From memory it flew on six cables, each ~1.25" OD & routed over 12 two
foot diameter sheaves.
They were essentially flying an enormous pair of drawer slides and the mansion was the drawer. The floor of the mansion was raked and housed parts of three LX pipes within it to light scenes beneath both when it was partially elevated as well as when it was totally out of sight.
There were six vertical I beam tracks forming the onstage edges of ~the 2nd, 4th, and 6th legs.
Remember
stage level was three stories above grade.
The six vertical I beams went down to solid bedrock, passing through second story offices and
ground level tourist traps along the way.
Their upper ends passed through the first and second grids ending at the
tertiary grid.
One two
foot diameter
sheave topped each of the six verticals.
USC six more vertical I beams also began at bedrock and ended at the
tertiary grid, with each vertical supporting another two
foot diameter
sheave. Again from memory, USC was a
counterweight carriage ~six feet wide supporting ~12 columns of ~fifty pound
stage weights.
USC at
deck level was a hydraulic
winch with an ~thirty inch diameter disc brake clamped by two pairs of hydraulic brake pads.
Most of the flown items were supported by the primary
grid with odd numbered pull lines and arbors SR of the mansion's counterweights and even numbered lines and arbors SL of the mansion's counterweights.
The 14,000 pound 'pool surround' + our 11,000 pound automated 'On The
Road' piece were supported by the secondary
grid.
The 20,000 pound two story mansion and its 20,000 pound counter weight were the only items supported by the
tertiary grid.
Three days were allowed in the
load-in schedule for us to get our piece up, assembled, tested, flashed out, ran several times, and the locals brought up to speed. We bought them almost two days by being up, assembled and darn near ready to rock the first day with less than two hours of flashing LX and speakers remaining for the second day.
The other four I flew with hit the bars and sushi establishments.
I invested my pre paid two nights in a downtown hotel and two days touring the three grids with a fellow from Feller who'd all but been living up there for several months.
I don't believe colleges and universities offered the equivalent of what I was exposed to in two days.
Toodleoo!
