Definitions and Warnings

The maximum recommended load that should be exerted on the item.
The following terms are also used for the term Rated Load: “SWL,” “Safe
Working Load,” “Working Load,” “Working Load Limit,” and the “Resultant
Safe Working Load.” All rated load values, unless noted otherwise, are for
in-line pull with respect to the centerline of the item.

The average load to which an item may be subjected before visual
deformation occurs or a load that is applied in the performance of a
proof test.

A term designating a tensile test applied to the item for the sole purpose
of detecting injurious defects in the material or manufacture.

The average load at which the item is being tested fails or no longer
supports the load.

A resulting load from the rapid change of movement, such as impacting
or jerking, of a static load. A Shock Load is generally significantly
greater than the static load.

An industry term denoting theoretical reserve capability. Usually computed
dividing the catalog stated ultimate load by the catalog stated working
load limit and generally expressed as a ratio, for example 5 to 1.

CAUTIONS OR WARNINGS

All ratings shown in this literature are based upon the items being new or “in as new” condition.Catalog ratings are considered to be the greatest load that should be applied to the item; therefore, any shock loading must be considered when selecting the item for use in a system.

 
The products shown in this literature are subject to wear, misuse,overloading, corrosion, deformation,intentional alteration and other usage factors which may necessitate a reduction in the products Rated Capacity or a reduction in its Design Factor. Therefore, it is recommended that all products be regularly inspected to determine their condition as a basis for deciding if the product may continue to be used at the catalog assigned. WL, a reduced WL, a reduced design factor, or removed from service.
