From The Files Of Transportbedrijf Schoones – A Trio Of End Dumps

Besides many impressive heavy-haulage combinations, the Schoones transport company has a fleet of end dumps, both in the form of straight trucks and semis. At the open house in September, their Volvo FMX 10×4 trucks were all neatly parked next to each other, and their semis were posing across the lot with a partly raised dump body.

We’re starting with one of the steel-nosed Volvo FMX trucks. It’s powered by the 12.8 liter D13 engine, maximum power output 469 DIN-hp. With a GVWR of 49 tonnes (108,000 lbs) and a payload capacity of 29.4 tonnes (64,815 lbs), this 2019 FMX is a very serious set of wheels.

What we have here is a traditional 10×4 configuration, that is with three steering axles and then two drive axles. The Volvo left the factory as an 8×4 chassis-cab, Terberg Techniek placed the center axle afterwards.

Other drivetrain options in this specific class are a 10×4*6 chassis (two steering axles, two drive axles, and a counter-steering tag axle) and the Dutch-only, 10×4 wide spread set-up (three steering axles, a drive axle, and last-but-not-least, a counter-steering drive axle). It’s not hard to figure out which of those three chassis choices has the shortest turning radius.

The truck is equipped with an insulated, JHS/Hyva steel dump body with solid covers and a load volume of 23 m³ (812 ft³). When transporting hot asphalt, the asphalt machine pushes the truck at the job, which explains those short, rearmost fenders.

Now let’s have a look at a duo of end dump semis. Unsurprisingly, with a Volvo tractor unit.

That’s quite a difference, the day cab of an FM(X), or this Globetrotter cab of the FH-series. Yet the engines are exactly the same, power-wise and all. The 2022 tractor comes with a 6×2/4 drivetrain.

The FH Globetrotter teamed up with a 2023 Schwarzmüller tri-axle semi-trailer. Comparable end dump trailers, almost always rolling on six super singles, can be found all over Europe.

The Schwarzmüller manufacturing company from Austria goes back to 1871, they offer a wide range of truck bodies, trailers, and semi-trailers these days. As an aside, anno 1955, full fenders and side underride guards were not quite in vogue yet.

Another FH 6×2/4 tractor, this one is from 2017 and has the standard, low sleeper cab. The shape of the headlamp units indicates that it’s an older Volvo FH, the truck maker’s full-size cabover model.

The white boxy unit, at the rear side of the cab, is a BMAir filter pressurization system. Usually, these are mounted on top of the cab. They keep contamination outside the driver’s compartment.

The 2023 semi-trailer, with a steel dump body and solid covers, is identical to the other Schwarzmüller. All things considered, legislation included, the payload capacity of this big-yet-short rig is 34.6 tonnes (76,280 lbs). Now you can calculate how many cubic feet of, let’s say, dry sand can be dumped into the dump body.
