How many cubic metres does the tipping body hold?

The sheet publishes two internal lengths over the same width and height, 5400/5600×2300×1500 mm. Struck to the rail with no heap: 19.32 m³ at 5,600 mm and 18.63 m³ at 5,400 mm. Both are plain multiplication of the published dimensions.

What is the rated payload?

Not published. Maximum design gross mass 25,000 kg less chassis kerb weight 10,460 kg leaves 14,540 kg, and the body, hoist, hydraulics, a full 350L aluminum alloy tank and two occupants all come out of it before the load does. Get the body tare from the body builder and subtract.

At what material density does the box stop being the limit?

About 0.75 t/m³. Below that the loader fills the box while the axles still have capacity; above it the truck reaches 25,000 kg with the corners of the box still empty. The density of your own material is the one figure this sheet cannot supply.

Will I overload it if the loader fills the box with ore?

On paper, yes. At 2.6 t/m³ a full 19.3 m³ box works out to roughly 50 tonnes, against a 25,000 kg maximum design gross mass. In practice the operator stops short, which is exactly the point: on dense material the box is not the constraint.

What is the maximum gradeability?

32 (5.26) per cent at the 5.26 ratio this truck carries. The same row also publishes 37 per cent at 5.92 and 29 per cent at 4.76.

What holds it back on a loaded descent?

An exhaust brake, and that is the only retarding device on the sheet. Service brakes are dual-circuit air brake, front and rear drum; no engine brake row and no hydraulic retarder row appear. On a long descent that puts the service brakes in charge.

Is the 1,500 mm side wasted on hard rock?

Largely, yes. Once the material is dense enough that mass governs, the extra height is steel carried up every ramp, every shift. On dry topsoil, overburden, coal or light aggregate it is the opposite: every extra cubic metre is a round trip you did not have to repeat.

How big is the fuel tank?

350L aluminum alloy aluminium alloy. The sheet publishes no consumption figure, so no range is quoted here.

Does it come with a speed limiter?

No. The speed limit value row reads None and the overspeed alarm value row reads None. Most mine safety regimes want a governed maximum fitted and calibrated locally.

Mining Haulage on the GTL 6×4 375: What Each Row Does Across One Loaded Cycle

Writer:Alan Chen(Foton Auman dealer)

Most specification sheets say what a truck is. This one goes further and says where it expects to work: the operating-condition field reads Mining operation heavy-duty type, and the classification row beneath it says N3. Everything below takes that line seriously and asks what each published row actually does through one loaded cycle on a pit road.

Start at the two masses, not the engine

The engine is where every brochure starts and it is almost never what decides the cycle. What decides the cycle is how much of the truck's permitted mass is left over once the truck itself is weighed, and this sheet is unusually candid about it: maximum design gross mass 25,000 kg, chassis kerb weight 10,460 kg. The difference is 14,540 kg, and four separate things come out of it.

Comes out of the 14,540 kg	What the sheet says about it
The tipping body and hoist	Nothing. No body weight is published on this sheet, on any of the three variant dimensions.
Fuel at full tank	Tank capacity is published as 350L aluminum alloy; the sheet does not convert it to mass.
Two occupants	Occupants is published as 2.
Whatever is in the box	Everything above has to be paid for first. The remainder is the payload, and it is not published.

So the one number a mining operation actually runs its cost model on — tonnes per trip — is the one number this sheet does not carry. It can be derived once the body builder quotes, and it cannot be derived before. Ask for it first.

A box that most rock will never fill

Two internal box lengths are published, 5400/5600×2300×1500 mm. Taken struck, to the top rail with no heap, those are 19.32 m³ and 18.63 m³. Now put a density against them and see what happens to the scale. The arithmetic is multiplication and nothing else; no assumption about your dig is baked into it.

Loose bulk density of the material	Full 19.32 m³ box weighs	Full 18.63 m³ box weighs	Against the remaining 14,540 kg
0.9 t/m³	17.4 t	16.8 t	Fits inside a 25,000 kg truck: no — well over it
1.2 t/m³	23.2 t	22.4 t	Fits inside a 25,000 kg truck: no — well over it
1.5 t/m³	29.0 t	27.9 t	Fits inside a 25,000 kg truck: no — well over it
1.8 t/m³	34.8 t	33.5 t	Fits inside a 25,000 kg truck: no — well over it
2.2 t/m³	42.5 t	41.0 t	Fits inside a 25,000 kg truck: no — well over it
2.6 t/m³	50.2 t	48.4 t	Fits inside a 25,000 kg truck: no — well over it

Read across that table and the practical picture changes shape. Once material density climbs past roughly half a tonne to the cubic metre, the box is no longer the constraint — the axle ratings are. A truck digging iron ore, copper ore, wet gravel or blasted hard rock will reach 25,000 kg long before the loader operator has filled the corners, and the difference between a 5,600 mm box and a shorter one is then dead weight carried up every ramp, every shift, forever.

Where the deep box earns its keep is low-density material: dry topsoil, overburden, coal, arisings, light aggregate. There, every extra cubic metre is a round trip avoided. Where it does nothing is ore — and if your pit is ore, the question worth asking the body builder is whether a shorter, lighter body increases tonnes per trip by giving mass back to payload.

Foton Auman GTL 6x4 dump truck tipping body — Published internal: 5400/5600×2300×1500 mm, a choice of 5,400 or 5,600 over the same 2,300 width and 1,500 height.

Foton Auman GTL 6x4 dump truck body and hoist area — No body weight is published on this sheet, so tonnes per trip has to come from the body builder.

One loaded cycle, six rows that answer it

What the cycle demands	The row that answers it	And the limit written next to it
Pulling away loaded on a loose ramp	Peak torque 1650/1100-1500 N·m across that whole band, from a 10338 ml inline six with no electronic injection to protect	Mechanical pump fuel delivery. Simple, field-serviceable, and a choice that also sets emission at Euro II.
Climbing out loaded	Drive axle ratio 5.26 behind a 16-tonne rear bogie with a 9-tonne front axle, cast housings	Maximum gradeability published at 32 (5.26)/37 (5.92)/29 (4.76) per cent depending on ratio — 32 % at the 5.26 this truck carries.
Holding it back on the way down	Exhaust brake listed as the auxiliary brake	It is the only retarding device on the sheet. No engine brake row, no hydraulic retarder row. Service brakes are dual-circuit air on drums front and rear.
Surviving the ramp surface	Rear suspension described as Disconnected balance suspension, 11/14 leaf springs, front as Longitudinal leaf spring with stabilizer bar and shock absorbers	Frame published at 225/320×90×(8+7) mm, outer width 915 mm front / 850 mm rear and axle housings cast. This is the part of the sheet that reads like it was written by someone who has seen a washboard haul road.
Breathing dust for a full shift	Air filter type reads Desert, muffler Longitudinal square	Fuel tank 350L aluminum alloy for range between refuels. Neither a filter service interval nor a consumption figure is published.
Keeping it running at the pit	Cab on Semi-floating spring suspension with manual tilt; fuel system a mechanical pump	Maximum speed published at 67 (5.26)/60 (5.92)/74 (4.76) km/h by ratio — 67 km/h at 5.26 — and the row for a speed limit value reads None.

The strong rows are the ones nobody quotes in an advert: the rear suspension being described as disconnected balance, 25 leaves counted across the two axles, cast axle housings, and a frame with its section and both outer widths written out. Those four lines describe a chassis built to articulate over ground that is not flat, which is what a haul road is.

What the pit will make you add afterwards

This is the list worth pricing before signing, because every item on it is absent rather than optional:

Governing. Speed limit value reads None and overspeed alarm value reads None. Most mine safety regimes want a governed maximum, fitted and calibrated locally.

Reversing awareness. Entertainment reads MP3 + radio + USB + no radar, and the trim line specifies manual rearview mirrors. Nothing here detects anything behind the truck, which matters more at a loading face than on a road.

Access. Working platform reads None and side skirt reads None. If crews sheet a load, check it or climb the body, a platform has to be fabricated.

Visibility and trim. No wheel cover, no AC power converter, and the rearview mirrors are manual on a trim that otherwise includes electric windows, central locking, five locks unified and an airbag seat as standard.

Fire and safety equipment. Nothing on this sheet rows it in. Whatever the site rulebook requires arrives as a local line item.

None of this is a criticism of the truck. It is what a sheet written wholesale for export looks like: the chassis is specified to a high standard for rough ground, and the site-specific fittings are deliberately left to the destination. The cost of discovering that after arrival is what makes it worth reading now.

Where this configuration stops being the answer

Two situations take it off the shortlist, and the sheet itself supplies both reasons. If the haul leg is long and mostly sealed — pit gate to port, or over a hundred kilometres of tar — the 5.26 that makes it good on a ramp costs road speed it will not get back, and the 4.76 alternative in the same catalogue is the better shape. If the work answers to an emissions certificate rather than to a scale house, the Euro II row ends the conversation and the Euro V entry takes it. Mining duty does not automatically mean this truck; it means this set of rows, and those two sit on different sheets.

Recorded from the truck's own published listing: masses, box dimensions, torque band, injection type, axle loads and ratio, suspension description, frame section, braking rows, air filter and tank, cab equipment, and the rows left empty. Box volumes are computed from the published internal dimensions, struck with no heaping allowance. The density table applies plain multiplication to those volumes and states no material property as fact — the density of your own dig is yours to establish. No cycle time, fuel consumption, payload, gradient typical of any named mine, or national requirement is asserted here, because this sheet publishes none of them.
