When replacing a wire rope, refer to the relevant Original Equipment Manufacturers recommendation and rope test certification. To ensure safe and efficient operation, replacement ropes should conform to the specified nominal rope diameter and be at least equal to the required strength originally specified. Additionally, the wire rope construction selected should provide similar or improved working properties for resistance to rotation, bend fatigue, crushing, abrasion and corrosion. Where an original wire rope is to be supplied, or where the required working conditions have changed, KISWIRE should be consulted to obtain the best possible advice and recommendations.

Anchor Lines:

• Rope construction: Class 6x36 IWRC and greater.
• Large diameter outer wires for optimum resistance to wear and corrosion.
• Wire protection by galvanising or ALUMAR.
• Compact strand (CMP) for increased strength, improved contact area,reduced tread pressures and sheave wear.

Drilling Lines:

Rope construction: 6x19 and 6x26 for constructional stability.
Compacted strand (CMP) provides:
• Improved spooling on the drawworks.
• Greater contact area for reduced sheave and groove wear.
• High resistance to abrasion and pressure.
• Higher strength.
• Improved fatigue life.

Crane Ropes:

Appropriate rope constructions to achieve optimum fatigue life.
Where the expected working life is in excess of 1 year, ALUMAR protection is recommended.
Compact Strand (CMP) offers:
• Higher strength and improved spooling properties
• Greater contact area for reduced sheave wear
• Improved fatigue performance

Winch Ropes:

Optimum flexibility to allow efficient rope operation around sheaves, drums and capstans.
Effective protection of all wires by galvanising/ALUMAR.
Appropriate lubrication during manufacture.
Rope selection should be determined through consultation with KISWIRE.
