This SHACMAN H3000 4x2 tractor truck is the 400 HP build of the SX4185 4x2 family. It pairs a 12-litre Weichai WP12.400E201 Euro II engine with a FAST 12JSD200T-B 12-speed manual gearbox, a 4.266 rear axle ratio, a 16-tonne double-reduction drive axle and a strengthened 850 x 270 (8+5) frame rated to 50 tonnes gross combination weight. It is a single-drive tractor for trunk haulage in Africa, the Middle East and Latin America, where Euro II fuel quality and simple mechanicals matter more than electronics.

Twelve Litres and 400 HP on a 4x2 Chassis

The 400 HP rating in this SHACMAN H3000 4x2 tractor truck comes from the WP12, an 11.6-litre six-cylinder engine, rather than the 9.7-litre WP10 fitted to the 380 HP version of the same chassis. That extra displacement is where the torque reserve lives: a 12-litre engine holds pulling power at lower rpm, so a loaded trailer on a long climb does not force the driver to drop two gears and lose momentum. For operators running hilly trunk routes, or hauling near the top of the 50-tonne combination limit, the H3000 4x2 tractor truck at 400 HP is the version that stops feeling short of breath.

The 4.266 final drive sits between a tall shuttle ratio and a deep heavy-haul ratio, which is a sensible compromise for an H3000 4x2 tractor truck on a fixed regional route. It keeps cruising rpm low enough for fuel economy while still giving the 12-litre engine enough multiplication to restart a loaded combination on a grade.

Why a 16-Tonne Double-Reduction Axle Matters Here

A single-drive tractor puts the whole trailer load through one rear axle, so the axle is the part that decides how long the truck lasts. This SHACMAN H3000 4x2 tractor truck uses a 16-tonne double-reduction drive axle behind a 7.5-tonne front axle, with multi-leaf springs at both ends and the strengthened 850 x 270 (8+5) double-layer frame. Double reduction splits torque across two gear stages, so individual gear teeth carry less stress than in a single-reduction axle of the same rating, and the difference shows up in final-drive life on a truck that runs loaded most of the time.

Kerb weight is 7,100 kg, which leaves a useful payload margin inside the 50-tonne gross combination rating. A 50# reinforced fifth wheel is standard and couples to a standard flatbed, container or tanker semi-trailer.

Cab, Fuel Range and What You Can Change

The H3000 cab is air-suspended with an air-suspension primary seat, electric windows and a steel bumper. It ships flat-roof with a single bunk at 3,300 mm overall height, or high-roof with a double bunk at 3,800 mm. A 400 L aluminium fuel tank and twin 165 Ah maintenance-free batteries give a working range between stops without adding steel weight, and 12R22.5 vacuum tyres with one matching spare are standard.

Specification is not locked at order. Buyers can take a 90# reinforced fifth wheel, ABS, an oil-bath desert air filter for dusty markets, or a custom fleet paint scheme. Tell us your route, the trailer you pull and your destination port, and we will confirm the build sheet, condition and an FOB or CIF price for your H3000 4x2 tractor truck before you commit.

Frequently Asked Questions

What engine is in this 400 HP SHACMAN H3000 4x2 tractor truck?

It runs the Weichai WP12.400E201, an 11.6-litre six-cylinder Euro II engine rated at 400 HP, mated to the FAST 12JSD200T-B manual gearbox with 12 forward and 2 reverse gears.

How does the 400 HP version differ from the 380 HP H3000 4x2?

The 380 HP build uses the 9.7-litre WP10.380E22. This H3000 4x2 tractor truck uses the larger 11.6-litre WP12 at 400 HP, so it holds speed better on climbs and under near-maximum combination weight, at the cost of slightly higher fuel burn when running light.

What can this H3000 4x2 tractor truck pull?

It is rated to a 50-tonne gross combination weight with a 50# reinforced fifth wheel, which covers standard flatbed, container and tanker semi-trailers. Confirm the figure against your local axle-load regulation before you commit to a trailer.

Is the 4.266 rear axle ratio right for my route?

The 4.266 ratio in this H3000 4x2 tractor truck suits a regional trunk route with mixed gradients. If you run flat motorway work at light load, a taller ratio returns better fuel figures; if you pull maximum weight on steep ground, a deeper ratio is worth asking about.

Can I specify a high-roof cab, ABS or a 90# fifth wheel?

Yes. Flat-roof single bunk or high-roof double bunk, a 90# reinforced fifth wheel, ABS, an oil-bath desert air filter and custom fleet paint are all selectable at order.
