JLG 340AJ Boom Lift Price Guide
A broad indicative used-price band for the JLG 340AJ, modelled from a sourced new price and HeavyBook’s disclosed boom lift depreciation curve. It is not verified sold data; age, hours and condition decide where a real machine lands.
We don't have a verified used price range for the JLG 340AJ right now.
The transparent estimate below is a modelled reference from a sourced new price. It is deliberately separate from verified market ranges and never counts as market evidence.

Used — indicative estimate
This is a broad modelled estimate, not a verified market range. It starts with the sourced indicative new price of $99,600 and applies HeavyBook’s declared depreciation curve for boom lifts at the reference ages shown above. A real machine can sit outside it because of hours, condition, attachments and location. See the method →
The 340AJ is JLG's compact diesel knuckle boom, a hire-yard staple that filters into private hands as rental fleets rotate stock. It suits builders, painters and facility-maintenance crews who need up-and-over reach around obstructions with narrow site access. Australian used examples are overwhelmingly ex-rental, almost always the Kubota diesel with four-wheel drive and the articulating jib fitted as standard; dual-fuel versions surface only occasionally. Supply skews to the eastern seaboard, dominated by mid-life machines from the model's core production run. The price spread is wide, driven less by age than by hours, boom wear and service history — and critically by where a machine sits against its ten-year major inspection, which can consume a meaningful share of its value. Budget for that, verify the logbook, and check slew and jib pins for slop before committing.
What a JLG 340AJ is used for
The JLG 340AJ is a compact articulating boom lift — its jointed boom reaches up and over obstacles to position where a straight boom or scissor lift cannot.
- External building maintenance and cleaning
- Reaching over plant, landscaping or fixed obstacles
- Steel erection, signage and facade work
- Tree work and arboriculture
- Tight-access construction on rough ground (four-wheel drive)

What Moves the Price
In-date major inspection
The ten-year major inspection dominates boom-lift value in Australia. Recently inspected units command a premium; due units trade at a discount that mirrors the job.
Four-wheel drive & jib
Rough-terrain drive and an articulating jib are what site buyers pay for. Slab-only electric booms serve a narrower market.
Ex-rental fleet churn
Rental fleets turn booms over in bulk, and those sell-offs set the floor. Owner-operator machines with history recover the gap.
Boom wear & slew
Sloppy boom pivots, worn slew rings and weeping cylinders are expensive fixes — buyers quote them straight off the asking price.
