Normally, elevator wire ropes feature parallel strand construction for reducing incidence of abrasion compared with ropes with cross laid construction. Meanwhile, they have a high fatigue bending life and less wear to running sheaves.

Construction:

Depending on the intended needs, two different core types are available: fiber core (FC) and independent wire rope core (IWRC).

Fiber core, made of natural or synthetic fibers, is widely used in ropes and makes elevator ropes easier to adjust up to the relevant groove shape. Meanwhile, fiber core provides excellent resistance against contact pressure and long-term support for elevator wire ropes.

Independent wire rope core effectively increases the metallic cross-section of elevator wire ropes and reduce tensile stress in individual wires. Meanwhile, steel cores low the elongation of elevator wire ropes under same loads compared with fiber core.

Normally, an elevator wire rope is composed of six, eight or nine strands with FC or IWRC

Main construction: 8*19S+FC, 8*19S+8*7+pp, 8*19S+8*7+1*19, 6×19S+NF, 8×19S+NF
