Can cause fraying or cracking on just one edge of the belt.
The appearance of red dust (rouge) on the belt or governor rope suggests internal wire oxidation and friction, a major concern for belt integrity.
Foreign objects in the hoistway or on sheaves can "score" the belt as it travels. otis gen2 scratch
Oil or chemical spills can soften the polyurethane, making it more prone to physical damage and slipping. Monitoring and Maintenance Solutions
The Otis Gen2 elevator series replaced traditional steel ropes with flat, polyurethane-coated steel belts (CSBs). While these belts are designed for a , they are susceptible to surface "scratches" and internal degradation that require rigorous monitoring. Understanding these wear patterns—whether minor surface abrasions or critical structural failures—is essential for building safety and maintenance. Types of Belt Wear and Scratches Can cause fraying or cracking on just one edge of the belt
Unexpected damage or scratching is rarely "random" and often points to underlying mechanical issues.
If the outer cover begins to peel away (separate) from the inner carcass, complete failure may be imminent. Causes of Abnormal Wear Oil or chemical spills can soften the polyurethane,
Scratches on an Otis Gen2 belt can range from cosmetic blemishes to "scrap" conditions that demand immediate replacement.
Excessively tightened bolts can cause belts to "pucker," leading to uneven and premature wear.
If a scratch is deep enough to expose the internal steel wires or cords, the belt is compromised and must be replaced.
