TP43RZ5 Truck-Mounted Concrete Boom Pump — 43 m

The TP43RZ5 is the mid-range model in the TRUEMAX truck-mounted boom pump range — the practical middle ground between the entry-level units and the big high-rise machines. Its 5-section RZ roll-fold boom reaches 43 m vertically and 39 m horizontally, placing concrete directly across roughly 13 storeys from a single set-up. That makes this 43 m concrete pump a fit for mid-rise buildings, highways, bridges and general construction, where 43 m of reach is enough and a more compact, economical truck is the sensible choice. The pumping system delivers up to 150 m³/h, and the truck-mounted concrete pump runs a PLC/CAN-BUS electronic control system with wireless remote operation.

The TP43RZ5 sits on a single, road-friendly Sitrak 6×4 chassis, which keeps weight and cost down compared with the 8×4 high-rise models while still giving a stable outrigger base. 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. Reliable power transmission — Well-known-brand transmission components secure the reliability of the power system.

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

3. Smart outrigger layout — Telescopic rear outriggers swing out and front outriggers use an “X” type, so the truck can set up in narrow site conditions.

4. Optimised boom design — The 5-section RZ boom folds and unfolds smoothly, with a wide working envelope to suit different placements.

5. High-reliability pneumatics — Durable pneumatic components throughout.

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 TP43RZ5 can place concrete at from a single set-up. 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 TP43RZ5 is built for the everyday mid-rise and infrastructure work that makes up most of the market — projects that need solid reach and output without the size, weight or cost of a high-rise machine.

Mid-rise residential and commercial buildings

With 43 m of vertical reach, this 43 m boom pump places concrete directly on roughly 13 storeys without a separate riser line — covering the low- and mid-rise buildings that dominate most construction programmes.

Roads, highways and bridges

The 39 m horizontal reach and ±270° slewing suit road and bridge work, deck pours and foundations where the boom must work out from the truck. The compact 6×4 chassis moves easily between dispersed pour locations on linear infrastructure projects.

General construction and foundations

Raft foundations, ground slabs, industrial floors and structural frames suit the balance of 150 m³/h output and a 5-section boom, fed through the 260 × 1800 mm cylinders and DN125 line.

Standard and high-strength mixes

At 10.7 MPa concrete pressure with an S-valve and a 700 L hopper, the TP43RZ5 pumps standard and high-strength mixes reliably across mid-rise and infrastructure work.

FAQs

How many floors can the TP43RZ5 reach?

Its 43 m vertical reach places concrete directly on roughly 13 storeys from a single set-up, depending on floor-to-floor height and where the truck can stand. For taller buildings, the concrete pump truck feeds a riser pipeline to a placing boom on the upper floors, or a longer-reach model is used.

What is the difference between the TP43RZ5 and the RZ6 models?

The TP43RZ5 is the mid-range boom pump: a 5-section RZ boom reaching 43 m, with 150 m³/h output on a Sitrak 6×4 chassis. The RZ6 models — the 49 m TP49RZ6, 56 m TP56RZ6 and 62.5 m TP63RZ6 — use a 6-section boom, higher 180 m³/h output and an 8×4 chassis for high-rise work. Choose the TP43RZ5 when 43 m of reach is enough and a lighter, more economical truck suits the job.

What chassis does it come on?

The TP43RZ5 is supplied on a Sitrak 6×4 chassis with a 286/297 kW engine, in Euro III–V. The 6×4 configuration keeps the truck lighter and more manoeuvrable than the 8×4 high-rise models, which suits mid-rise and infrastructure work and markets with tighter axle-load limits.

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

Yes. With 10.7 MPa concrete pressure, an S-valve, 260 × 1800 mm cylinders and a DN125 delivery line, this 43 m pump truck pumps standard and high-strength mixes reliably. For the most demanding high-pressure mixes on tall structures, the higher-pressure RZ6 models add margin.

Is it remote-controlled?

Yes — the PLC/CAN-BUS electronic control system operates with both wireless and cable remote control, so one operator can position the boom from the pour point. Automatic centralised lubrication and a high-pressure wash-down system cut daily maintenance time.

What is included, and how is it delivered?

The standard unit includes the boom pump on the Sitrak 6×4 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 TP43RZ5 fits in the TRUEMAX boom-pump range

The TP43RZ5 is the mid-range concrete pump truck in the TRUEMAX TP range, which spans the compact 25 m TP25M4 up to the 62.5 m TP63RZ6. As a 43 m boom pump it sits a step above the 38 m TP38RZ5 — the two share the same 5-section roll-fold boom and 150 m³/h pumping system — and below the 6-section RZ6 high-rise models such as the 49 m TP49RZ6. Where the RZ6 machines target towers of 15 storeys and up, the 43-metre TP43RZ5 covers the mid-rise and infrastructure work at about 13 storeys, on a lighter and more economical 6×4 chassis. The choice between a 38 m, 43 m or 49 m pump truck comes down to the reach your typical pour needs.

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 TP43RZ5 both pumps and places in a single machine — it drives itself to site, sets up on its outriggers, 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 buildings taller than the boom can reach, contractors pair a stationary concrete pump with a concrete placing boom: the pump sends concrete up a riser pipeline, and the placing boom distributes it across each floor.

Truck-mounted boom pump vs line pump

A boom pump (called a concrete pumper in North America, and a concrete lorry pump in the UK) is the right tool when you need height, speed and reach over obstacles in open pours. A line pump — including the truck-mounted line pump — is the better choice for tight access, long horizontal distances at ground level, smaller pours, or a lower budget. Many contractors run both: a mid-range boom pump like the TP43RZ5 for mid-rise and infrastructure work, and a line pump for confined or long-distance jobs.
