non rotating wire rope specifications pricelist

Rope Services Direct supplies a variety of anti-spin non rotating wire rope (also called rotation resistant wire-rope). All standard rope wirehas a tendency to develop torque and therefore prone to rotation, whereas non-rotating wire ropes are designed so that the wire-rope outer rotational force naturally counteracts the inner strands rotational force. This is in the event that a rope is subjected to a load.

Rope elongation and rotation occurs on standard ropes when loaded, which can therefore spin the load, quite possibly out of control, which can be dangerous. When the rope rotates in this way the strands will begin to unravel. This causes the rope to lose strength and will undoubtedly fail, which could be catastrophic. It is for these reasons that non rotating wire rope is commonly used for many types of lifting applications including main hoist rope, whip rope,crane rope, off-shore and deck rope and more.

Non rotating wire rope or rotation resistant wire rope has a different construction to standard. as wires and strands are not laid in the same direction like they would be on standard rope. Inner and outer strands of wires are laid in opposite directions. For example the inner may be constructed in left hand lay whilst the outer layer is in right hand lay. The nature of this construction means that torsional forces on the inner and outer wires/strands will counteract each other and therefore minimising the risk of unraveling.

It is worth noting that the number of strand layers will have an effect of the resistance of rotation. A 2 layer rope has less resistance than a 3 layer rope. Therefore the more layers the rope has the greater rotation resistance it will have.

These types of ropes can be classified as spin resistant, rotation resistant or non rotation resistant. Classed on the basis of the number of rotations a certain length of rope does when a force of 20% of the MBF is applied; with 1 turn or less the rope will be classified as non rotating; with rotations between 1 & 4 the rope is classed as low rotation and for rotations between 4 & 10 the rope will be classified as spin resistant, any higher and the rope is NOT rotation resistant at all.

Correct usage and care with handling will prolong the working life. This is due to the friction on the inner wires caused by the strand crossover’s which will eventually cause the inner wires to break up. This is more apparent on non rotating wire rope with two layers. Ropes with 3 or more strand layers will distribute the radial pressures more evenly. Which will reduce friction and stress on the inner wires.

Regular,thorough inspectionsof non rotating rope are essential due to the fact that it is the inner strands that often break first and broken internal wires often go unnoticed as they are difficult to see.Rope Services Direct offer inspectionson all rope with certification issued on completion.

Holding both ends of the rope will prevent unraveling. Correctly fitted terminations will help to prevent damage. Kinking and unraveling may occur and they can also have an effect on the rotational balance if not fitted correctly.

19x7 wire rope is recommended for hoisting unguided loads with a single-part line. The rotation-resistant properties of this rope are superior to those of the 8x19 class wire ropes, and are secured by two layers of strands. The inner strands are left lay, while the 12 outer strands are right lay, which enables one layer to counteract the other layer’s rotation.

Galvanized wire rope (steel) features a compressed zinc coating for providing excellent corrosion resistance. With a higher break strength, yet lower price than stainless steel wire rope, galvanized steel wire rope is widely used in general engineering applications such as winches and security ropes.

The bright class of industrial wire rope is produced without a surface treatment—making the rope less likely to untwist or kink while giving it a stronger crush resistance than lay ropes. Generally, they are fully lubricated to protect the rope from rust and corrosion. Also available in USA-made.

Rotation resistant wire rope refers to a series of steel ropes which minimizes the tendency to spin or rotation under load. These wire ropes boast special design - the outer layer is twisted in the reverse direction of inner layers for counteracting torsional forces generated from multi-layers of strands.

To achieve the resistance against the spin and rotation, all wire ropes are composed of at least two layers of strands. In general, more layers a rotation resistant wire rope has, more resistance it will boast. For example, 2-layer ropes is much easier to spin and rotate than 3-layer ones. Meanwhile, if one end of free rotation is allowed, 2-layer rope can only develop 55% to 75% of its breaking strength comparing with 95% to 100% of 3-layer ropes.

The 3-layer rope with more outer strands is capable to distribute more radial pressure onto inner layers and ideal for larger mobile such as all tower cranes.

Wire ropes with 8 to 10 strands & 2-layer constructions without reversely twisted inner strands have very similar appearance to rotation resistant wire ropes, but they are not.

Rotation resistant wire ropes are considered to be less stable needing to be handled and installed with great care. They must be taken to avoid high loads with small diameter sheaves.

There are a variety of cables and wires that are used for various purposes. They can either be hidden underground or pass overhead. Crane Cable is one such cable wire rope made out of several strands of metal wires that are twisted together into a helix form to make them into a single rope. Initially, wrought iron was used to make these Crane Cables however, these days steel is the primary material used. Apart from this high carbon steel and galvanized steel are also used in manufacturing these cables. Dents or flaws in the ordinary link chain can lead to severe failure whereas, damage in these EOT Crane Cablecan be easily covered up. Ther are ideally used for lifting elevators, in the transmission of mechanical power, and in cranes.

Crane Lifting Cables are resistant to corrosion and have excellent ductility for optimal fatigue. They have a high breaking strength compared to steel crane wire rope. The radially elastic rope structure absorbs the dynamic force thus giving it high impact resistance. Crane Cable Wires are said to be cost-effective as a strong and durable structure helps in reducing maintenance costs and downtime. They can be coated with bright phosphate or galvanized depending upon the customers’ requirements.

Crane Electrical Cable is available in rotating, rotation, compact, or non-compact structures. Most of the wire ropes have the tendency of developing torque and are thus prone to rotation. However, non-rotation wires are designed in a way that their outer rotation naturally counteracts the inner strands rotation. Crane Hoist Cable can be used in tower crane ropes or offshore crane ropes.

Overhead Crane Cable reel should be capable of winding it automatically. The drive torque of the crane cable should not be less than the max winding torque of the winding crane cable. The cable conductor should be as small as possible when the Crane Rope laying acts on the traction force.

The Crane Wire Rope does not have a reinforcement core, the maximum tension allowed on the copper conductor cross-section is 20N/mm2. We at Bhuwal Insulation Cable Pvt. Ltd. not only provide you the best quality Tower Crane Cable but also the parts required to assemble them. Our long-standing reputation in providing the best quality product at a competent price has made us one of the leading Crane Cable manufacturers in India.

Cables or cords are the wire ropes which have diameters smaller than 3/8 inches, While wire ropes have diameters greater than 3/8 inches. if there are two or more wire concentrically laid then it is known as strand

6 by 19 is a type of wire rope which can withstand fatigue resistance, abrasion and prevents crushing on drums. it is available in diatmeter range of 3mm to 6 mm. While 7 by 19 are wire rope which has diameters ranging between 3 mm to 16 mm which can be use in different applications.

Inspect regularly for visible damage, distortion, elongation, corrosion, cracks, nicks or abrasion, which may cause failure or reduce the strength of the Wire Rope.

Ropes are materials produced to perform various tasks such as lifting, lowering, tying and carrying an item or load. The parts with the small rope structure bend in one direction and the arm is formed. These arms are brought together again and twisted to form ropes. Ropes are produced with different raw materials according to the usage area and the work to be done. It is among the rope types that are frequently used in steel ropes.

Steel core steel rope is a type of rope in which the arm in the core of the rope and the arms on the edges are produced by forming steel wires. Steel core steel ropes are very durable and strong ropes as they are produced entirely from steel. Each type of steel core wire rope offers the opportunity to do professional work in different areas of use with its features.

Ropes are used in different ways by undertaking various functions such as pulling, holding, lifting and lowering. The usage areas of steel core steel ropes are generally as follows;

Steel core steel ropes are produced in line with the needs of the usage area. Since it is different for each working area and shape, rope types with different properties are designed and produced. The most commonly used types of steel core steel rope are as follows;

Ropes offer various advantages to the user thanks to their features. Increasing work efficiency and quality is its most important advantage. In addition, they offer a great advantage in providing the necessary conditions for occupational safety. The properties of steel core steel ropes can be listed as follows;

Steel core steel ropes are different from each other in terms of design, production and use. The cost figure for each product also changes based on these reasons. The prices of steel core steel ropes are determined separately for each type. In this case, it is more accurate to obtain price information after determining the type of steel rope that is suitable for the operation and the work to be done.

Non-rotating wire ropes are designed so that the wire-rope outer rotational force naturally counteracts the inner strands rotational force in the event of a load applied.

Rather than all wires and strands being laid in the same direction, a rotation resistant wire rope consists of inner strands being laid in the opposite direction to the outer layers, for example the inner may be constructed in left hand lay whilst the outer layer is in right hand lay. This construction means that torsional forces on the inner and outer wires / strands will counteract each other and so minimise the risk of unraveling.

Using an ordinary lifting wire rope for a job or equipment which demand a non-rotating wire rope si very dangerous and it presents the following risks:
