A 9,450 mm bucket on a 60,000 kg truck is a statement about material density, and it is the first thing to test before you look at anything else. This Auman EST 8×4 pairs the largest body in its range with a Cummins ISG 380 — 380 PS and 2,000 N·m between 1,000 and 1,300 rpm — driving a Fast Gear 12-speed to 5.26 axles, in a right-hand drive flat-roof cab. It is aimed at quarry transport, earthmoving and aggregate delivery. Three questions decide whether it is right for you: when a 9,450 mm body actually pays, whether 380 PS is enough at 60 tonnes, and how an 11.5-metre truck ships. Read the Auman EST 8x4 dumper specification alongside this.

When does a 9,450 mm bucket pay off?

The 9,450×2,300×1,500 mm body is the largest in this range and is aimed at light, voluminous material — coal, aggregate, overburden — where you run out of volume before you reach the 60,000 kg GCW. That is the condition under which this truck makes money: every cubic metre is earning, and the extra length converts directly into trips you do not have to make.

With dense ore the arithmetic reverses. You will hit the GCW and the 9 T front and 16 T rear axle limits with the body barely half full, and from that point you are carrying dead weight and dead length for nothing — paying for steel, tyres and a longer turning circle that produce no revenue. If your material is heavy, the shorter 7,600 mm body on the same driveline is the more productive combination. Work out your material density per cubic metre before you choose; it is the single input that decides this.

"The 9,450 mm body pays only if volume fills the truck before weight does. With dense ore you are hauling steel, not product."

Is 380 hp with a 12-speed enough at 60 t?

The Cummins ISG 380 makes 279 kW / 380 PS at 1,900 rpm and 2,000 N·m between 1,000 and 1,300 rpm, driving through a Fast Gear 12JSD180TA Iron (Q) gearbox to 5.26 axles. That is a well-matched combination for 60,000 kg GCW. The wide torque plateau is what lets you hold a gear on a loaded climb, and the 12-speed keeps the steps small enough to stay inside it — the two things together matter more here than the peak power figure.

Fast Gear is the other notable change from the Sinotruk units used elsewhere in this range. It is a widely distributed Chinese heavy-truck gearbox brand with good parts coverage, and the 12JSD180TA is a familiar designation for workshops that service this class. Ask the dealer to confirm the ratio spread and the top-gear ratio, because with a 5.26 final drive those determine your cruising speed on transfers. If your haul road has long sustained gradients, higher-output units in the range give more margin; on moderate grades the 380 is the lower-cost, lower-consumption answer.

Length, tyres and the descent

Overall chassis dimensions are 11,550 (10,400)×2,545×3,475 mm on a 1,800+4,700+1,350 mm wheelbase. That is a long truck, and the turning circle that comes with it is the price of the body. Walk your route — bench widths, tip head room, site access — before committing, because a truck that needs three shunts to position costs you on every load. The frame is 225/320×90×(8+7) mm with leaf springs at 11, 11 and 14, which is consistent with the duty.

Tyres are 13R22.5 18PR mixed and drive across thirteen wheels, with UC, Z8 and NP tread options and axle options Q4, Q2, Q6, SB8, SB9 and SBA. Choose from your ground and your site-to-road split, and check local availability of the 22.5-inch size before delivery. Braking is air brakes, front and rear drums, with ABS. Drums are right for off-road work and cheap to reline, but at 60 tonnes their weakness — heat — is amplified. Select the gear before the gradient and let the engine hold the truck. The sheet lists no engine brake or retarder, so ask whether one can be specified.

"Walk the route before you buy an 11.5-metre truck. Bench width and tip head room decide whether the length earns or costs."

Cab, and what is standard here

The cab is a right-hand drive flat-roof unit seating two, and one item differs from its siblings in this range: air conditioning is listed as manual rather than automatic. Everything else is comparable — power windows, central locking, remote lock, five-in-one lock, a standard airbag seat, manual mirrors, and MP3 + radio + USB with no radar. Two seats and no bunk means single-shift operation, and satellite positioning is optional: specify it at order stage if your dispatch needs telematics.

The airbag seat remains the most important comfort item on a truck that works broken ground all day, and manual air conditioning is perfectly workable — it simply asks the driver to adjust it. If driver retention matters in your market, ask whether automatic climate control can be specified. The 350 L aluminium tank is standard here as across the range, and a desert air filter is optional and worth adding if your site is dusty, since it protects the turbocharger and helps keep service intervals long.

Shipping an 11.5 m truck, and the compliance question

At 11,550×2,545×3,475 mm, this unit is comfortably outside what fits a standard container, so it normally moves by RoRo or on a flat rack rather than boxed. The listing shows $61,773 with an FOB Tianjin/Qingdao RoRo figure of ¥341,673; the FOB RoRo quote covers rolling the vehicle onto a vessel at a named Chinese port, and ocean freight, insurance, destination charges and duties come on top. Shipping class and cost depend on your discharge port and the service running at the time, so send the dealer your destination port and get the method, freight component and documentation confirmed before placing a deposit.

The sheet records no emission standard for this build. If your market requires a certified emission level, ask what documentation ships with the vehicle and whether an equivalent-certified configuration is available. It is also right-hand drive, so confirm RHD is registrable where you operate, and check that 60,000 kg and these axle loads fall inside your local licensing class.

Questions buyers ask before signing

It is the largest body in this range and is aimed at light, voluminous material such as coal, aggregate and overburden, where you run out of volume before reaching 60,000 kg GCW. With dense ore you will hit the GCW and the 9 T front and 16 T rear axle limits with the body barely half full, and from then on you are carrying dead weight and length.

Can an 11.5 m right-hand drive dumper ship easily?

Overall dimensions of 11,550×2,545×3,475 mm are outside what fits a standard container, so this unit normally moves by RoRo or on a flat rack rather than boxed. RHD, manual air conditioning and the 350 L aluminium tank are as specified, while shipping class and cost depend on your discharge port and the service running. Send your destination port and confirm the method, freight and documentation before depositing.

What should I confirm that the sheet does not state?

Whether an engine brake or retarder can be specified; the ratio spread and top-gear ratio in the Fast Gear 12JSD180TA; which axle and tyre options are available for your build slot; and the warranty terms and service intervals for the ISG 380 and the gearbox.

Our read: this is a volume truck, and it should be bought only by operations whose material is light enough to fill it. If that describes your work, the 9,450 mm body and the torque plateau make a productive combination. If it does not, take the shorter body and save the length. Either way, settle the emission and registration questions before anything else.

With those answers and a landed figure for your discharge port, the decision is straightforward. The Auman EST 8x4 dumper page carries the full sheet.
