Genie Z-45/25J RT Boom Lift Price Guide
A broad indicative used-price band for the Genie Z-45/25J RT, 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.

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 $119,990 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 Z-45/25J RT is one of the most common diesel knuckle booms in Australian hire fleets, and the used market is correspondingly dominated by ex-rental units. It competes head-to-head with the JLG 450AJ in the same four-wheel-drive rough-terrain class, valued for zero tailswing and a jib that works up and over obstructions. Its boom is well past the eleven-metre line, so operators need a WP high-risk work licence. The single biggest driver of a used unit's price is the ten-year major inspection required of boom lifts in Australia — the inspection is costly relative to values in this class, so a machine with a documented completed inspection trades in a different bracket from one with it looming. Genie has since superseded the model, but parts support continues.

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.
