Product Description
The SX4185JU361 is a SHACMAN 4x2 tractor truck configured for fast port and shuttle work rather than maximum pulling. It pairs a 400 HP Weichai WP12.400E201 Euro II engine with a FAST 12JSD200T-B 12-speed manual gearbox, a tall 3.866 rear axle ratio, a lighter 13-tonne wheel-hub double-reduction drive axle, a variable-section (940-850)x300 (8) frame and a 50-tonne gross combination weight rating.
A Tall 3.866 Ratio for Fast Turnaround
Where the heavy-duty version of the SX4185JU361 uses a deep 4.769 final drive, this build runs a tall 3.866 ratio. That raises road speed at a given engine speed, so this SHACMAN tractor truck moves quickly between a port gate and a nearby yard or between shuttle stops. It is the right choice where the load is light and the priority is trips per day rather than pulling power.
The running gear is matched to that lighter duty: a 13-tonne wheel-hub double-reduction rear axle and front three / rear four few-leaf springs cut unsprung weight, while a 7.5-tonne front axle carries the front end. Fewer leaves also soften the ride when the truck runs empty.
Aluminium Tank, 50# Fifth Wheel and an Upgrade Path
This SHACMAN 4x2 tractor truck is finished for efficient high-frequency operation. A 400 L aluminium fuel tank saves weight over steel, a 50# diamond fifth wheel matches standard port trailers, and 12R22.5 vacuum tyres with one matching spare are standard. The cab is flat-roof or high-roof with a single bunk, an air-suspended primary seat and four-point air suspension.
Unusually, this model can also be upgraded from 4x2 to 6x4 before delivery, so one order covers both a shuttle tractor and a heavier trunk unit. Cab height, a 50# or 90# fifth wheel, an oil-bath desert air filter, a 400 L or 600 L aluminium tank and custom paint can all be specified. Tell HiCA AUTO how you will run it and we will confirm the configuration, condition and price.
Frequently Asked Questions
How does this SX4185JU361 differ from the 4.769 version?
They are the same F3000 model. This build runs a tall 3.866 ratio, a lighter 13-tonne rear axle and few-leaf springs for fast port and shuttle work, while the other uses a deep 4.769 ratio and a 16-tonne axle for heavy pulling.
What engine does this SHACMAN 4x2 tractor truck use?
It runs 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 use few-leaf springs instead of a multi-leaf setup?
Few-leaf springs (front 3 / rear 4) cut weight and give a softer ride when the truck runs light, which suits a tractor truck on short, high-frequency runs rather than constant maximum load.
Can this truck be supplied as a 6x4?
Yes. This model supports a 4x2 to 6x4 upgrade before delivery, so it can serve as a shuttle tractor or be built heavier for trunk work. Ask us for the exact configuration.
