Gammill 22, 26 and 30-inch machines come on a GS table, which feature a pivotal access arm, which can help with loading and smoothing batting.
This can be especially helpful if your quilt is on your frame as a full load, meaning the top is also attached to leaders and loaded onto a roller vs. floating the quilt top. Using the pivotal access feature, you can access the inside of your quilt sandwich to smooth batting.
