SK78 Prisma-Siri® S-12 DB Rope

SK78 Prisma-Siri® S-12 DB are unique High-Performance ropes with excellent properties that meet the requirements of the most demanding applications. They consist of a 12strand SK78 Prisma® Shielded load bearing core and a protective braided jacket. This rope construction is firm, round and torque free.

APPLICATIONS: MOORING / TOW LINES / STS OPERATIONS (to be used with synthetic tails) / ANCHORING / OFFSHORE / YACHTING

There are three options for the jacket:

These special jackets provide extra protection against abrasion, UV sunlight and environmental degradation. The jackets are repairable with the use of repair kit.

The special Prisma® Shield technology and the elaborate in-house heat-setting process upgrade the SK78 fiber to a level of superior performance. The application of Prisma® coating is performed on the fiber level and protects the SK78 fibers from abrasion and UV radiation. In the end, the whole process guarantees a top-quality rope with extra high strength efficiency and excellent abrasion resistance.

When compared to wire ropes, SK78 Prisma-Siri® S-12 ropes are stronger (for the same weight), lighter (making it easy and fast to handle), safer to use and cost-saving (minimum maintenance needs, no greases, faster operating times).
