Truck mixers and truck-mounted concrete pumps: EN 12609, EN 12001, chassis and electric mixers

A truck mixer is a mixing drum mounted on a truck or trailer to carry ready-mixed concrete; a truck-mounted concrete pump carries a pump and, usually, a folding placing boom. Europe sets their safety requirements in two standards, EN 12609 for the mixer and EN 12001 for the pump and boom, and neither covers the truck underneath. The chassis comes from the truck makers and the drum or pump from specialist body builders. This page sets out what the standards cover, how EU type approval names the vehicles, and what makers publish for concrete work. It does not rank or recommend any of them.

EN 12609 for the mixer, EN 12001 for the pump

EN 12609:2021, Truck mixers — Safety requirements, dated January 2021 and prepared by CEN/TC 151, covers truck mixers and the interface between the mixing unit and the truck or trailer, but not the truck or trailer itself; a note names category N3 or O4 carriers. It leaves out additional equipment such as conveyor belts, mortar pumps, concrete pumps and placing booms, operation in tunnels, self-loading mixers, front-discharge mixers, mixing units with articulated steering, drum cleaning systems and the energy source. Its contents include the power transmission from the drive source to the drum drive, the exhaust of an auxiliary engine, and noise measurement for mixers driven and not driven by the truck engine.

EN 12001:2012, Conveying, spraying and placing machines for concrete and mortar — Safety requirements, from the same committee, supersedes the 2003+A1:2009 edition. It covers concrete pumps, placing booms and delivery line systems, stationary or mobile. It defines a concrete pump as a machine that can be mounted on a truck, trailer or special-purpose vehicle and should only be operated in a stationary position, and adds that some machines it covers present risks very similar to mobile cranes. It does not cover machines that move while conveying, cabins, extra functions such as mixing or crane work, or operation in tunnels.

Both are harmonised standards under the current Machinery Directive: Implementing Decision (EU) 2022/621 added EN 12609:2021, and Implementing Decision (EU) 2023/1586 lists both; we did not check later amendments to that list. The Machinery Regulation (EU) 2023/1230 applies from 20 January 2027. ISO published a separate safety standard for truck mixers, ISO 19711-2:2023, whose foreword names only the ISO committee; we found no European adoption of it, and EN 12609:2021 remains the European standard.

Type approval: bodywork codes 15 and 16

Regulation (EU) 2018/858, as published in 2018, does not list mixers or pump trucks among its special purpose vehicles. They appear among the two-digit supplements to the bodywork code of an N-category vehicle such as a lorry or a chassis-cab: “15 Concrete mixer” and “16 Concrete pump vehicle”. The same list has refuse collection vehicles under 18; see refuse collection vehicles. Fire engines are listed under 31; see fire engines on truck chassis. Tippers are listed under 10; see tipper trucks.

What the chassis has to offer

The drum is turned by a power take-off, and the makers’ documents describe the options. DAF offers 68 PTO options, from clutch-independent engine-driven PTOs at the 11 o’clock and 1 o’clock positions to clutch-dependent gearbox PTOs, and lists mixers among the five applications of its factory body preparations. Scania’s mixer booklet, built around a P 460 B8x4NZ, lists an engine PTO at the rear end of the engine, a clutch-dependent gearbox PTO that works only with the clutch pedal released, frame reinforcements for the rear overhang and a 50 mm hole pattern for the body. Iveco gives its T-Way a sandwich PTO of up to 2,300 Nm.

Body builders state their own requirements. CIFA’s chassis specification of September 2025 lists, for its SL 8 and SL 9 mixers on a four-axle 32 t truck, a minimum wheelbase of 4,250 to 4,350 mm depending on the chassis, and the torque its drum drive needs from the engine PTO: 600 Nm on the Arocs, 750 Nm on the F-Line, 830 Nm on the XDC and XFC, 900 Nm on the TGS and on the X-Way and T-Way, and 1,000 Nm on the FMX. It allows a chassis height of up to 1,200 mm.

Payload is the other constraint. Renault Trucks says a diesel truck with a conventional mixer can carry up to 8 m³ of concrete in most European countries, depending on national regulations, and that battery weight reduces this capacity. It gives the tare weight of its C XLOAD 8x4 mixer chassis as 9,200 kg, for a 7.5 to 8 m³ mixer, on its Middle East site.

Chassis the makers offer for mixers and pumps

In alphabetical order, as each maker presents it:

• DAF. The XDC and XFC construction trucks come with two, three or four axles, which DAF calls the ideal basis for tippers, concrete mixers and hook lifts, with a 25° approach angle and 33 to 39 cm of ground clearance. In January 2026 DAF added electric construction models: the 6x4 FAT, with a 29 t GVW, which it calls more than suitable for tipper and concrete mixer work, and a 650 V e-PTO of 25, 60 or 100 kW as an option.
• Ford Trucks. Ford’s Turkish site lists mixer chassis — the 4145M (8x4, 5,100 mm wheelbase) and 3545M (6x4, 3,800 mm), both with a 12.7-litre 450 PS engine — and, under its pump series, the 4145P (8x4, 5,100 mm), 3545P (6x4, 4,500 mm) and 1833P (4x2, 4,750 mm, 9-litre 330 PS). In 2018 Ford said its 8x4 4142P, with 5,100 or 6,000 mm wheelbases, took 42 and 47 m concrete pump bodies.
• Iveco. The X-Way is presented for concrete mixers at 32 t GVW as an 8x4 with 360 to 540 hp, an automated gearbox, clutch-dependent and clutch-independent PTOs and “concrete mixer packs (Super-Loader)”; its 8x4 wheelbases run from 3,300 to 5,100 mm (one front axle) and 4,250 to 5,820 mm (two front axles). The T-Way lists “Mixer” among its missions.
• MAN. MAN presents construction vehicles and truck mixers with the switchable HydroDrive front-wheel drive and all-wheel drive as 4x4, 6x6, 8x6 or 8x8, and a cab 2,240 mm wide. It says the frame of its current generation is level along its whole upper edge, which makes the body builder’s work easier, and names truck mixers and concrete pumps among the construction applications of the TGS, at 18 to 51 t gross train weight.
• Mercedes-Benz. The Arocs comes in configurations from 4x2 to 8x8/4, with a Hydraulic Auxiliary Drive that supplies up to 40 kW per front wheel at up to 450 bar. The electric eArocs 400 is an 8x4/4 with wheelbases from 4,550 to 5,450 mm, a technical GVW of 37 or 44 t and 414 kWh of LFP batteries; Mercedes-Benz gives it a range of up to 200 km as a concrete mixer, from an internal simulation of a 32 t 8x4 mixer with eight hours of drum operation at 20 °C. The low-entry Econic is also offered as a mixer, for example as a 3235 L 8x4.
• Renault Trucks. Renault builds its mixer chassis on the C range, with options designed for the drums of the market’s two largest makers and “high-capacity rear motor drives for concrete pumps”. Its electric E-Tech C 10x4, with a fully electric Schwing Stetter mixer powered from the truck’s batteries, carries up to 10 m³ and is sold in Switzerland, Ireland, the Netherlands, Luxembourg, Finland and Slovakia, where five-axle rigids may run at up to 42 t.
• Scania. Scania presents mixer trucks and concrete pump trucks for construction, and says a pump truck’s powertrain must suit the length and height of the boom and the speed and volume of the concrete flow. A customer story from 2023 describes a five-axle Scania XT carrying a 60 m concrete pump.
• Volvo. The FMX Electric has a GCW of up to 65 t, rigid layouts from 4x2 to 8x4 and two PTOs: an electrical one at 30, 60 or 90 kW and a clutch-independent transmission PTO that can run while the truck is charging or driving, which Volvo calls great for mixers.

Electric mixers

Battery figures are not always given on the same basis; see installed vs usable battery capacity. Volvo’s FMX Electric page gives both “two to six battery packs” and, in its specification table, 360 to 540 kWh from four to six batteries.

Bodies and booms

Body builders publish drum volumes, weights and boom reaches:

• CIFA builds truck mixers of 4 to 15 m³ that, it says, “can be mounted on any truck chassis brand and configuration, powered by either PTO or an auxiliary engine”. Its Energya E9 and E10, of 9 and 10 m³, turn the drum with an electric motor, so that the drum is no longer tied to the vehicle’s power take-off. Its truck-mounted pumps run from the K20L, with a 20 m boom, to the K67H with 66.1 m, on chassis from 4x2 to 12x4.
• Liebherr lists HTM mixers with a hydraulic drum drive from 5 to 12 m³ nominal; for the current generation it gives weights of 3,650 to 4,440 kg for 8 to 12 m³ “for basic unit with chassis power take-off (PTO)”. At bauma 2025 it showed a conventional HTM 905 on an all-electric Volvo tridem chassis, driven through an electro-mechanical power take-off. Its truck-mounted pumps reach 23.7 to 49.1 m vertically and pump 138 to 167 m³/h.
• Putzmeister publishes truck-mounted pumps from the M20 to the M63, with vertical reaches of 19.5 to 62.1 m; its M38-5 data sheet gives a gross weight of up to 26 t on three axles and the M47-5 sheet up to 32 t. Its P 7 to P 12 mixers hold 7 to 12 m³, and the iONTRON eMixer puts a 9 m³ electric body on a SANY 8x4 electric truck with a 350 kWh battery.
• Schwing Stetter lists AM mixers from 6 to 15 m³ and says its UltraEco carries 8 m³ of concrete at a permissible total weight of 32 t on a weight-optimised Euro 6 8x4. Its S-series pumps reach 19.40 to 64.25 m vertically and pump up to 162 m³/h, on example chassis from a 4x2 for the S 20 to a 12x4 for the S 65 SXF. The S 36 X RaZor electric, which Schwing calls its first fully electric truck-mounted pump, charges its batteries from site power during pumping breaks.
