About 10 years ago I was project manager/site forman for a company that specialized in installing high end modular homes. These homes were set on full foundations/basements. One of my jobs was to oversee the installation of the support columns that held up the boxes as we called them. A typical box was about 70' long and 15' wide with at least two boxes per story. The columns had to be exactly in place per the prints and dead plumb. As you can imagine you had to be under the suspended box to perform this task. I was responsible for this about twice a month for just over three years.
During one of the sets of a two story home, the first of two second story boxes was being lowered into place when I noticed that a bundle of cable had not be dropped from it's location in a stud bay. This bundle was to be fed down a first floor wire chase in the middle of the box. This chase was to small to climb later and the wires were supposed to just drop in place while lowering the box. As the box was almost in position I gave the hand single to stop the lift and lock all controls. The box stopped about three to four feet from it's final resting place. I grabbed a hammer and crawled in between the already set first floor module and the suspended second floor module and released the cable bundle. I then proceeded to scurry back out.
This lift was being done by a very similar crane to the current one being used in the FF lifts. Although, smaller in size.
I think this is very similar to fear of heights of claustrophobia. These things either bother you or they don't. Kind of like doing a heli charter photo update with the doors off. :thumbs:
End of story.
