Bavarian contractor has novel approach

In the Southern German state of Bavaria a contractor is using an adapted machine from Sennebogen for concrete paving duties. Munich-based Heilit+Woerner is using the Sennebogen machine as a carrier vehicle for applying bases for road surfaces.

In the Southern German state of Bavaria a contractor is using an adapted machine from Sennebogen for concrete paving duties. Munich-based Heilit+Woerner is using the Sennebogen machine as a carrier vehicle for applying bases for road surfaces.

Sennebogen supplied one of its SR 25T models 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 allows the contractor to combine stages of work 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 8m in width and equipped with compacting plates.

The machine operator’s main task is to distribute the material, while the drive and levelling functions run automatically. The paving screed is levelled using additional hydraulic cylinders mounted on the undercarriage and the position and height of the machine is controlled using positioning technology that follows a digital terrain model. This allows the material to be laid to a width of up to 8m, straightened, levelled and compressed at the same time. Despite its small size, the Sennebogen SR 25T is also said to be stable in operation due to its telescopic crawler chassis, allowing a three lane stretch of motorway can be prepared in just two work steps.

    Rebuilding a runway requires special attention to detail to maximise efficiency and safety Airport runways face special challenges with regard to the loads they carry on a daily basis, particularly when aircraft are landing. A modern jet aircraft will typically land at speeds of around 240-260km/h, with a laden 747 weighing as much as 265tonnes at the end of a long flight. The stresses these large aircraft place on runway surfaces are enormous and not just with the massive impact forces exerted during
