CRANE CARRIER TRAINED AS A BOX CARRIER

摘要

The invention relates to a box girder in which the web plates (3, 4) are formed from three individual plates (5, 6; 7, 7a, 7b), an individual plate (7, 7a, 7b) running through in one piece from the top chord (1) to the bottom chord (2), while the two other individual plates (5, 6) adjoin this first individual plate and in the process are welded to it by welds which can be produced from outside. The welding takes place in particular by submerged-arc welding. IMAGE
