MISTAKES PEOPLE MAKE BUYING A USED CRANE
A used crane can be a smart purchase or an expensive mistake, and the difference usually comes down to what the buyer checked before the money changed hands. A crane that looks tidy in a yard can be carrying fatigue cracks, an overdue major inspection or a history the seller would rather not discuss.
Unlike a second-hand vehicle, a crane comes with ongoing legal obligations. Once it is yours, you are responsible for keeping it compliant, inspected and safe to use, and any problem the previous owner left behind becomes your problem. The purchase price is only part of the cost.
This guide covers the mistakes that catch buyers out, what they end up costing, and how an independent inspection before purchase turns a gamble into an informed decision.
1.Buying without an independent pre-purchase inspection
Buyers rely on the seller's word, a quick walk-around, or the fact that the crane starts and moves. Structural fatigue, worn slew rings, cracked welds and worn ropes are not visible from the seat, and a crane can operate right up until something fails. People have bought cranes that needed tens of thousands in repairs before they were legally safe to use.
How a professional handles it: An independent inspection by a qualified crane inspector, carried out before purchase, assesses the crane's real condition against AS 2550 and AS 1418. It gives you a clear picture of what you are actually buying and what it will cost to make good.
2.Ignoring the service and inspection history
The logbook is missing, incomplete, or nobody asks for it. Without records you cannot tell whether the crane has been maintained, whether it has been overloaded, or what repairs it has had. A crane with no history is a crane with no proof it was ever looked after, and that gap follows the machine for its whole life.
How a professional handles it: A complete logbook and maintenance history should be reviewed before purchase and handed over on sale. An inspector can read that history and flag anything that does not add up or is missing entirely.
3.Overlooking an overdue major inspection
Buyers do not check where the crane sits in its major inspection cycle. Many cranes require a major inspection at defined intervals, and one that is due or overdue can add a very large, non-negotiable cost immediately after purchase. A crane cannot lawfully be used past its inspection date, so an overdue machine may sit idle until the work is done.
How a professional handles it: The crane's design life and major inspection status are confirmed before you buy, so the cost and timing are built into your decision. A qualified inspector can tell you exactly where the crane sits in its cycle under AS 2550.
4.Assuming the load chart and capacity suit your work
The crane is bought on tonnage alone without checking whether its chart, reach and configuration match the lifts you actually do. Capacity falls away sharply with radius, and a crane that suits one operation may be useless for another. Buyers regularly end up with a machine that cannot safely perform the very lifts they bought it for.
How a professional handles it: Match the crane's full load chart to your real lifting profile before committing, not just its headline rating. An engineer can review your typical lifts against the chart so the crane genuinely fits the work.
5.Missing structural and fatigue damage
Fresh paint, filler and cosmetic tidying can hide cracks, corrosion and past repairs in the boom, chassis and load-bearing structure. Structural fatigue is cumulative and can lead to catastrophic failure under load. A repaint over a crack does not fix the crack, it just hides the warning sign.
How a professional handles it: A thorough structural assessment, including non-destructive testing where warranted, checks the parts that actually carry the load. This is standard in a proper pre-purchase inspection and reveals damage that paint conceals.
6.Not verifying safe working load devices and limiters
The rated capacity limiter, load moment indicator and safety cut-outs are assumed to work because the crane runs. These devices are what stop an overload, and if they are bypassed, faulty or disabled the crane will happily lift itself into a rollover. Buyers have discovered too late that safety systems were disconnected by a previous owner.
How a professional handles it: All load-limiting and safety devices are tested and confirmed functional as part of the inspection. A qualified inspector verifies they operate correctly and have not been overridden.
7.Skipping a load test before relying on the crane
The buyer takes the crane straight to work without proving it can lift safely at rated capacity. A crane that idles fine can still fail under real load if the structure, brakes or hydraulics are compromised. Putting it to work untested risks a dropped load and a serious incident on your first job.
How a professional handles it: A load test confirms the crane performs safely at its rated capacity before it earns money for you. Arranging this through a qualified provider gives you documented proof the crane is fit for service.
8.Forgetting your compliance obligations as the new owner
Buyers treat the sale as the end of the process, not the start of an ongoing duty. As the owner and operator you carry the WHS obligations to keep the crane inspected, maintained and safe. Overlooking this can void insurance and leave you exposed if the crane is ever involved in an incident.
How a professional handles it: Set up an inspection and maintenance schedule from day one so the crane stays compliant under your ownership. A compliance provider can map out exactly what your new crane needs and when.
9.Not budgeting for recommissioning and rectification
The purchase price is treated as the total cost, with no allowance for the work needed to make the crane safe and compliant. Rope replacement, an overdue inspection, worn components and rectification can quietly double the real cost of a cheap crane. A bargain stops being a bargain once you add the work it needs.
How a professional handles it: Get the crane's condition assessed before you buy so the full cost of ownership is known upfront. An inspection report lets you factor rectification into the price and negotiate accordingly.

Need a load test?
Discuss proof, static or dynamic testing for cranes, hoists, beams, lifting points and related equipment.
FREQUENTLY ASKED QUESTIONS
Should I get a used crane inspected before buying it?
Yes. An independent pre-purchase inspection is the single most valuable thing you can do before committing to a used crane. It reveals structural condition, outstanding compliance work and hidden faults so you know the real cost before you pay, and it gives you evidence to negotiate on. The cost of the inspection is small next to the cost of buying the wrong crane.
What documents should come with a used crane?
You should receive the crane's logbook, service and maintenance history, previous inspection and load test records, and the manufacturer's load charts and manuals. Missing or incomplete records are a warning sign and can make the crane harder to keep compliant. Always confirm these are available and complete before you agree to buy.
Does buying a used crane make me responsible for its compliance?
Yes. Once you own and operate the crane, the obligations to keep it inspected, maintained and safe under the WHS Regulations and AS 2550 fall to you. Any overdue inspection, unresolved fault or missing record becomes your responsibility. Setting up a compliance schedule from the day you take ownership protects you and your workers.
