Our success story

The KJ Sonderanlagen-Hebezeuge-Bühnentechnik GmbH company was founded in 2007 by Norbert Koglin and Jens Jankowiak in Potsdam. Both managing directors had previously worked together for 15 years in the field of conveyor technology and lifting equipment. Due to the successful development of the company, the company moved after only one year to Preußenpark in Ludwigsfelde near Berlin. From there KJ delivers conveyor and lifting technology all over the world. On 1/1/2019 KJ was taken over by the Schierholz Group in order to benefit from synergies and each other's know-how. With an equally strong partner at its side, KJ can further develop its technology.
