Hey dude
The two I was on we had to climb on the outside around the little hut. Then we climbed down through the center of the crane to the end. There was no metal mesh grate to walk or crawl on. Lots of grease though have fun. JOMAN
Dude
You also have to look at if you want to do that object more then once. We us to day blaze this spot all the time did it for a year or so. Now there is video Surveilance and we can no longer do it in the day just something to consider. JOMAN
