ISO 9927-5:2017

Overview

ISO 9927-5:2017 - "Cranes - Inspections - Part 5: Bridge and gantry cranes, including portal and semi-portal cranes and their supporting structures" specifies required inspections for bridge and gantry cranes and their supporting structures. Intended to be used together with ISO 9927‑1, it defines inspection types (daily, frequent, periodic and exceptional), recordkeeping, and the roles of the competent person responsible for inspection. It does not cover pre‑use (first‑use) inspection.

Key topics and requirements

• Inspection types
  • Daily inspections: carried out at the start of each shift to test functionality and visually check for defects (no dismantling normally required).
  • Frequent inspections: more detailed visual, auditory and functional tests (generally no dismantling); maximum interval typically up to 6 months unless extended by a competent review.
  • Periodic inspections: visual and functional tests with and without rated load; scheduled at defined intervals and carried out by a competent person using historical records and any registered automatic data.
  • Exceptional inspections: provisions exist for inspections triggered by unusual events (see Clause 8).
• Core inspection items (examples specified in the standard)
  • Wire ropes, chains and belts (damage, wear, see ISO 4309 for wire rope guidance)
  • Hooks, safety latches and terminations
  • Sheaves, bushes, pins and retaining devices
  • Crane structure (deformation, cracked welds, loose fasteners)
  • Wheels, wheel flanges and guide roller systems
  • Brakes, load limiters and motion‑limiting devices
  • Electrical equipment and power feed systems (insulation resistance check)
  • Rails, end stops, buffers, guards and signage (rated capacities, operator controls)
• Records and reporting
  • Written records required for daily, frequent and periodic inspections (identity, date, inspector, results, actions taken).
  • Manufacturer’s inspection instructions take precedence where applicable.
• Competence
  • Inspections must be performed by a competent person with practical and theoretical knowledge of the crane and lifting operations.

Applications and users

Who uses ISO 9927-5:2017:

• Crane operators and shift personnel (daily checks)
• Maintenance technicians and inspection teams (frequent/periodic inspections)
• Safety managers, plant managers and asset custodians (inspection scheduling, recordkeeping)
• Third‑party inspectors and regulatory authorities verifying compliance Practical uses include developing inspection checklists, preventive maintenance schedules, compliance documentation, and safety programs for industrial facilities with bridge or gantry crane installations.
