Elevator Cast Iron Sheave: Durability and Performance

An elevator cast iron sheave is a critical component in traction elevator systems, responsible for guiding and supporting the elevator ropes or cables. Made from high-quality cast iron, these sheaves (also called pulleys) ensure smooth, efficient movement of the elevator car and counterweight by reducing friction and wear on the cables.

Key Features and Benefits

• Durability: Cast iron’s high strength and wear resistance make it ideal for long-term use, even under heavy loads.

• Precision Engineering: The grooved design ensures proper cable alignment, minimizing slippage and enhancing safety.

• Noise Reduction: Cast iron’s natural damping properties help reduce operational noise compared to other materials.

• Heat Resistance: Withstands high friction-induced temperatures without warping or losing structural integrity.

Applications

Primarily used in traction elevators, cast iron sheaves are installed in machine rooms or overhead structures. They are commonly found in mid-to-high-rise buildings where reliability and longevity are essential.

Maintenance Considerations

Regular inspections for wear, lubrication, and alignment checks are necessary to prevent cable damage and ensure optimal performance.

FAQ
1. Are the elevator wire ropes durable?
The elevator wire rope has special provisions and requirements. Configuration is not only for wire rope and rated load, but also considered the size of the traction, as a result, the tensile strength of wire rope is greater than the weight of the lift. The safety factor is equipped with more than four wire rope. So it won’t break at the same time.
2. Is it dangerous for power failure suddenly during the elevator running?
If it occurs, the elevator will automatically stop due to the electrical and mechanical safety device. In case of power failure,elevator brakes will automatically taken. In addition, the power supply departments such as planned outage, prior notice are also operating.
3. Will us be hurt when it closed suddenly?
In the closing process, if people touch the hall door, the door of elevator will automatically restart without any danger. With anti clamping switch, once the gate touched, this switching action make the elevator unable to be closed and even reopened. In addition, closing force is also available here.
4. How the elevator running?
Elevators are operated with a counterweight wire rope through the (tractor) traction drive, making ups and downs on the guide rail.
5. Is the escalator installation complicated?
We believe the functions of an escalator are not necessarily proportional to the operation complexity. Therefore, escalators designed by us apply an integrated structure, so that the equipment is more precise and more efficient and allows easier and more convenient commissioning.
6. Do you have any cerifications?
Yes, we do with ISO9001 / CCC / CE Certificates for u.
