MAN HydroDrive just keeps on going
The sites on which the trucks from Koller Transport/Gravel/Earthmoving (Vienna, Austria) work are demanding to say the least. Gravel pits with steep gradiants and construction sites of all sizes all around Vienna are the kinds of places where you’ll find Koller’s trucks. 80 percent of Koller’s fleet is made up of trucks from MAN, mostly 6x4 tractors. After serious consideration, and a series of tests, Koller took delivery of its first four dual-axle HydroDrive TGS units in 2009. In the medium term, the company even plans to replace its entire fleet with HdyroDrive trucks. “A direct comparison of the differently configured tractors showed a payload advantage of up to 1.8 tonnes with this new technology.” says company representative Günter Mayer, “We see that as a good reason to continue the migration.”
Efficient in any given situation
Efficient transport is just what Mayer needs. But increased payload alone is not enough to meet this goal - after all, what use would a HydroDrive-equipped truck be if it could carry more payload but couldn’t be relied on to actually work effectively? Happily, the HydroDrive trucks can be used anywhere without any problem and, when compared with a 6x4 tractor, they are a far more effective proposition on site. Wherever conditions get tight and muddy, MAN HydroDrive, with its added front traction, tends not to understeer and negotiates sure-footedly every bump and bend it encounters.
The list of benefits goes on. Koller often works outside of Vienna and needs to drive large distances to get there. Here too, Mayer prefers to use MAN HydroDrive trucks as, even on tarmac, less fuel is used compared to the company’s 6x4 tractors.
