Self-Loading Concrete Mixers
Self
For contractors working across several small sites per week — rural roads, canal linings, housing clusters, small municipal works — this removes the need to move a full batching plant or to keep a fleet of trucks supplied over long haul roads.
A Self replaces the loader, the batching plant and the mixer truck on small and dispersed jobsites. The hydraulic arm loads aggregate and cement from the stockpile into its own drum, water is metered by an on-board system with an electronic weighing display, and the machine then travels to the pour point and discharges through a rotating chute.
Choosing a Self is rarely decided by the price tag alone. Downtime, concrete quality consistency, fuel consumption per cubic metre and the availability of wear parts across a five-year operating window matter far more to the final cost per tonne or per cubic metre produced.
Key Advantages of Self
Loads its own materials
Hydraulic loading bucket with weigh-by-drum keeps proportions consistent batch to batch.
Low cost per cubic metre
Best economics appear where daily volume sits between roughly 30 and 200 m³.
All-terrain chassis
Articulated frame, four-wheel drive and high-flotation tyres cope with muddy access roads.
Genuinely independent
No loader, no batching plant, no mixer truck — one machine completes the whole concrete chain.
Rotating and elevating drum
Discharge to either side and over the machine, useful on narrow alignments and inside structures.
Electronic batching
Digital water meter and batch counter provide traceable output records.
Technical Parameters
Indicative ranges for standard configurations. Final values are confirmed against your project requirements.
| Parameter | Specification |
|---|---|
| Batch output | 1.2 - 6.5 m³ per batch |
| Drum capacity | 1.8 - 9 m³ |
| Drum rotation | Up to 270° hydraulic rotation |
| Chassis | Articulated 4-wheel drive, 4-wheel steer option |
| Engine power | 55 - 130 kW |
| Water system | Electric pump with digital flow meter and pressure washer |
| Loading bucket capacity | 0.3 - 0.8 m³ |
| Weighing system | Electronic drum weighing with batch counter and printer option |
Typical Applications
On typical projects this equipment is selected where output reliability governs the whole schedule.
Irrigation canals and culverts
Continuous linear pours outside the plant supply radius
Mining camps and access roads
Self-sufficient production in remote areas
Emergency and relief works
Rapid deployment after floods or landslides
Rural and secondary roads
Small pours along long alignments where a batching plant cannot follow
Small urban jobsites
Footings, slabs and retaining walls in tight access conditions
From Enquiry to Commissioning
Six defined stages, each with named deliverables, so nothing is left to interpretation.
Requirement study
We start with your mix design, hourly output target, aggregate size, jobsite power supply and site layout — not with a catalogue page.
Scheme design
Our engineering team issues a layout drawing, foundation loads, power requirement and an equipment list matched to the target output.
Quotation & contract
A fixed specification quotation with clear technical annexes protects both sides; no vague "standard configuration" wording.
Production & inspection
Weekly production photos, welding and pressure test records, plus third-party inspection if your project requires it.
Delivery & installation
Container or break-bulk shipment, then on-site supervision of assembly, alignment, calibration and dry-run.
After-sales
Remote diagnostics by video call, spare parts dispatch within 48 hours for stocked items, and periodic return visits.
Frequently Asked Questions about Self
Does it need a skilled operator?
It needs a trained operator, and most crews learn the full cycle within a week; we provide training during commissioning.
Can it discharge into a pump?
Yes — the rotating chute feeds a pump hopper directly, extending reach to upper floors.
What maintenance is critical?
Daily greasing of the drum rollers and loading arm, weekly checks of hydraulic pressure and tyre condition, and regular drum cleaning to prevent build-up.
How accurate is the batching without a full plant?
Electronic drum weighing holds cement and water within about ±2%, which is sufficient for C20-C35 structural concrete when verified by test cubes.
How much concrete can one machine produce per day?
Typically 80-200 m³ depending on haul distance, batch size and how many load cycles are feasible per hour.
