A tipper sold into the Gulf is not judged at a launch, it is judged at a weighbridge in fifty-degree heat with a body full of aggregate and a supervisor waiting. The BJ3259DLPKB-1 is that kind of machine, an Auman GTL 6x4 dump truck built for Saudi Arabia on the H1 heavy-truck business line, left-hand drive with a flat-roof cab for two, riding a 3825 plus 1350 mm wheelbase under an 8545 by 2550 by 3500 mm chassis. The tipping body measures 5600 by 2300 by 1500 mm inside, roughly 19.3 cubic metres, on a 2490 mm body width. At the front sits an 11800 ml engine and at the rear a 16 tonne drive axle geared at 4.76, driven through a twelve-speed Shaanxi Fast case, stopped by air drums with ABS, steered by a ZF8098 box, carrying 350 litres of diesel in aluminium, wearing eleven 12.00R20 radials. Every one of those choices points at the same job, moving earth and aggregate on short, heavy, repetitive cycles in a hot climate.
The engine is the Foton Cummins ISGe3-400, built by Beijing Foton Cummins, an 11800 ml in-line six recorded at 400 in the power column of this specification and 2000 N·m at 1000 r/min, calibrated to Euro III. The torque figure is the one that matters. Two thousand newton-meters arriving at a thousand revolutions means the truck moves off a loaded ramp in a middle gear with the engine loafing, which is how a heavy tipper keeps its clutch and its driveline mounts. Euro III here means a deliberately simple exhaust path, and the record lists no emission route, no aftertreatment model and no dosing system, so there is no urea to source at remote sites, no dosing module to clog, no catalyst exposed to the sulphur content that desert fuel stocks can carry, and no derate throwing a fault light mid-cycle. The trade is regulatory rather than mechanical, and it is addressed below. The power figure is recorded in a column headed kW/PS without a unit applied, so confirm it against the engine plate before publishing it to your own buyers.
Above the engine sits a Shaanxi Fast 12JSD180TA in iron-casing form, a twelve-speed manual whose 180 designation places it in the torque-capability class matched to this engine rather than to a lighter road unit. Twelve speeds on a tipper are not complexity for its own sake, they are how one truck covers two contradictory worlds. The crawler range gets a laden vehicle moving from a standstill on an unconsolidated ramp at a quarry face, and the top of the box keeps engine speed civilised on the sealed run back to site, while the steps in between mean fewer gearless moments where a tipper actually stalls a working day. Fast cases are iron-housed and cheap to rebuild, and in a market where every workshop understands the brand, parts availability is the real specification. The record carries an option code for a variant case, so confirm the exact configuration on the order sheet along with the axle groups listed as options.
Mass rating is where this record demands a hard conversation, because two of its own numbers disagree. The GVW field reads 55000 kg for a 6x4 whose axles are rated 7.5 tonnes front and 16 tonnes at the drive group, a published axle sum of 23.5 tonnes, and the GCW field is empty. On a rigid three-axle machine the axle ratings govern what can legally be carried, because that load must pass through those housings, springs and tyres to reach the ground, and a 55-tonne gross figure on 23.5 tonnes of axle capacity cannot both be true for registration anywhere. The realistic reading is that the tonnage class names the platform family rather than this vehicle's certified weight. Obtain the certificate mass, the permitted axle loads and the payload for the exact approved variant before loading to anything, and treat the 55T as a series label. Overload shows first at the spring seats and the drive-tyre shoulders, the most expensive place on a tipper to learn the lesson. For a fleet buying a heavy duty tipper truck into the Gulf, the certificate number, not the header, is the business case.
Under the body the structure is honest heavy work. The frame section is recorded as 225/320 by 90 mm with plate gauges of 8 plus 7, a varying-depth ladder rail with doubled side-rail material at the high-stress station, which is what carries the concentrated loads a tipping body puts into the chassis at the hinge and the ram rather than spread evenly along the rails. Suspension is leaf springs with ten leaves forward and twelve at the rear, and the steering is a ZF8098 recirculating-ball box, the reference standard on trucks of this class, keeping a laden front end positive on washboard haul roads where a lighter box would wander. As a quarry haulage truck on short cycles this combination matters more than any power figure, because a tipper's life is measured in ramp starts, kerb strikes and body rams rather than in highway kilometres, and every one of those loads goes straight into the frame depth, the spring count and the steering mounts.
Rolling stock and tank round out the duty picture. Tyres are Z8-pattern 12.00R20 radials, eleven of them, ten on the truck across a 6x4 layout with a dualed drive end and one spare, and a spare matters for a machine that cannot afford a roadside wait on a haul road. The 12.00R20 size on a 20-inch rim is the traditional heavy fitment in the Gulf market, deep-carcass, retreadable and stocked in every tyre shop from Dammam to Jeddah, which decides downtime more reliably than any warranty brochure. The fuel tank is 350 litres of aluminium, sized for site work close to depots rather than trunk distances. Braking is full air with drums front and rear and an ABS control system, the work-standard combination for dirty, dusty tipping duty where drums shrug off grit that would punish a disc, and the heat penalty of that choice is treated below.
The cab and body equipment tell you this is a site machine dressed sensibly rather than lavishly. Standard fitment is electric windows, central locking with the five-lock unification circuit, an air-sprung driver's seat as standard equipment, and manual rearview mirror adjustment, with manual air conditioning listed as standard, which in Saudi Arabia is not comfort but a tool for keeping the crew alert through a long shift. Entertainment is MP3 with radio and USB and, stated plainly, no reversing radar on this specification, an omission worth correcting locally on a truck that spends its day reversing into a waiting excavator. The tipping body is recorded at the 5600 by 2300 by 1500 mm internal figure with 2490 mm external width and an option field for the superstructure, while the deflector and saddle fields read as not fitted. This is the profile of a construction site truck, built for cycle speed and survivability under the body, not for long sealed hauls where a deflector earns its money.
Three businesses fit this configuration and one common assumption does not. The core case is the quarry-to-plant cycle, the quarry haulage truck duty of aggregate, base course and blasted rock moving short distances over ground that punishes everything except deep frames, twelve rear leaves and a ZF box on a wide torque plateau. The second is the construction site truck case, excavation and municipal work inside cities, spoil removal, trench backfill and demolition haulage, where the 19.3 cubic metre body suits dense material, the 6x4 footprint turns in tight sites, and the air-sprung seat keeps a two-man crew productive. The third is port, yard and industrial estate tipping, where the sealed running is short and the cycles are many. What does not fit is line-haul at gross on the highway assumption the 55-tonne header implies, because 350 litres of fuel, 4.76 gearing and drum brakes with no listed retarder describe a point-to-point site machine, and a fleet buying it as a long-haul rig will be disappointed in exactly the ways that cost money.
Ownership economics on this truck are dominated by three consumables. Tyres are the first cost on any tipper, and here the choice is genuinely wise, since 12.00R20 casings are the most retreadable and most widely stocked heavy size in the region, keeping per-cycle cost low even after the first life. Fuel and aftertreatment are the second, and a Euro III engine with no dosing system, no NOx sensor ladder and no catalyst to steal removes the failure categories that dominate the workshop diaries of modern emission-compliant tippers, at the price of the registration risk stated below. Brakes are the third, and this is where the record asks for discipline, because the brake list carries drums and ABS with no auxiliary braking system recorded, no exhaust brake, no retarder and no engine brake, so on any sustained loaded descent the kinetic energy must be absorbed by the driveline in a low gear rather than by the linings, and a fleet working hills or ramped tips must train that behaviour and budget shorter lining intervals. Buy this as a heavy duty tipper truck on short flat cycles and the numbers work; buy it for mountain carting without addressing the retarder question and they do not.
State plainly what this record does not contain. No payload, kerb weight, body material, hoist model, gradeability, turning circle, maximum speed, fuel consumption or ground clearance is published and none is claimed here, and the 55000 kg GVW against a 23.5 tonne axle sum must be reconciled against the certificate for the exact approved variant before any load plan is built on the header figure. No auxiliary brake, reversing radar, stabiliser-bar commitment or sleeper is listed, the emission route field is empty on a Euro III machine, and the power figure sits in a column headed in two units without one selected, so confirm it from the nameplate. No warranty, service network or after-sales commitment appears in the record and none is implied, and the Euro III level must be checked against current Saudi registration and import requirements for the ownership period you intend. The coverage list on this project spans Panama, French Polynesia, Kyrgyzstan, Guinea, Saudi Arabia, Uruguay and Jamaica, which tells you the platform is built to absorb whatever local fuel and roads throw at it. Send your cycle profile, material density, altitude and certified masses, and this 6x4 dump truck can be confirmed against the numbers that decide whether it earns, rather than against a brochure.
