Sulab PV40 Elevator Steel Belt 40mm Traction Belt

The Schindler PV40 is a Poly-V traction steel belt (STM) specifically designed for Schindler elevators, offering superior performance and reliability.

The "40" in PV40 indicates a width of 40 millimeters. With a minimum initial breaking force of 56kN, this can be verified by checking the model marking and minimum initial breaking force marking on the wedge sleeve.

Constructed with fine steel wires (steel core) wrapped in composite polymer materials (typically polyurethane), this belt offers:

• Excellent wear resistance and tensile strength
• Stable performance in extreme temperatures (-30℃ to 80℃)

• High Safety: Flat structure design increases traction sheave contact area for greater friction and slip prevention. Eliminates derailment risks associated with traditional rope grooves. Multiple belts provide load capacity far exceeding operational requirements.
• Energy Efficiency: 20% lighter than steel ropes with 10%+ energy savings. Higher flexibility allows smaller traction sheave diameters for compact, efficient transmission systems.
• Riding Comfort: Minimized noise and vibration through polyurethane flexibility and compact drive host design.
• Low Maintenance: No lubrication required. Polyurethane wrapping prevents elongation, breakage, and fraying. Reduced replacement frequency and simplified maintenance procedures.
