OK, so that first segment, where he has to clear the top of the structure by coming out the side? Yikes. And then, it's like, "OK, cool, he's there, man that was crazy," and the narrator says, "At this point, he still has another 60' to climb to get to where he needs to be." Dang. Working at cloud-level... There's gotta be some sway up there, too...
I know next to nothing. I am frequently wrong.
First it is very tiring to climb that high. It is probably harder to climb ladders than to climb the equivalent amount of stairs, which would be a LOT of stairs. I've climbed a 150' ladder, up the inside of an enclosed tower, and I had to stop halfway up and rest. And I consider myself in reasonably good shape from biking. I was climbing a ladder in the middle of the tower but it wasn't so scary partly because it was dark in the tower and I couldn't see things below me and also because I had a sliding safety device that moved up the tower with me.
Second I have a problem climbing ladders that are straight up because of my long legs. My knees hit the ladder so I have to lean out more than I like and that puts more stress on my hands to keep me from falling backwards away from the ladder. Another time I climbed partway up a tower crane and at one point to get over to the building I had to try to climb up the sloping diagonal on one face of the tower and then step over to the gangplank sticking out of the building. Climbing the ladder part was easy, getting another 5' up to the level of the gangplank was harder.
I can't believe they don't have better climbing aids at the top of the tower. It changes from a tower with a ladder to an odd triangular tower where you climb on the structure itself, and then to a couple of different solid round pipes with various ladders on the outside. I wonder why it couldn't be the same type of tower all the way up.
I am surprised they don't have a safety bar all the way up for the whole climb.
I used to have to work the top of the mast and the yardarms of the Navy ship I was on... not nearly as tall a climb as that shown in the vid, but high enough. Climbing the mast I wore a harness and a climbers safety rig that slid up a pole in the center of the ladder... if for some reason I lost my grip, the safety system would only let me fall a few feet before it would latch a brake and stop sliding. We used to call the thing a "nut buster" because the safety line when right down the center of the ladder and you had to keep moderate tension on the system while climbing to hold the brake off.
When I would finally reach my working area, I had two tethers, one of which was always attached while I moved about. I was always attached in some manner.
I see this guy is just moving about freehand... yikes. and sometimes he latches on. wow.
