Is safe working load same as working load limit?

Working Load Limit used for replacing Safe Working Load

Both of these two terminologies are used for industry as load limit terminology when evaluating the maximum force allowable during lifting or holding. Because of numerous environmental factors, manufacturers no longer find the term "Safe Working Load" accurately descriptive for maximum rated loads in equipment standards.

Manufacturers all over the globe are concerned with effectively assigning load limits to avoid "plastic deformation" or stress effects during continued use of rigging equipment. These limits do not infer safety because so many factors can affect equipment with use in various environmental heat, cold and wet extremes over time.
