Study Notes

Industry Relevant Definitions

Minimum Breaking (or Failure) Load: The specified load (mass or force) below which the equipment does not fail.
Multipurpose Equipment: Designed to a standard specification for various loads, not one specific lifting application.
Operative: A trained person using the equipment.
Rated Capacity: The maximum gross load a lifting appliance can lift in any configuration.
Proof or Test Load: The load (mass or force) applied by a Competent Person for testing.
Single Purpose Equipment: Designed and dedicated for lifting a specific load and environment.
Report of Test: A report issued by a competent person detailing the test specifics (previously known as test certificate); not a legal document allowing use, except when used with legal documents.

Verification

Verification: A generic term for procedures confirming lifting equipment adheres to the required standard, specifications, legal requirements, and is safe to operate. Includes proof load tests, sample break tests, non-destructive tests, calculation, measurement, and thorough examination.

Verification – New Equipment

For new equipment, the verification methods (dependent on the standard for materials) may differ from proof load testing in certain cases.
Some items, built from parts verified to their own standards, may require no further tests.

Report of a Thorough Examination

A report of a thorough examination details any defects found, or a statement that the item is fit for further use. If a test was part of the examination, test details are also included.
The report must be kept with the lifting equipment records. There may be an appendix with the test report.

Safe (Specific Application) Working Load (SWL)

SWL is the maximum load a lifting equipment can lift (lower or suspend) in the specific job conditions.
SWL is marked on the equipment.
SWL is the same value as the working load limit (WLL) or rated capacity in some cases, but may be less.

Working Load Limit (WLL)

WLL is the maximum load a lifting equipment is designed to raise, lower, or suspend.
In some standards, WLL is referred to as maximum SWL.
WLL is more commonly used for lifting accessories, but rated capacity is now common for lifting appliances.

WLL vs SWL

There's confusion between SWL, working load limit, and rated capacity.
Working load limit or rated capacity is the maximum SWL under ideal conditions (calculated).
The Competent Person may reduce the SWL depending on the use conditions.

Risk Assessment

Assessing and managing risks, with a focus on human harm, legal effects, and economic consequences.
Risk assessment involves identifying hazards, deciding who could be harmed, evaluating risks, determining precautions, recording findings, and reviewing the assessment for necessary changes.

Identifying People at Risk

Identifying all people who may be affected by the activity, not just those directly involved. This includes workers in the vicinity, bystanders, and members of the public.

Controlling Risks

The 3 primary reasons for assessing and managing risk are human harm, legal effects, and economic effects.

Probability and Severity

Probability is the likelihood of harm from a hazard.
Severity is the potential consequences if harm does occur.
Risk is the combined likelihood and severity of a hazard.

Materials Commonly Used in Lifting Equipment

Lifting equipment materials are typically grouped into Metals, Polymers, and Natural Products.

Steel Grades

Steel grade numbers (4, 6, 8, 10, 12) relate to breaking strength.

Strain Age Embrittlement

Strain age embrittlement is a form of brittleness caused by overstrained steel (resting in warm conditions).
