HVAC & Rooftop Plant Lifting in Queensland
Old unit out, new unit in, about 20 minutes of flight time. Rooftop plant replacement without closing a lane of traffic or standing a 200-tonne crane in the loading dock for 6 to 8 hours.

The problem
Why this lift is hard the conventional way
Rooftop plant sits at the worst possible place for a crane: high, set back from the parapet, and above a street you cannot close.
- Boom reach over a parapet demands a very large, very expensive crane and 6 to 8 hours on site.
- CBD standing space requires lane closures, traffic management and police.
- Tenants and retail below cannot be disrupted during business hours.
- A failed chiller is an emergency; a crane booking is not.
How we do it
Aircraft, rigging, crew and duration
- Aircraft
- AS350, working maximum 800 kg on the hook
- Rigging method
- 40 m long line, remote release hook, four-leg sling set
- Crew
- Pilot, loadmaster, rooftop rigging pair, street-level controller
- Typical duration
- About 20 minutes of flight time per unit, plus rigging and isolation either side
- Structural check of the roof landing point and crane-free route to plinth.
- Old unit isolated, disconnected and pre-rigged by your mechanical contractor.
- Exclusion zone over the street or forecourt, held by marshals.
- Removal flight, then placement flight; unit landed onto anti-vibration mounts.

Site requirements
What you need ready on the day
- Structural sign-off for the roof landing and plinth positions.

Cost factors
What moves the number
Unit weight
Units above 800 kg are split into two lifts to suit the AS350's working maximum.
Number of units
Batching swaps into one mobilisation is the single biggest saving.
Building height and setback
Longer lines and tighter parapets add cycle time.
Window timing
Out-of-hours windows attract standby, not premium flight rates.
