Do Concrete Trucks Have Pumps Built In?
By PumpX Team ·
Short answer: no. A typical concrete truck, the one with the big rotating drum, is a mixer or agitator, not a pump. It delivers concrete down a chute. If you see a truck with a long folding arm and a hopper at the back, that is a different machine: a concrete pump truck.
What a standard concrete truck does
A ready-mix truck carries concrete in a rotating drum. The drum turns slowly in transit to keep the mix from setting or segregating. At the site, the driver reverses the drum rotation to discharge the concrete, which runs down a chute under gravity.
The driver can usually extend the chute a little with extension sections, but reach is limited. The concrete has to be near where the truck can park.
What a concrete pump does
A concrete pump is a separate machine that takes concrete from the mixer truck, via a hopper, and pushes it through a pipeline or boom to the placement point. The mixer truck backs up to the pump, discharges into the hopper, and the pump moves the concrete where the chute cannot reach.
The machines you might see
| Machine | What it is | Pumps concrete? |
|---|---|---|
| Ready-mix truck (transit mixer) | Drum and chute | No |
| Boom pump truck | Pump with folding boom on a truck chassis | Yes |
| Line pump (trailer or truck) | Pump with pipe and hose | Yes |
| Concrete conveyor/placing truck | Conveyor belt boom (some mixers have this) | No, conveys |
| Volumetric mixer | Mixes on site from separate materials, often with a chute | Usually no |
Some mixer trucks carry a conveyor arm that moves concrete a short distance. That is a conveyor, not a pump. Combination machines that both mix and pump do exist, but they are specialised and not what you see delivering most pours.
Why there is a separate pump
Pumps are expensive, heavy and need training to operate. The economics work like this: a mixer truck is simple and cheap per delivery, while a pump is brought in only when needed, for high-rise, long distances, tight access or fast placing. It is also why pumping is a specialist trade.
When a pump is brought in
- The pour is too far from the truck.
- The ground is soft or the site cannot take a heavy truck.
- The pour is above or below ground level.
- Speed matters on a large pour.
- Labour for barrowing is not practical.
If none of these apply, the concrete is often just chuted or barrowed.
Safety
If you are around a mixer truck or pump truck, keep clear of reversing vehicles and overhead lines. The pump end hose and the chute can both swing, and pipelines can be pressurised.
Why people get confused
It is easy to mistake one truck for another. A mixer truck with a long chute extension can look like it has an arm. A conveyor truck has a belt on an arm that looks a bit like a boom. And on a busy site, a mixer truck parked behind a pump truck can look like one vehicle from a distance. The simplest check is to look for the hopper and the rotating drum. If you see a drum, it is a mixer. If you see a hopper and an arm or pipes, it is a pump.
Key takeaways
- Standard concrete trucks are mixers with chutes, not pumps.
- A concrete pump is a separate machine, truck-mounted or trailer-mounted.
- Conveyors on some mixers move concrete a short distance but do not pump.
- A pump is hired when access, height, distance or speed demands it.
