nylon eye and eye web sling


Nylon slings are a strong, lightweight, and very flexible rigging solution trusted by industries throughout the world. Our American-made nylon slings are treated for abrasion resistance, and can be worked in temperatures up to 180° F. With high resistance to alkaline environments, nylon lifting slings are ideal for many applications, but should never be used in acid conditions.

    triple leg chain sling


    Chain slings are used primarily for overhead lifting in conjunction with a crane or lifting device. Standard sling configurations consist of chain branches which are affixed on one end to a master link or ring with some type of attachment, usually a hook, affixed to the opposite end.

    Chain Lifting Slings provide excellent performance in harsh environments. When using a chain for overhead lifting, an alloy grade, either grade 80 or 100, is recommended. Both are manufactured in house by HSI from special alloy steel and engineered for a superior combination of strength and durability.

    In addition to standard wire rope slings, HSI can manufacture both HSI and Slingmax® brand Special Application Slings.

    As sling manufacturing experts with nearly a century of experience splicing slings, HSI has the ability to manufacture hand-spliced wire rope slings, which retains the same rated capacity as swaged slings of the same diameter. These slings are especially useful in choker hitches where swages catch on the rope. Our Wayne Special sling offers one swage eye and one hand-tucked eye. Other options include cable-laid slings, which are comprised of seven individual wire ropes for increased flexibility characteristics.

    Slingmax® specialty sling options include Tri-Flex® wire rope slings, which utilize three parts to achieve both increased strength and flexibility; and Gator-laid® slings, which are the most efficient and flexible multipart heavy-lift wire rope slings available on the market.
