TP25M4 Truck-Mounted Concrete Boom Pump — 24.2 m

The TP25M4 is the compact boom pump in the TRUEMAX truck-mounted range — the small, agile machine for sites the bigger trucks cannot reach. Its 4-section M-fold boom reaches 24.2 m vertically and 20.6 m horizontally and slews a full 360°, so it can place concrete anywhere around the truck without repositioning. On a light Steyr 4×2 chassis at just 18,500 kg, this 24 m concrete pump is the easiest in the range to drive into tight urban streets, residential plots and confined yards, and the quickest to set up and move on. It pumps up to 100 m³/h and runs a PLC/CAN-BUS electronic control system with wireless remote operation.

The full 360° rotation is the headline: most boom pumps slew ±270°, but the TP25M4 turns a complete circle, which removes blind spots and re-positioning on tight, irregular plots. Like every TRUEMAX boom pump it is built and tested in our own factory in Haining — the boom is fabricated from imported high-strength low-alloy steel with a yield strength above 900 MPa, and every boom passes 100% non-destructive testing before it leaves the line. The company holds ISO 9001:2015, CE and SGS certification and serves more than 120 countries.

1.Full 360° slewing — The boom turns a complete circle, so the truck can place concrete all around its position without moving — a real advantage on tight, irregular sites.

2.Compact, light 4×2 chassis — At 18,500 kg on a Steyr 4×2, it drives into narrow access, sets up fast and travels at up to 100 km/h between jobs.

3.Reliable power transmission — Well-known-brand transmission components secure the reliability of the power system.

4.Imported multi-way valve — Ensures safe, stable operation under load.

5.4-section M-fold boom — The M-type folding boom opens and closes smoothly and stows compactly for transport.

6.Large water tank + high-pressure cleaner — Fast, thorough cleaning after the pour.

7.Automatic centralised lubrication — Greases the main wear points automatically to extend equipment life.

8.PLC/CAN-BUS electronic control — Coordinates with the chassis diesel engine, with wireless and cable remote control.

Dimensions & Working Range

The working-range diagram shows the boom’s reach envelope: the heights and horizontal distances the TP25M4 can place concrete at from a single set-up, around a full 360°. Vertical reach is the maximum height to the end hose; horizontal reach is measured from the slewing centre. Actual reach on site depends on outrigger spread and ground conditions — read it together with the dimensional drawing to confirm the truck fits your access and set-up area.

Applications

The TP25M4 is built for the small, tight and low-rise work where a large boom pump cannot fit or is not worth the cost — and where the full 360° slewing earns its keep on awkward plots.

Urban and confined-site pours

Narrow streets, inner-city plots, basements and yards where access is tight: the compact 4×2 truck gets in, and the 360° boom reaches around the whole site from one position. A practical small concrete pump truck for dense urban work.

Houses, villas and low-rise buildings

With 24.2 m of vertical reach, this 24 m boom pump places concrete directly on roughly 7–8 storeys — covering houses, villas, low-rise blocks and the upper floors of small commercial buildings.

Slabs, foundations, driveways and repairs

Ground slabs, footings, driveways, swimming pools and renovation or repair pours suit a compact boom pump that can be positioned precisely and cleaned up quickly, with up to 100 m³/h through the 260 × 1800 mm cylinder and DN125 line.

Standard mixes

At 5.6 MPa pumping pressure with an S-valve and a 700 L hopper, the TP25M4 handles standard concrete mixes for low-rise and general construction. For high-rise and high-pressure mixes, the larger RZ models are the right tool.

FAQs

How many floors can the TP25M4 reach?

Its 24.2 m vertical reach places concrete directly on roughly 7–8 storeys from a single set-up, depending on floor-to-floor height and where the truck can stand. It is designed for low-rise buildings, houses and ground-level work rather than high-rise towers.

What makes the TP25M4 different from the larger TP models?

Size, weight and rotation. It is the compact model: a 4-section M-fold boom reaching 24.2 m with full 360° slewing, on a light Steyr 4×2 chassis at 18,500 kg — about half the weight of the mid-range TP38RZ5. The bigger RZ5 and RZ6 models reach 38–62.5 m on heavier 6×4 and 8×4 chassis with higher output and pressure for mid- and high-rise work. Choose the TP25M4 when access, weight and manoeuvrability matter more than reach.

Why does the 360° slewing matter?

Most boom pumps slew ±270°, leaving a blind sector behind the truck. The TP25M4 rotates a full 360°, so on tight or irregular plots it can place concrete all around its position without being repositioned — saving setup time and making it easier to work in confined spaces.

What chassis does it come on?

The TP25M4 is supplied on a Steyr 4×2 chassis with a 210 kW engine and a top speed of up to 100 km/h. The light 4×2 platform is what makes it compact, fast on the road and easy to set up in tight access — the trade-off is that it is sized for low-rise rather than high-rise work.

Can it pump high-strength or fibre-reinforced concrete?

It is built for standard mixes on low-rise and general construction, at 5.6 MPa pumping pressure with an S-valve and a 260 × 1800 mm cylinder. For demanding high-strength or fibre-reinforced mixes on taller structures, the higher-pressure RZ models are the better choice.

What is included, and how is it delivered?

The standard unit includes the boom pump on the Steyr 4×2 chassis, remote controls and the wash-down system. Delivery, packing and shipping terms (FOB / CIF), spare-parts kits, installation, commissioning and operator training are quoted to your project.

Where the TP25M4 fits in the TRUEMAX boom-pump range

The TP25M4 is the compact entry point to the TRUEMAX TP range, which runs from this 24.2 m model up to the 62.5 m TP63RZ6. It stands apart from the rest: a 4-section M-fold boom with full 360° rotation on a light 4×2 chassis, where the mid-range TP38RZ5 and TP43RZ5 step up to a 5-section RZ boom on a 6×4 chassis (38–43 m), and the high-rise RZ6 models reach 49–62.5 m on an 8×4 chassis. As a 24 m boom pump it is the tool for the smallest, tightest jobs; for buildings above about 8 storeys, the longer-reach models take over. The choice across the range comes down to the reach your work needs and the access your sites allow.

How a boom pump works with the rest of the concrete chain

A truck-mounted boom pump is one link in the concrete delivery chain. Concrete is produced at a batching plant, hauled to site by a concrete truck mixer, and placed by the pump. A boom pump such as the TP25M4 both pumps and places in a single machine — it drives itself to site, sets up, and the boom delivers concrete straight to the pour, which is faster and more accurate than a line pump pushing concrete through ground-laid pipe. For larger or taller work beyond a compact boom pump, contractors move up to a longer boom pump, or pair a stationary concrete pump with a concrete placing boom to reach high-rise floors.

Compact boom pump vs line pump for small jobs

On the smallest jobs, the choice is often between a compact boom pump like the TP25M4 and a line pump. A boom pump (called a concrete pumper in North America, and a concrete lorry pump in the UK) places fast and precisely over obstacles and is quick to set up; a line pump — including the truck-mounted line pump — is cheaper and better where access is too tight even for a small boom truck, or where concrete only needs to travel horizontally at ground level. Many contractors keep both for different site conditions.
