SLINGS AND RIGGING GEAR KITS
The NCF has slings and rigging gear in the
battalion Table of Allowance to support the rigging
operations and the lifting of CESE. The kits 80104,
84003, and 84004 must remain in the custody of the
supply officer in the central toolroom (CTR). The
designated embarkation staff and the crane test
director monitor the condition of the rigging gear. The
rigging kits must be stored undercover.
WIRE ROPE SLINGS
Wire rope slings offer advantages of both strength
and flexibility. These qualities make wire rope
adequate to meet the requirements of most crane
hoisting jobs; therefore, you will use wire rope slings
more frequently than fiber line or chain slings.
FIBER LINE SLINGS
Fiber line slings are flexible and protect the
finished material more than wire rope slings; however,
fiber line slings are not as strong as wire rope or chain
slings. Also, fiber line is more likely to be damaged
by sharp edges on the material being hoisted than wire
rope or chain slings.
Chain slings are frequently used for hoisting
heavy steel items, such as rails, pipes, beams, and
angles. They are also handy for slinging hot loads and
handling loads with sharp edges that might cut the
Chain sizes, inspection, safe working load, and
handling and care will be discussed after wire rope and
fiber line, as their characteristics have been discussed
in previous chapters.
USING WIRE ROPE AND
FIBER LINE SLINGS
Three types of fiber line and wire rope slings
commonly used for lifting a load are the ENDLESS,
the SINGLE LEG, and the BRIDLE slings.
An ENDLESS SLING, usually referred to by the
term sling, can be made by splicing the ends of a piece
of fiber line or wire rope to form an endless loop. An
endless sling is easy to handle and can be used as a
CHOKER HITCH (fig. 6-14).
Figure 6-14.Endless sling rigged as a choker hitch.
A SINGLE-LEG SLING, commonly referred to
as a strap, can be made by forming a spliced eye in
each end of a piece of fiber line or wire rope.
Sometimes the ends of a piece of wire rope are spliced
into eyes around thimbles, and one eye is fastened to
a hook with a shackle. With this arrangement, the
shackle and hook are removable.
The single-leg sling maybe used as a choker hitch
(fig. 6-15, view A) in hoisting by passing one eye
through the other eye and over the hoisting hook. The
single-leg sling is also useful as a double-anchor hitch
(fig. 6-15, view B). The double-anchor hitch works
