New ISO Standards on crane inspections to lift the safety level of cranes worldwide


Newly published International Organization for Standardization (ISO) Standards on crane inspections aim to reduce the potential danger involved in the operation of cranes, 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. 

These ISO Standards, and related cranes Standards referenced in the Department of Labour Approved Code of Practice for Cranes, are available from Standards New Zealand.

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. The Standard aims 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.

Crane inspections

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, and 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, and thorough inspections.
