Answer:
These load positions can be created with the RSMOVE or RF‑MOVE add-on module: In the model file under Downloads, there are two cases of moving loads (Crane A and Crane B). There are 50 load cases resulting for the moving loads only.
The load cases are then combined automatically. In the "Actions" tab, you can specify the effect of the load cases on each other. For this, the load cases for Crane A are assigned to Group 1 and the load cases for Crane B to Group 2. This means that all combinations of Crane A are mutually exclusive. The same applies to Crane B. However, the load cases of Crane A can be combined with the load cases of Crane B.
Further information on moving loads and the combination of actions can be found in our manuals.
