View detailsHG series manual concrete placing boom of 12m, 15m and 18m, is a new product of our company produced for enlarging the range of concrete pouring and.

Concrete has to arrive at the formwork continuously and without segregation. That is the entire purpose of this product family: Manual Concrete Placing Boom equipment takes plastic concrete from a truck or mixer and delivers it horizontally along a pipeline or vertically through a placed boom, at a rate the finishing crew can absorb.
HAMAC supplies truck-mounted boom pumps for high-rise and large slabs, static and trailer line pumps for tunnels and long horizontal runs, spider placing booms for wide industrial floors, self-climbing booms that travel with the core of a tower, and separate placing masts for precast yards.
Buyers usually compare two things: whether the machine will hold its rated output on a hot day with damp aggregates, and whether anyone will answer the phone in year three. HAMAC designs for both.
Outrigger interlocks, boom angle limits and emergency stop circuits protect both crew and structure.
Hardened wear plates and cutting rings provide extended service intervals under abrasive mixes.
Steady flow keeps cold joints out of slabs and eliminates the double-handling cost of crane-and-skip methods.
Independent placing puts concrete precisely where the crew is working without occupying lifting capacity.
Choose engine power for remote sites or electric motors for tunnels and urban night work.
Integrated water tank, high-pressure pump and cleaning accessories reduce end-of-shift time.
Indicative ranges for standard configurations. Final values are confirmed against your project requirements.

Mass pours with sustained continuous output




Six defined stages, each with named deliverables, so nothing is left to interpretation.
We start with your mix design, hourly output target, aggregate size, jobsite power supply and site layout — not with a catalogue page.
Our engineering team issues a layout drawing, foundation loads, power requirement and an equipment list matched to the target output.
A fixed specification quotation with clear technical annexes protects both sides; no vague "standard configuration" wording.
Weekly production photos, welding and pressure test records, plus third-party inspection if your project requires it.
Container or break-bulk shipment, then on-site supervision of assembly, alignment, calibration and dry-run.
Remote diagnostics by video call, spare parts dispatch within 48 hours for stocked items, and periodic return visits.
