This SHACMAN 6x4 tractor truck is an F3000 model coded SX4255JT384, a 120-tonne super-heavy tractor that pairs the economical 380 HP WP10.380E22 Euro II engine with a Fast 12JSD200T-B 12-speed manual gearbox, 16-tonne double-reduction tandem axles at a 4.266 ratio and the same 15 mm three-layer frame used across this 120-tonne chassis family.

380 HP at a Full 120-Tonne Rating

Not every operator wants the largest engine on a super-heavy tractor truck, and this build is the answer to that. It carries the full 120-tonne-rated chassis — 850 x 300 (8+7), 15 mm three-layer frame, 9.5-tonne extra-heavy front axle and 16-tonne double-reduction tandem rear axles — but drives it with the proven 380 HP WP10.380E22 instead of a larger powerplant. For fleets where sustained gradeability at gross weight takes priority over outright horsepower, the smaller engine can mean lower fuel burn and a simpler service profile while still holding the same structural rating as its higher-output stablemate.

A 4.266 Ratio and Long Wheelbase for Stable Heavy Haulage

The 4.266 final drive on this SHACMAN 6x4 tractor truck is a short ratio chosen for tractive effort, letting the unit break a fully loaded lowboy away from rest on a grade instead of losing momentum. The 12JSD200T-B gearbox spreads the 380 HP over 12 forward and 2 reverse gears so the driver can hold the engine in its strong band at low road speed. A 7,450 mm body on a 3,775 plus 1,400 mm wheelbase gives a long, stable platform for oversized loads, and the 90 km/h governed top speed keeps a heavy combination settled on rough haul roads.

Mining Tyres, Cab and Options

This heavy tractor runs 12.00R20 mining wire tyres with a spare and a 90# reinforced saddle, matching the lowboy and dump semi-trailers used on mining contracts. The F3000 cab is offered as a flat-roof single-bunk unit or a high-roof double-bunk version, with an air-suspension seat and air cab mounting for long shifts. Buyers may also specify a 50# standard saddle in place of the 90# unit, an oil-bath desert air filter, ABS and fleet VI paint.
