A transfer trolley is installed in a lower part or at a side of an upper slab(10) of a bridge to check the bridge, and a guide rail is longitudinally arranged and mounted in the lower part or the side of the upper slab. A roller(30) is cylindrically formed, turned and moved along the guide rail to support load of the transfer trolley. A cage(40) is combined with the roller to go on board. A protruded part is combined with the guide rail, and the guide rail is composed of an assembling unit longitudinally and continuously combined with the protruded part and a rail guide part(24) installed in a lower part of the assembling unit. |
