Abstract
A road finisher including an undercarriage, a chassis, a hopper, a paving screed, and a lifting device for lifting the chassis relative to the undercarriage at least in a rear region of the road finisher. The lifting device comprises a rocker mounted rotatably around an undercarriage rotational axis at an undercarriage-side bearing surface and rotatably around a chassis rotational axis at a chassis-side bearing surface. The lifting device further comprises a length-variable adjustment member connecting a chassis-side link point to a rocker-side link point and configured to change a distance between the chassis-side link point and the rocker-side link point by changing its length to selectively lift or lower the chassis relative to the undercarriage. A distance between the chassis rotation axis and the undercarriage rotation axis is greater than a distance between the chassis rotation axis and the chassis-side bearing surface.
