19x7 Non Rotating Steel Wire Rope 4mm-10mm Lifting Winch Tower Crane Wire Rope

19x7 galvanized steel wire rope is a high-strength steel wire rope with a multi-strand structure, manufactured by twisting 19 steel wire strands around the central strand, with each strand containing 7 steel wires. This "19 strands x 7 wires" structure provides excellent flexibility and anti-torsion performance, maintaining stable operation under complex working conditions. The galvanized surface layer offers superior corrosion resistance, effectively protecting against harsh environmental conditions such as moisture, acid, and alkali, thereby extending service life. It is widely used in fields requiring high strength and weather resistance, including lifting and hoisting, port operations, cableway transportation, and bridge construction.

• Multi-strand twisting structure: The layered twisting design of 19 strands x 7 wires provides superior overall flexibility, adapting to frequent bending and twisting work scenarios. Compared to ordinary single-strand steel wire ropes, it is less prone to wire breakage and loose strands.
• Outstanding anti-torsion ability: The outer and central strands utilize reverse twisting technology to counteract twisting torque under stress, effectively preventing rotation during lifting and traction operations while improving operational stability.
• Steel wire strength matching: High-strength carbon steel wire is selected for twisting, with single wire tensile strength exceeding 1770MPa, balancing corrosion resistance and load-bearing capacity without breaking under heavy load conditions.
• Adapt to complex working conditions: Due to its flexibility and anti-torsion characteristics, it is particularly suitable for scenarios requiring frequent reversing and lifting, such as cableway transportation, tower cranes, and port loading/unloading equipment.
• High safety redundancy: Even if a small number of single wires break in the multi-strand structure, the overall force can still be evenly dispersed, preventing instant failure and providing additional operational safety protection.

Common uses of 19x7 structure, 4.0-18mm diameter galvanized steel wire rope:

19x7 galvanized steel wire rope is primarily used in three categories of scenarios due to its strong flexibility, torsion resistance, and corrosion resistance:

• Lifting and hoisting: Main and auxiliary lifting ropes for tower cranes, gantry cranes, and other equipment
• Transportation: Cableway transportation, traction ropes for port loading and unloading machinery
• Outdoor engineering: Load bearing operations in harsh environments such as bridge construction, mine hoisting, and ocean platform fixation

Our steel wire rope meets international production standards and has obtained multiple certifications including SGS, CE, and ISO.
