Sinotruk HOWO NX 6×4 Tractor Truck, 68 m³ shipping volume

What this machine is

The Sinotruk HOWO NX 6×4 tractor unit in its high-power form. Three axles, the rear two driven, a Weichai or MAN-derived engine at 460 to 480 hp, a 12-speed manual gearbox and the HW79 single sleeper cab. Rated at 40 tonnes towing.

Overall 7.05 m long, 2.55 m wide and 3.80 m tall, on 12.00R20 tyres. Left-hand drive, convertible to right-hand drive. China II, III or V by unit. Listed as new stock, model years 2020 to 2021.

What it is used for

Haulage, on the routes that punish a truck.

Gradients. Escarpments, mountain passes and the long climbs inland from a coastal port. This is the single clearest reason to buy power you do not strictly need on the flat.

Heat and altitude. Both cost an engine output. A truck rated at 460 hp at sea level in temperate air is not delivering 460 in forty degrees at a thousand metres, and the margin is what keeps the combination moving.

Full weight, every day. A contract haul at 40 tonnes each way is a different duty cycle from a truck that runs loaded one way and empty back.

Why the power, and what it costs

The honest framing is that 371 hp will tow 40 tonnes. Every 6×4 tractor unit on this site is rated for the same weight. The question is not whether it can, it is what it costs the truck to do it.

An underpowered combination on a long climb runs in a low gear at high revs for extended periods. That is heat in the engine, heat in the gearbox, and a driver who takes the hill at whatever speed the truck will give. Over years, that is where the repair bill comes from. Where your route has real gradients, the extra power is not comfort, it is the difference in how long the driveline lasts.

Two things it costs you. Fuel, on the flat, where the bigger engine is working below its efficient range and the smaller one is not. And freight: 68 m³ against 55 for the standard NX, because the HW79 cab is 3.80 m tall against 3.10.

If your work is flat corridor running, buy the 371 hp NX, save 13 m³ of freight and spend the difference on diesel over ten years and come out ahead. If your route climbs, do not.

Condition, and what we do before it ships

Through our own workshop before it loads: inspected, put right, and photographed at each stage.

This unit is listed as new stock, so ask for the two documents that matter on a claim like that: the plate and the odometer, photographed. On the engine, ask us to confirm from the plate whether the specific truck carries the Weichai or the MAN-derived unit, because the listing covers both and you should know which one you are buying.

Shipping it

68 m³. The tall HW79 cab is what you are paying for on the vessel, and the same figure applies to the HOWO TX and the two big Shacman cabs. Loaded at our yard in Tangshan, shipped through Tianjin Port.

What to tell us

Your route, and specifically its gradients. Whether the truck runs loaded both ways. What you will pull. Your destination port, the quantity and whether you need right-hand drive.
