What an annual inspection actually is
The annual crane inspection sits in the middle of a layered inspection regime defined by AS 2550. Each layer catches different things:
- Pre-start (every shift) — operator visual check before use; takes minutes
- Routine (monthly to quarterly) — maintenance contractor checks ropes, brakes, lubrication; takes hours
- Annual — competent-person inspection focused on safety verification; takes a half-day to full day
- Major (10-yearly) — deep structural and mechanical assessment by an engineer; takes 1-3 days
The annual inspection is the most overlooked layer. Many facilities run their routine maintenance and assume that covers them — but routine maintenance is the contractor's hands on the crane fixing things, and that's a different activity from an independent inspection assessing whether the crane is safe to keep operating. The two activities can be done by the same firm but should be separately scoped, separately reported, and separately billed.
The legal framework
Annual inspection sits within the same legal stack as the major inspection — WHS Regulations (state-based) require crane inspection per the manufacturer's recommendations and applicable Australian Standards. AS 2550.1 sets the core requirement. Your insurer almost certainly assumes annual inspections are happening; if they're not, your cover may be void in the event of an incident.
For most cranes, annual inspection is the minimum interval. Higher-duty cranes — those running closer to rated capacity, or with high lift cycles — typically need more frequent inspection per the manufacturer's recommendation or your duty-class calculation. A continuously-running steel mill crane or a foundry crane will be inspected six-monthly or quarterly, not annually.
What gets inspected
A complete annual inspection covers four domains:
Visual structural inspection
- Main girder, end carriages, runway visible from below
- Visible welded connections — cracking, corrosion, deformation
- Bolt connections and safety pins
- Bumper buffers and end-of-travel stops
- Operator cabin (if fitted) — controls, seat, visibility
Mechanical inspection
- Wheel condition — flange wear, tread, rotation
- Brake function and lining wear
- Hoist drum — rope grooves, side flange condition
- Hook — throat opening measurement, freedom of rotation, locking device
- Wire rope per AS 2759 — broken wires, diameter reduction, lubrication
- Chain (for chain hoists) — elongation, surface condition
- Trolley and bridge travel — function, alignment, drag
Electrical and control inspection
- Pendant or remote function — every button, every direction
- Upper and lower hoist limits
- Bridge and trolley end-of-travel limits
- Emergency stop function from every control point
- Main isolator operation
- Overload protection device test
- Earth bond visual check
Documentation review
- Maintenance log since last inspection
- Pre-start checklists kept by operators
- Previous inspection report and rectification register
- Modification register
Who can perform an annual inspection
AS 2550 requires the inspection to be performed by a "competent person" — someone with the training, experience and knowledge to detect defects and assess risks. For annual inspections this is typically:
- A qualified crane technician with manufacturer training
- A mechanical fitter with crane-specific experience
- A chartered mechanical engineer
- A specialist crane inspection company employing the above
Annual inspection doesn't require a chartered engineer in the way the major inspection does — the 10-yearly inspection is more demanding because it includes residual-life calculation and NDT interpretation. But the inspector should still be independent of day-to-day operation of the specific crane to ensure objective assessment.
What it costs
Indicative ranges across the Australian market — annual crane inspections typically run $400-$1,200 per crane depending on size, location and access requirements:
| Small jib or workstation crane (under 2 t) | $400 – $700 |
| Single-girder EOT bridge crane (2 – 10 t) | $600 – $1,000 |
| Double-girder EOT bridge crane (10 – 50 t) | $900 – $1,500 |
| Large gantry, portal or specialised crane (50 t+) | $1,200+ |
| EWP / scaffold access (additional) | $300 – $1,000 |
| Multi-crane facility discount | typically 15-25% per additional crane |
The biggest cost variable is access. A jib crane on a shop floor at 4 m height can be inspected from a stepladder. A 30-tonne EOT bridge crane on a 12 m runway needs an EWP or scaffold and the access can cost more than the inspection itself. Plan ahead: schedule annual inspections to coincide with shutdowns or maintenance windows, and have access equipment ready. We quote each inspection on actual scope — send through the basics for a fixed-price quote, usually within one business day.
What happens if defects are found
The inspector's report categorises findings into three tiers:
- Information — observations, no action required
- Defect requiring rectification — must be addressed within a specified timeframe (often 7-30 days), but the crane can continue operating in the interim, sometimes at reduced capacity or with operational restrictions
- Defect — out of service — safety-critical defect requiring the crane to be locked out immediately until rectified. Examples: failed brake, cracked structural weld, failed limit switch, damaged hook
The most common annual-inspection findings:
- Worn brake linings approaching replacement threshold
- Wire rope showing elevated wire breaks or diameter reduction
- Hook throat opening exceeding wear limit
- Limit switches drifting out of calibration
- Pre-start checklists not being completed or filed
- Documentation gaps — modifications not formally engineered, missing service records
How to prepare for an annual inspection
You can keep annual inspection cost down and avoid surprises with a few simple practices:
- Keep your maintenance log up to date — the inspector will ask for it
- Have pre-start checklists filed — these prove the crane has been inspected daily, satisfies WHS audit requirements
- File previous inspection reports — the inspector wants to see findings have been actioned
- Schedule access — book the EWP or scaffold to be on site for the inspection day
- Have the crane available — out of production for the full inspection window, not "we'll need it for an hour at lunch"
- Tell the inspector about known issues — they'll find them anyway, disclosure builds trust
Annual inspection vs routine maintenance — same firm or different?
You can use the same firm for both, but the activities should be separately scoped and reported. There's a real conflict of interest risk if the contractor maintaining the crane is also assessing whether their own work is adequate. Best practice for facilities with safety-critical or high-duty cranes is to use a different inspector from the maintainer. For lower-duty cranes a single trusted contractor handling both is workable, provided the inspection report is genuinely independent.
The 10-yearly major inspection should always be done by an independent engineer — that's the right intervention point for an outside view.

Frequently asked questions
How often should a crane be inspected?
AS 2550 sets out a layered inspection regime: pre-start checks every shift by the operator, routine inspections monthly to quarterly by maintenance staff, an annual inspection by a competent person, and a major inspection at least every 10 years. High-duty cranes typically need annual inspection more frequently. Your manufacturer's manual and the crane's duty class determine the exact interval.
What is checked in an annual crane inspection?
An annual inspection covers visual structural inspection of the bridge, runway and end carriages; mechanical wear checks on wheels, brakes, drum, hook and rope; functional testing of all controls including limit switches and overload protection; electrical safety check including emergency stop and isolator; documentation review; and a written report identifying any defects requiring rectification.
Who can perform an annual crane inspection?
AS 2550 requires inspections by a "competent person" — typically a qualified crane technician, mechanical fitter with crane experience, or chartered engineer. The competent person must be independent of day-to-day operation of the crane to ensure objective assessment.
How much does an annual crane inspection cost in Australia?
Annual crane inspections typically cost $400-$1,200 per crane depending on size, location and access requirements. Small jib and workstation cranes sit at the lower end; larger EOT bridge cranes and gantry cranes at the higher end. Travel and access costs can add to this.
What's the difference between annual inspection and routine maintenance?
Routine maintenance is your maintenance contractor's hands on the crane fixing things — typically monthly or quarterly — focused on lubrication, adjustment and replacement of consumable items. Annual inspection is a separate compliance activity by a competent person focused on safety verification and defect detection. The same contractor can perform both, but the inspection report should clearly distinguish between findings and rectifications.
