Abstract :
With these test results, lightweight synthetic Plasma® 12 × 12 rope has now proven its performance capabilities in large sizes suitable for use in the most demanding of operations. The “real-size data” created is significant in positioning high modulus synthetic ropes as a viable alternative to steel wire rope and chain in ultra-high strength applications. The tests conducted in May essentially validated the Cortland design and manufacturing processes, thereby enabling Cortland to publish a finalized product strength chart with confidence. Given the high modulus rope application success in smaller diameter applications, combined with the new interpretative knowledge gained during this testing, it is anticipated that a more rapid conversion from wire rope to synthetics in several critical lifting applications may be viewed in a more favorable light. Furthermore, Cortland has not reached the upper limit of the sizes that can be produced and will continue to test new sizes and materials.
