A port tractor is bought on arithmetic that has nothing to do with horsepower badges. It is bought on trips per shift, turning circle inside a crowded terminal, and how much the truck costs to keep idling at a gate. The Auman ETX 4x2 port trailer line is offered here in exactly three diesel specifications, listed at USD 30,268, USD 33,516 and USD 40,502, all on a 4x2 layout with Fast gearboxes. Three variants is the right number of choices for this job — but the differences between them are sharper than the price gaps suggest.

Why a 4x2 is the right answer inside a terminal

Start here, because it is the decision that governs everything else. For paved terminal and quay shuttles, a 4x2 keeps tare, tyre count and turning circle down, and those are precisely the things a port cycle rewards. Two driven wheels instead of four means less scrub, fewer tyres to replace, lower rolling resistance and a tighter circle in a yard where every metre of swing costs you a container slot.

The reverse side is honest and should be said plainly: if your operation goes off pavement, climbs steep gradients, or works ramps with laden containers, you want a 6x4 instead. A single driven axle has limited traction when rail or water is involved, and a port that includes unpaved stacking areas will expose that limitation within a season.

The three specifications side by side

At USD 30,268, the BJ4182SLFHA-AB is a 270 hp Weichai WP7.270E51 with a Fast 9JS119 nine-speed, on a 3,400 mm wheelbase, measuring 5.932 m long, 2.49 m wide and only 2.96 m high. That height is the key figure: with a high-roof cab it is still under three metres, which matters if your route passes under terminal gantries, low canopies or older warehouse structures.

At USD 33,516, the BJ4183SLFKA-AA steps to a 280 hp Foton Cummins ISGe5-280 with a Fast 9JS135, on a 3,600 mm wheelbase, at 6.16 m long, 2.495 m wide and 3.41 m high. This is the specification to look at first if you want the Cummins rather than the Weichai, or if parts and service support for Cummins engines is stronger where your terminal sits.

"Choose the 270 for light and medium containers on flat ground. Move to the 350 when the work involves heavier boxes or ramp gradients."

At USD 40,502, the BJ4183Y6ADS-01 Basic Model is a 350 hp Weichai WP10H350E62 with a Fast 12JSD180TA twelve-speed, on a 3,600 mm wheelbase, at 6.135 m long, 2.55 m wide and 3.41 m high. Twelve gears rather than nine, and eighty more horsepower — the combination for heavier boxes and ramp work. Note that this one is the 2.55 m wide body, so check it against any width-restricted access gates.

The maintenance claim, and how it translates into shifts

The manufacturer states that the 10.5-litre engine is rated to a 100,000 km maintenance interval, and that low fuel consumption, high reliability and long service life are the design targets across the range. For a port tractor running short, repeated cycles, a 100,000 km interval usually means one planned stop a year rather than several — which is the single most valuable figure here, because a tractor out of a terminal costs more per hour than a tractor out on a highway.

Treat that 100,000 km figure as the manufacturer's rating and verify how it applies in your duty: high idle hours, dust and constant low-speed shuffling are hard on oil in ways that distance-based intervals do not capture. Agree parts stocking at your port before delivery, because the difference between a one-day and a one-week stop is usually a component sitting on a shelf.

Why the local quote column is blank

You will notice the "local minimum quote" line reads Inquire for all three variants, and that is worth understanding rather than dismissing as evasiveness. The shown figures of USD 30,268 to USD 40,502 are manufacturer suggested retail prices; the real number depends on order quantity, configuration and destination, and ocean freight, insurance and port charges are not included in any of them.

"Send your discharge port, fleet size and duty cycle, then compare the landed cost against local alternatives. Comparing the MSRP to a local quote is how fleets misjudge this class of purchase."

For a port fleet ordering several units at once, quantity is likely to matter more than any specification choice, so put the whole package — units, destination and spare-parts set — into one enquiry rather than asking for a single-truck price and hoping it scales.

Which port duty each variant suits

For intra-port shuttles between quay and stacking area on flat paved ground, the 270 hp nine-speed is the economical choice — it is the cheapest, the shortest, and the only one under three metres tall. For operators running beyond the gate to inland depots or neighbouring terminals, or anyone whose duty cycle includes loaded ramp gradients, the 350 hp twelve-speed earns its extra ten thousand dollars quickly.

The 280 hp Cummins sits in the middle and buys something different from either Weichai: brand familiarity and service support. If your workshop already runs Cummins tooling and diagnostics, that is worth real money in reduced training and faster fault-finding — often more than twenty horsepower is worth. Against a European yard tractor costing several times these figures, what you forgo is cab refinement and resale strength rather than capability; whether that matters depends on how long you keep the truck and whether you sell it inside your own market.

What this record does not tell you

This is a short sheet, and the omissions are substantial. There is no gross vehicle weight, no gross combination weight, no fifth-wheel or axle ratings, no torque figures, no engine displacement for individual variants beyond the stated 10.5 litres, no tyre specification, no fuel tank capacity, no cab detail, no turning circle and no fuel consumption figure. We quote none of them, and every one should be obtained in writing before you build a container plan around this tractor.

No warranty term or after-sales commitment appears either, and no sales country is recorded — so homologation for your port authority, RHD or LHD availability, and shipping arrangements must all be confirmed before ordering. Everything above comes from the variant table and published material for the Auman ETX 4x2 port trailer and nothing else.

Questions buyers ask before signing

Is a 4x2 tractor really enough for container port shuttles?

For paved terminal and quay work, yes: 4x2 keeps tare, tyre count and turning circle down, which is exactly what port cycles reward. The 270 hp Weichai and 280 hp Cummins with nine-speed Fast gearboxes suit light to medium containers on flat ground; the 350 hp WP10H350E62 with the twelve-speed handles heavier boxes and ramp work. Off pavement or up steep gradients, buy a 6x4 instead.

Why does the local minimum quote read Inquire?

The figures shown, USD 30,268 to USD 40,502, are manufacturer suggested retail prices for the three specifications. The real number depends on order quantity, configuration and destination, and ocean freight, insurance and port charges are excluded. Send your discharge port, fleet size and duty cycle and ask for a landed cost you can compare against local alternatives.

What service interval can a port operator expect?

The manufacturer rates the 10.5-litre engine to a 100,000 km maintenance interval, which for short repeated port cycles usually means one planned stop a year rather than several. Verify how that rating applies to high idle hours and dusty low-speed work, and agree parts stocking at your port before delivery rather than after the first breakdown.

Which of the three should we put into tender?

Match it to the ground, not the budget. Flat paved intra-port shuttle: the 270 hp at USD 30,268, helped by being the only variant under three metres tall. Heavy boxes or ramp gradients: the 350 hp twelve-speed at USD 40,502. Cummins support already in your workshop: the 280 hp at USD 33,516.
