Frequently Asked Questions (FAQ)
AnswerWith the add-on module KRANBAHN, only the main girders, but not the gantry crane itself, can be detected. Also, the head girders of the overhead crane are not detected.In the case of an overhead crane, the parameters for the rail cross section and an additional cross section can be made in the mask 1.3 of the additional module.For a tab, the width a and the height b should be specified. Beam cross-sections made of rolled or welded profiles can be combined as desired with a rail or lug. If the rail profile is too large or the carrier profile is too small, the input can only be continued with a plausible crane rail carrier profile.As additional profiles, angle and U-sections are possible. They can be like the cross sectionsSelect the carrier in [Library] or define it with the button.There is already an interesting webinar on the subject " Dimensioning of crane runways according to Eurocode 3 " on our homepage.
In the standard EN 1991-3 the load groups 1-10 are given in Table 2.2. These are to be equated with the designation of the classes in our software.
The inclusion in categories AE is a Dlubal own name.
Category A: Limit state of carrying capacity> Table 2.2 of the standard: ULS (1-7)
Category B: Test load (8)
Category C: Extraordinary (9,10)
Category D: Limit state of serviceability (11-13)
Category E: This was included in the combinatorics on customer request and should be used for the load cases in which bearing forces from the crane runway calculation are to be combined with the further construction.
In our Knowledge Base article it is pointed out that the combinatorics (classes AD) is to be used for the preliminary design of crane runway girders For the supporting construction (consoles, supports, bars) this combinatorics is not to be used.
In your case, the bearing loads from the crane runway calculation would only be considered in category E.

AnswerNo, our current licensing system, regardless of the physical (Hardlock / USB copy protection plug) and the digital (Softlock) software protection variant, unfortunately has no borrowing function.
In contrast to the physical variant, the digital software protection technology additionally holds a "Rehost" function for transferring the digital software protection system from one computer to another. However, this transfer does not imply a transfer of a single license for a particular program from our product range but from the entire licensing that is governed by affected "softlock". The transfer of the digital software protection to another computer corresponds to the replacement of a physical copy protection plug to another computer.
AnswerThe dialogs in the Dlubal programs are optimized for the display size in the control panel of 100%. You may be able to correct the problem if the display size in the Control Panel is changed to 100% (see Figure 1) or / and a higher resolution is set.Remedy could also be the deactivation of scaling at high DPI values. To do this, open the properties by right-clicking on the program icon. Under the Compatibility tab, check the box for Overwrite high DPI scaling behavior. Scaling performed by: and select the setting application from the drop-down box. Then accept the change and confirm with OK (see Figure 2).
AnswerThe 10 S classes to be defined in screen 1.4 (S0-S9) refer to the Krahn track. It is not possible to enter the 12 S-classes (S01, S02 and S0-S9) for cranes.There is already an interesting webinar on the subject " Dimensioning of crane runways according to Eurocode 3 " on our homepage.
When I import the authorization file I get the error that the authorization file can not be copied to the destination folder. What should I do?

The user must have read and write access to the destination folder. This folder is specified in the error message (see Fig. 01).
Please set the required permissions on this folder. To do this, select the folder and call its properties. In the "Security" tab you can then z. For example, set Full Control for the Users group or for selected users (see Figure 02).
It should now be possible to read in the license file. The required user rights can also be found in the user rights document, which is available at the bottom of the downloads .
Alternatively, you can start the program as an administrator by selecting the "Run as administrator" command from the context menu of the program icon (see Fig. 03). Then read the current license file.
First, it should be checked whether a signal lamp lights up on the connected dongle (see Fig. 01). If it does not light up, try another USB slot, preferably directly on the mainboard of the computer and not on a USB hub or on the front of the computer. If the light is still off, try another PC. If the light does not shine, the dongle is probably defective and needs to be replaced.
If the light is on, please make sure you are using the latest authorization file. If that does not solve your problem, please send us a screenshot of the error message, a brief description of the problem and the diagnostic file (see Fig. 02).
I have problems with the installation of Dlubal Software programs. What could be the reason for this?
FAQ 002530 EN Installation RFEM RSTAB CRANEWAY RX‑TIMBER Glued‑Laminated Beam RX-TIMBER Roof RX-TIMBER Continuous Beam RX-TIMBER Purlin RX-TIMBER Frame RX-TIMBER Column RX-TIMBER Brace SHAPE-THIN COMPOSITE-BEAM
Installation problems often have the following causes:
- Antivirus software
- User rights
- Windows updates
AnswerThe title block of the printout report is created using the authorization file, which was used in the initial installation of our programs.
A subsequent change in the authorization file does not necessarily change all report headers immediately.
For the changed title block to be created as default in the authorization file, the "old" one has to be removed first.
To do so, please delete the file "DlubalProtocolConfigNew.cfg" in the following (default) directory:
While deleting the file, our applications must be closed!

The default settings are loaded for every new file. If you wish to change them, you have to create a new profile after making the desired changes and set it as "Default" (see figure). If you now start a new file, this setting remains saved. It is also possible to create several profiles, which can subsequently be loaded and managed.
