An older machine does not need to stop working completely before it starts costing your business money.
A scissor lift with recurring electrical faults, a forklift that spends more time in the workshop, a telehandler with slow hydraulics or a generator that cannot be trusted under load can all remain technically operational. The problem is that they are no longer dependable.
That is where the hidden cost of old equipment begins.
The workshop invoice is only one part of it. There is also freight, emergency hire, lost labour, delayed work, parts lead times and the time spent managing the same fault again. For contractors and fleet managers, the biggest cost is often the disruption created when a machine fails at the wrong time.
Older equipment can still deliver strong value when it is well maintained, supported by available parts and suited to the work. The decision to replace it should never be based on age alone.
The real issue is whether the machine is still making money for the business, or whether the business is now spending too much time and money keeping it alive.
What Does Old Equipment Really Cost to Keep Running?
Most repair decisions begin with a workshop quote.
A charger fails on a scissor lift. A forklift develops a transmission or hydraulic issue. A telehandler needs another set of hoses. A lighting tower has an alternator fault. A generator requires a control board that is no longer held locally.
The quote arrives and the comparison looks simple: repair the existing machine or spend considerably more on a replacement.
That comparison is incomplete.
The true cost starts with the repair, but it also includes the consequences of the machine being unavailable.
If the forklift is down, stock may not be unloaded or moved through the warehouse. When the telehandler is off site, crews may need to wait or change the sequence of work. If the generator fails, temporary power may need to be brought in urgently. If an EWP is unreliable, the operator may lose confidence in the machine before it officially breaks down.
There are also costs that rarely appear against the asset itself:
- Transport to and from the repairer
- Technician call-out fees
- Replacement equipment hire
- Idle labour
- Overtime to recover lost productivity
- Delayed deliveries or project milestones
- Management time spent arranging repairs and alternatives
- Lost work when suitable equipment is not available
One repair does not make a machine uneconomical. Every fleet has occasional failures, including newer equipment.
The warning sign is repetition.
When the same machine creates several repair invoices, repeated call-outs or regular downtime across a 12 to 24-month period, the business needs to stop assessing each fault in isolation.
Add the full cost together. Include repairs, servicing, freight, hire and downtime. Then compare that figure with the cost of replacing the machine with equipment that is reliable, supported and better suited to the work ahead.
That is when the repair-versus-replace decision becomes a commercial calculation rather than a reaction to the latest breakdown.
Repeated repairs, freight and downtime can push the real cost well beyond the workshop invoice.
When Old Equipment Starts Costing Productivity
A machine can pass its pre-start and still be holding the business back.
An electric scissor lift that no longer gets through a full shift creates charging delays and forces crews to plan around the battery. A forklift with a tired transmission or weak hydraulics takes longer to travel, lift and position every load. A telehandler with excessive play through the boom or slow hydraulic response makes precise placement harder and reduces operator confidence.
The same problem shows up with generators and lighting towers. A generator that starts cleanly with no load may still struggle when pumps, compressors or site facilities are connected. A short run in the yard does not confirm that it will accept and hold its rated load. Load-bank testing provides a controlled way to check performance under working conditions and can also expose issues such as wet stacking in lightly loaded diesel engines.
Lighting towers lose value when light output deteriorates, fuel consumption increases or recurring electrical faults make them unreliable after dark. The machine may still operate, but it no longer delivers the coverage or runtime the job requires.
These productivity losses rarely appear as a separate line in the accounts.
They show up through slower cycle times, additional charging, extra fuel, operator workarounds and jobs taking longer than they should.
Capacity is another common issue. A business may still own a reliable 2.5-tonne forklift, but the work has moved into heavier loads or larger attachments. A telehandler purchased for smaller commercial projects may lack the lift height, forward reach or capacity needed for the contracts now being targeted.
At that point, the equipment is not old because of the number on the compliance plate. It is old because the business has moved past it.
A proper repair-or-replace review should compare the machine against the next three to five years of work. Rated capacity, duty cycle, lift height, power source, site conditions and expected annual hours all matter. Keeping a fully paid-off machine makes little commercial sense when it slows the work or prevents the business from quoting larger jobs.
That lost capability is part of the hidden cost of old equipment, even when the workshop spend remains manageable.
Older equipment can remain operational while slower performance, wear and reduced reliability continue to affect productivity.
EWP 10-Year Major Inspection Cost: Repair or Replace a Scissor Lift or Boom Lift?
The 10-year mark creates a clear decision point for owners of scissor lifts and boom lifts.
Safe Work Australia guidance calls for an EWP major inspection after 10 years of service and every five years after that. AS/NZS 1418.10 covers the design and construction of elevating work platforms, while AS 2550.10:2025 addresses safe use, inspection and maintenance. The current standard places strong emphasis on following the manufacturer’s maintenance requirements.
A major inspection is far more involved than a routine service or periodic inspection. Critical components are dismantled and examined to assess fatigue, corrosion, cracking, wear and structural integrity. Safety systems and functions are tested, and any faults identified during the process need to be rectified before the machine returns to service.
A major inspection includes detailed checks of safety-critical components such as pins, welds, hydraulics and structural sections.
The cost can materially change the economics of an older EWP.
Published Australian industry estimates place the inspection itself at roughly 15 to 35 per cent of the machine’s original purchase price, depending on the model, condition and scope. That figure generally excludes repairs uncovered during the inspection.
Take a slab scissor lift originally purchased for $20,000. Using that broad industry range, the major inspection could account for $3,000 to $7,000 before allowing for batteries, tyres, pins, bushes, hydraulic repairs, corrosion treatment or damaged electrical components.
The numbers become much larger on an articulated or telescopic boom lift. The machine has more structural sections, pivot points, hydraulic components and safety-critical systems to inspect. One substantial rectification item can push the final cost well beyond the initial inspection quote.
Downtime also needs to be budgeted. A clean slab scissor with strong service history is one proposition. A boom lift with corrosion, worn pins and difficult-to-source components is another.
The hands-on inspection may account for several workshop days, but booking time, dismantling, non-destructive testing, parts supply and rectification can extend the total time off fleet considerably. If major components are required, the machine can be unavailable for weeks rather than days.
The 10-year inspection is not automatically a reason to sell an EWP. A quality machine with solid history and years of productive work ahead can justify the investment.
The mistake is waiting until the inspection is due before running the numbers.
Owners should review the machine six to twelve months before the 10-year date. Compare the estimated inspection and rectification cost with its current market value, replacement cost, annual utilisation and likely earnings over the next five years.
That provides enough time to book the inspection properly, plan a replacement or sell the machine while it still has useful value.
Parts Availability and Plant Compliance Can Decide the Issue
Some older machines remain mechanically sound but become difficult to support.
The problem is often an electronic component rather than the engine, chassis or boom structure. A discontinued control board, proprietary joystick, display module, ECU, battery charger or wiring harness can leave an otherwise serviceable machine parked up.
Parts may still exist overseas, but that introduces freight costs and lead times. In other cases, the only option is a used or remanufactured component with limited warranty and no certainty around future availability.
A generator can face the same issue with an obsolete controller or automatic voltage regulator. An older lighting tower may need a ballast, alternator component or electrical assembly that is no longer stocked locally. Forklifts and telehandlers can become difficult to support when transmission controllers, dash assemblies or model-specific hydraulic components reach the end of manufacturer support.
Once a critical part becomes obsolete, the next breakdown is no longer a normal repair decision. It becomes a search for whatever can be found, at whatever price and lead time the market allows.
Plant history matters just as much as parts availability.
Australian WHS guidance requires maintenance, inspection and any necessary testing to be completed by a competent person in line with the manufacturer’s recommendations. The person managing or controlling the plant also carries responsibility for providing and maintaining safe equipment.
Large contractors and infrastructure sites regularly ask for evidence before plant is cleared for use. Depending on the machine and project, that can include:
- Current inspection reports
- Service and repair history
- Operator manuals and logbooks
- Plant risk assessments
- Compliance statements and test certificates
- Evidence of safety-device testing
- Generator load-bank results where operational reliability is critical
Safe Work Australia identifies inspection results, test certificates, manufacturer specifications, maintenance history and major repair records among the information that should be retained for plant.
A machine with incomplete records can be difficult to approve for site, trade or sell. Missing documentation also makes it harder to prove that recurring faults were investigated and repaired correctly.
When inspection dates are overdue, safety systems are unreliable or maintenance history cannot be produced, the risk extends beyond another repair invoice. The machine can be stood down, rejected at pre-start or removed from the project altogether.
That is when the hidden cost of old equipment becomes a safety and commercial exposure, not simply a maintenance issue.
Repair or Replace Equipment Before Downtime Makes the Decision
The best time to review an older machine is while it is still working.
Once it fails on a live project, the decision changes. The priority becomes finding whatever is available, arranging urgent transport and getting the crew moving again. There is less time to compare brands, capacities, finance structures or the machine’s likely value over the next five years.
A proper repair-or-replace review should begin with the previous 12 to 24 months.
Add up the repairs, servicing, call-outs, freight and replacement hire. Include the cost of lost operating time and the management effort required to keep the machine available. Then look ahead at upcoming inspections, major component replacements and parts availability.
For EWPs, that includes the 10-year major inspection and the five-year inspection cycle that follows. With generators, it may include load-bank testing, control-system support and engine condition. Forklifts and telehandlers, the review should include transmission performance, hydraulic wear, safety systems, attachment suitability and the quality of the plant history.
The replacement cost also needs to be assessed properly.
A new machine may offer warranty coverage, better parts support, improved efficiency and more predictable servicing. Finance can spread the purchase across the period in which the equipment earns revenue, rather than requiring the full cost upfront.
Modern, well-supported equipment can improve reliability, reduce downtime and strengthen long-term fleet performance.
Depending on the business and the asset, options may include a chattel mortgage, hire purchase or finance lease, with a balloon or residual structure used to reduce monthly repayments. The right structure depends on cash flow, asset use and tax position, so finance and accounting advice should form part of the decision.
The key is to compare the total cost of keeping the old machine with the total cost of moving into something newer.
Age alone does not decide whether equipment should be replaced. Condition, reliability, utilisation, compliance, parts support and the work ahead matter far more.
