This document discusses concerns with a mobile tower design that links two towers with a deck and includes wheels. It questions how the towers would be braced to prevent falling over and notes that in one image, one of the tower's wheels does not appear to be well supported. The document also mentions that screwjacks could be used instead of wheels to adjust the tower height between jobs without needing to reposition the towers.

1. Two mobile towers linked with a deck – wheels on the towers are not a good idea. And how are the towers braced against falling?

2. This tower has been pushed to the side between jobs

3. One wheel is not very well supported

4. The screwjacks are adjustable in length so you don’t have to do this.
