There is a helicopter in San Francisco grabbing things from the top of a skyscraper and lowering them down?pic.twitter.com/qFf6tc0LCY
It seems like replacing HVAC unit(s) on the roof by lowering the old one to the truck below, and then raising a new one.

that seems about right, “long lining” is the term they use. They’ll have a team on the roof and a team at the staging area. For longer operations they’ll also keep fuel at the staging area. That building looks 70s-80s ‘ish so probably getting HVAC refitted.
