Turbine rotor installation and maintenance with Twin-Path® slings.

EE – This product is made to be an eye & eye sling only. Usually an eye & eye sling is made from a round sling with a sleeve over it to form the eyes at each end. This sling is light, strong and less expensive than a round sling with a sleeve. It is manufactured using K-Spec® core fibers and Covermax. These slings have 1% stretch at Rated Capacity compared to polyester braided round slings which can stretch up to 9%. Riggers have told us that they have some applications where they want an eye & eye sling only and this is the one with all of the Twin-Path® features in a strictly eye & eye product. However, be aware that you can NOT rotate the wear points as you can with regular “endless” style Twin-Path® Slings.
