  • Road roller
    Patent number: 5664909
    Abstract: The invention relates to a road roller primarily for compacting road surfacing materials such as asphalt. The road roller provides an ergonomic workplace for the operator in the cabin of the road roller and offers an unobstructed view of the rollers (4 and 12) and especially of the lateral edges (4a and 12a), respectively, thereof. This is of major importance when positioning the road roller on the surface to be compacted. This is achieved with an asymmetrical arrangement of the cabin; that is, one side of the cabin extends beyond the lateral edges (4a and 12a), and the operator's seat 6, with the steering wheel 7 and controls 8, is pivotally and laterally displaceable within the cabin.
