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:

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

Main and auxiliary hoist line for mobile and for all types of construction tower cranes which require a high strength rotation resistant rope construction.

The large number of outer strands distribute the pressures introduced by sheaves and drum more evenly onto the core minimizing the danger of unexpected rope failures because of undetected core deterioration.

19X7 is a non-flexible wire rope. It is used for a wide range of applications, example of applications for non-rotating wire ropes include the following

Non-rotating wire ropes are made so that the outer rotational force of the wire rope naturally balances the rotational force of the inner strands. Standard rope wire has a tendency to create torque and is thus prone to rotation.

In the past, wrought iron chains, which had a history of mechanical failure, gave rise to wire rope. Defects in solid steel bars or chain links can result in catastrophic failure, whereas flaws in the wires that make up a steel cable are less important because the other wires can readily carry the strain. Although friction between the various wires and strands wears the rope over time, it also aids in temporary repair of minor flaws.

This pertains to the scenario in which a load is applied to a rope. In order to create a composite rope known as wire rope, numerous strands of metal wire are twisted into a helix in a pattern called lay rope. A larger diameter wire rope is made up of several strands of this lay rope arranged in a style called cable laid.

The global non rotating wire rope marketaccounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.

In terms of value, Regular Type of Lay is the fastest-growing Type of Lay for Steel Wires.Lang lay ropes spool poorly in a drum and are less naturally rotation-resistant and resistant to crushing forces than regular lay ropes.

They are employed in a variety of fields, including mining, oil and gas, construction, fishing, and marine. To address the unique wire rope needs of the new cranes, South Korean speciality high carbon steel wire products producer “Kiswire” is growing its operations in India. They not only serve as OEM suppliers to numerous global crane manufacturers, like Tadano and Kobelco, but they also actively pursue the Indian Replacement Market.
