It’s not a tanker you’d use for liquids—this one is strictly for dry bulk powders like cement, lime, or mineral dust, and the 38m³ geometric volume matches the effective capacity, so no hidden space issues. The 4mm Q235 carbon steel walls are about standard for this class, but the sand blasting and three-layer paint job means it holds up better than cheaper bare-metal options in coastal or dusty yards.

45 tons of payload is the max, but you’ll usually hit that with cement density around 1.2 tons per cubic meter—lighter materials like lime might leave some headroom. What really matters is the pneumatic unloading system: it pushes matrial out at over 1.2 tons per minute using a 12m³ Wuhu or Bohai air compressor driven by a Weichai Kefa 4102 diesel engine (which is pretty much the standard power unit in this segment).

The 3×13-ton FUWA axles with air suspension give a smoother ride than leaf springs, and the ABS plus T30/30 spring brakes mean it stops predictably even when fully loaded—better than relying on manual brake adjustments on older trailers. Most buyers we see go with the 2-inch kingpin for standard tractors, but the 3.5-inch bolt type is available if you’ve got a heavier-duty fifth wheel.

Lead time is usually 20 days or so from order, but we’ve had some batches take up to 35 days depending on whether we’re between —confirm before you pay. The ISO9001 and CCC certs are there, but honestly, teh real reliability check is the 28-ton landing gear capacity; it’s one of those details you don’t think about until you’re parked on uneven ground and the trailer doesn’t sag.

Anyway, for ordering: we need the kingpin size and whether you want standard 12m³ compressor or a higher-output unit (though 12m³ is enough for most 38m³ tanks). Shippng goes via container or flat rack, and we usually have stock, but confirm lead time if you’re in a rush—the 45-ton payload version tends to move faster than the lighter-duty builds.
Both — the geometric and effective capacities are 38m³, so you can load that full volume without any derating for bulking or aeration.
We stock both kingpin sizes, so switching to 3.5" won't add more than 3–5 working days to the standard 30-day lead time.
Yes, we include both certificates in the documentation package — they're standard with every trailer we ship.
We can do stainless steel on request, but it'll change the price and lead time — the standard build is 4mm Q235, which handles cement and lime fine.
We require a minimum of 1 unit for a first order, but we offer volume discounts starting at 5 units.
