high rise roofing

This year we are bidding three 22 story and three 27 story buildings ,three separate owners. last year we did three 12 stories and five 8-10 stories we used hydraulic swing hoists for removal and loading. We always had two men on ground with tag lines for trays or cargo nets. Elevator is out of question for four of the buildings and crane are out for three, has anyone used the hoists on the 27 story buildings your looking about three hundred feet of tag lines I have 170' cable on both hoist but I can switch out drum cable to 300'

Elevator maybe on two, all are tear offs three of the buildings are getting floor by floor gutted the freight elevator will be tide up and this is a occupy building so personal elevator are out. We done them before with the elevators and usually moving debris and materials one or two floors by hand
