Width: 30 mm
Thickness: 4.5 mm
Wire Core: 12 steel cords
Breaking Strength: 42 kN
Material: Polyurethane (PU) body with steel wire tensile cords
Surface: V-groove design
Operating Temperature: -20°C to +85°C (-4°F to +185°F)

Features & Advantages

High Strength & Durability: Combines steel cords for tensile strength with PU coating for flexibility and wear resistance.
Maintenance-Free: No lubrication required, reducing environmental impact.
Compact Design: Takes less space than traditional steel ropes, enabling smaller motors and sheaves (ideal for MRL elevators).
Enhanced Ride Comfort: Quiet operation with minimal vibration and oscillation.
Corrosion Resistance: Resistant to rust, chemicals, UV rays, and moisture.
Long Service Life: TPU material offers excellent anti-aging and low-temperature performance (down to -40°C). 

Applications

Used in Schindler elevator models such as 3300, 3600, 5500, and other traction systems requiring flat belts instead of round ropes.
