Aerial Ladder as High Directional or Crane

    Michael, you got it.

    OSHA state means that the state has stood up their own OSHA program at the state level that enforces OSHA or HIGHER standards. The state OSHA will handle the workplace safety and accident investigations.

    Non-OSHA states do not run their own state OSHA, though they may cover workplace safety under some other department. They fall under the same federal standards and will be investigated by federal OSHA for workplace accidents. It is sort of a misnomer, the non-OSHA states fall more under federal OSHA than the OSHA states.

      Also, as I have consumed different and more training I have loosened up my views on the use of aerial ladder as a high help or "crane". I believe that if you are using your equipment within the confines of its abilities and have trained on the techniques, shoot go for it.

        Don't forget to change out your hydraulic parts every so often, or you could risk a catastrophic failure! We purchase adapters and other parts from Hydraulics Direct (here is their website), but we've also ordered from Parker in the past.

          So I'm digging up an old, and much controversial article. After some discussion in a recent class, I had another thought about this subject. I don't profess to be an aerial guru, nor in the subject of technical rope rescue. I've been blessed to train with and meet some really great guys in rope rescue, and they all seem to have a little different opinion on this topic. Outside of the OSHA standards, (blah blah blah) my question dabbles a bit in physics. The latest theories state to use a directional pulley at the aerial tip, and build the MA off the outriggers, down the aerial bed, etc. I understand that this pushes the resultant back more in line with the aerial, versus hanging a pre-rigged MA off the tip. Understandably, and I'm repeating myself, this is to place the aerial in compression. My question is this: to my understanding aerials are designed to maintain their strength as a truss type system, where the top of the aerial is in tension and the bottom is in compression. Hence the reason we support the aerial at the rear (lift cylinders) and do not rest the tip on anything. So when we drive the resultant down closer to the aerial, does there come a point we place too much compressive forces on the aerial and defeat the 'truss type' strength? Obviously this would be more evident when the aerial is extended.
