Gantry crane for transporting track panels

Abstract

A gantry crane for transporting track panels comprises a longitudinal beam extending in a longitudinal direction. The longitudinal beam includes lifting tools for gripping a track panel and is supported by chassis frames including in each case two vertical beams, having vertical adjustment drives, and two transverse beams connected to the vertical beams. The transverse beams extend perpendicularly to the longitudinal direction and have drives for transverse adjustment. Pairs of crawler tracks are fastened to the chassis frames for mobility of the longitudinal beam, each crawler track being connected to one of the vertical beams. Each chassis frame is designed to be rotatable relative to the longitudinal beam by means of a vertical axis of rotation which is disposed centrally between the two crawler tracks and connects the two transverse beams to the longitudinal beam.

1 . A gantry crane for transporting track panels, comprising: 
 a) a longitudinal beam extending in a longitudinal direction and having lifting tools for gripping a track panel;    b) chassis frames supporting the longitudinal beam, each chassis frame including: 
 1) two vertical beams;  
 2) two transverse beams connected to the vertical beams and extending perpendicularly to the longitudinal direction;  
 3) vertical adjustment drives associated in each case with the vertical beams;  
 4) drives for transversely adjusting the transverse beams;  
 5) pairs of crawler tracks fastened to the chassis frame for mobility of the longitudinal beam, each crawler track being connected to one of the vertical beams; and  
 6) a vertical axis of rotation, disposed centrally between the two crawler tracks and connecting the two transverse beams to the longitudinal beam, for allowing rotation of the chassis frame relative to the longitudinal beam.
