult small-sized screw elevators. How many units are suitable for screw elevators?

Which type of floor is the screw home elevator suitable for?

The screw home elevator is most suitable for the two-storey and three-storey duplex, attic, leap, loft, and villas. Because the screw elevator has the characteristics of light weight and no bottom pit, the screw home elevator is most suitable for the duplex building, the attic, the leaps, the loft, the cascading villas, etc., which have the problem of bearing the bottom slab and can not dig the pit. Heavy weight of the home elevator can not meet the conditions of the depth of the bottom of the elevator. The screw home elevator can be said to be the only choice for this type of apartment. And this type of apartment generally does not exceed 3 floors.

Why can't a screw elevator with more than three layers be made? There are two kinds of screw elevators for household use, which are divided into nut rotation type (mother moving rod does not move) and screw rotation type (rod moving mother does not move), nut rotation type noise is much higher than screw rotation type. The screw rotary screw elevator can only achieve 3 layers at most, the floor is higher, the screw weight is increased, the motor can't be driven; the nut rotary screw elevator can achieve more than three layers, even four-layer and five-layer screw elevators. The effect of the experience is very poor. The reason is that no matter how high the screw is, the middle can not be fixed. It can only be fixed at both ends. The middle is suspended and the floor is higher. The longer the length of the screw, the greater the amplitude of the vibration swing, the more vibration and vibration of the car, the less comfortable it is, the louder the noise, and the more difficult it is to bear. Therefore, we do not advocate the use of more than 3 layers of household screw elevators.
