Concrete Pumps & Placing Booms
Placing Boom Spider Type
Concrete has to arrive at the formwork continuously and without segregation. That is the entire purpose of this product family: Placing Boom Spider Type 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.
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.
Key Advantages of Placing Boom Spider Type
S-tube valve reliability
Hardened wear plates and cutting rings provide extended service intervals under abrasive mixes.
Safety built into the controls
Outrigger interlocks, boom angle limits and emergency stop circuits protect both crew and structure.
Diesel and electric variants
Choose engine power for remote sites or electric motors for tunnels and urban night work.
Continuous placement
Steady flow keeps cold joints out of slabs and eliminates the double-handling cost of crane-and-skip methods.
Wash-out systems included
Integrated water tank, high-pressure pump and cleaning accessories reduce end-of-shift time.
Boom reach without a crane
Independent placing puts concrete precisely where the crew is working without occupying lifting capacity.

Typical Applications
The applications below reflect the situations in which HAMAC customers most commonly deploy it.
High-rise buildings
Vertical concrete delivery exceeding 100 m using riser pipelines or self-climbing booms
Bridges and viaducts
Long horizontal pumping runs to piers and deck segments
Dams and hydropower
Mass pours with sustained continuous output
Large industrial slabs
Spider booms covering wide floor areas without repositioning
Precast and yard casting
Fixed placing booms serving repetitive casting beds
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 Placing Boom Spider Type
Do I need a special mix design for pumping?
Yes, a pumpable mix: continuous grading, sufficient fines (roughly 350-400 kg/m³ below 0.25 mm), and no gap-graded coarse aggregate.
Boom pump or line pump?
If the pour point moves often and sits within boom reach, a boom pump wins on labour. If concrete must travel far horizontally or vertically beyond the boom, use a line pump and pipeline.
What is the expected service life of wear parts?
Delivery cylinders 40,000-80,000 m³, cutting ring and wear plate 15,000-30,000 m³ depending on aggregate abrasiveness.
Can the machine handle low-slump concrete?
Most units are optimised for 120-200 mm slump; below that, pressure requirements rise sharply and output falls.
How do I prevent pipeline blockages?
Keep slump at 120-180 mm, maintain adequate fines, prime the line with mortar before each pour and avoid long idle periods.
