Aerial Ladder as High Directional or Crane
been a bit since i've posted much up but i've got a couple more questions to see what others are thinking....
? #1: Do you use your aerial as an HD and/or Crane?
I'm looking into what other departments do for SOP's so we can develop ours where I work. We have various ladders in the city, straight sticks, buckets with 250-1000# tip load, from 75-110' in length.
I see that there is value in using them as both an HD and a crane. I looked into the laws regarding using them as a crane and have found no OSHA rule, CFR, state law, state administrative rule, manufacturer rule, or nfpa recommendation that would forbid this. The only thing definitive that i've been told is don't exceed the tip load by the manufacturer (pierce) and that the aerial doesn't know if the weight is on the top or hanging from the bottom of the ladder.
If you have thoughts, detailed rigging methods, physics discussions, i would like to discuss them so i can present ideas to my department.
