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.
