Gerken Group

Gerken is a unit of the Wabtec Group, one of the world’s leading manufacturers of stinger systems under the STEMMANN-TECHNIK brand.

Stinger systems are used to supply power to vehicles parked in maintenance areas, e.g. for battery charging or other maintenance work, which must be carried out with the vehicle powered. What’s more, with our Stinger systems, vehicles can be moved inside the depot or maintenance facility by means of a control panel.
