This SHACMAN 6x4 tractor truck is a brand-new H3000 model coded SX4255HT324, specified for 70-tonne engineering logistics and mining semi-trailer duty. A 380 HP WP10.380E22 Euro II engine feeds a Fast 10JSD180 10-speed manual gearbox and 16-tonne double-reduction tandem rear axles at a 4.769 ratio, giving strong low-speed pulling power for heavy combinations.

A 4.769 Ratio Built for Mining and Engineering Pulls

A 4.769 final drive is a deep, short ratio, and on this SHACMAN 6x4 tractor truck it is there for one reason: turning engine torque into wheel force at low speed. On a mine haul road or a graded site ramp, that lets a loaded semi-trailer get moving and keep climbing instead of stalling. The consequence is a governed top speed of 80 km/h, which is a deliberate trade — this build favours grip and durability over highway pace. The 10JSD180 gearbox with 10 forward and 2 reverse gears is matched to that character, keeping the 380 HP engine working in its strongest band under sustained heavy load.

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

This 6x4 tractor truck carries 16-tonne double-reduction tandem rear axles behind a 7.5-tonne front axle, mounted on a reinforced 850 x 300 (8+5) double-layer frame with multi-leaf springs sized for repeated full-load cycles rather than occasional peaks. Kerb weight is 8,500 kg against a gross combination weight of 70 tonnes. Twin fuel tanks of 400 L plus 230 L and a 165 Ah maintenance-free battery keep working range up between stops, while 13R22.5 reinforced vacuum tyres with a spare and a 90# reinforced saddle match the heavy semi-trailers used in mining and engineering fleets.

Cab, Gearbox Detail and Factory Options

The H3000 flat-roof cab gives an air-suspension seat, air cab mounting, electric windows and a steel bumper, so long shifts on rough access roads stay comfortable for the driver. Buyers are not fixed to 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 fleet paint scheme can each be specified at order. Share your trailer type and duty cycle and we will confirm the build sheet before quoting this SHACMAN heavy tractor truck.

Frequently Asked Questions

Why does this SHACMAN 6x4 tractor truck use a 4.769 ratio?

A 4.769 final drive is a deep ratio for low-speed tractive effort. It keeps a 70-tonne mining combination moving on gradients and haul roads rather than chasing top speed.

What gearbox does this SHACMAN tractor truck have?

It uses the Fast 10JSD180 manual gearbox with 10 forward and 2 reverse gears, matched to the 380 HP WP10.380E22 Euro II engine.

What load class is this 6x4 tractor truck built for?

The SX4255HT324 is rated to a gross combination weight of 70 tonnes, with 16-tonne double-reduction rear axles on a reinforced (8+5) frame.

Can this mining tractor truck be customised?

Yes. High-roof cab, 50# saddle, oil-bath desert air filter, ABS and fleet paint are available. Share your trailer type and we will confirm the build before quoting.
