Splicing the ends of a piece of wire rope makes an
grommet slings, endless grommet slings. It is simple to handle and can be
used in several different ways. The endless grommet slings, braided belt
slings are most commonly used as a choker hitch. When the endless sling is
used as a choker, user passes it around the object forming a loop on top of
the object. The other end is passed through this loop, pulled tight and
attached to the cargo hook. User spread apart the two parts of the sling on
the bottom of the object.
Double part endless slings are available in both ferule spliced and hand

GROMMET WIRE ROPE SLINGS
- Use large enough hooks and large diameter shackles to avoid crushing
and kinking of the sling. If possible use Wide-Body shackles. They
increase the D/d ratio and you gain sling strength.
- Small diameter shackles reduce the sling strength and, most likely,
that small diameter shackle also has insufficient capacity for that job.
Shackle or not, objects to be lifted and all hook up points must at
least ensure a D/d Ratio of 5:1.
- Proper D/d ratio for the sling capacity. If the sling is too short
you may have to adjust the capacity because of the sling angle. The D/d
Ratio is the ratio of the diameter around which the sling is bent
divided by the body diameter of the sling.
BRAIDED WIRE ROPE BELT SLINGS
- A Grommet consists of an endless rope having construction 6/1
construction & is used where high ultimate breaking strength of the
rope is required beyond the limits of a single part rope.
- A strand of sufficient length to complete the Grommet shall be
obtained by either of the following methods:
Method A : An order strand shall be unlaid from a
specimen of 6/1 rope conforming to the requirement of the customer.
Method B :Unlaying from a specimen of 6/4 rope having
strands in all respects equipment to those obtained by method A above.
Method C : Using a virgin strand either prefromed or
post formed & in all other respects equivalent to those obtained by
method A & B.
- During the course of construction of a Grommet the performed lay of
the strand shall be maintained and shall not be interfered with, except
when laying in the core, for which purpose length of strand left to form
the core should be straightened .
- The length of the strand required to form a Grommet shall be equal to
about seven-and-a-half times the parameter of the Grommet.
Braided Belt Slings of Wire ropes are ideal for the lifting of the loads
which are abrasive, hot or may cut the other types of slings like polyester
webbing belt slings. Woven from tested quality high tensile wire ropes these
slings are very flexible, have wide surface to load contact. These can be
made in various length and width and safe working load capacity with both
soft eye and hard eye design. These are ideal for lifting of coils, hot
steel loads etc. these slings are made from 4 mm wire rope dia to 16 mm wire
rope dia and numbers of wires vary from 6 to 14 depending upon the specific
requirements of width and capacity. Generally made of 6x19 steel core
construction wire ropes.
