Claims

[Scope of claim for utility model registration] A running girder that supports the rail on which the wheel numbers of an overhead crane are mounted, including a lower girder with an I-shaped cross section and an I-shaped cross-sectional girder placed on the lower girder.
a large number of elongated holes drilled along the transverse direction of the upper girder, at least one of the upper 71 flange of the lower girder and the lower flange of the upper girder; A large number of holes are drilled to face each of the long holes, and a large number of bolts are inserted through each of the opposing long holes and holes to tighten and fix the upper flange and the lower flange. It is characterized by one running girder on the ceiling. ′
