(WLL)
is one-third
(1/3) of the break strength.
EXAMPLE:
15,000 lbs
(Break Strength) / 3
= 5,000 lbs. (WLL) |

The
basic rule, to ensure safety, is a 3 to 1 ratio be
used on any item moving in any direction where brakes
are being applied and G-forces occur. It is the responsibility
of the user to determine the number of straps needed
to secure his load safely based on the SWL rule to
the right.
NOTE:
All tie-down straps, 5000 lb. & up come
with a label showing size, maximum load and
W.L.L. (working load limit). Remember the
W.L.L.. is 1/3 of the maximum load. Always use
the W.L.L. when selecting tie-downs. Example:
A box weighing 3300 lbs., you would use (2)
straps with a 5000 lb. max. load limit. The
safe work load for a 5000 lb. strap is 1650
lbs.
