“Angle of loading” is the inclination of a leg or branch of a sling measured from the horizontal or vertical plane as shown in Fig. N-184-5; provided that an angle of loading of five degrees or less from the vertical may be considered a vertical angle of loading.
“Basket hitch” is a sling configuration whereby the sling is passed under the load and has both ends, end attachments, eyes or handles on the hook or a single master link.
“Braided wire rope” is a wire rope formed by plaiting component wire ropes.
“Braided wire rope sling” is a sling composed of multiple wire rope legs with the top ends gathered in a fitting that goes over the lifting hook.

“Cable laid grommet-hand tucked” is an endless wire rope sling made from one length of rope wrapped six times around a core formed by hand tucking the ends of the rope inside the six wraps.
“Cable laid rope” is a wire rope composed of six wire ropes wrapped around a fiber or wire rope core.
“Cable laid rope sling-mechanical joint” is a wire rope sling made from a cable laid rope with eyes fabricated by pressing or swaging one or more metal sleeves over the rope junction.
“Choker hitch” is a sling configuration with one end of the sling passing under the load and through an end attachment, handle or eye on the other end of the sling.
