Feldmann AG makes use of the Aeolus AR28 tyres


In early June 2015, the Swiss leasing specialist Feldmann AG opened its Dietlikon site, creating another branch for the two areas of mobile cranes and (heavy-weight) transport.

“We only mount AR28 tyres on our Liebherr cranes”- Heinrich Kistler, dept. manager cranes Feldmann AG, Switzerland. 

Feldmann AG is one of the leading crane companies in Switzerland. Following the appearance of the new AR28 mobile crane tyre from Aeolus, the Swiss heavy-weight specialists have been among the first to fit the AR28 to their own Liebherr equipment, across an extremely wide range of tonnage classes. In the main sizes of 445/95R25 174F (16.00R25) and 385/95R25 170F (14.00R25), the Swiss company Aeolus covers the utility vehicle requirements for Feldmann's fleet.

Regular checks

On an ongoing basis, measurements are carried out on the tyres while fitted on the vehicles, in close collaboration with the technical field representatives of Aeolus by Heuver, and particularly by Helmut Haak (Aeolus) and Guido Oswald from Wilhelm & Dousse. This means that all the information concerning the wear pattern, driving behaviour and change in the compressed air is determined and documented, even in the case of long journeys on motorways and cross country.

As Helmut Haak stresses, the statements provided by the drivers are always important here as well, as these predominantly evaluate practical impressions of aspects such as driving behaviour in dry and wet conditions, as well as handling properties, braking behaviour and "emptying" the profiles after digging in the ground. The wear pattern, especially, makes it possible to draw conclusions as to the expected final operational performance - and, all things considered, the AR28 from Aeolus should be an increasingly impressive product here.

Cranes and heavy loads

The Feldmann fleet is made up predominantly of traditional AT cranes, mini crawler cranes, mobile folding cranes and loading cranes. The additional heavy-weight equipment consists of various tractor units and low-loaders or modular systems that can be combined for payloads up to in excess of 220 t.
