Major Inspection — Engineering-Driven & AS 2550 Compliant

All crane structures are generally designed for 25 years of service life, and mechanical components for 10 years — but these design periods depend heavily on how often the crane is used and the loads it regularly lifts.

​

At Levitate Lifting, our major inspection process is fully aligned with AS 2550 and is built around engineering analysis, accurate usage data, and targeted inspections. Our goal is to verify safety and compliance while minimising unnecessary disassembly and downtime

When is a Major Inspection Required?

A major inspection is required when:

  • The crane’s usage exceeds its designed duty classification.

  • The crane is relocated or taken into operation as a second-hand unit with no reliable service history.

  • The equipment has reached its Design Working Period (DWP).

  • It is unclear whether the equipment has reached its DWP.

  • The equipment has no certification or installation date recorded.

Design Working Period (DWP) Assessment

The first step is to calculate the remaining DWP based on reliable usage data. If this calculation shows the crane or hoist will reach a design limit before the next scheduled periodic inspection, a major assessment is required.

​

This evidence-based approach ensures that major inspections are carried out when needed — not simply by the calendar.

Our Major Inspection Process

We follow a clear, structured sequence to ensure thoroughness and transparency:

  1. History & Usage Review

    • Collect logbooks, inspection reports, and usage data.

  2. Design Working Period (DWP) Calculation

    • Engineering analysis to determine remaining service life.

  3. Visual Inspection & Non-Destructive Testing (NDT)

    • Identify signs of wear, cracking, corrosion, or fatigue.

  4. Decision Point — Is disassembly needed?

    • If the condition of a component can be confirmed without opening it, we keep it in service.

    • If internal assessment is essential, targeted disassembly is carried out.

  5. Repair or Replacement

    • Any defective or worn components are addressed as required.

  6. Compliance Certification & Documentation

    • A detailed inspection report, compliance certificate, and remnant life estimate are provided.

What to expect after the completion of Major Inspection?

  1. Inspection Report: The inspection will be conducted by a qualified and certified inspector who will provide a detailed inspection report. This report will outline the findings of the inspection, including any deficiencies or issues identified during the inspection.

  2. Compliance with Standards: The inspection will assess whether the equipment complies with the relevant Australian standards, including AS2550. If any non-compliance issues are identified, they will be documented in the inspection report.

  3. Safety Recommendations: If any safety concerns are identified during the inspection, the inspector may provide recommendations for addressing these concerns. These recommendations may include repairs, maintenance, or modifications to the equipment to ensure it meets safety standards.

  4. Compliance Certification: If the equipment passes the inspection and meets all safety and compliance requirements, the inspector may issue a compliance certification. This certification indicates that the equipment is safe to use and complies with AS2550.

  5. Deficiency Remediation: If the inspection identifies deficiencies or non-compliance issues, the client will typically be responsible for addressing these issues. This may involve repairing or replacing components, conducting maintenance, or making modifications to the equipment as recommended by the inspector.

  6. Follow-up Inspections: Depending on the findings of the major inspection and the age and condition of the equipment, the inspector may recommend a schedule for follow-up inspections to ensure ongoing safety and compliance.

  7. Remnant Life Estimate: It's essential to keep all inspection reports and certifications on record for compliance and liability purposes. Clients should maintain a record of all major inspections, compliance certificates, and any maintenance or repairs performed on the equipment.
