Otis — Gen2 Scratch Verified

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.

Oil or chemical spills can soften the polyurethane, making it more prone to physical damage and slipping. Monitoring and Maintenance Solutions otis gen2 scratch

Otis uses specialized technology to ensure scratches do not lead to catastrophic failure. Elevator Maintenance Pt. 3 - Belting & Bucket Wear Patterns

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 Excessively tightened bolts can cause belts to "pucker,"

Visible "shadows" or imprints of the steel cords on the belt surface indicate significant wear or material aging.

The appearance of red dust (rouge) on the belt or governor rope suggests internal wire oxidation and friction, a major concern for belt integrity. While these belts are designed for a ,

Can cause fraying or cracking on just one edge of the belt.

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.
