A major project worth around 21.5 million € is being implemented at Lake Reschen in the municipality of Graun in Vinschgau/Italy. In order to make the SS40 state road safer, it is being relocated closer to the reservoir. The gigantic project, which will be implemented in two construction phases over three years, started in April 2023. Numerous Liebherr machines, including 10 Liebherr TA 230 Litronic dump trucks, are involved and are responsible for both the earthmoving and execution of the backfill.

Efficient material handling with Liebherr dump trucks
The Liebherr dump trucks are assisting with the backfilling of an embankment on which the new state road will run. For this purpose, they are transporting excavated material from the bottom of the drained Lake Reschen to the operating location. The dam will be about 70 m wide and 20 to 22 m thick. This corresponds to approximately 2.5 million m³ of earth.
Franz Marx, Managing Director of Marx GmbH, is enthusiastic about the Liebherr dump trucks. Up to 28 t of material can be moved with the machines per loading process. A powerful drivetrain combined with automatic traction control allows the machine to deliver outstanding driving performance with concentrated pulling power. "The dumpers are proving themselves thanks to their outstanding operational efficiency. This increases our handling capacity and allows longer cycle times here on the construction site," says Marx.

TA 230 impresses with outstanding driving performance and off-road capability
Between the excavation zone in the middle of the lake and the unloading zones at the dam, an extra lane was laid down for the dump trucks in order to achieve high average speeds and thus guarantee high productivity during this large-scale project. Marx describes the ground conditions on the drained lakebed, which includes some slopes, as difficult in certain places. But even there, the TA 230 is proving its worth and demonstrating its enormous tractive power, even when fully loaded.
The reason for this is the optimal combination of a powerful engine, efficient drivetrain and maximum traction. Under the bonnet there is a 6-cylinder construction machinery engine with 12 l displacement and 265 kW / 360 hp, which ensures excellent driving performance. The machine has a top speed of up to 57 km/h in forward travel and up to 16 km/h in reverse. The efficient drivetrain consists of an automatic 8-speed powershift gearbox for optimal power transmission. The 6 x 6 permanent all-wheel drive and load-switchable longitudinal and lateral differential locks give the dump truck lasting traction, even on rough terrain.
Articulated trucks offer excellent driving comfort and ride quality
In order to work productively during long shifts, the Liebherr dump trucks are based on a machine concept that maximises driving comfort. According to the contractor, all machine operators at Marx GmbH have reported positively about this aspect: the TA 230 combines operator comfort with technical driving comfort. The operator's cab is generously proportioned and characterised by a modern interior design. Large glass surfaces, without pillars obstructing the view, ensure optimal all-round visibility from the cab. Staggered steps and a generous driver's door provide easy and safe access to the cab. Various storage areas, stowage compartments (one of which is air-conditioned) and bottle holders further expand the available space. The clearly and intuitively arranged control elements make the machine operators' work easier. Hydropneumatic shock absorbers on the front axle and the elastic suspension on the operator's cab optimally absorb the vibrations that occur during operations. The soundproofed cab reduces the interior noise level to just 72 dB(A).
