A few comments from a professional climber with 31 years of experience:
1) Although it is easier, OSHA does not under any circumstances allow "free climbing". OSHA requires 100% tie off or you can be fined.
2) To call this video "Climbing a 1768 foot tower" is misleading. The first thing he says is that the job starts with an elevator ride to 1600 feet. The remaining 168' climb is a short climb for anyone who regularly does this kind of work. The actual height is not even an issue.作者: 苏新 时间: 2010-9-21 13:47:20
