On 27th, December 2016, one set of concrete placing boom was put into the container and then delivered to Ecuador. This customer visited us approximate 6 weeks ago, he visited many suppliers include some world-famous brand when he was in China. Finally, he thought our quality and our reasonable price was what he want. So, when he came back to Ecuador, he remitted the advance payemnt to us. Hope this concrete placing boom will promote Ecuador market.
Most enquiries we receive start after a fleet problem — a pump that loses pressure on long booms, a mixer whose drum liners wear prematurely, a batching plant whose weighing tolerance drifts. Each of those has an engineering answer, and that answer belongs in the design stage rather than in the warranty claim.
Related Equipment Capability
Loads its own materials
Hydraulic loading bucket with weigh-by-drum keeps proportions consistent batch to batch.
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.
| 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 |
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 HGY28 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.
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.
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.
Is spare parts supply reliable?
Wear items such as drum liners, hydraulic seals and chute liners are stocked and ship with the machine as a starter kit.
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.
