<P>PROBLEM TO BE SOLVED: To provide a rail lifting system which can be efficiently attached to and detached from a rail. <P>SOLUTION: The rail lifting system 1 is provided with a first member 3 and a second member 5 which are rotatably connected to each other by the intermediary of a connecting shaft 7. The first member includes a fitting part 9 to which a traction means 53 is fitted, and pressing parts 11 abutting on front sides of the rail 51 upon traction. The fitting part and the pressing parts are positioned on a first virtual extension line 13 and a second virtual extension line 15 extending from the connecting shaft in a side view. The first virtual extension line and the second virtual extension line extend in different directions from the connecting shaft. The second member is formed so that it extends along the side of the rail and then goes around the back side of the rail when the connecting shaft is positioned on the front side of the rail. <P>COPYRIGHT: (C)2012,JPO&INPIT |
