The legs are the point
Most site cabins are lifted on and off a truck by crane or Hiab. A jackleg cabin carries its own lifting gear: four legs, corner-mounted, that screw or jack down to raise the cabin clear of the ground and up to the height of a truck deck. The truck reverses underneath, the cabin is set down on the deck, and the legs are wound back up under the floor for the trip. On the new site the legs go back down, the cabin is levelled, and it is in use the same day.
That is why jackleg cabins turn up so often on jobs that move — the crew that has to shift its own office at the end of a stage does not want to book a crane each time.
Where a jackleg cabin earns its keep
- Site offices — a desk, a plan table, a printer, somewhere the supervisor can close a door and take a call.
- Crib rooms — a table and chairs, a sink, a place out of the weather for smoko and lunch.
- Toilet and drying rooms — the same frame and legs, fitted out for amenities. Our listings include a 12 ft x 9 ft 2+1 jackleg toilet cabin.
- Yards and farms — a locked office or store that can be picked up and moved when the layout changes.
The sizes we list
The catalogue carries new jackleg cabins in 10 ft x 10 ft, 12 ft x 10 ft, 12 ft x 9 ft (the 2+1 toilet cabin), 16 ft x 10 ft as a site office, and 20 ft x 10 ft as an office cabin. Finishes include goosewing grey and Plastisol. Every listing shows its own photos and its GST-inclusive price, and those are the sizes and specs to work from — if a size you need is not listed, ask, because most of this range is built to order.
See the full range on the cabins for sale page, or the wider cabins and modified department.
Jackleg or skid-mounted — which one
If the cabin stays put for its whole life, a skid or crane-lifted cabin is fine and often cheaper. If it will move between stages, sites or paddocks, the legs earn their money the first time you avoid a crane hire and a half-day wait. The one thing a jackleg needs is a truck that can actually get underneath it — a clear, firm, level approach, not a boggy patch or a slope.
Site access and delivery
Cabins are delivered from our Melbourne yard on a flat-top, placed by crane or Hiab, and where the site suits a jackleg unit it can be set down without one. Delivery is free to any address in Australia, metro or remote — the freight is already in the listed price and nothing is added to the invoice. Collection from the yard is free as well. Transit after dispatch is 2–7 business days to Melbourne, Sydney, Brisbane, Adelaide and Canberra metro, 4–10 to regional VIC, NSW, QLD and SA, and 7–15 to Perth, Darwin and Hobart. Remote and unsealed-access sites run 10–21 business days, confirmed case by case. The delivery page sets it out in full.
Tell us the ground and the approach when you order — a photo of the drop point is worth more than a description, and it decides which truck we book. Nothing is charged on the website: checkout or a quote request returns an emailed invoice, paid by EFT, PayID or card link, and dispatch follows 2–5 business days after payment clears. Ring or message the team and we will talk you through the fit-out you need rather than sell you the wrong box.
