ISO 9927-1:2013

Overview

ISO 9927-1:2013 – Cranes - Inspections - Part 1: General specifies the general requirements for inspection programs for cranes as defined in ISO 4306‑1. It defines inspection types, methods, personnel competence, record keeping and precautions needed to keep cranes in safe operational condition. This part establishes the baseline inspection framework; additional, crane‑type specific requirements are covered in other parts of the ISO 9927 series.

Key topics and technical requirements

• Scope and intent: Applies to all cranes covered by ISO 4306‑1 and sets general rules for maintaining safe working condition through inspections and testing.
• Inspection categories:
  • Daily inspection - visual and functional checks before each shift (can be performed by the operator).
  • Frequent inspection - service inspections aligned with routine servicing (normally at intervals not exceeding three months, depending on use and environment).
  • Periodic inspection - comprehensive program with intervals not exceeding 12 months for cranes in service; includes documentation review and written reporting.
  • Enhanced periodic inspection - optional, recommended after five years of service as an alternative to a major inspection regime.
  • Exceptional inspection - after incidents (e.g., overload, collision, fire, extreme weather) or after repairs/changes affecting load-bearing components.
  • Major inspection - special assessment required when enhanced regime is not used or for re‑commissioned/imported cranes lacking continuous records; includes inspection of critical components and possible strip‑down.
• Methods of inspection: Visual examination, non‑destructive testing (NDT), functional tests, no‑load and load tests, static, dynamic and stability tests.
• Personnel and competence: Inspections must be performed by a competent person (Annex D); competence requirements align with ISO 23814.
• Precautions, repairs and records: Safety issues must be resolved before crane use. The standard requires logbooks, inspection records and retention of written reports (Clause 10). User organization instructions must incorporate manufacturer instructions and be assessed by a competent person.

Practical applications - who uses ISO 9927-1

• Crane operators and site supervisors (daily and frequent checks)
• Maintenance teams and service providers (periodic, enhanced and major inspections)
• Safety managers and occupational health & safety staff (program development, compliance)
• Inspectors and certification bodies (assessment, reporting)
• Equipment purchasers and fleet managers (procurement, re‑commissioning, import checks)

ISO 9927-1 is used to structure crane inspection programs, develop checklists and logbooks, define inspection frequency based on use/environment, and determine when NDT or load testing is required.
