TP43RZ5B Truck-Mounted Concrete Boom Pump — 43 m

The TP43RZ5B truck-mounted boom pump features a 5-section RZ roll-fold boom with a 43 m vertical reach and 39 m horizontal reach, suitable for mid-rise buildings, highways, bridges, and general construction. The pumping system provides a maximum theoretical output of 170 m³/h at 5.9 MPa pressure, managed by a PLC/CAN-BUS electronic control system with wireless remote operation.

Mounted on a Sitrak 6×4 chassis with a total weight of 33,800 kg, the TP43RZ5B offers a stable outrigger base while maintaining a relatively compact footprint compared to 8×4 models. The boom structure is fabricated from imported high-strength low-alloy steel with a yield strength exceeding 900 MPa, and undergoes 100% non-destructive weld testing.

1. Reliable power transmission — Utilizes established transmission components for stable power delivery.

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, allowing setup in narrow site conditions.

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

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

6. Large water tank + high-pressure cleaner — Facilitates rapid post-pour maintenance.

7. Automatic centralised lubrication — Services main friction points to maintain equipment longevity.

8. PLC/CAN-BUS electronic control — Integrates with the chassis engine and supports remote diagnostics.

Dimensions & Working Range

The working-range diagram shows the boom’s reach envelope: the heights and horizontal distances the TP43RZ5B 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 TP43RZ5B 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, the TP43RZ5B places concrete directly on structures up to approximately 13 storeys without a separate riser line, serving mid-rise residential and commercial applications.

Roads, highways and bridges

The 39 m horizontal reach and ±270° slewing support road and bridge construction, deck pours, and foundation work where extended lateral placement is required. The 6×4 chassis provides mobility between dispersed pour locations on linear infrastructure projects.

General construction and foundations

The 170 m³/h output capacity and 5-section boom, fed through 260 × 1800 mm concrete cylinders and a DN125 delivery line, handle raft foundations, ground slabs, industrial floors, and structural frames.

Standard and high-strength mixes

Operating at 5.9 MPa concrete pressure with an S-valve and a 700 L hopper, the unit pumps standard concrete mixes reliably across mid-rise and infrastructure developments.

FAQs

How many floors can the TP43RZ5B reach?

The 43 m vertical reach allows direct concrete placement on structures up to approximately 13 storeys from a single setup, depending on floor-to-floor height and chassis positioning. For taller structures, a stationary pump feeds a riser pipeline to a placing boom, or a longer-reach boom pump is utilized.

What is the difference between the TP43RZ5B and the RZ6 models?

The TP43RZ5B is a mid-range model featuring a 5-section RZ boom with a 43 m reach, delivering 170 m³/h output on a Sitrak 6×4 chassis. The RZ6 models, such as the 49 m TP49RZ6, 56 m TP56RZ6, and 62.1 m TP63RZ6, utilize a 6-section boom, provide 180 m³/h output, and mount on an 8×4 chassis for high-rise applications.

What chassis does it come on?

The TP43RZ5B is mounted on a Sitrak 6×4 chassis equipped with a 297 kW engine, compliant with Euro III–V emission standards. The 6×4 configuration maintains a lower weight and higher maneuverability compared to 8×4 models, aligning with mid-rise project requirements and tighter axle-load limits.

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

Yes. Operating at 5.9 MPa concrete pressure with an S-valve, 260 × 1800 mm cylinders, and a DN125 delivery line, the unit handles standard and structural concrete mixes. For highly demanding high-pressure mixes on taller structures, the RZ6 models with 12 MPa capability provide additional margin.

Is it remote-controlled?

Yes — the PLC/CAN-BUS electronic control system supports both wireless and cable remote control, enabling operators to position the boom directly from the pour point. Automatic centralized lubrication and a high-pressure wash-down system streamline daily maintenance.

What is included, and how is it delivered?

The standard configuration includes the boom pump mounted on the Sitrak 6×4 chassis, remote controls, and the wash-down system. Terms for delivery, packing, shipping (FOB / CIF), spare parts kits, installation, commissioning, and operator training are calculated per project.

Where the TP43RZ5B fits in the boom-pump range

The TP43RZ5B functions as the mid-range concrete pump truck in the TP series, which extends from the compact 24.2 m TP25M4 to the 62.1 m TP63RZ6. Positioned above the 38 m TP38RZ5, it utilizes a 5-section RZ roll-fold boom and a 170 m³/h pumping system on a 6×4 chassis. In contrast, the 6-section RZ6 models, such as the 49 m TP49RZ6, target structures of 15 storeys and above, utilizing an 8×4 chassis. The TP43RZ5B addresses mid-rise and infrastructure requirements at approximately 13 storeys, utilizing a lighter 6×4 platform.

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

A truck-mounted boom pump serves as the placement equipment in the concrete delivery chain. Concrete is produced at a batching plant, transported by a truck mixer, and placed by the pump. The TP43RZ5B executes both pumping and placement in a single unit, providing rapid setup and direct delivery to the pour area. For structures exceeding the boom's vertical reach, operations integrate a stationary concrete pump with a concrete placing boom to distribute material across upper floors.

Truck-mounted boom pump vs line pump

A boom pump efficiently clears obstacles and requires minimal setup time for open pours. A line pump — including the truck-mounted line pump — provides a practical alternative for tight access zones, extensive horizontal distances at ground level, or constrained budgets. Contractors frequently utilize both formats based on site requirements: a mid-range boom pump like the TP43RZ5B for mid-rise and infrastructure work, and a line pump for confined or long-distance applications.
