Overview

ISO 23814:2024 - Cranes - Competency requirements for crane inspectors defines the competency needed for persons who perform periodic, exceptional, and enhanced periodic inspections of cranes. Published as the second edition in 2024, the standard sets uniform competency criteria for crane inspectors while explicitly excluding checks carried out by crane operators and maintenance personnel. It emphasizes professional independence, impartiality and inspection integrity.

Key topics and requirements

The standard specifies required knowledge, experience and inspection techniques. Major technical topics include:

• Independence, impartiality and integrity
  • Avoidance of conflicts of interest that could compromise inspection outcomes.
• Technical knowledge (performance criteria in Annex B)
  • Structures and components: structural members, welds, corrosion limits, bolting and discard criteria.
  • Electrical systems: wiring diagrams, grounding, protection of enclosures and devices.
  • Mechanical components: gearboxes, drums, bearings, brakes, sheaves, ropes/chains and wear/discard criteria.
  • Hydraulic systems: circuits, pumps, hose and fluid specifications, leakage and filtration.
  • Internal combustion engines and lubrication systems: service, mounting, types of lubricants.
  • Assembly and operation: proper assembly, reeving and drum storage, safe access, cabs and controls, load chart interpretation.
  • Documentation: maintenance schedules, record keeping, manuals and hardware certifications.
  • Safety, rules and practices: applicable standards, site-specific rules, PPE and fall protection.
  • Tools and methods: inspection tools calibration, non‑destructive testing (visual, ultrasonic, magnetic particle, dye penetrant, etc.), and load test procedures.
• Experience requirements
  • Competency may be developed through training, apprenticeship and relevant hands‑on experience (design, manufacture, installation, maintenance or operation).
• Inspection techniques
  • Competency to inspect in accordance with the ISO 9927 series as applicable to the crane type.
• Recommended categories (Annex A)
  • Examples: tyre‑mounted mobile, crawler, tower, jib, bridge/gantry and other specific crane types.

Applications and users

ISO 23814:2024 is practical for:

• Crane inspectors seeking to demonstrate or benchmark competency.
• Employers and asset owners setting inspection staffing and qualification requirements.
• Certification and training providers designing competency assessments and curricula.
• Maintenance contractors and safety managers for recruitment and quality control of inspection services.
• Regulators and clients specifying inspection competence in procurement and compliance programs.

Using ISO 23814 helps improve inspection quality, reduce safety risk, and standardize expectations across international operations.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

This document was prepared by Technical Committee ISO/TC 96, Cranes, Subcommittee SC 5, Use, operation
and maintenance.
This second edition cancels and replaces the first edition (ISO 23814:2009), which has been technically
revised.
The main changes are as follows:
— in 4.2, technical knowledge to be possessed by crane inspectors has been revised;
— Clause 5 has been removed.
