Study Notes

Industry Relevant Definitions

  • Minimum Breaking (or Failure) Load: The specified load (mass or force) below which the equipment fails by fracture or distortion.
  • Multipurpose Equipment: Designed to a standard specification for multiple lifting loads, not one specific application.
  • Operative: Trained person operating the equipment.
  • Rated Capacity: Maximum gross load the lifting appliance can lift in a given configuration.
  • Proof or Test Load: A load (mass or force) applied to test the equipment by a Competent Person.
  • Single Purpose Equipment: Dedicated to lifting a specific load in a precise manner and environment.
  • Report of Test: A report issued by a competent person documenting test specifics and details. This isn't a legal document for use, except when supporting legal documents like EC Declaration of Conformity or Manufacturer's Certificate.

Verification

  • Verification: A process ensuring lifting equipment meets legal requirements and specifications. This includes methods like proof load tests, sample break tests and more. It's a generic term to describe manufacturer or competent person methods to guarantee safe operation.
  • New Equipment Verification: Depends on the standard the equipment is designed based on. Some equipment isn't suitable for proof load testing due to materials, while other components may be verified independently and just need assembly verification.

Report of Thorough Examination

  • A report of a thorough examination (or periodic inspection) is issued by a Competent Person. It documents findings, defects, or statements of fitness for continued use.
  • The report may contain details of any tests involved in the examination.
  • Key Notes: The report must be kept as part of equipment records. In some cases, the test report will be an appendix.

Safe (Specific application) Working Load (SWL)

  • Safe Working Load (SWL) or Specific Application Load (SWL): The maximum load determined by the Competent Person for a lifting item under specific service conditions.
  • The SWL is generally equal to the working load limit (WLL) or rated capacity.
  • The SWL may be less than the WLL in some circumstances regarding usage conditions.
