Key Benefits

What This Unit Does Well

  • 385HP engine delivers strong pulling power for loaded gradients and heavy trailers
  • Fuller 12JS160T 12-speed gearbox offers fine gear ratios for both loaded and empty runs
  • German MAN front axle and STR 13T rear axle provide high load capacity and durability
  • EURO 4 emission standard avoids AdBlue dependency in markets without urea infrastructure
  • 12.00-20 tyres are widely available and compatible with standard rims in export markets
  • LHD and RHD versions available to match local driving regulations and registration needs
Application Scenarios

Where It Is Used

  • Long-haul coal transport on unpaved roads with frequent axle loading and high torque demands
  • Oil and gas field transport where heavy trailers must be pulled over rough terrain
  • Engineering fleet operations requiring a robust tractor head with high axle load and reliable transmission
  • Container transport on mixed asphalt and gravel routes where axle strength is critical
Fit

Who It Is For

  • Fleet owners replacing older prime movers with higher torque and axle capacity
  • Contractors operating in mining or oil and gas zones where axle load and engine power are key
  • Machinery dealers stocking heavy-duty tractor heads for resale in high-load markets
  • Government procurement teams sourcing vehicles for infrastructure or military transport
Buyer Pain

Problems It Solves

  • Tractor heads with insufficient axle load capacity that fail under heavy trailer loads
  • Transmission systems that lack enough gears for efficient operation on steep gradients
  • EURO 5 engines requiring AdBlue that are not feasible in remote or low-infrastructure regions
  • Lack of local spare parts for front and rear axles due to non-standard or imported brands
Engineering

Process

How an Order Is Handled

  • You send the route profile, payload and trailer type you will pull
  • We match a chassis code and axle ratio against what is available in stock or from the plant
  • You confirm the final specification sheet including colour, cab and tyre before deposit
  • Unit is prepared, photographed and video recorded before loading
  • We book RoRo or container shipment and issue the export documents your customs needs
Quality Control

Checks Before Loading

  • Chassis, engine and gearbox numbers are photographed and matched to the specification sheet you approved
  • Engine start, gear engagement and air system are recorded on video before loading
  • Paint, glass and cab trim are checked for transport damage at the loading port
  • Loading and lashing photos are sent before the vessel departs
Customisation

What Can Be Changed

  • Cab colour other than the default white
  • Sleeper layout, single or double bunk
  • Left hand or right hand drive as your registration requires
  • Tyre brand and spare wheel count
  • Additional fuel tank, tool box or fifth wheel height change
Honest Comparison

How It Compares With the Alternatives

4x2 tractor headThe 6x4 carries more weight on the drive axles, reducing wear and improving traction on loaded gradients, but uses more fuel when running empty
EURO 5 emission tractor unitsEURO 4 avoids AdBlue supply and sensor faults in markets without reliable urea, but cannot be registered where EURO 5 is mandatory
Use Guide

Using It Well

  • Replace fuel and oil filters on the interval set for 385HP engines, not on a generic schedule
  • Keep the air dryer cartridge stocked, humid coastal routes shorten its life
  • Order the clutch plate and injector set with the truck so the first service does not wait on shipping
