Traction Steel Belts vs. Steel Wire Ropes

At Fuji Elevator Company, we are committed to advancing vertical travel with innovative and reliable solutions. One of the most exciting developments in elevator technology is the shift from traditional steel wire ropes to modern traction steel belts. In this blog, we’ll explore the differences between these two traction components, their respective advantages and challenges, and the future trends shaping their use in elevators.

### **Understanding Traction Steel Belts**

Traction steel belts are a recent advancement in elevator technology. Unlike traditional steel wire ropes, these belts consist of numerous thin steel wires encased in a composite material. This design offers several benefits:

- **Enhanced Durability:** Traction steel belts typically last 2 to 3 times longer than conventional steel wire ropes.
- **Lightweight:** They are approximately 20% lighter, which contributes to a more efficient elevator system and reduces the size of the main engine.
- **Smooth Operation:** The design of steel belts provides a quieter and more comfortable ride, with minimal noise and vibration.

However, steel belts also come with some considerations:
- **Installation and Maintenance:** They require precise installation and regular cleaning to maintain optimal performance. Debris or foreign matter can lead to noise and vibrations.
- **Damage Detection:** Internal damage or broken wires in steel belts are not visible and require specialized equipment for detection.
- **Suitability for High-Rise Elevators:** Currently, steel belts are less suitable for high-rise and high-speed elevators due to vibration and durability issues.

### **The Time-Tested Reliability of Steel Wire Ropes**

For over a century, steel wire ropes have been the cornerstone of elevator traction systems. Their benefits include:

- **Proven Technology:** Steel wire ropes have a long history of reliable performance, with well-understood maintenance and operational requirements.
- **Visibility of Wear:** Wear and tear on steel wire ropes can be easily observed, facilitating straightforward maintenance.
- **Cost-Effective:** They offer a lower economic cost compared to steel belts and meet national standards for various building types.

Nonetheless, steel wire ropes do have some drawbacks:
- **Maintenance Needs:** Regular lubrication and monitoring for wear and tear are necessary.
- **Space Requirements:** Steel wire ropes may require a larger main engine and shaft space compared to steel belts.

### **Determining Durability and Maintenance Needs**

Both traction steel belts and steel wire ropes require diligent maintenance to ensure longevity. For steel belts, factors such as installation quality, environmental conditions, and frequency of use play crucial roles in determining their lifespan. Steel belts should be inspected for physical damage, broken strands, rust, and performance issues to determine when they need to be replaced.

### **Future Trends in Elevator Technology**

**Low-Speed Elevators:** Traction steel belts are increasingly favored for low-speed and residential elevators due to their space-saving and maintenance advantages.

**High-Speed Elevators:** Steel belts are still in the experimental phase for high-speed and high-rise elevators. Ongoing research aims to address challenges such as vibration and environmental sensitivity.

**Economic Considerations:** For projects where cost is a primary concern, steel wire ropes remain a practical choice. However, for applications emphasizing comfort and smooth operation, steel belts offer a superior experience.

### **Conclusion**
