New ISO Standards lift the safety level of cranes worldwide

There is always a potential danger involved in the operation of cranes. New ISO Standards on crane inspections aim to reduce the risk of accidents to those people involved in a lifting operation and those in the vicinity, and to reduce the risk of damage to property.

Competency requirements for crane inspectors

Cranes – Competency requirements for crane inspectors, ISO 23814:2009, specifies the competency required of persons who carry out periodic, exceptional, alteration, and thorough inspections of cranes. It excludes the day-to-day inspection and checks performed by crane operators and maintenance personnel.

The objective of this international Standard is to achieve a uniformly high competency of crane inspectors worldwide. In some countries, there may be additional regulatory requirements that must also be taken into account.

The Standard addresses the following issues:

  • independence, impartiality, and integrity
  • technical knowledge and experience
  • techniques for crane inspection
  • training of crane inspectors.


Two other Standards point out that to ensure cranes are operated safely, their proper working and operational conditions need to be maintained. Therefore, all cranes are required to undergo inspections to detect deviations from safe conditions so they can be put right. The inspections are the responsibility of crane users or owners.

  • Cranes – Inspections – Part 1: General, ISO 9927-1:2009, specifies the inspections to be carried out on cranes, excluding inspections carried out prior to first use. It covers:
    • inspection
    • methods of inspection
    • inspection personnel
    • precautions for inspection
    • results of inspection.
  • Cranes – Inspections – Part 3: Tower cranes, ISO 9927-3:2005, specifies the regular inspections to be carried out on tower cranes. It covers:
    • daily inspections
    • frequent inspections
    • periodic inspections
    • thorough inspections.
