Selection and replacement of elevator steel belts

Why do more people choose steel belts instead of elevator wire ropes?

1. It is safer. Each composite steel wire rope contains about 588-1176 high-voltage steel wires. Each composite steel belt can withstand 3200kg-6400kg force. Each elevator has at least 3 composite steel belts.

2. Stronger corrosion resistance. Steel is easily oxidized and rusted in air and water, while the corrosion rate of zinc in the atmosphere is only 1/15 of steel. Galvanized steel strips are protected from corrosion by high-quality zinc coating.

3. Long service life. Compared with the steel wire ropes widely used in elevators, the composite steel belt has a longer life, and its service life is 2-3 times that of the traditional steel wire rope. And the weight is 80% of the weight of the steel wire rope, and it also has the advantages of low noise…

How should elevator steel belts be replaced? What are the important considerations?

1. The replacement of elevator steel belts should be carried out according to the regulations of the elevator manufacturer, or at least the requirements for strength, quality and design equivalence of the steel belts should be met.

2. Elevator steel belts that have been installed and used on other elevators must not be used again.

3. The elevator steel belt should be replaced as a whole set. Replacement of a single belt can easily cause accidents.

4. Elevator steel belts in the same group should be new elevator steel belts of the same material, grade, structure and size provided by the same manufacturer.
