WIRE ROPE AND SLING BASICS
Wire rope slings are both 昀氀exible and resistant to
abrasion. These characteristics are determined by the
rope construction. Fewer wires result in larger diameter
wires, better abrasion resistance, and reduced 昀氀exibility.
More wires result in decreased wire diameter, reduced
abrasion resistance, increased 昀氀exibility, and kink
resistance.
Wire Rope Construction
Wire rope products may be proof tested upon request. If
they contain swaged terminations and will be used as a
sling, they will be 100% proof tested.
The scale below shows the relative position of the sling
constructions shown in this catalog as they pertain to
abrasion resistance and 昀氀exibility.

WIRE ROPE SLINGS
Features and Bene昀椀ts
• Tu昀昀-Tag™ for capacity and serial numbered
identi昀椀cation for traceability and compliance with
OSHA.
•
•
Least expensive (per capacity), of all steel slings.
•
Countless combinations of sling terminations: hooks,
chokers, and thimbles are available to 昀椀t speci昀椀c lift
requirements.
Use of IWRC EIPS rope gives 15% greater capacity
than IWRC IP (Improved Plow) ropes.
D/d - Basket Hitch E昀昀ect
Tests have shown that when a sling
body is bent around a diameter, the
strength of the sling is decreased.
D/d ratio is the ratio of the diameter
around which the sling is bent,
divided by the body diameter of the
sling.
The capacities in this catalog are based on the
minimum D/d ratios that appear below each of the
capacity tables. For more severe bending conditions,
contact Lift-All for revised capacities.
Environmental Considerations
• IWRC must not be used at temperatures above
400°F.
•
FC must not be used at temperatures above
180°F.
•
Fiber core ropes should not be subjected to
degreasing solvents.
E昀昀ect of Shackle Pin or Crane Hook on Sling Eye
Damage to slings can occur if the
wrong size pin or hook is used. The
width of the hook should never exceed
the natural inside width of the eye.
The eye dimension for each type
and size of the slings are shown in
the capacity tables of this catalog. If
your pin or hook is large, request an
oversized eye.
