8x19S+8x7+PP - 16 elevator steel rope

Introduction to 8×19S + 8×7 + FC Semi - Steel Core Wire Rope

Structural Features

Strand Composition

"8×19S" indicates that there are 8 strands, with each strand composed of 19 wires, adopting the Seale construction. In this structure, the outer wires are relatively thick, which endows good abrasion resistance. "8×7" means there are another 8 strands, each containing 7 wires.

Core Material

"FC" represents the fiber core, usually made of natural fibers or synthetic fibers. It's not a semi - steel core. Common types include natural fiber cores like sisal or synthetic fiber cores such as polypropylene (PP). The fiber core provides the wire rope with certain flexibility, lubricity, and anti - extrusion ability.

Performance Characteristics

High Strength and Abrasion Resistance

The 8×19S - structured strands contribute to the overall high strength of the wire rope. The thick outer wires exhibit excellent abrasion resistance when in contact with pulleys and other components, enabling it to adapt to working scenarios with frequent friction.

Good Flexibility

The 8×7 - structured strands and the presence of the fiber core endow the wire rope with good flexibility while maintaining strength. It can adapt flexibly during bending and winding operations.

Shock Absorption and Buffering

The fiber core can act as an internal buffer and shock absorber when the wire rope is subjected to external impacts, reducing vibrations caused by impact loads.

Lubrication and Rust Prevention

The fiber core can store lubricating oil, continuously providing lubrication between the internal wires and strands of the wire rope. This not only reduces friction but also helps prevent rust, thus extending the service life.

Application Fields

Elevator Industry

It is often used as the hoisting wire rope for elevators. Its flexibility and strength ensure the smooth and safe operation of elevators.

Lifting and Hoisting Operations

In general lifting equipment at ports, construction sites, etc., it can meet the requirements for the strength and flexibility of wire ropes when lifting goods.

Mechanical Transmission

It can be used in some mechanical equipment that requires power transmission or traction, such as winches and elevators.

If it is indeed a wire rope with the structure of 8×19S + 8×7 + PP, generally, PP can be regarded as the fiber core material. Similar to the above - mentioned performance characteristics, it has good chemical stability and certain strength, further enhancing the comprehensive performance of the wire rope.
