Skyhook?

Not just a hook -- a sheave: This is part of a very clever force-rotating tagline setup, but we'll be here all day if I try to explain it.

Speaking for geekery fans, please do. I still do occasional tower gigs for the company for whom I used to work. Their tallest towers are a measly 180 feet, but I had to climb a 400-footer to remove a customer's gear once.

My rigging is beyond simple for these little jobs; just a couple of ropes and a sheave or two for changes of direction to avoid other gear on the tower. But I've watched with some interest and awe the guys from full-time tower rigging companies. Always interested in that. :)

I've got all day, go for it. Seems like an interesting subject.

Are you up here playing on the North campus today? Fun! :)

Consider this another vote for the detailed breakdown of the rigger's cleverness.

I've spent a fair bit of time this week watching the crew at work placing the new back-up generators and associated gear. Building the counter-weight for the 300 ton Liebherr was most interesting.

I think -- I hope! -- you'll be pleased with tomorrow's edition, then.

Makes me wish I'd gotten stills/video of them dropping the building over the first gen set. with two inches of clearance from the control building next to it. With winds gusting 5-15 mph.

I swear that crew could thread a needle with that thing.
