Erickson’s synthetic slings are manufactured to ensure a design factor of 5:1. This design factor is a factor which is divided into the nominal strength of a sling to arrive at the WLL (or Rated Capacity). This factor is necessary to allow for wear, abrasion, damage, and variations in load which are not always readily apparent to the sling user BUT DOES NOT COVER FOR INSUFFICIENT EDGE PROTECTION OR PROTECTION AGAINST CUTTING. Hitch Capacity - Basket: 4800 lb./2177 kg. Choker: 1920 lb./870 kg. Vertical: 2400 lb./1088 kg.
