Concrete Mixer Truck Specifications
The figures below describe typical industry specifications for this class of equipment rather than a single fixed model. Use them to scope a requirement, then confirm exact figures against the supplied unit before purchase.
| Specification | Typical value |
|---|---|
| Drum volume | 6–10 m³ geometric; 5–8 m³ typical yield |
| Chassis | 6×4 rigid, 250–340 hp class |
| Drum drive | PTO hydraulic or separate donkey engine |
| Mixing / agitating speed | 12–18 rpm mixing; 1–3 rpm agitating in transit |
| Discharge | Rear chute, optional conveyor or pump feed |
| Water tank | 400–800 L for washout, not for watering the mix |
| Fuel consumption | 18–30 L/h including drum drive |
| Payload implication | Legal axle weights often cap yield below drum size |
What a Concrete Mixer Truck Is Used For
- Plant foundations, mill plinths and tank rings
- Building slabs, columns and beams
- Mine road culverts and drainage
- Shotcrete supply to underground (with pump)
- Remote site pours from a central batch plant
Maintenance Schedule
Most premature failures in this equipment class trace back to a missed routine check rather than a design fault. The intervals below are a practical starting schedule; adjust them to your duty cycle and the manufacturer manual.
| Interval | Task |
|---|---|
| Every pour | Wash the drum and chutes immediately after discharge; set concrete in the blades is a rebuild, not a clean. |
| Daily | Inspect drum rollers, hydraulic hoses and chute hinges; check water-tank function. |
| Weekly | Inspect interior blades for wear and build-up; torque roller brackets. |
| 500 h | Drum-drive hydraulic filters; gearbox oil. |
| Annually | Blade replacement as a set; roller and race inspection. |
Frequently Asked Questions
How long can mixed concrete stay in the drum?
Typically 90 minutes from first water to final place, less in Tanzanian heat. Beyond that the mix loses workability and then strength. Plan the batch plant, the road and the pour so the truck is emptying, not waiting. A truck queued for an hour in Geita sun is a rejected load.
Why must I not add water on site?
Because strength is a function of water-cement ratio. Extra water makes the mix easy to place and quietly misses the specified MPa. If the mix is stiff, use a superplasticiser batched at the plant, not a hose at the chute. Mill plinths and tank rings are unforgiving of this shortcut.
Drum size versus what I can legally carry?
An 8 m³ drum on a 6×4 chassis often cannot legally carry 8 m³ of concrete without exceeding axle limits. Yield is set by weighbridge law as much as by drum volume. Confirm payload with the supplier rather than assuming the brochure number arrives on site.
