Cortland Endless Grommet Slings

Grommets are manufactured by taking the base rope and splicing the ends together to form a continuous loop.

Compared to eye and eye slings, they have increased strength with little to no increase in the chosen rope diameter due to two legs holding the load. They can also be manufactured in shorter lengths because extra material to build the eyes is not needed.

The challenge of endless grommet slings is that their minimum breaking load is directly controlled by the diameter of the pin that they are mounted on. The values below are calculated on an 8:1 D:d.

Refer to Plasma® Braided Slings PDF for more information on how to covert to other diameters.

Patented Plasma® 12×12 braided construction creates strong lifting slings that are perfect for long length lift situations.

Cortland’s patented Plasma® rope is strong enough for very heavy lifts yet durable enough for repeated use. Our exclusive Plasma technology processes UHMWPE fibers into maximum strength efficiency. These fibers are then braided into a torque-free rope which is firm, yet flexible, and offers the ability to produce very long lengths. Utilizing the largest 12-strand braider in the world, Cortland can produce large diameters (up to 200mm) and long lengths.

Unlike wire ropes and jacketed round slings, Plasma 12×12 rope slings are easy to inspect. If repair is needed, the 12×12 construction offers the ability to replace worn strands. Plasma 12×12 rope slings are also neutrally buoyant, and do not absorb water, so there is no reduction in lifting capacity once immersed.

These slings are popular in offshore crane lifting systems because of their light weight and ease in handling.
