OTIS Gen2 Elevator Traction Steel Belt AAA79176M | PU Coated Flat Steel Belt For Lift Replacement 30mm Width Flat Belt

Core Function: Traction Drive
Connects the traction machine, car, and counterweight, transmitting power through friction with the traction sheave to achieve elevator lifting and lowering.
Utilizes a multi-strand fine steel wire (588/1176 strands) + polyurethane (PU) wrapping structure, with a tensile strength of up to 32kN and a single strand capable of bearing 3200kg.
Each elevator is equipped with 3-6 strands as standard, with a safety factor of **≥12**, far exceeding traditional steel wire ropes.

2. Structural and Technical Advantages

Flat and Ultra-thin Design: 30mm wide and 3mm thick, adaptable to smaller diameter traction sheaves, enabling machine room-less/small machine room designs.

Quiet and Low Noise: PU material reduces iron-iron friction, resulting in 40% lower operating noise than steel wire ropes.

Lubrication-Free: PU surface coating requires no oiling, eliminating oil pollution, environmentally friendly, and easy to maintain.

Extra-Long Lifespan: Wear-resistant and corrosion-resistant, with a service life 2-3 times that of traditional steel wire ropes.

Lightweight: 20% lighter than steel wire ropes, reducing the load on the main unit and saving approximately 15-20% on electricity.

Safety Monitoring Features

Compatible with Otis steel belt monitoring system: Real-time detection of wear, cracks, and elongation when powered on.

Equipped with belt breakage protection switch: Immediately stops the elevator and issues a warning in case of abnormality, preventing the risk of falls.

4. Applicable Scenarios
Otis Gen2, GeN2-MR, LVC, Skyrise, and other machine-room-less/small machine-room elevators.

Alternative Models: AAA717AM2, AAA717W1, AAA717AJ2, AAA79176A/B, etc.

Elevator Steel Belt – Frequently Asked Questions

Q1: Can elevator steel belts with the same width and thickness be interchangeable?

Not necessarily. Belts with identical dimensions may differ in steel cord construction, coating properties, mechanical performance, and approved applications. The original equipment specifications must be verified.

Q2: What can cause cracks in elevator steel belt coatings?

Possible causes include material aging, repeated bending, environmental exposure, or abnormal mechanical conditions. The actual cause cannot be determined from surface appearance alone.

Q3: Does visible coating damage mean an elevator steel belt must be replaced?

Visible damage requires professional inspection. Replacement decisions should follow the elevator and belt manufacturers inspection criteria and applicable safety requirements.

Q4: What specifications are needed to identify a replacement elevator steel belt?

Check the original part number, belt dimensions, construction specifications, elevator model, and required length. Photos of belt markings can help identify the product.
