Frame-shaped device for retaining supporting system of e.g. agricultural vehicle, is transformed by driving supporting system into stable triangle over no-load point, where system is attached at center part between vehicle and other devices

摘要

The device is transformed by driving a supporting system i.e. supporting wheel, into a stable triangle over a no-load point. The supporting system is attached at a center part between a vehicle and other devices. The supporting system is attached at an inclined conveyor of a harvester, where axle distance between the supporting system and a main drive axle ranges from 800 to 2000 millimeters (mm). Independent claims are also included for the following: (1) a method for reducing wheel or axle load on a road (2) a method for reducing contact surface pressure on a road.
