PPP Project “A3 Steigerwald Autobahn“


Fast and accurate using a KEMROC chain cutter

While upgrading the A3 Autobahn in northern Bavaria, the Steigerwald Süd service area was to be increased in size which involved extensive trenching work. Civil engineers, EIFFAGE Infra Bau SE and JOHANN BUNTE Bauunternehmung GmbH & Co KG rented a 42-ton excavator with a KEMROC EK 150 chain cutter attachment to carry out the work. Even at depths down to nine meters, the chain cutter worked its way through the compact sandstone with precision to the nearest centimetre. Despite working in such difficult geological conditions, consumable costs were kept within reasonable limits.
