When Should Elevator Steel Belts Be Replaced?
With the advancement of elevator technology, the Elevator Steel Belt has gradually become the core component of the new generation traction system. It uses high-strength steel wires as the inner core, covered with a wear-resistant polyurethane layer on the outside. This design combines flexibility with durability, making it safer and quieter than traditional wire ropes. However, steel belts are not “maintenance-free” components. Over time, they will inevitably experience aging or wear during long-term operation.
If not replaced in time, steel belts may pose safety risks to the elevator. The following situations indicate that your elevator steel belt has reached the point where replacement is necessary:
1. Noticeable decline in ride comfort
If passengers feel vibrations, inaccurate leveling, or unsmooth operation, this may result from increased friction or imbalance in belt tension. Many property managers focus only on the control system while overlooking the role of traction belts. In fact, these “discomforts” are often signs of steel belt wear.
2. Visible aging on the surface
The polyurethane outer layer is the protective barrier of the belt. Cracks, scratches, bulges, or discoloration on the surface indicate material aging. Even if it does not immediately affect use, it means durability is reduced and further deterioration is likely.
3. Internal wire damage
The core load-bearing capacity of the elevator steel belt comes from the internal steel wires. If some wires break due to fatigue or corrosion, the overall safety performance of the belt is compromised. Since such damage usually occurs inside and cannot be easily observed with the naked eye, professional inspections are necessary.
4. Long-term overload operation
In elevators with heavy passenger flow and frequent starts and stops, the traction force and friction endured by the steel belt are much higher than in normal conditions. Under such high-intensity use, the service life of the belt is significantly shortened. If the elevator operates under heavy load for extended periods, the belt should be replaced earlier instead of waiting until severe wear occurs.
5. Exceeding its design lifespan
The typical service life of an elevator steel belt is 10–15 years. Once it exceeds its lifespan, it should be replaced proactively, even if it appears intact. Both the polyurethane layer and internal steel wires degrade over time, leading to accumulated potential risks.
Why timely replacement matters
Many elevator accidents are not caused by control systems but by overlooked wear in traction components. Once a steel belt fails, it may cause operational interruptions or even safety incidents. Timely replacement not only eliminates risks but also ensures a smooth and quiet riding experience.
