The New Paxis Scaffold
Problem: Scaffold an 88 foot dome that has only 4 36″ standard doors?
Solution: Expand our already proven Polar Scaffold to fit that size of a dome.
We started by expanding the scaffold width to 10′. This has really made the scaffold a lot sturdier. We are still using the same end frames, but different cross pieces and longer planks.
Then we redesigned the beams so that they are interchangeable pieces vs. the other expandable left and right pieces. This makes them easier to carry around, and more versatile. With the shorter universal beams, we could easily make a scaffold for any size dome from a 20′ to 100′.
One of the biggest concerns was the motor. We were concerned that the existing motor would be perfect speed for the outer edge of the scaffold, but when we are spraying in the middle it would be too slow. Also, the motor has a tendency to stop abruptly making long scaffolds hard to stand on. We purchased, with AAA Electrics help, a single phase to three phase inverter that would also double as a controller for the three phase motor. Using three phase allows us to adjust the speed of the motor. The controller does a lot of cool things for us, best of which is it lets us control the accel and decel time so that we have smooth use.
The scaffold is now complete and is going to be on the jobsite Monday. I will post more pictures as they are available.
