Elevator Steel Wire Rope

Elevator Wire Rope is a specialized part of the Aogang steel wire rope range, manufactured for passenger elevators, freight elevators, commercial buildings, hospitals and other traction lift systems.

Unlike general lifting rope, elevator wire rope operates under frequent start-stop cycles and repeated bending over traction sheaves. Production control therefore focuses on rope diameter, roundness, structural elongation, lubrication, breaking force and consistency between ropes installed in the same set.

Available constructions include 8×19S, 8×19W, 6×19S, 6×25Fi and 8×25Fi, with diameters from 6 mm to 25 mm. FC, IWRC and WSC cores are available. Selection must be based on the lift design, sheave groove, sheave diameter, suspension ratio, travel height, speed and original rope specification—not elevator capacity alone.

Elevator Wire Rope Core Process Highlights

Double deformation shaping process: Adopts pre-deformation + post-deformation precision processing to completely eliminate residual stress of the rope body, eliminating running jitter, strand loosening and twisting deformation.

Pre-tensioning shaping process: Overall pre-tensioning treatment before leaving the factory, effectively reducing structural elongation rate. No secondary running-in is required after new elevator installation, and the size remains stable during long-term operation. The elevator runs smoothly throughout without jitter or stagnation.

Special grease infiltration: Filled with special long-acting lubricating grease for elevators, reducing wear and noise, rust and corrosion prevention, suitable for high-frequency friction working conditions of traction wheels.

Full-item precision testing: Full inspection of rope diameter tolerance, roundness, breaking force, bending fatigue, etc. before warehousing, ensuring elevator safe operation standards.

What Information Determines Elevator Rope Selection?

Original Rope Construction

An 8×19S rope and an 8×19W rope may have the same nominal diameter, but their internal wire arrangements differ. This affects bending behavior, outer-wire contact and interaction with the traction sheave.

For replacement projects, the original construction should normally be maintained unless the lift manufacturer approves a change.

Rope Diameter and Sheave Groove

The actual rope diameter must match the traction sheave groove. A rope that is too large, too small or inconsistent with other ropes in the set can result in uneven contact and unequal load distribution.

Strength Combination

Some elevator ropes use dual-tensile wire combinations to balance external wear, internal flexibility and overall breaking force. A higher tensile strength is not automatically a better choice.

Rope Core

FC provides cushioning and lubricant retention. IWRC and WSC provide greater structural support. Changing the core may affect diameter stability, flexibility, traction and groove contact.

Elevator Wire Rope Performance Advantages

• Ultra-low structural elongation rate, factory pre-tensioning shaping, no stretching or relaxation during elevator operation, smooth throughout without jitter or stagnation.

• Equipped with special long-acting lubricating grease for elevators, stable friction coefficient, low noise and small vibration during high-frequency traction operation, better riding experience.

• Precise rope diameter, extremely small roundness, smooth and rounded rope body surface, extremely high fitting degree with traction wheel groove, uniform wear and not easy to slip out of the groove.

• Excellent bending fatigue resistance, suitable for high-frequency start-stop and reciprocating bending working conditions of elevators, long service life and longer maintenance and replacement cycle.

• Tight and stable structure, balanced force distribution, sufficient safety margin of breaking force, meeting the strict safety specifications of elevator special equipment.

FAQ

Can ordinary lifting wire rope replace elevator wire rope?

No. Elevator rope has specific requirements for diameter consistency, structural elongation, bending fatigue, lubrication and traction sheave compatibility.

Can 8×19S and 8×19W be interchanged?

Not without technical approval. The original design, sheave condition, groove profile and lift manufacturer’s requirements must be checked first.

Is higher tensile strength always better?

No. Excessively high wire strength may change bending performance and contact behavior. Use the strength combination specified by the lift manufacturer.

Can only one rope in a matched set be replaced?

Ropes in the same set should have consistent construction, diameter, length, production condition and service history. The maintenance provider should determine whether the complete set must be replaced.

Can galvanized rope be used for elevators?

Galvanized elevator wire rope may be available for specific environments, but the surface, traction performance and applicable standard must be confirmed.

What should I provide if the original specification is unavailable?

Provide a rope sample, cross-section photograph, measured diameter, number of strands, core type, traction sheave information and lift operating data.
