Steel Wire Rope 19x7 (Semi-rotation resistant)
Product information
Main- and auxiliary hoist line on mobile- and truck cranes. Often used as a single point line. Large lifting heights will require a tag line to prevent excessive spinning of the load. Smaller sizes (< 3/8”) are sometimes used on overhead cranes.
NOT recommended for construction tower cranes.
Rope characteristic: Using the rope to it’s maximum fatigue life will cause the rope to deteriorate from the inside out. Sudden rope failures may be the result. For this reason we do not recommend this construction for tower cranes. There have been fatal and catastrophic accidents involving this rope construction because of undetected inner rope fatigue.

Product FAQ
What surface finish and tensile strength does this steel wire rope have?
This steel wire rope has a Bright, Galvanized and is manufactured with a tensile strength of 1770, 1960 N/mm².A bright (uncoated) finish has no corrosion protection and is therefore primarily used in dry, indoor, or controlled environments. Bright wire ropes are generally selected for cost reasons. The galvanized coating provides corrosion protection through a zinc layer, making the rope suitable for outdoor use and humid operating conditions.
Does this steel wire rope have any special design or performance features?
This steel wire rope is designed to be rotation resistant, minimizing torque and rotation under load. It is particularly suitable for lifting applications involving single-line operation or long lifting heights.
What is the construction, core type, and lay of this steel wire rope?
This steel wire rope is constructed with Multistrand strands.
It is manufactured with a steel core, offering higher structural stability, improved resistance to crushing, and reliable performance under heavy loads and multi-layer winding conditions.
It is manufactured with an ordinary right-hand lay (sZ), providing a balanced combination of flexibility, wear resistance, and stable handling. This is the most commonly used lay for general
