Here is the number most mixer buyers get wrong, and it is worth putting at the top: the drum volume is not the load limit, the rated load is. On this range the drum is rated between 4.03 and 4.5 cubic metres, but rated load runs from 8.87 to 9.87 tonnes — and ready-mix concrete weighs roughly 2.4 tonnes per cubic metre. Fill a 4.5 cubic metre drum to the brim and you are carrying about 10.8 tonnes of concrete, which puts you over the rating on every variant here. The Foton Auman ETX 9 6x4 concrete mixer truck is listed at 43,900 USD across five configurations, and understanding that arithmetic is what turns a cheap mixer into a legal one.
The legal limit is set by mass, not volume. Rated load is 9.87 tonnes on the BJ5253GJB-AB and 9.835 tonnes on the BJ5253GJB-XL, falling to 8.87 tonnes on the AC versions, which carry a 16-tonne kerb weight against 15 tonnes on the others. That one-tonne difference is not trivial on a mixer — it is roughly half a cubic metre of concrete per trip, every trip, for the life of the truck.
For sites with weighbridges, specify the drum against your real batch weight rather than the largest drum on the sheet. If your plant routinely batches to 4.5 cubic metres and your market enforces axle limits, the honest answer is that you need either a lighter drum or a higher-rated chassis — and it is far better to discover that in the quotation than at a weighbridge.
"A 4.5 m³ drum full of concrete is about 10.8 tonnes. The best-rated variant here is 9.87. Specify against the weighbridge, not the brochure."
Water supply is by air pressure across all five variants, which is the simple, robust answer for a mixer: no pump to fail at the pour, and easy wash-down at the end of the shift. Ask your dealer to confirm the water tank capacity, because it is not published and it decides how much wash-down you can do before returning to the plant.
All five are 6x4, all run ten tyres, and all are limited to 85 km/h, which tells you this is a site-and-plant machine rather than a long-haul one. Beyond that the differences are real:
Note the price inversion worth thinking about: the two cheapest variants carry the least, and the most expensive is only 3,900 USD more than the entry truck while adding 35 hp and three gears. On a machine doing dozens of pours a week, that gap is small against the uptime it buys.
The 340 hp Foton Cummins ISGe5-340, at 10.5 litres, is the lighter, simpler option and is paired with a Fast nine-speed. The Weichai WP12.375E50, at 11.596 litres, is offered with either a Fast 9JSD180 or a 12JSD180.
The twelve-speed is worth having if your routine includes steep site access ramps or stop-start city batching, because it keeps the engine in its working range with less clutch work — and clutch life is a genuine budget line on a mixer that moves off loaded dozens of times a day. For flat urban runs on a fixed batching-plant circuit, the nine-speed with the 340 hp engine is usually the cheaper and lower-maintenance choice.
Which engine brand you take should be decided by support, not by badge. Both are common-rail diesels, and common rail depends on clean, low-sulphur fuel — so fuel quality at your depots is part of the decision. Ask your dealer which of the two has parts stock and trained technicians on your route, and let that settle it.
Three ratios appear across the range: 4.8 on the AB, 5.26 on the XL nine-speed and the Weichai AC, and 4.76 on the XL twelve-speed and the Cummins AC. The taller 5.26 gives more crawl for loaded starts on soft ground; 4.76 and 4.8 trade a little of that for road speed between plant and site. On a fixed urban batching circuit the difference is modest; on steep or unconsolidated site access it is the difference between a clean pull-away and slipping the clutch.
Suspension varies too: the AB and the Cummins AC list a wide range of spring leaf options including 10/12, 11/14, 9/12, 3/5, 3/4 and 2/4 configurations, while the XL and Weichai AC are listed at 9/12 or 10/12. Ask which is fitted as delivered, because spring pack choice affects both ride and how the truck sits under a full drum — and a mixer that sits badly wears tyres unevenly.
Tyres are ten in number, with sizes including 11.00-20 18PR, 11.00R20 18PR, 12.00-20 16PR and 18PR, and 12.00R20 16PR depending on variant. Note the mix of tube-type and radial: check which you are getting, because the retread and repair economics differ, especially if your sites are remote.
"Three axle ratios, three engines, two gearboxes, three drum sizes. There is no single right answer here — only the right answer for your ramps and your batch weights."
Most variants are listed as China V, while the two WP12.375E50 models sit at Beijing V, a tighter local standard. Neither is Euro VI, so check whether your market accepts Euro V-level homologation before committing — several import markets now require Euro VI for new registrations. This is the single most common reason an otherwise sound purchase becomes a stranded asset, and it is a paperwork question with a definite answer if you ask early enough.
Fuel quality matters alongside it. Common-rail injection depends on clean, low-sulphur diesel, and if your depots cannot guarantee that, no amount of engine choice will save the injectors. Send the dealer your destination and let them advise which of the five configurations is registrable there.
At 43,900 USD for the entry configuration, the commercial case is a Cummins or Weichai driveline, a Fast gearbox and a 16-tonne Mercedes-pattern rear axle at a price well below a European equivalent. The counter-argument is residual value and service coverage in your market, neither of which appears in this pack — ask both before committing to a fleet quantity. The ETX 9 mixer truck page is where you confirm which configurations are available on the current build slot.
The drum is rated at 4.03 to 4.5 cubic metres depending on variant, but the legal limit is set by mass. Rated load is 9.87 tonnes on the AB and 9.835 tonnes on the XL, falling to 8.87 tonnes on the AC versions with their 16-tonne kerb weight. Ready-mix concrete weighs roughly 2.4 tonnes per cubic metre, so a full 4.5 m³ drum would put even the AB over its rated figure. For sites with weighbridges, specify the drum against your real batch weight.
The 340 hp Foton Cummins ISGe5-340 at 10.5 litres is the lighter, simpler option and is paired with a Fast nine-speed. The Weichai WP12.375E50 at 11.596 litres comes with either a Fast 9JSD180 or a 12JSD180. The twelve-speed is worth having for steep site access ramps or stop-start city batching; for flat urban runs on a fixed plant circuit, the nine-speed with the 340 hp engine is usually cheaper and lower-maintenance.
Most variants are listed as China V, while the two WP12.375E50 models sit at Beijing V, a tighter local standard. Neither is Euro VI, so check whether your market accepts Euro V-level homologation before committing — several import markets now require Euro VI for new registrations. Fuel quality matters too, since common-rail injection depends on clean, low-sulphur diesel.
No water tank capacity, no drum drive or hydraulic brand, no discharge rate, no residual rate, no slump range, no GVW separate from kerb and rated load, and no warranty or service terms. The mixing-performance figures in particular decide how many pours a truck can service in a shift, so ask for them before you compare prices.
