Advantages of the wheeled paver: transport under its own power at 20 km/h and high degree of manœuvrability
The Austrian construction company based in Linz relies on a VÖGELE SUPER 1803-3i wheeled paver. The reason: its sensitive steering facilitates the paving of tight bends whilst the all-wheel drive delivers a high level of traction. In addition, VÖGELE wheeled pavers can travel at up to 20 km/h under their own power. This means they can quickly reach job sites which even low-loaders find difficult. The wheeled undercarriage is also an advantage when repositioning, as demonstrated in the Tyrol. In this case, each carriageway was paved in the same direction, so the SUPER 1803-3i had to keep returning to its starting point. It completed this section more quickly than any tracked paver. Another advantage of the wheeled paver is an innovative option from world market leader VÖGELE, which increases the outstanding manœuvrability of the SUPER 1803-3i still further: the Pivot Steer steering brake. It automatically slows down the rear inside wheel hydraulically at maximum steering angle, reducing the outside turning circle to a modest 3.5 m. Without the Pivot Steer feature, this is 3 m larger.
Special feature: surface course directly onto base course
On the job site in Hochgurgl, the SUPER 1803-3i extended the helipad and hangar by two-thirds to create an area of some 4,100 m². This will enable up to four helicopters to take off and land in future. The location serves as a base station for air transport operations, rescue and emergency services and avalanche blasting. The asphalt structure of this air traffic surface differs somewhat from conventional road construction. Because shear forces such as those always occurring on roads from braking vehicles, for example, do not have to be taken into account, it is possible to dispense with the binder course. As a result, the surface course was paved straight onto the base course. The SUPER 1803-3i and its AB 500 TV Extending Screed ensured good precompaction and evenness of the surface, the screed compacting the layers using both tamper and vibrators. The two Swietelsky screed operators maintained layer thicknesses manually - 10 cm for the base course and 4 cm for the surface course.
