vertical plane as shown in Figure 5, provided that an angle of
loading of 5 degrees or less from the vertical may be
considered a vertical angle of loading.
(2) Basket hitch means 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.
(3) Braided wire rope means a wire rope formed by

means a wire rope sling made endless by joining the ends of
a single length of cable laid rope with 1 or more metallic
fittings.
(2) Cable laid grommet-hand tucked means an endless
wire rope sling made from 1 length of rope wrapped 6 times
around a core formed by hand, tucking the ends of the rope
inside the 6 wraps. 2
(3) Cable laid rope means a wire rope composed of 6
wire ropes wrapped around a fiber or wire rope core.
(4) Cable laid rope sling-mechanical joint means a wire
rope sling made from a cable laid rope, with eyes fabricated
by pressing or swaging 1 or more metal sleeves over the
rope junction.
(5) Choker hitch means a sling configuration with 1 end
of the sling passing under the load and through an end
attachment, handle, or eye on the other end of the sling.
(6) Coating means an elastomer, or other suitable
material, applied to a sling or to a sling component to impart

sling. (See Figure 3.)
