I have a friend, a professional long arm quilter, who's machine is on casters. Casters are used to move the machine out of the way when not in use. She doesn't quilt in 17 different places in the room, she's got the floor marked for her specific spot for her quilting area. So the frame is balanced for that spot and just moved out of the way when not in use. She has a Gammil & the frame is very ridged & sturdy and seems to make the trip just fine.
