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 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.
