What are the advantages and disadvantages of using steel belt and traditional wire rope traction in elevators?

1. Advantages of steel belt elevator compared with wire rope elevator:

1. Compared with the steel wire rope widely used in elevator industry, the life of composite steel belt is longer, which is 2-3 times that of traditional steel wire rope.

2. Lighter weight, about 20% lighter than the traditional steel wire rope.

3, more durable, each composite steel wire rope contains about 588/ 1 176 high-tension steel wires, which is more than the traditional steel wire rope.

4. The security is stronger. Each composite steel belt can bear the tensile force of 3200kg/6400kg, and each elevator has at least three composite steel belts, and the safety factor for passengers is at least 12.

Second, the shortcomings of steel belt elevator compared with wire rope elevator:

Due to the limitation of noise, vibration and use, the calorific value of elevator is relatively large, and its various electronic components have poor high temperature resistance. Moreover, the temperature of the permanent magnet synchronous gearless traction machine currently used should not be too high, otherwise it is easy to cause "loss of magnetism".

Extended data:

From the point of view of home, the vertical shaft space, the height of the top floor and the depth of the pit are often limited by various aspects, and the small size of the steel belt main machine will become a very important advantage.

The height of the steel belt guide wheel is generally 100 mm in diameter, and the minimum diameter of the steel wire rope guide wheel is 200mm, with a difference of 100mm, and then the height of the steel belt main machine is generally more than 200 mm, and the height of the steel wire rope main machine is generally close to 400mm, here it is also more than 100mm, and the difference between the two is close to 30.

So generally speaking, it is best to install elevators with steel belts at home, and the height of the top floor is less than 3000 mm. If the height of the top floor can reach more than 3000 mm, steel wire rope can be used.
