Answer:
The CRANEWAY program can only design the main girders, not the bridge crane itself. The endcarriages of the bridge crane are also not designed.
For an overhead crane, you can define the parameters of the rail cross-section as well as an additional cross-section in Window 1.3 of CRANEWAY.
For a splice, you can define the width a and the height b. Beam cross-sections made of rolled or welded sections can be combined with a rail or a splice. If the rail cross-section is too large or the girder cross-section is too small, you can only continue the entry with a plausible crane girder section.
Angled and channel cross-sections are possible as additional cross-sections. They can be selected as beam cross-sections in the [Library] or defined using the button.
