Product Overview

Summary: This Safe Operating Procedure sets out a clear, step-by-step process for inspecting crane hooks and safety latches before and during lifting operations. It helps Australian workplaces prevent dropped loads, equipment failure and serious injuries by standardising inspections in line with WHS duties and relevant Australian Standards.

Crane hooks and their associated safety latches are critical components in any lifting operation. A worn, damaged or incorrectly functioning hook or latch can quickly lead to a lost load, serious property damage or life‑changing injuries. This Hook and Latch Inspection in Cranes Safe Operating Procedure provides a practical, repeatable method for verifying that hooks and latches are fit for purpose before they are put under load, and that defects are identified and managed before they become incidents.

Tailored for Australian workplaces, this SOP supports compliance with WHS legislation and relevant Australian Standards by clearly defining inspection criteria, rejection limits, tagging requirements and reporting processes. It removes ambiguity for operators and supervisors by outlining exactly what to look for—such as throat opening, deformation, corrosion, latch alignment and spring tension—and what to do if a defect is found. By implementing this procedure, businesses can demonstrate due diligence, improve the reliability of lifting operations, and create a consistent standard across multiple sites, contractors and shifts.

Key Benefits

• Reduce the risk of dropped loads, near misses and serious injuries through consistent pre-use hook and latch inspections.
• Ensure compliance with Australian WHS legislation and lifting equipment standards by documenting clear inspection and rejection criteria.
• Standardise inspection practices across operators, shifts and sites, improving reliability and accountability in crane operations.
• Streamline defect reporting, lock‑out and tagging processes so unsafe hooks and latches are quickly removed from service.
• Support more effective training and competency assessment for crane operators, doggers and riggers using a clear, practical procedure.
