Product Description
This SHACMAN 4x2 tractor truck, model SX4185JU361, is the heavy-duty F3000 build set up for hard pulling and rough operating conditions. It pairs a 400 HP Weichai WP12.400E201 Euro II engine with a FAST 12JSD200T-B 12-speed manual gearbox, a deep 4.769 rear axle ratio, a 16-tonne wheel-hub double-reduction drive axle, a heavy (940-850)x300 (8) frame and a 50-tonne gross combination weight rating.
A Deep 4.769 Ratio and a 16-Tonne Wheel-Hub Axle
This version of the SX4185JU361 is tuned for tractive effort. The short 4.769 final drive multiplies engine torque at the wheels, and the 16-tonne wheel-hub double-reduction rear axle is built to survive continuous heavy loads and poor surfaces. Together they let a fully loaded tractor truck pull away on a ramp, a quarry approach or a broken access road without straining the driveline.
This SHACMAN build is the one to choose when the route includes gravel, debris or poor roads rather than smooth highway. The F3000 package backs that up with protection hardware: a 5 mm thickened steel front bumper with headlamp guards, a water-tank protection grille and front and rear lamp protection nets.
Steel Tank, 90# Fifth Wheel and Working Comfort
SHACMAN leans the specification toward durability. A 90# reinforced fifth wheel, a 380 L steel fuel tank and 315/80R22.5 vacuum tyres with a spare are standard, while the cab uses a hydraulic seat, hydraulic cab mountings, heating and cooling air conditioning, and electric windows. The result is a tractor truck that keeps a driver comfortable while standing up to daily punishment.
Buyers can still refine the build: cab height, a swapped 50# fifth wheel, a desert oil-bath air filter, an added or aluminium fuel tank and custom fleet paint. Because the destination market is not recorded for this unit, tell HiCA AUTO where it will operate and we will confirm the configuration, condition and price.
Frequently Asked Questions
How is this SX4185JU361 different from the 3.866 version?
Both are SX4185JU361 F3000 4x2 tractors. This one runs the deep 4.769 ratio with a 16-tonne wheel-hub rear axle and a 90# fifth wheel for maximum pulling, while the 3.866 version uses a tall ratio and a lighter 13-tonne axle.
What engine and gearbox does this SHACMAN tractor truck use?
It uses the Weichai WP12.400E201, a 400 HP Euro II engine, mated to the FAST 12JSD200T-B manual gearbox with 12 forward and 2 reverse gears.
Why choose such a short 4.769 final drive?
A short ratio trades top speed for tractive effort. It lets a loaded 4x2 tractor truck start and climb on ramps, quarry approaches and poor roads where a tall highway ratio would struggle.
What protection does the F3000 package add?
It adds a 5 mm thickened steel front bumper with headlamp guards, a water-tank protection grille and front and rear lamp protection nets, so the truck tolerates gravel and debris on rough routes.
