tiMe - Lightweight fiber slings offer significant reductions in rigging time and manpower. They are 1/7th the weight of steel wire rope or more. In heavy lift projects, installation crews also receive savings in transportation and storage costs.

HSe benefitS - Lightweight rope and round slings offer superior flexibility which translates into fewer rigging injuries. They are also soft of hand causing little damage to rigger or expensive payloads.

Longer SerViCe Life - Modern high strength synthetic fibers are remarkably durable and will not rust, corrode or fish-hook. They are not affected by fresh or salt water. Wear points can be protected from abrasion, cutting and heat damage. They are designed for multiple lift use and are easy to inspect.

CuStoM deSign SoLutionS - Cortland slings are available with innovative integrated hardware solutions – emphasis is on lightweight efficient security. Whether it is ultra short lengths with precise length tolerances, or large diameter long lengths in various sling configurations, Cortland can meet your lifting needs.

engineered for PreCiSion Lifting - Cortland can solve your precision lifting problem. Our engineering and sales staff has the experience necessary to create a lightweight lifting sling from the extensive high modulus synthetic fiber options available. We understand the harsh marine working environment first hand and put this knowledge to work for you in creating a Selantic sling and associated hardware designed for your specific needs.

MateriaL SeLeCtion - Each of our high strength and flexible Selantic endless loop slings use material specific to your application. We carefully select the optimal core material based on our experience and your application requirements, from our wide array of high modulus synthetic fiber options. These core materials include HMPE, Aramid as well as other synthetic fibers.

CuStoM ProteCtiVe CoVerS - To protect potential chafe areas from wear, the selected core material is encased in a protective cover to ensure a durable and long-lasting lift solution. These tough and highly visible protective jackets can also be matched to your specific needs depending on environmental and usage considerations.

SPeCiaLized HardWare - Cortland offers specialty compliant hardware engineering services with all products. Thimbles, shackles, hooks and spreader bars can all be custom engineered into the initial sling design.

synthetic fiber rope slings

Patented 12 x 12 Strand ConStruCtion - The 12 x 12 rope construction design produces a finished braid which is firm yet flexible, and offers the ability to produce extremely long lengths. Utilizing the largest 12-strand braider in the world, Cortland can produce extremely large diameters (up to 200mm) and lengths of Plasma® rope. Fabricated into lifting slings, 12 x 12 construction produces a very compliant yet durable sling.

eaSy to rePair and inSPeCt - Unlike heavy firm construction wire ropes and jacketed round slings, Plasma® 12 x 12 rope slings are extremely easy to inspect. Inspectors can easily review external or internal wear. If repair is needed, the 12 x 12 construction offers the ability to replace worn “strands”.

neutraLLy buoyant - Unlike steel wire rope slings, Plasma® 12 x 12 rope slings are neutrally buoyant in water so there is no reduction in lifting capacity once immersed. These ropes are gaining popularity as sling-extensions to offshore crane wire rope lifting systems because of their light weight and ease in handling. Plasma® HMPE fibers also do not absorb water.

WorLd’S StrongeSt roPe for itS WeigHt - Cortland’s patented Plasma® rope is strong enough for very heavy lifts yet durable enough for repeated use. Our exclusive Plasma® technology processes HMPE fibers into maximum strength efficiency. These fibers are then braided into a torque-free rope. Plasma® low elongation properties, its high strength, flexibility and light weight make it a perfect replacement for large diameter wire rope slings. In a same strength and size comparison, Plasma® ropes are only 1/7th the weight of common steel wire rope.

Plasma® 12 x 12 rope sling construction is highly advantageous for inspection and repair. However, to add extra chafe and cut protection to eye termination areas or on the sling body itself, Cortland offers a wide array of synthetic fiber options which range by price and performance. Cortland chafe sleeves can be replaced and work well on new or used rope. All options are available from the rope mill or authorized fabricating distributors.

nxt CHafe SLeeVe - A tightly braided nylon chafe sleeve with proprietary heavy marine polyurethane coating for use in extreme chafe applications. Excellent choice for eye termination or selected area body placement; braid-spliced or seized in place. Covers rope sling sizes from 24mm diameter through 92mm diameter.

Sx CHafe SLeeVe - combining the lightweight, non water-absorbing properties of HMPE fiber in a tightly braided cover sleeve, SX offer the best cut and abrasion resistance of all chafe gear. SX has a high visibility polyurethane coating. Primary usage is in eye termination protection and can be seized or spliced into the 12 x 12 construction.

SPeCtra-Lite CHafe SLeeVe - Cortland’s Spectra-lite chafe sleeve is a tightly woven HMPE fiber fabric material. Available in a sewn tube or in a tubular sleeve with a hook and loop fastening system, this sleeve can fit over eye terminations of rope slings, or be placed on the sling body for extra protection against cutting and abrasion. Cortland’s Spectra-lite will not absorb water, is “thin-walled” and very lightweight. It can cover any size rope sling from 24mm diameter and larger.

adequate chafing protection is important for synthetic slings, and Cortland offers several different wear protection products

Plasma® 12 x 12 rope sling specifications - vertical straight pull

for a full chart of MbL, WLL and diameter sizes offered, please contact Cortland: cortlandcompany.com

Minimum break Load (MbL) is determined in accordance with US CI 1500-02 Test Methods for Fiber Rope. Tests are conducted on new spliced rope in lab conditions, therefore no further reductions from published strength are necessary to calculate sling MBL. Rope is cycled (10) times to 50% rated load then pulled to destruction. MBL is determined using bend factor D:d ratio at 3:1. For bending strength efficiencies or D:d less than 3:1, please contact Cortland.

endless grommet Sling MbL: is calculated as 1.65 times the eye-to-eye sling strength, assuming a D:d ratio of 8:1 or more for pins or connections; if less than 8:1 or greater than 2:1 use 1.6 times the eye-to-eye strength. For D:d ratios 2:1 or less, please contact Cortland.

for Sling fabrication Strengths in Hitch Configurations, (e.g. choker, etc.): please refer to pertinent lifting standard or contact Cortland.

nominal rope diameter and Circumference: as published represents O.D. (outside diameter) after stabilization. Under load, diameters will decrease from relaxed measurements. Relaxed new rope diameters may be at least 10% larger than loaded or proof-loaded sizing.

Weights: are calculated as linear density under standard preload (200d²) plus 4%.

note: NX Plus and NXT chafe protection is also available in polyester (DX Plus and DXT) which offers better chafe protection than nylon, Other colors available upon request.
