● core: fiber core
● strand: warrington-seale
● steel wire rope for suspended platform
The 4-strand construction, combined with a specific lay length design, effectively counteracts internal rotational torque, preventing platform tilting caused by rope rotation. The WS (Warrington-Seale) configuration features alternating wire diameters in the outer layer; this not only increases the contact area with sheaves or drums but also enhances overall crush resistance and surface wear resistance, thereby extending service life under demanding operating conditions.
The fiber core (typically made of natural or synthetic fibers, such as polypropylene/PP) imparts superior flexibility and shock-absorbing (cushioning) properties to the rope while reducing its overall weight, making it ideal for suspended platform lifting systems that involve frequent bending and movement over drums.
Wire ropes for suspended platforms typically undergo a full galvanization process, resulting in a dry, smooth surface that effectively resists corrosion caused by rain and humidity in outdoor environments.
