Not necessarily tower footings, but definitely terminals. Need more concrete in the ground to hold the extra tension.
Although it may not be necessary, Poma's terminal foundations are pretty standard for the moving terminal detachables. Both top and bottom terminal foundations tend to be nearly identical except with regard to height, but that has more to do with the profile of existing ground. They also tend to be the same regardless of drive location, but then again I haven't really seen foundations for larger poma lifts, and maybe they keep them standard for other reasons, and use oversize foundations.

Often the customer wants different heights at the top and bottom, so the foundations end up being similar but different in height and volume. 95% of the foundations are under ground and typically they are bigger at the top although the same shape. I know the FG Poma (alpha) are different as well.

It has changed on the new LP stations, as one has the bullwheel behind the central post, and the other terminal in front.
