IMPORTANT
SAFETY WARNINGS
It
is of the utmost importance that anyone purchasing from this website
read and understand all warnings and other information listed below
and/or adjacent to the product description.
All products
are sold with the express understanding that the purchaser is
thoroughly familiar with the correct application and safe use.
Use all products properly, in a safe manner and for the application
for which they were intended. allwayinc.com assumes no responsibility
for the use or misapplication of any product sold. Responsibility
for design and use decisions rests with the user.
REMEMBER:
Any product will break if abused, misused or overused. Any well-designed
and well-built product can become hazardous in the hands of a
careless user.
It would be
impossible in the text of this website to list all possible dangers
and misapplications associated with the use of all products contained
herein. However, in order to promote safe rigging habits, the
most common hazards associated with the use of these products
are outlined. Therefore:
Never
exceed the Work Load Limit.
Match
components properly.
Keep
out from under a raised load.
Avoid
shock loads.
Inspect
products regularly.
WORK
LOAD LIMIT
Never
exceed the Work Load Limit (WLL) Rated Capacity. The Work Load
LImit is the maximum load which should ever be applied to the
product, even when the product is new and when the load is uniformly
applied straight line pull only. Avoid side loading. All
web-site catalog ratings are based upon usual environmental conditions,
and consideration must be given to unusual conditions such as
extreme high or low temperatures, chemical solutions or vapors,
prolonged immersion in salt water, etc. Such conditions or high-risk
applications may necessitate reducing the Work Load Limit. Work
Load Limit will not apply if product has been welded or otherwise
modified.
Matching
of Components
Components must match. Make certain that components such as
hooks, links or shackles, etc. used with wire rope (or chain or
cordage) are of suitable material and strength to provide adequate
safety protection. Attachments must be properly installed and
must have a Work Load Limit at least equal to the product with
which they are used.
Raised
Loads
Keep out from under a raised load. Take notice of the recommendation
from the National Safety Council Accident Prevention Manual concerning
all lifting operations:
"All
employees working on cranes or hoists or assisting in hooking
or arranging a load should be instructed to keep out from under
the load. >From a safely standpoint, one factor is paramount.
Conduct all lifting operations in such a manner, that if there
were on equipment failure, no personnel would be injured. This
means keep out from under a raised load and keep out of the line
of force of any load."
Shock Loads
Avoid impacting, jerking or swinging of load -- Work Load Limit
will not apply. A shock load is generally significantly greater
than the static load. Avoid shock loads.
REGULAR
INSPECTIONS
Inspect products regularly for visible damage, cracks, wear, elongation,
rust, etc. Protect all products from corrosion. The need for periodic
inspections cannot be overemphasized. No product can keep operating
at rated capacity indefinitely. Periodic inspections help determine
when to replace a product and reduce rigging hazards. Keep inspection
records to help pinpoint problems and to insure periodic inspection
intervals.
Due to the
diversity of the products involved and uses to which they can
be put, it would be counter-productive to make blanket recommendations
for inspection procedures and frequency. Best results will be
achieved when qualified personnel base their decisions on information
from rigging and engineering manuals and on experience from actual
use in the field. Refer to sources listed below for technical
literature.
Frequency
of inspection will depend on environmental conditions, application,
storage of product prior to use, frequency of use, whether or
not life, limb or valuable properly are at risk, etc. When in
doubt, inspect product prior to each use. Carefully check each
item to be inspected for wear, deformation, cracks or elongation-signs
of imminent failure. Immediately withdraw such items from service.
Rust damage
is another potential hazard. When in doubt about the extent of
corrosion or other damage, withdraw the items from service. Destroy,
rather than discard, items that have been judged defective. They
might be used again by someone not aware of the hazard of the
defect.
DEFINITIONS
Information
contained in this catalog is subject to change; all weights and
dimensions are approximate. Ratings are stated in short tons (2,000
lbs.) or pounds. All dimensions are in inches; all weights are
in pounds.
Proof Test
Load (Proof Load)
The term "Proof Test" designates a quality control
test applied to the product for the sole purpose of detecting
defects in material or manufacture. The Proof Test Load (usually
twice the Work Load Limit) is the load which product withstood
without deformation when new and under laboratory lest conditions.
A constantly increasing force is applied in direct line to the
product at a uniform rate of speed on a standard pull testing
machine.
Breaking
Strength/Ultimate Strength
Do not use breaking strengths as a criterion for service or
design purposes. Refer to the Work Load Limit.
Breaking Strength
is the average force at which the product, in the condition it
would leave the factory, has been found by representative testing
to break, when a constantly increasing force is applied in direct
line to the product at a uniform rate of speed on a standard pull-testing
machine.
REMEMBER:
Breaking Strengths, when published, were obtained under laboratory
conditions that are almost always impossible to duplicate in actual
use.
Design Factor
(sometimes referred to as safety factor) An industry term denoting
theoretical reserve capability. Usually computed by dividing the
catalog Breaking Strength by the catalog Work Load Limit and generally
expressed as a ratio. For example: 5 to 1.
