PROBLEM TO BE SOLVED: To provide a railway working truck that corresponds to various types of track rail having different gauges of a track. SOLUTION: The truck has a pair of forward and rearward guide rails 2, 2' installed in parallel to each other at the lower surface of a base table 1 and a pair of wheels 3, 3 moved along the guide rails 2, 2' are arranged at each of the guide rails 2, 2'. Then, one end of an intermediate piece 12 having the other end rotatably connected to each of the opposing sides of the pair of wheels 3, 3 is rotatably connected to the end of a connecting piece 11 rotatably pivoted at the base table. Further, running wheels 7 running on track rails 13 are rotatably pivoted at each of the wheels 3. When the gauge of the track is changed wide or narrow, the connecting piece 11 is rotated to enable the running wheels 7 to change the gauge of a track. COPYRIGHT: (C)2007,JPO&INPIT
