June 11, 20223 yr Moderator This is scary, both for the helicopter pilot and the antenna crew! Although I once owned a tower company, and later a Land Mobile radio company, there is no way I would worked with this crew. Watch the man who climbs up to disconnect the lifting harness from the top section. He "free climbs" on the pegs and never uses his safety harness until he reaches the top! Fr.

June 11, 20223 yr Those Sikorsky heli cranes are amazing! Pretty insane stuff! Sometimes see the big Sikorsky’s over the Ford Assembly in Oakville. No room for error! Latest video at The Flight Level Flight Over Frozen Lake Erie - Between Ice and Clouds - Ultimate Solitude - The Perfect Memory
June 12, 20223 yr Author Moderator Each of those sections houses at least two and possibly four actual antennas. Altogether the two masts on the top of the Sears tower host 15 TV antennas and six radio station's antennas. Fr.

June 13, 20223 yr I would not want to attempt that on a windy day. Noel The tires are worn. The shocks are shot. The steering is wobbly. But the engine still runs fine.

Noel One of the top man's tasks was to purposely shake the top mast section to help the rest of the crew to finish bolting the flanges tightly! You can see him shifting his weight to cause it to 'rock'... Yikes! Fr. Bill AOPA Member: 07141481 AARP Member: 3209010556 Avsim Board of Directors | Avsim Forums Moderator
June 14, 20223 yr Check out the old skyscraper construction videos from New York City Father. These dedicated men not only erected steel, they were the ones doing derrick crane jumping, moving them up two floors at a time with no harness, and take them apart way up there on top when finished.
June 14, 20223 yr On a windy day the air currents around the buildings are unpredictable. When I was going to weather forecaster school at Chanute Air Force Base in Rantoul the instructors often talked about that. And about how Sears Tower can sometimes create it's own weather on such days.. Noel The tires are worn. The shocks are shot. The steering is wobbly. But the engine still runs fine.
