When adding your machines, you are immediately asked to assign a transport class to the machine. You can find more information about transport classes here.
You can always change the transport class of your machine afterward in one of the following three ways:
1. By opening the machine
Navigate to "Machine Park" and click on the machine in question. Then, in the screen under "Transport," you can select the desired transport class.
Select the desired option from the dropdown and click "Save" at the bottom.
2. Directly from Machinery
Find the piece of equipment in your machine park (machinery). Click on the three dots (ellipsis) and select "Edit Transport Class."
Select the desired option from the dropdown and click "Save.
3. Bulk update multiple machines at once
Navigate to your machine park. Select the desired machines and then click on "Edit Transport Class" under actions in the yellow bar at the top.
Select the desired option from the dropdown and click "Save."
