Abstract
A pushing device that can be attached to a road paver or feeder vehicle. The pushing device is attachable to a chassis component of the road paver or the feeder vehicle and comprises a pushing unit that is attached in a movable manner to the chassis component by means of at least a spring-absorber unit. The pushing unit can be displaced relative to the chassis component in a first direction and a second direction, whereby the spring-absorber unit has a greater spring rate during a movement of the pushing unit in the first direction than in the second direction.
