That's a good question that I don't have the answer to, unfortunately. All I can say for sure is that the unit is the permanent one for servicing the spire (for cleaning, light replacement, or glass repairs). Beyond that, I don't know if they plan on disassembling it when they don't plan on using it or not. Honestly, after construction is complete, that won't be an easy operation at all (the derrick crane was actually used to put it up there). For now, it'll be used to install lighting and glass on the spire itself.
