Company
History since 1960
From a service workshop in Wesel to the plant in Hünxe — and, with HELLMERS, a vehicle manufacturing tradition dating back to 1811.
KROLL and HELLMERS
Two traditions, one group
Seeking a more versatile product range, a stronger presence and even greater flexibility, KROLL Fahrzeugbau-Umwelttechnik GmbH acquired 100% of the shares in HELLMERS GmbH Fahrzeugbau of Wittstock/Brandenburg with effect from 1 June 2005.
Since this merger, the two companies have been jointly strengthening their position in the German and European markets — for sustainable, continuous growth.
