WHS Duties of Crane Owners and Operators: PCBU and Plant Obligations

The model WHS Act frames obligations around the person conducting a business or undertaking, or PCBU. A PCBU is the entity operating the business, whether that is a company, partnership or sole trader. If your business owns, hires out, leases or operates cranes, you are a PCBU with a primary duty of care to ensure health and safety so far as is reasonably practicable.

That duty is broad and cannot be contracted away. Even if you hire a crane with an operator, you still hold duties toward your own workers and anyone affected by the work. Regulators including SafeWork NSW, WorkSafe VIC and Workplace Health and Safety Queensland consistently emphasise that multiple PCBUs can hold overlapping duties on the same site, and each must consult, cooperate and coordinate with the others.

Officers of a PCBU — directors and senior managers — carry a separate due diligence duty. They must take reasonable steps to understand the crane hazards in the business, ensure resources are available for safe operation, and verify that risk controls are actually being used.

The WHS Regulations contain a dedicated plant chapter that applies directly to cranes. It requires that plant is inspected and maintained so it remains without risks to health and safety, that maintenance and inspection are carried out by a competent person, and that records are kept. Registered plant designs and items — which include many cranes and tower cranes — carry additional registration duties.

The regulations also assign duties by role across the supply chain. Designers, manufacturers, importers and suppliers of cranes each have obligations to ensure the plant is safe and to pass on information about safe use. When you buy or hire a crane, you are entitled to that information, and you should retain it as part of your compliance file.

High risk work licensing sits alongside the plant duties. Operating many cranes requires a licence, and the PCBU must not direct or allow an unlicensed person to perform that work. Verifying licences before work starts is a simple but essential control.

• Inspect and maintain cranes using a competent person
• Keep inspection and maintenance records available for review
• Register plant and plant designs where required
• Verify high risk work licences before operation
• Consult, cooperate and coordinate with other PCBUs on site

Operators are workers under the WHS Act and hold their own duties. They must take reasonable care for their own safety and that of others, follow reasonable instructions and use plant in accordance with training and procedures. In crane work, that means completing pre-operational checks, respecting rated capacities, observing exclusion zones and reporting defects immediately.

The operator is often the first line of defence against a developing fault. A worn wire rope, a sluggish hydraulic function or an unusual noise is most likely to be noticed from the cab. WHS duties therefore include a genuine expectation that operators are trained to recognise these warning signs and empowered to stop work when something is wrong, without fear of penalty.

Meeting these duties reliably requires a system rather than good intentions. A workable crane compliance system defines who carries out daily, routine and periodic inspections, at what frequency, and to which standard. It schedules the major inspection at ten years of service in line with AS 2550, tracks high risk work licences and captures every inspection outcome in a retrievable record.

The strongest systems tie each task back to a named responsible person and a due date, so nothing is missed when staff change or workloads spike. When a regulator visits, a well-run system produces the evidence within minutes rather than triggering a scramble through paperwork. That readiness is itself a demonstration of due diligence.

Regulators have graduated enforcement tools, from improvement and prohibition notices through to prosecution. A prohibition notice can shut a crane down on the spot if an inspector believes there is a serious risk, halting a job and its revenue immediately. Where a duty holder fails to comply, penalties can be significant and, for the most serious breaches, extend to individuals as well as the business.

Beyond legal exposure, a crane incident carries real human cost and reputational damage that outlasts any fine. The most effective protection is not a document trail alone but a culture where inspection, maintenance and competency are treated as non-negotiable. Fulfilling your WHS duties is ultimately about sending everyone home safely at the end of the shift.

Cranes Australia helps PCBUs meet their plant duties with independent inspections, load testing and clear documentation that stands up to regulator review. We work with owners, hire companies and operators to build inspection schedules that match how your cranes are actually used, and we flag defects before they become notices.
