WIRE ROPE
Elevator wire rope is a key component for ensuring safe operation. Selection must consider factors such as elevator type, speed, and structure to ensure compliance with relevant standards and actual requirements. Elevator wire rope types include: traction wire rope, speed governor wire rope, and compensating wire rope.
For low speed elevators (lifting speed ≤ 2.0 m/s), 8×19S-NFC is recommended. The rope core is made of natural sisal, which offers excellent oil storage, support, and corrosion resistance.
For medium and high speed elevators (lifting speed > 2.0 m/s), the custom-made 8×19S-NFC or 8×19S-CSC (a steel and fiber composite rope core) can be used.
For high speed elevators (lifting speed > 3.0 m/s), the 8×19S-IWRC or 8×19S-CSC is recommended.
For super high speed elevators (lifting speed > 5.0 m/s), the 9×19S-IWRC or 9×19S-CSC is recommended.
---------------------
For low-rise elevators (travelling height ≤ 80 m), the 8×19S-NFC is recommended.
For mid-rise elevators (travelling height ≤ 150 m), the 8×19S-NFC or 8×19S-CSC is recommended.
For high-rise elevators (travelling height ≤ 200 m), the 8×19S-IWRC or 8×19S-CSC is recommended.
For super high-rise elevators (travelling height > 200 m), the 8×19S-IWRC or 8×19S-CSC is recommended. 9×19S-IWRC or 9×19S-CSC
Preferred wire ropes are 6×19S-SFC or 8×19S-SFC. These ropes use a synthetic fiber core (PP). This structure offers excellent flexibility, support, and impact cushioning. The minimum diameter should be no less than 6mm, ensuring strength and durability while minimizing the risk of breakage due to wear.
Preferred wire ropes are 6×29F-SFC and 6×37M-SFC. These offer excellent flexibility and fatigue resistance. Common single-strength strengths are 1570MPa, 1770MPa (European and American elevators), or 1620MPa (Japanese and Korean elevators). These are primarily used in medium- and high-speed elevators, replacing compensating chains to reduce noise and improve the ride experience.
