The bridge by steel box girder of regular welded, girders and Taiwan, etc. The car was laid for the girder of rail operation. Two of the girder with walk. Side for installation and maintenance during operation. The other side of the car for installation and conductive device. In view of the hanging below the control room, manipulation of indoor and individual controller with linkage console, room with Taiwan with inclined ladder, walk in the middle of the girder connection with joint at both ends of the beam. Traveling mechanism driven by respectively. Crane wheels for the big four wheels and rolling bearings with the angular bearing assembly installed on the client after both ends of the beam. Crane car by lifting mechanism and the car run institutes. This crane span for 14m, car 3m cart, weight lifting, Lord 40t 10t hoisting working level, and speed as A3 cart 1-10m/s, car for 2-20m/s. The actual requirements of crane. Key words: bridge, During operation, Cars run, Girders, End, Walking machin 绪论 被人们誉为“巨人之臂”，“
