The outriggers are extended to raise the hand girder until the first traveling means is positioned above the railway girder, and the first traveling means is moved along the hand girder at the front end in the traveling direction. A step (b) of moving to the vicinity of the part;
A step (c) of holding the railway girder using the holding means;
A step (d) of further running the hand girders and arranging the railway girders above the planned girder installation position;
(E) lowering the railway girder to the girder installation planned position using the holding means;
A rail girder moving installation method characterized by comprising: The outriggers are contracted between the step (b) and the step (c) or between the step (c) and the step (d), and the first traveling means and the second traveling unit are contracted. Lower the hand girder until the traveling means contacts the railroad rail,
Wherein in step (d), railway digit mobile installation method according to claim 1, wherein the moving the said hand total digits by using the first driving means and the second driving means. The rail girder moving installation method according to claim 1 or 2, wherein in the step (e), the outriggers are extended to fix the hand girders. The hand girder consists of a plurality of parts,
Prior to the step (a), after the plurality of portions arranged at a predetermined interval are connected to each other using a vertical pin, the vertical pin is removed, railway digit mobile installation method according to any one of claims 1 to 3, characterized in that coupling with the horizontal pin in proximity to a plurality of portions. Prior to said step (d), with telescopic backhoe excavator and conveyor truck, rail according to claims 1, characterized in that to remove the digit planned installation ballast material such as a position in any of claims 4 Girder moving installation method. In the step (d),
Temporarily stop the hand girder before the planned installation position of the girder,
Removing the railway girder from the holding means;
The first running means is moved in front of the girder installation planned position while the hand girder is run, and the hand girder is arranged above the girder installation planned position,
Elongating the outrigger to raise the hand girder and moving the first traveling means along the hand girder to near the front end in the traveling direction;
Is moved along the holding means holding the railway digits to the hands total digits, the railway digit claim 1, characterized in that arranged above the digit installation scheduled position to claim 5 The rail girder moving installation method described. Hand girders,
Outriggers provided near both ends of the hand girders,
Holding means for moving the girder along the hand girder while holding the rail girder up and down;
