REFERENCE SYSTEM FOR A TRACK WORKING MACHINE

摘要

REFERENCE SYSTEM FOR A TRACK WORKING MACHINE A reference system for a track leveling and/or lining tamper comprises a reference wire or cord whose end and measuring points are held on bogies connected to the machine and laterally pressed against a selected track rail. A clamping mechanism is associated with the reference wire or cord and is fixedly connected to one or more of the bogies for selectively reducing and increasing the effective measuring length of the reference wire or cord between the end points thereof.
