SINOTRUK-HOWO N7 Flagship Chassis for Concrete Mixer Trucks — 12 m³, Euro V, 100 km/h

The SINOTRUK-HOWO N7 is the flagship lower-part option in the TRUEMAX concrete mixer truck range — built on SINOTRUK's premium HOWO N7 chassis (ZZ1317N466JE1) for the developed markets and long-haul duty cycles that the mainstream and light chassis are not built for. It runs the MC11.44-50 engine at 440 kW in a single Euro V specification — the next-generation MC11 platform rather than the proven WP10 used on the mainstream chassis — pulls a fixed 50,000 kg rated load on an 8×4 four-axle drive, and travels at up to 100 km/h on 315/80R22.5 tubeless radial tyres. It is the only TRUEMAX mixer-truck chassis configured for these motorway-grade specifications, and it is paired with the 12 m³ CTM12 upper part rather than offered across a payload range.

That single-configuration approach is deliberate. The HOWO N7 chassis exists to serve operators who require Euro V emissions, a motorway-grade vehicle and modern engine technology — typical specifications for European, Middle-Eastern, Latin-American and Australian RMC fleets where the mainstream Euro II–V SINOTRUK platform is fine for the lower emission bands but lacks the developed-market refinement at the top. The 100 km/h top speed, against 90 km/h on the other two chassis, opens long-distance ready-mix routes that the slower trucks lengthen too much; the 22.5" tubeless radial wheels are the standard on modern European and Australian trucks, against the 20" tube tyres on the other chassis. The truck is built and tested at the TRUEMAX factory in Haining to ISO 9001:2015 and CE standards, with the same one-stop after-sales programme — three-minute response, 24-hour solutions, remote intelligent service — within a line exported to more than 120 countries.

1. Euro V emissions in a single specification — Built for Euro V from the ground up rather than as the top of a multi-tier emission band, so the engine, after-treatment, fuel system and electronics are all matched to that standard. For markets that require Euro V, this is the chassis to specify rather than the mainstream platform's Euro V option.

2. MC11.44-50 engine, 440 kW — The MC11 is SINOTRUK's modern heavy-truck engine platform — a generation newer than the WP10 used on the mainstream chassis. 440 kW gives generous power reserve for a fully loaded 12 m³ mixer at motorway speed, on long grades, and over sustained long-haul running.

3. 100 km/h motorway top speed — Top speed of 100 km/h against 90 km/h on the other two TRUEMAX chassis — meaningful for long-haul ready-mix routes. An hour at 100 km/h covers 100 km; at 90 km/h it covers 90 — across a working day, the speed difference adds delivery range without changing the duty cycle.

4. 8×4 four-axle layout, 50,000 kg rated — 8×4 four-axle drive spreads the heavy 50,000 kg rated load across more axles for axle-load compliance on European-style roads, gives better braking and handling under heavy load, and stays within typical European total-weight limits at full load.

5. 315/80R22.5 tubeless radial tyres — 22.5" tubeless radial truck tyres are the standard on modern European, Middle-Eastern and Australian trucks — better fuel economy at motorway speed than the 20" tube tyres on the other chassis, easier roadside repair (no inner tube), and longer service life under sustained high-speed running.

6. Built for the 12 m³ CTM12 upper part — Matched to the TRUEMAX CTM12 — 18.4 m³ geometric drum and 12 m³ rated payload of concrete — rather than offered across a drum-size range. The whole vehicle (chassis + upper part + sub-frame + hydraulics + water tank + chute) is built up at the TRUEMAX works around this single, optimised pairing.

7. Air-bag seat and air-conditioned cab as standard — Cab equipment includes an air-bag driver's seat and air conditioning, the same standard fitment as the mainstream and light chassis but in a higher cab-quality grade matched to the HOWO N7 chassis line. Long shifts on motorway routes make cab comfort a real operational factor.

8. Customisable to destination market — The standard build is the configuration above, but the chassis is customisable on request — transmission selection, axle ratio, fuel-tank size, electrical and lighting kit for the destination market, and regional homologation. Tell us the destination and intended duty cycle and we will configure accordingly.

Dimensions & Working Range

The HOWO N7 chassis is supplied to TRUEMAX as bare chassis-cab, on which the CTM12 upper part — drum, sub-frame, hydraulic system, water tank and discharge chute — is built up at the TRUEMAX factory. Overall vehicle dimensions are 10,600 × 2,496 × 3,990 mm with the CTM12 drum fitted — within standard European road-vehicle envelope limits. The Euro V configuration adds an AdBlue (DEF) tank for selective catalytic reduction, alongside the diesel tank and the upper part's water tank. Read the dimensional drawing together with the CTM12 upper-part drum drawing when planning batching-plant loading and motorway-route clearances.

Applications

The HOWO N7 chassis is the lower-part platform for the developed-market end of the TRUEMAX mixer-truck range — sized to long-haul ready-mix and high-emission-standard regulatory environments.

Developed-market RMC fleets requiring Euro V

European, Middle-Eastern, Australian and South-American RMC operators in countries that require Euro V emissions specify Euro V chassis as standard. The HOWO N7's single Euro V configuration is built for this — the engine, after-treatment, fuel system and electronics are all matched to the standard rather than fitted as an option on top of a multi-tier band.

Long-haul ready-mix routes

Routes between regional batching plants and outlying sites — 30, 50, sometimes 80 kilometres each way — gain real time from the 100 km/h top speed and the motorway-grade running gear. Where a mainstream truck would do three round trips a day on such a route, the N7 may add a fourth.

Major motorway, port and airport works

Major motorway upgrades, port construction and airport pavement work draw on 12 m³ trucks for sustained high-volume supply. The 50,000 kg rated 8×4, the 440 kW MC11 engine and the motorway-grade tyres are matched to this duty cycle better than the mainstream platform.

Operators standardising on a single premium platform

RMC operators running one chassis platform across a fleet — for parts inventory, driver familiarisation and service-network consistency — and standardising on a premium grade specify the HOWO N7 across the 12 m³ trucks in the fleet. For mixed-size fleets, the mainstream SINOTRUK chassis covers 6–10 m³ alongside the N7's 12 m³.

FAQs

HOWO N7 or the mainstream SINOTRUK chassis — which should I choose at 12 m³?

Both can carry a 12 m³ drum, but the trucks are configured differently. The mainstream SINOTRUK 8×4 (ZZ1317 chassis, WP10 380 kW engine) covers Euro II to Euro V at 90 km/h on 20" tube tyres — broad market reach, proven hardware, lower price. The HOWO N7 (ZZ1317N466JE1 chassis, MC11 440 kW engine) is single-spec Euro V at 100 km/h on 22.5" tubeless radial tyres — sized for developed-market operators that need the higher emission standard, motorway speed and premium running gear. Specify N7 when those features are required by your market or duty cycle; specify the mainstream platform when they are not.

What is the MC11 engine, and how does it differ from the WP10?

The MC11.44-50 is SINOTRUK's modern 11-litre heavy-truck engine, developed on a newer platform than the proven WP10 used on the mainstream chassis. Practical differences for an operator: more power (440 kW versus 340/380 kW on the WP10), Euro V emissions in a clean single-tier engineering rather than as the top of a wider band, lower noise at motorway speed, and electronic engine management throughout. The trade-off is a higher acquisition price and more sophisticated diagnostics.

Why is the top speed 100 km/h instead of 90?

Because the HOWO N7 is engineered as a motorway-grade truck rather than as a regional one. The driveline, brakes, suspension and tyres are all rated for sustained running at 100 km/h fully loaded — meaningful on long-distance ready-mix routes between regional batching plants and outlying sites. The mainstream and light chassis are rated to 90 km/h, which is the right answer for shorter-haul urban and regional duty.

Why 22.5" tubeless radial tyres instead of 20" tube tyres?

Three reasons matter to fleet operators. Fuel economy is better on radial tyres at motorway speed than on tube tyres — meaningful on long-distance trucks running thousands of kilometres a year. Roadside repair is faster on tubeless tyres because no inner tube needs to be removed. And 22.5" is the standard truck wheel size on modern European, Middle-Eastern and Australian trucks — service support and replacement tyre availability are simpler in those markets.

Is the 8×4 layout fixed, or can other drive types be specified?

8×4 four-axle drive is the standard HOWO N7 configuration in the brochure, sized to the 50,000 kg rated load. Other drive layouts on the HOWO N7 chassis can be customised on request — tell us the destination market and duty cycle, and we will confirm whether a 6×4 N7 variant is available for your application. For routine 6×4 work, the mainstream SINOTRUK ZZ1257 6×4 chassis is the standard answer.

What is AdBlue, and where does it fit on the truck?

AdBlue (also called Diesel Exhaust Fluid, DEF) is the urea-based fluid used by the Euro V engine's selective catalytic reduction (SCR) system to reduce NOx emissions. The HOWO N7 chassis includes an AdBlue tank alongside the diesel tank — capacity is sized to provide refill intervals matched to the diesel tank. Operators in markets new to Euro V should plan AdBlue supply, but it is widely available wherever Euro V trucks are running.

Can it carry drums other than the CTM12?

The standard pairing is the CTM12 — 18.4 m³ geometric drum and 12 m³ rated payload — which sits well within the chassis's 50,000 kg rated load. The 14 m³ CTM14 can be specified on the N7 platform on request and confirmed against the chassis's load and axle-distribution limits. For smaller drums (CTM3–CTM10), the mainstream SINOTRUK 6×4 or the light HOWO 7 4×2 are the right chassis choices — using an 8×4 Euro V chassis for a 5 m³ drum is over-specification.

What after-sales support comes with the truck?

TRUEMAX supplies the chassis and the CTM12 upper part as one assembled vehicle, with one warranty and one after-sales channel. Pre-sale consultation, on-site commissioning of the assembled truck, driver and operator training, three-minute service response, 24-hour solutions, and a remote intelligent service with self-diagnosis. SINOTRUK's service network operates in most TRUEMAX export markets, including the developed markets the N7 is built for; MC11 engine service is part of that network.

Where the HOWO N7 sits in the TRUEMAX mixer-truck range

The TRUEMAX concrete mixer truck is offered on three SINOTRUK group chassis platforms covering the entire payload range from 3 m³ to 14 m³. The light SINOTRUK-HOWO 7 (ZZ5128F3915, 4×2, Yuchai 102 kW, Euro II) is the city-truck platform for 3–5 m³ drums. The mainstream SINOTRUK chassis (ZZ1257 6×4 / ZZ1317 8×4, WP10 340/380 kW, Euro II–V) is the workhorse platform for 6–14 m³ drums. The HOWO N7 shown on this page is the flagship platform — 8×4, MC11 440 kW, Euro V, 100 km/h, 22.5" tubeless radial — built for 12 m³ drums in developed-market and motorway service. Picking the chassis comes down to which drum size, which market and which operating profile.

When the flagship chassis is the right call

For most TRUEMAX mixer-truck supplies, the mainstream SINOTRUK chassis is the right answer — it covers Euro II to Euro V, both popular drive layouts, and the whole 6–14 m³ payload range from one platform. The flagship HOWO N7 earns its place in three situations. First, when the destination market regulates Euro V from day one — buying a chassis engineered for Euro V is technically cleaner than fitting the standard as the top of a multi-tier band. Second, when the route plan includes long-distance ready-mix runs at motorway speed, where the 100 km/h N7 covers more ground per day than the 90 km/h mainstream. Third, when the operator standardises on a premium platform across the fleet for parts, service and driver familiarity. Outside those situations, the mainstream chassis is the more cost-effective pick.

Chassis and upper part as one integrated vehicle

A TRUEMAX mixer truck is sold as one finished vehicle, with the chassis (lower part) and the drum-and-hydraulics (upper part) integrated at the TRUEMAX works rather than shipped separately for site assembly. The HOWO N7 is delivered with the CTM12 upper part already built up — sub-frame, drum, hydraulic system, water tank and discharge chute installed and tested. That gives the operator one assembled vehicle, one warranty channel and one set of operating manuals, regardless of which chassis they specified. The combined upper-part product page documents the drum-side hardware shared across the CTM range.
