Elevator Traction Belt<\/strong>, also known as Elevator Steel Belt<\/strong>, is used under different names by various elevator brands. KONE<\/strong>\u00a0and TK Elevator<\/strong>\u00a0commonly refer to it as Elevator Suspension Belt<\/strong>, while Otis<\/strong>\u00a0typically uses the terms Elevator Flat Steel Belt<\/strong>\u00a0or Elevator Gen2 Belt<\/strong>.<\/p>

If you work in the elevator industry, you know that traction technology is changing. The traditional round steel wire ropes are steadily being replaced by Elevator Traction Composite Steel Belts<\/strong> (often simply called elevator steel belts or elevator traction steel belts).<\/p>

But what exactly goes into these belts? How do you calculate the required length? What is the difference between an Otis belt and a Schindler belt? In this comprehensive guide, we will leave no stone unturned. We will cover everything from product structure and brand specifications to calculation formulas and packaging logistics.<\/p>

Part 1: Product Overview<\/strong><\/h2>

An elevator steel belt<\/strong> is a flat, composite component used in traction-driven elevators. It connects the elevator car to the counterweight and transmits power from the traction machine to achieve smooth vertical lifting.<\/p>\n\n

Simply put, a steel belt is the upgraded replacement for a wire rope. It is essentially multiple steel wire ropes coated with a layer of rubber or polyurethane (PU), giving it its signature flat shape.<\/p><\/div>

The Market Reality:<\/strong> While major elevator brands like Otis and Schindler use these belts, the belts themselves are manufactured by top-tier component brands like ContiTech (Germany) and Brugg (Switzerland). In today’s market, many buyers opt for high-quality aftermarket belts. These aftermarket solutions provide the exact same performance as the OEM parts but at a highly competitive price.<\/p>

Part 2: Product Structure & Material Characteristics<\/strong><\/strong><\/h2>

A steel belt consists of two main parts: a flat polyurethane (PU) outer layer and a high-strength galvanized steel wire core.<\/p>

The outer PU jacket tightly wraps the steel cores. This flat design increases the contact area with the traction sheave, which boosts friction and ensures stable operation.<\/p>
