Elevator Wire Rope Selection – Speed, Height, and Structure
Elevator Wire Rope Selection – Speed, Height, and Structure
Selecting the correct wire rope for an elevator is not a one-size-fits-all decision. Rope performance depends directly on elevator speed, lifting height, and traction ratio. Using the wrong structure can lead to premature wear, vibration, or even safety risks.
At Boyuan Metal, we categorize elevator wire ropes into three application groups:
Low-rise / low-speed traction
- Speed: V < 2 m/s
- Storey height: H ≤ 30 m
- Recommended structures: 6×19+FC, 8×19+FC, 8×19S+NF
High-rise / medium-speed traction
- Speed: 2 m/s ≤ V < 4 m/s
- Storey height: H ≤ 100 m
- Recommended structures: 8×19+FC, 8×19S+IWRF, 8×19S+8×7+PP
Super-high-rise / high-speed traction
- Speed: V ≥ 4 m/s
- Storey height: H > 100 m
- Recommended structures: 9×19+IWRC, 9×19+IWRF, 9×19S+IWRF
For elevator speed governor ropes, synthetic fiber core (PP) is generally preferred to reduce slippage and ensure reliable governor action.
When ordering, always specify the rated speed and lifting height. This allows us to apply the correct production process — particularly for specialized structures such as 8×19S+8×7+PP, which differs from standard low-rise rope manufacturing.
Still not sure which structure fits your elevator system? Contact our engineering team with your parameters, and we will recommend the optimal solution.
What the Construction Codes Mean
In a code like 8x19S+IWRC: 8 is the number of strands, 19 the number of wires per strand, S is a Seale-type layout of wire sizes, and IWRC means an independent wire rope core - a steel core that resists crushing better than a fibre core (FC). FC ropes are more flexible; IWRC ropes are stronger and more dimensionally stable.
FC or IWRC - How to Decide
The application groups above already point the way: fibre core for low-rise, slower installations where flexibility matters, steel core for higher speeds and heights where strength and stability matter. If you are weighing the two in detail, see our guide on FC versus IWRC rope cores, or send us your elevator parameters.
Frequently Asked Questions
What does 8x19S+IWRC mean?
8 strands of 19 wires each, in a Seale-type wire layout, over an independent wire rope core. IWRC gives the rope higher strength and better crush resistance than a fibre core.
Which rope core does a speed governor need?
A synthetic fibre core (PP) is generally preferred for governor ropes - it reduces slippage and keeps the governor acting reliably, as noted in the guide above.
What do I specify when ordering?
The rated speed and the lifting height, plus the structure if your elevator design calls for one. That lets us apply the correct production process for your installation.
