Wire Rope 4VX39S

Wire Rope 4VX39S

4VX39S wire rope is a high-strength compacted strand wire rope. "4V" stands for 4 V-shaped (triangular) special-shaped strands, and "39S" means that each strand contains 39 steel wires and is twisted in the Westerly (S-shaped) method, with compaction technology to form a compact structure.

Its core features are strong anti-rotation and high breaking force. The V-shaped strand design increases the contact area between strands, and the rope body has excellent rigidity and stability. At the same time, the surface is smooth and the wear resistance is significantly better than that of ordinary structures.

It is suitable for scenes with strict requirements for low rotation and heavy loads, such as large crane luffing mechanisms, wind power equipment hoisting, bridge erection, etc. It can maintain stable performance in high-frequency operations and complex stress environments, and is an efficient load-bearing choice in heavy engineering.

Product Data

Anti-rotation wire rope(Ungalvanized and Galvanized).

A multi-strand wire rope that produces reduced torque or rotation when loaded. Anti-rotation wire ropes differ from standard wire ropes because their counter-rotating lay design reduces the torque on the wire rope. Anti-rotation wire ropes break and wear differently than those of standard construction wire ropes.

1. Rotation-resistant wire ropes have at least 15 outer strands, with three strands "wrap around the core", little or no tendency to rotate, or transmit little or no torque when guided.

2. The outer layer of the anti-rotation wire rope has at least 10 or more strands, and there are more than two layers of strands
"wrap around the core", which has obvious anti-rotation performance.

3. Anti-rotation wire rope has no more than 9 strands in one outer layer, with two layers of strands around the core and limited anti-rotation performance.

When using anti-rotation wire rope, a safety factor of at least 5.0 should be selected.

Product Details

Wire Rope 4VX39S Features：

The characteristics of 4VX39S wire rope revolve around anti-rotation, high strength and structural stability, which are specifically manifested as follows:
Unique strand design: It adopts a 4-strand V-shaped (triangular) special-shaped strand structure, each strand contains 39 Siru-style (S-shaped) arranged steel wires, and the compaction process makes the strands fit tightly, the rope cross-section is more regular, the overall rigidity is outstanding, and the deformation resistance is strong.
Excellent anti-rotation performance: The symmetrical structure of the 4 strands greatly reduces the torsion tendency under load, especially when heavy loads are hoisted, which can reduce the self-spin of the rope and the deflection of heavy objects, improve operational safety, and is suitable for scenes with high requirements for low rotation.
High strength and wear resistance: The compaction process increases the contact area between the steel wires, and the breaking tension is higher than that of ordinary steel wire ropes with the same diameter; the surface is smooth, the friction loss with the pulley and drum is small, the wear resistance and fatigue resistance are significantly improved, and the service life is extended.
Adaptable to complex stress environments: It can evenly withstand composite loads such as tension, bending, and extrusion, has strong impact resistance, is suitable for high-frequency operations such as large-scale mechanical amplitude change, frequent retraction and extension, and performs stably in scenarios such as wind power and bridge engineering.

Wire Rope 4VX39S Typical applications：

4VX39S wire rope is mainly used in engineering scenarios with heavy loads, low rotation requirements and high frequency operations due to its strong anti-rotation, high strength and wear resistance:
Large lifting machinery: As the luffing rope and main hoisting rope of tower cranes and crawler cranes, its low rotation characteristics can avoid torsional swing during heavy lifting, and is suitable for high-precision operation requirements such as high-rise building lifting and heavy equipment transportation.
Wind power engineering: It is used for blade lifting and tower traction of wind turbines. It can withstand large loads during wind turbine installation, and its anti-rotation design can reduce the risk of rope entanglement during high-altitude operations and ensure installation safety.
Bridges and infrastructure: As the load-bearing rope for lifting steel box girders and prefabricated components in bridge erection, its high strength and fatigue resistance can cope with frequent lifting and lowering operations, and is suitable for the transportation of heavy components in cross-river and cross-river projects.
Ports and heavy-duty logistics: Suitable for the luffing mechanism of port gantry cranes and the lifting system of container reach stackers. Its wear-resistant properties can cope with high-frequency friction with pulleys, improving the continuous operation efficiency of the equipment.

FAQ

Q1: Is the anti-rotation property of 4VX39S absolute? Why does torsion still occur sometimes?

A: It is not absolutely anti-rotation: its 4-strand symmetrical structure can only greatly reduce the torsion tendency. It may still torsion if the following conditions exist:

The load exceeds 80% of the rated value, or the instantaneous impact load is too large;

The contact angle deviation between the rope body and the pulley or drum exceeds 5°, resulting in uneven force;

The rope body is pre-twisted during installation (such as incomplete stress release during wire release).

If abnormal torsion occurs, stop the machine immediately for inspection and adjust the load or equipment angle.
Q7: Compared with ordinary wire ropes, what are the special requirements for lubrication and maintenance?

A: The lubrication method needs to be adjusted for the compacted strand structure:

Highly permeable grease (such as synthetic ester grease) must be used, because the gap between V-shaped strands is fine and dense, and ordinary grease is difficult to penetrate into the contact surface of the steel wire;

Before lubrication, use a high-pressure air gun to remove dust between strands (ordinary brushes cannot clean the gaps) to avoid impurities mixed with grease to form abrasives;

In marine and dusty environments, the lubrication cycle needs to be shortened to 50%-60% of ordinary wire ropes to prevent corrosion or accelerated wear.
Q6: A small number of scratches on the surface of the rope body will affect its use?

A: It needs to be judged based on the depth of the scratches:

If only the surface coating is worn (no exposed steel wire), and the length is less than 1/3 of the rope diameter, it can continue to be used and monitored more closely;

If the scratch depth exceeds 10% of the steel wire diameter, or the steel wire matrix is exposed, it needs to be stopped immediately - because the compacted structure of 4VX39S relies on overall force balance, local damage may cause stress concentration and accelerate fracture.
