If a scratch is deep enough to expose the internal steel wires or cords, the belt is compromised and must be replaced.
The appearance of red dust (rouge) on the belt or governor rope suggests internal wire oxidation and friction, a major concern for belt integrity. otis gen2 scratch
Polyurethane is the protective barrier for internal steel wires. Minor scratches often result from foreign objects or builder debris trapped near the sheaves during installation. If a scratch is deep enough to expose
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 Minor scratches often result from foreign objects or
Excessively tightened bolts can cause belts to "pucker," leading to uneven and premature wear.
Unexpected damage or scratching is rarely "random" and often points to underlying mechanical issues.
