TP38RZ5 Truck-Mounted Concrete Boom Pump — 38 m

The TP38RZ5 is the compact end of the mid-range in the TRUEMAX truck-mounted boom pump line-up. Its 5-section RZ roll-fold boom reaches 38 m vertically and 34 m horizontally, placing concrete directly across roughly 12 storeys from a single set-up. That makes this 38 m concrete pump a good fit for low- to mid-rise buildings, roads, bridges and general construction, where a 38-metre boom does the job and a lighter, more manoeuvrable truck is an advantage on busy or constrained sites. 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.

On a single Sitrak 6×4 chassis at 29,300 kg, the TP38RZ5 is the lightest boom pump in the RZ series — easy to move between jobs and to set up where space is tight. 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 TP38RZ5 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 TP38RZ5 is built for the high-volume, lower-rise end of the market — the buildings, roads and general pours where 38 m of reach is the right amount and a compact truck moves and sets up quickly.

Low- and mid-rise buildings

With 38 m of vertical reach, this 38 m boom pump places concrete directly on roughly 12 storeys without a separate riser line — covering houses, low-rise blocks and the many mid-rise buildings that make up everyday construction.

Roads, highways and bridges

The 34 m horizontal reach and ±270° slewing suit road, bridge and deck pours where the boom must reach out from the truck, and the light 6×4 chassis moves easily between dispersed pour points on linear projects.

General construction and foundations

Ground slabs, raft foundations, 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 TP38RZ5 pumps standard and high-strength mixes reliably across low-rise and infrastructure work.

FAQs

How many floors can the TP38RZ5 reach?

Its 38 m vertical reach places concrete directly on roughly 12 storeys from a single set-up, depending on floor-to-floor height and where the truck can stand. For taller buildings, a longer-reach model is used, or the pump feeds a riser pipeline to a placing boom on the upper floors.

What is the difference between the TP38RZ5 and the TP43RZ5?

They share the same platform — a 5-section RZ boom, 150 m³/h pumping system and Sitrak 6×4 chassis. The difference is reach and size: the TP38RZ5 reaches 38 m (about 12 storeys) and weighs 29,300 kg, while the TP43RZ5 reaches 43 m (about 13 storeys) at 32,850 kg. Choose the 38 m model for lighter, more compact work and the 43 m when you need the extra reach.

What chassis does it come on?

The TP38RZ5 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 light and manoeuvrable, which suits low- to 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 38 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 TP38RZ5 fits in the TRUEMAX boom-pump range

The TP38RZ5 is the compact mid-range concrete pump truck in the TRUEMAX TP range, which spans the 24.2 m TP25M4 up to the 62.5 m TP63RZ6. As a 38 m boom pump it is the entry point to the 5-section RZ platform: it shares the same boom design and 150 m³/h pumping system as the 43 m TP43RZ5, one size up, while the 6-section RZ6 models such as the 49 m TP49RZ6 step up to 180 m³/h and an 8×4 chassis for high-rise work. Below it, the 24.2 m TP25M4 is the compact city pump for the smallest sites. The choice between a 25 m, 38 m or 43 m pump truck comes down to the reach and output 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 TP38RZ5 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 compact boom pump like the TP38RZ5 for low- and mid-rise work, and a line pump for confined or long-distance jobs.
