A TRAVELLING MACHINE FOR TAKING-UP AND/OR LAYING TRACK SWITCHES OR CROSSINGS

摘要

A mobile apparatus for laying assembled track switch and crossing sections comprises a bridge-like carrier frame supported at each end by a track-bound undercarriage and a track-laying undercarriage mounted independently of the track-bound undercarriages for pivoting about a vertical axis through an arc of at least 90 DEG and for vertical adjustment. A hoist is mounted on the carrier frame between the undercarriages for gripping and transporting the assembled track sections.
