19 x K7

Groxx | 19×7 Compacted Steel Wire Rope
High-Performance Rotation-Resistant Wire Rope
The Groxx 19×7 Compacted Steel Wire Rope is an industrial-grade, non-rotating wire rope engineered for crane hoist lines, main and auxiliary winches, and deep vertical lifting applications. Designed with a rotation-resistant strand layout, this rope resists twisting under load while offering exceptional pulley wear characteristics and higher breaking loads across all diameter sizes.

Core Performance Features

Rotation-Resistant Engineering: Constructed to counteract rotational torque under load, keeping lifted materials stable and preventing line spin.

Versatile Lay Options: Available in both ordinary lay (regular lay) and Lang’s lay configurations to suit varying winch drum and pulley setups.

Galvanized Protective Finish: Hot-dip galvanized coating provides long-lasting resistance against rust, salt spray, and harsh weather exposure.

Pulley & Sheave Optimized: Smooth strand geometry maximizes contact surface area with pulleys, reducing sheave wear and extending rope service life.

Optional Plastic Impregnation: Available with custom internal plastic impregnation and specialized lubrications to achieve higher breaking strength and superior internal abrasion resistance.

Key Applications

Tower & Mobile Cranes: Primary or secondary hoist lines operating over multi-reeved sheaves.

Industrial Winches: Smooth spooling on multilayer drums due to its outer strand stability.

Piling & Foundation Rigging: High-tension vertical extraction under severe dynamic loads.

Deck Cranes & Marine Hoists: Corrosion-protected galvanized construction ideal for salt-water and offshore environments.
