GUIDANCE DEVICE FOR A TRACK-FOLLOWING VEHICLE AND METHOD OF GUIDING A TRACK-FOLLOWING VEHICLE

摘要

A guidance device for a track-following vehicle has a guide wheel (22) which is complementary with a substantially circular guide rail (7), and which is capable of pivoting about the guide rail (7) from rotation about a substantially horizontal axis to rotation about a non-horizontal axis. The guide wheel (22) is pivoted by a pivoting member (32) to which the guide wheel is mounted, and the guide rail (7) extends parallel to the main rails (2).
