The document provides information about wire rope slings used for lifting, including their construction and rated lifting capacities. It describes how flemish eye splices are formed using pressed metal sleeves. It also notes that rated lifting capacities are based on a design factor of 5 and sling angles of at least 30 degrees. Rated capacities are reduced for bridle slings and choker hitches when the angle between the legs is less than 120 degrees.

Wire Rope Slings
Single Part Body
Mechanical Splice
Eyes are formed using the flemish eye splice. Ends are secured by
pressing a metal sleeve over the ends of the strands of the splice.
Pull is directly along the centerline of rope and eye. Gives most
efficient use of rope capacity and is economical.

Rated Capacity for two-legged bridles, whether
used as chokers or with hooks or other end fixtures, is
affected by rigging angles, the same as straight slings
in basket hitches. Note reduction in rated capacity as
legs spread to wider lifting connections.
Multi-legged bridles – with two, three or four straight legs – are offered with
plain eyes, thimble eyes, open or closed sockets, shackles and tumbuckles. If required,
rings or alloy oblong links can be supplied rather than the pear shaped links shown.
Rated capacities for 3 & 4 leg bridle slings are based on equal leg slings with the
sling angle being the smallest angle measured between any sling leg and the
horizontal plane of the load. For other applications, consult our Fabricated Products
Engineering Department.

Grommet Choker Hitch Rated
Wire Rope Slings Capacity Adjustment
For wire rope slings in choker hitch when angle
of choke is less than 120°.
*Percent of sling rated capacity in a choker hitch.
If a load is hanging free, the normal choke angle is approximately
135 degrees. When the angle is less than 135 degrees an adjustment
in the sling rated capacity must be made. Choker hitches at angles
greater than 135 degrees are not recommended since they are
unstable. Extreme care should be taken to determine the angle of
choke as accurately as possible.
In controlled tests, where the angle was less than 120 degrees, the
sling body always failed at the point of choke when pulled to
destruction. Allowance for this phenomenon must be made anytime
a choker hitch is used to shift, turn or control a load, or when the pull
is against the choke in a multi-leg lift.
