Rising volumes of traffic, heavy vehicles and increased mobility take their toll, particularly on streets and roads. With special solutions and specially developed equipment, HEILIT+WOERNER Bau GmbH in Munich is the leader in the sector for concrete road surfaces. Several million square meters of concrete pavement are built every year in Germany alone. SENNEBOGEN supplied a SR 25T as a carrier vehicle for a new road base finisher. The multifunctional device is now used with a paving screed for bound and unbound road bases and combines several work steps in one. The material can be distributed precisely over large areas via the boom. Hydraulically bound and unbound road bases are laid in the correct position and height with a paving screed up to 8 m in width and equipped with compacting plates. Complex technology ensures precise positioning right down to the exact millimetre.
For the driver, this means simply distributing the material using the scoops. The drive and levelling functions run automatically. The paving screed is levelled via additional hydraulic cylinders mounted on the undercarriage. The position and height of the machine can be controlled precisely down to the exact millimetre based on a digital terrain model and with tachymetric positioning. This means that the building material is heaped up to a width of eight meters, straightened, levelled and compressed at the same time in one work step. The people responsible for choosing a SENNEBOGEN carrier machine for this task don't regret their decision for a second. They praise in particular the robust, mechanical construction and easy handling of the hydraulic and electric attachments. Despite its small size, the SENNEBOGEN SR 25T offers optimal stability thanks to the telescopic crawler chassis. This means that a three lane stretch of motorway can be prepared in just two work steps.
"SENNEBOGEN gave us exactly what we need for our special machines. The machine is compact, yet still extremely powerful. The easy access for maintenance work in particular makes servicing easier in everyday operation", praises Andreas Geier (technician responsible for road base finishers at HEILIT+WOERNER)
