Engineered for mountain haulage, emergency rescue and the refitting of Class II special-purpose vehicles, this Dongfeng single-row four-wheel-drive flat-head off-road chassis stands out as a robust and highly adaptable base solution for niche specialized vehicle customization.
Powered by a Cummins EQB150-20 engine mated to an 8-speed manual gearbox and a high-low range transfer case, the unit unlocks amplified torque in low-gear mode. It delivers remarkable traction to extricate itself from steep slopes and muddy terrain, perfectly matching power output to diverse heavy-duty off-road scenarios. Boasting a compact single-row flat-head cab, the chassis measures 6080×2290×2700mm with a 3700mm wheelbase, reserving a refitting length of no less than 4300mm to accommodate motorhome cabins, emergency response gear, engineering implements and a full spectrum of upper body assemblies.
Its frame is built with an 800×190mm thickened main beam featuring an 8+6 laminated structure, granting exceptional anti-torsion rigidity and load-bearing capability. Equipped with leaf-spring suspension, a 4.5-ton front drive axle and an 8-ton rear drive axle forming a full-time 4WD system, alongside six 8.25R16LT tires plus a spare wheel, it maintains steady load performance and reliable road adhesion across rugged, unpaved routes. With a total gross vehicle weight of 12,500kg and a chassis curb weight of merely 3,950kg, it retains abundant legitimate payload allowance.
Fine-tuned exclusively for off-road expeditions, it features a 37° approach angle, 30° departure angle, 300mm minimum ground clearance, 530mm obstacle-surmounting height and 630mm maximum wading depth, efficiently avoiding underbody scratches when traversing uneven wilderness and flooded sections. A 180-liter large fuel tank ensures extended cruising range, while the capped top speed of 85km/h strikes an optimal balance between driving safety and the service life of transmission assemblies.
Adopting an integrated factory 4WD architecture, it avoids potential faults and extra expenses brought by post-purchase secondary modification. Suited for customized vehicles such as forest fire fighting carriers, field engineering trucks, emergency wreckers and off-road campers, it accepts tailored chassis adjustments as required, cementing its position as a trustworthy premium option for small-scale special vehicle refitting projects.
