New GRW 280 pneumatic roller has an operating weight between 10 and 30 tons. Operating station now has only one seat, not two, which is adjustable and allows the operator more freedom of movement. The seat can optionallly be moved and pivoted at the side toward the machine’s out edges and along with the console. A hydrostatic rear-axle drive allows for higher speeds during transport and compaction. To match it, the newly conceived steered axle at the front with disk brakes ensures the necessary braking force and thus considerable safety when braking suddenly, even with maximum load. The unit has large ballast spaces between the wheelsets, and a serrated frame that is open in the downward direction. It can be filled with steel or concrete using a forklift truck to be ballasted from 10 to 30 tons.
