What Are the Specifications of Elevator Wire Ropes?
In elevator and hoisting systems, the elevator wire rope is a vital component responsible for power transmission and load bearing.
It directly affects the elevator’s safety, smoothness, and service life.
Different working environments and load requirements demand various wire rope types and specifications.
So, what kinds of wire ropes are there, and how should you choose the right one?
Here, the technical team from A-FLY Elevator & Escalator Parts Supplier provides a detailed explanation.
1. Basic Structure and Meaning of Elevator Wire Ropes
An elevator wire rope is composed of several thin steel wires twisted into strands, which are then wound around a central core.
Common designations include 6×19S+FC, 8×19S+FC, and 6×37+IWRC.
Their meanings are as follows:
6×19S: Six strands, each containing approximately 19 steel wires.
FC (Fibre Core): A fiber core that provides flexibility and good bending performance.
IWRC (Independent Wire Rope Core): A steel core that offers greater load capacity and higher resistance to compression.
A-FLY supplies multiple types of elevator wire ropes, including both fiber-core and steel-core models, compatible with various traction machine systems.
2. Common Wire Rope Specifications
Different specifications are suitable for different traction systems and loads. Common models include:
6×19S+FC / 6×19W+IWRC – General-purpose design, flexible and durable, ideal for mid- and low-rise elevators.
6×37+IWRC – Offers higher flexibility, suitable for high-speed elevators or heavy-duty traction systems.
8×19S+FC / 8×19W+IWRC – Multi-strand structure with superior load-bearing and smoother operation.
Diameters: 10mm, 11mm, 12mm, 13mm, 16mm — chosen based on elevator traction machine size and load capacity.
High-strength galvanized wire ropes provide excellent corrosion resistance for outdoor or humid environments.
A-FLY’s elevator wire rope series is made of high-carbon steel, processed through precise drawing and galvanizing to ensure high strength, long life, and quiet operation.
3. Performance Requirements for Elevator Wire Ropes
Unlike general lifting ropes, elevator-specific wire ropes must meet stricter standards:
High flexibility: Prevents wire breakage under frequent bending.
Strong wear resistance: Maintains stable friction during long-term operation.
Low elongation: Ensures smooth car movement and accurate leveling.
High fatigue resistance: Adapts to frequent start–stop operation.
A-FLY’s elevator wire ropes are certified under ISO and EN standards, guaranteeing reliable performance even under heavy-duty conditions.
4. Application Scenarios for Different Wire Rope Specifications
6×19S+FC / 6×19W+IWRC: Commonly used in residential and freight elevators; stable and cost-effective.
6×37+IWRC: Ideal for medium to high-speed passenger or panoramic elevators; low noise, high fatigue resistance.
8×19S+FC / 8×19W+IWRC: Perfect for large shopping mall or high-rise building elevators; superior traction and anti-torsion strength.
10mm / 12mm / 13mm / 16mm ropes: Diameter selection depends on traction sheave size and ratio — a key factor during design.
A-FLY offers full-size elevator wire rope solutions for residential, passenger, freight, observation elevators, and escalator traction systems.
5. How to Tell When a Wire Rope Needs Replacement
Since elevator ropes endure continuous tension and friction, regular inspection is essential. Replace immediately if you notice:
Visible broken wires or burrs;
Rope diameter reduced by more than 10%;
Rust or lack of lubrication;
Slippage or noticeable vibration of the car.
A-FLY ensures fast delivery for replacement parts, helping maintenance teams minimize downtime.
