Brief the supplier properly
Work out working height and outreach
Working height is roughly platform height plus 2 metres. If you must reach over a roof edge, awning or plant, you need a boom with enough outreach—not just height.
Check the floor and ground
Suspended slabs, mezzanines and pavers have load limits. Ask for the machine's wheel or point load and compare it with engineering advice.
Measure doorways and ramps
Stowed width, height and weight decide whether a machine can get in. Lifts, ramps and door openings are common blockers indoors.
Plan rescue and exclusion zones
Have a rescue plan for a stranded or injured operator and set up exclusion zones below the platform, particularly near pedestrians.
For Katherine specifically, tell the supplier the exact site address so they can confirm the depot the machine will come from, the travel or float charge and any NT permit needs.
