Wire Rope Grommet Slings

Wire Rope Grommet Slings

Grommets either have a wire rope body or a body made up of six strands which are laid helically around a strand core. Either a hand-spliced - strand laid, turn back spliced, or a mechanically spliced. The wire rope grommet sling is an endless sling.

Vertical or straight attachment is simply using a sling to connect a lifting hook to a load. The full-rated lifting capacity of the sling may be utilized, but must not be exceeded. A tagline should be used to prevent load rotation which may damage the sling. When two or more slings are attached to the same lifting hook, the total hitch becomes, in effect, a lifting bridle. The load is then distributed equally among the individual slings.

Choker hitches reduce the lifting capability of a sling. This method of rigging affects the ability of the wire components to adjust during the lift. A choker is used in three different instances. One being, when the load will not be seriously damaged by the sling body. Two, when the sling is damaged by the load. Lastly, when the lift requires the sling to snug up against the load. The diameter of the bend where the sling contacts the load should keep the point of choke against the sling body. Hence, it should never be against a splice or the base of the eye. When a choke is used at an angle of less than 120 the sling rated capacity must be adjusted downward.

Basket hitches distribute a load equally between the two legs of a sling-within limitations described below. The capacity of a sling used in a basket is affected by the bend, or curvature, where the sling body comes in contact with the load. Consequently, just as any wire rope is affected and limited by bending actions, as over a sheave.
