Otis Traction Steel Belt AAA717AM2 – Installation, Maintenance & Replacement Guide

The AAA717AM2 is the super-aromatic polyamide-coated steel traction belt that turns every Otis Gen2® and Gen2® Life machine into a whisper-quiet, oil-free elevator system. Only 3 mm thick yet rated for 2,300 kg tensile load, this flat belt replaces traditional ropes, eliminates machine-room sheave wear and cuts energy consumption by up to 25 %. When internal corrosion or coating cracks appear, the car can slip or the belt monitor will shut the system down. Nanjing Zhuye Elevator Parts keeps thousands of metres of genuine AAA717AM2 belt on reels in Rotterdam and Nanjing so you can restore safe traction the same week it fails. Below is an 800-word field manual that explains correct usage, on-car inspection and the replacement cycle that keeps your elevators safe, efficient and code-compliant.
1. What the AAA717AM2 does
-
12 high-carbon steel cords, 1.5 mm Ø each, encapsulated in green polyurethane
-
Polyamide top-coat reduces friction coefficient to 0.45 – no lubrication needed
-
Factory-stamped data matrix every 500 mm for full traceability
-
UL/CE certified to EN 81-20/50 and CSA B44.1 for 15-year service life
-
Compatible with Otis SSS belt monitor – detects 2 broken cords or 5 % cross-section loss
2. Tools to carry
-
AAA717AM2 belt (Nanjing Zhuye part #OT-BELT-AAA717AM2) on 100 m reel
-
Otis belt tension gauge (0–1,000 N)
-
3 mm & 4 mm Allen keys, 13 mm open-end wrench
-
UV torch and 10× magnifier
-
Laptop with Otis Diagnostic Tool (ODT)
-
Lock-out / tag-out kit
3. Installation – 45 minutes with two technicians
Safety: place the car on top-of-travel buffers, engage mechanical brake and lock-out main supply.
-
Attach 50 kg rated sling to car cross-head; raise car 300 mm to unload belts.
-
Mark old belt ends with Sharpie for length comparison.
-
Cut and remove retaining clips; pull belt out of sheave grooves.
-
Clean sheaves with IPA; polish any burrs with 800-grit paper.
-
Feed new AAA717AM2 through drive and idler sheaves; ensure data matrix faces outward for scanner readability.
-
Install new stainless clips (supplied) and torque to 25 N·m.
-
Tension to 450 N ±20 N per belt using Otis gauge; lock adjustment nuts.
-
Run 3 full-height learning trips; SSS monitor must show “Belt OK” green.
-
Record serial numbers, installation date and initial tension in CMMS.
4. Functional test – prove it to the controller
a) Static tension: 450 N ±20 N at 20 °C.
b) Belt slip test: apply 150 % rated load; slip ≤ 2 % of travel.
c) SSS monitor: resistance imbalance <5 % between cords.
d) Visual: no coating cracks >5 mm or exposed steel.
e) Log all values in ODT and export PDF for the site file.
b) Belt slip test: apply 150 % rated load; slip ≤ 2 % of travel.
c) SSS monitor: resistance imbalance <5 % between cords.
d) Visual: no coating cracks >5 mm or exposed steel.
e) Log all values in ODT and export PDF for the site file.
5. Preventive maintenance schedule
-
Monthly – visual sweep for coating cracks or black dust under car.
-
Quarterly – measure tension; adjust if deviation >30 N.
-
Annually – UV scan for internal corrosion (green coating fluoresces, rust does not).
-
Every two years – replace belt clips and re-torque to 25 N·m.
6. Replacement cycle – calendar or condition, whichever comes first
Otis specification: 15 years. Nanjing Zhuye field analytics refine this to real duty:
-
Light duty (<150 starts/day, clean office): 18 years
-
Standard duty (150–400 starts, residential): 15 years
-
Heavy duty (>400 starts, hospital, mall): 12 years
-
Coastal or chemical plant (airborne salts): 10 years – corrosion accelerates cord failure.
Replace immediately if:
-
SSS monitor shows “Belt Fault” – ≥2 broken cords detected
-
Visible steel wires or coating cracks >20 mm
-
Tension drops >50 N in one month – indicating core creep
-
Black rubber dust under machine – coating delamination
7. Eco-disposal & warranty
Return the old belt on the supplied reel; Nanjing Zhuye recovers steel and polyurethane and issues a €20 recycling credit per 100 m. Every AAA717AM2 belt ships with a 15-year manufacturer warranty against cord fatigue when installed by certified technicians.
