Technical Specifications for 8×19W Elevator Steel Wire Rope
The 8x19W is a high-quality wire rope specifically engineered to meet the comprehensive demands of the modern elevator industry. Its eight-strand design provides an optimal, broad surface for interaction with the traction sheave, which effectively reduces wear on both the rope and sheave grooves, contributing to a longer system life and a quieter, smoother ride.
The Warrington (W) strand construction, with its alternating pattern of thick and thin outer wires, provides a well-balanced combination of fatigue resistance (from bending) and abrasion resistance, making it an exceptionally reliable and versatile choice for various elevator duties.

This balanced performance profile makes the 8x19W a dependable workhorse, suitable for a wide array of installations. We offer two core configurations:
8x19W+FC Elevator Steel Wire Rope
This is the classic and most widely used configuration for passenger elevators. The resilient fiber core provides excellent vibration damping for a comfortable and quiet ride, making it the ideal choice for residential and commercial buildings, hotels, and hospitals where passenger experience is a top priority. The core also serves as a vital source of lubrication, ensuring the rope remains supple throughout its service life.
8x19W+IWR Elevator Steel Wire Rope
This configuration is engineered for high-performance and heavy-duty scenarios. The solid steel core provides superior breaking strength and, crucially, excellent dimensional stability with minimal constructional stretch. This makes it the essential choice for high-rise buildings where floor-leveling accuracy is critical, as well as for high-capacity freight elevators, car lifts, and other systems subjected to heavy loads and intense usage.
