  • Answer

    In the definition of the carrier geometry in mask 1.2, the option "Vertical stiffeners at the end of the carrier" is activated as standard in the tab "Stiffener". Proceed as follows
    • In Mask 1.2, open the "Stiffen" tab and deactivate the option (Fig. 01)
    • Now you can deactivate the stiffeners in column K in the "Storage" tab (Fig. 02)
    • In mask 1.4 "Load", the carrier buffers can now be deactivated (Fig. 03)
    Now the overhead crane can go beyond the beam ends.

  • Answer

    To determine the maximum support forces, it is often necessary to allow the crane to overrun the designed girder. In this way, it is ensured that in the case of asymmetric load distribution, for example, every wheel really runs over the critical location of the girder.

    However, if there are girder buffers to prevent the crane from moving out on the left and/or right end, the distances bL and bR can be entered in both text boxes. This also reduces the number of generated load combinations.

    If necessary, you can specify an eccentric arrangement of the buffers in a dialog box by using the [Details] button (see the figure).

    You can find more information about the design of craneway girders in the webinar under Links.
