This SHACMAN 6x4 tractor truck is a brand-new H3000 model coded SX4255HV324, configured for 70-tonne engineering logistics, heavy haulage and mining semi-trailers. It combines a 430 HP WP12.430E201 Euro II engine with a Fast 12JSD200T-B 12-speed manual gearbox, 16-tonne double-reduction tandem rear axles at a 4.266 ratio and a reinforced 90# fifth wheel.

A 430 HP Engine and a 4.266 Ratio for Heavy Pulling

The WP12.430E201 at 430 HP gives this SHACMAN 6x4 tractor truck the torque headroom that 70-tonne combinations demand. The 4.266 final drive is a short ratio chosen for tractive effort rather than road speed, so the vehicle can pull a loaded lowboy or tipper semi-trailer from a standstill on a gradient or a soft site floor instead of bogging down. The 12JSD200T-B gearbox splits that power across 12 forward and 2 reverse gears, letting the driver hold the engine in its efficient band whether crawling through a mine gate or running between sites. Top speed settles at 90 km/h, a sensible ceiling for a truck that spends its life heavy.

16-Tonne Double-Reduction Axles and a 70-Tonne Rating

Rear axle sizing is where a heavy tractor earns its rating, and this one runs 16-tonne double-reduction tandem axles behind a 7.5-tonne front axle, carried on a reinforced 850 x 300 (8+5) double-layer frame with multi-leaf springs rated for continuous load cycles. Kerb weight is 8,500 kg against a gross combination weight of 70 tonnes. Two fuel tanks at 400 L plus 230 L and a 165 Ah maintenance-free battery extend working range between stops, while 13R22.5 reinforced vacuum tyres with a spare and a 90# reinforced saddle keep this 6x4 tractor truck matched to the heavy semi-trailers used in mining and engineering fleets.

Cab Comfort and Factory Options

The H3000 cab on this 6x4 tractor truck is a flat-roof design with an air-suspension seat, air cab mounting, electric windows and a steel bumper, so a driver can stay productive through long shifts on rough access roads. Buyers are not locked into that layout: a high-roof double-bunk cab, a 50# saddle in place of the 90# unit, an oil-bath desert air filter for dusty sites, ABS and a custom fleet paint scheme can each be specified at order. Share the trailer type and duty cycle and we will confirm the build sheet before quoting this SHACMAN heavy haul unit.
