Plasma® HMPE Rope Created for Heavy Lift Operations

The Challenge
World’s Largest Braided RopeA European client needed to create an enormous lifting sling, but the lifting requirements exceeded the manufacturing capability of most providers.

The Solution
The best solution to the problem was patented PLASMA® synthetic fiber in a 12x12 braided configuration; only available through Cortland.

This unique rope was created from more than 52,000 individual Plasma® yarns using Cortland’s patented 12x12 braiding technique. This exclusive braiding process combines individual 12-braided ropes into a finished 12-strand rope of exceptional strength and flexibility. The finished size of this particular rope was 168mm with a minimum spliced tensile strength of 1893MT.

Despite the exceptional size, this rope is 7 to 8 times lighter than a comparable steel rope, yet is much easier to handle and splice. The rope was used in a grommet configuration with an MBL exceeding 3044MT for heavy lift operations.

The Plasma® Process
Plasma® 12 Strand is the highest strength synthetic rope available. Plasma® is manufactured from high performance Honeywell Spectra 900® Fiber that has been enhanced by Cortland’s patented recrystallization process.

The Plasma® process is especially effective in medium to large diameter ropes where strengths are over 50% higher and creep is significantly less than that of standard Spectra® 12 strand. Its soft, torque free braided construction provides easy handling.

12x12® Braided Construction
The 12x12 Construction is designed specifically for high modulus, high strength fibers such as Spectra®, Plasma® enhanced Spectra®, BOB®, and Vectran®. This patented construction addresses the most critical properties of the fibers to provide a very high strength translation efficiency for larger ropes. This design allows for long lay lengths, making the rope more flexible for bending applications and rope that is easy to inspect and can be quickly spliced using standard 12 strand splicing techniques. Plasma® 12x12 is a 12-strand single braided rope in which each of the 12 strands is, in turn, a 12-strand rope, or braided primary strand.
