Line Pump vs Boom Pump: Which Concrete Pump Do You Actually Need in 2026
Share
If you're hiring a concrete pump in 2026 — whether you're a builder, owner-builder, formworker, or just trying to figure out what to book for a 6m³ pour — the first question is always the same: line pump or boom pump?
Get it wrong and you blow your budget, your schedule, or both. Get it right and the pour goes off without a hiccup.
This is the no-fluff Pumplife guide to choosing between line pumps and boom pumps for any job, written by people who actually live on the line.
What's the actual difference between a line pump and a boom pump?
A line pump (sometimes called a trailer pump or stationary pump) sits on a trailer or skid. Concrete travels from the hopper through rigid steel and flexible rubber lines that you run by hand to wherever the pour is happening. They're typically rated for 30–60 cubic metres an hour and can push concrete horizontally up to ~150m or vertically up to ~30m on a good day.
A boom pump (also called a truck-mounted concrete pump or placer boom) is a full truck with a folding hydraulic boom on top. The operator drops the outriggers, unfolds the boom, and places concrete with millimetre precision wherever the boom reaches — typically 21m up to 65m+ for the big units. Outputs of 80–180 m³/hr are standard.
The quick answer:
Line pump = small to medium pours, tight access, residential, slabs, footings.
Boom pump = big volumes, anything with reach problems, commercial, high-rise, complicated formwork.
When a line pump is the right call
Line pumps win on small jobs and tight sites. If your pour is under ~25 cubic metres, your truck access is rough, or you're pumping into a backyard, basement, or a job you can't get a 30-tonne truck near, a line pump is almost always cheaper and faster to set up.
Typical line pump jobs:
Residential slabs and house footings under 20m³
Shotcrete and pool jobs
Underpinning and remedial concrete
Basement pours where reach matters more than volume
Driveways, paths, retaining walls
Grout, screed, and lightweight mixes
Line pumps are also the only realistic option when you physically cannot park a boom truck near the pour — narrow inner-city streets, sloping blocks, jobs behind houses, or anywhere overhead powerlines kill the boom option.
The trade-off: every metre of line you run adds friction. Long runs slow output, drop your effective m³/hr, and increase blowout risk. A good line pump operator manages line length, line direction, and mix design to keep flow consistent.
When a boom pump is the right call
The minute volume goes up or access gets weird up high, boom pump pays for itself. A 28m or 36m boom pump on a 60m³ slab will out-pour two line pumps and three labourers, and the placement is so much more precise that your finishers will thank you.
Typical boom pump jobs:
Commercial slabs 30m³ and up
Multi-storey suspended slabs
Bridge work, civil structures, infrastructure
Any job where you need to place over a building or obstacle
Blockfill where speed kills
High walls, tall columns, lift cores
The boom moves concrete fast and clean — the operator can reach into formwork that no line pump crew can get to without breaking their backs. On commercial work the labour savings alone make the bigger pump rate cheap.
The trade-off: setup space, outrigger footprint, overhead clearances, and a higher hourly rate. You need a clear path in, clear airspace above (no powerlines, no awnings), and stable ground for the outrigger pads.
Volume thresholds — rough rules from the field
Under 15 m³: line pump every time unless reach is impossible.
15–30 m³: line pump usually wins on price; boom only if access is bad.
30–60 m³: boom pump usually wins on speed; line pump only if you genuinely can't fit a boom truck.
60 m³ and up: boom pump, almost without exception. The labour and time difference is brutal.
These aren't laws, they're field heuristics. Every job is different. A 20m³ pour over a two-storey house with no rear access is a boom job no matter the volume. A 50m³ remote rural slab with great access might still go line if the pumper has a 4-inch trailer setup.
What does it cost to hire each in Australia?
Line pumps: typically $600–$1,200 minimum call-out for the first 2–3 hours, then around $200–$300 per hour after. Some operators charge per cubic metre, some per hour, some hybrid.
Boom pumps: starts higher — $1,200 to $2,500+ for a half-day on a 28m–32m boom, rising fast for 42m+ and big-fleet operators. Hourly rates usually $350–$500 once the minimum is burned.
The number that actually matters is dollars per m³ pumped — divide the all-in price by the volume. Boom pumps almost always win this metric on bigger pours because they place faster and need less crew.
Questions to ask before you book
What's the volume in m³? (Round up — concrete suppliers will too.)
What's the mix and slump?
How far from where the truck can park to the pour location?
Are there overhead powerlines? Awnings? Roofs?
How's the ground for outriggers — bog, slab, or solid?
What time does the agi truck arrive and how many m³ per truck?
Does the operator bring their own crew or do you supply labour?
Good pumpers will ask you most of these before you ask them. If the operator on the phone doesn't, that's your sign.
The Pumplife verdict
Boom for volume and reach. Line for tight, small, or weird. There's no universal winner — there's only the right pump for the pour in front of you.
When in doubt, ring a local operator and describe the job. Any pumper worth their salt will tell you straight which unit to book — even if it's not the one parked in their yard. That's the difference between a pumper and a pumpy.
