Correction: I stated that the aerial was a class 1 lever, but meant to say class 3. The fulcrum is at the base turntable, the effort is the hydraulic rams operating on mechanical disadvantage in order promote speed of raise, and the resistance is at the tip.

Aerials as a truss anchor frame vs a directional frame? Pat Rhodes’s & Tom Pendley’s theory vs Kelly Byrne’s theory? Risks of force amplification at the tip vs vs down the stick vs torque amplification at the fulcrum? Pros vs cons? You’ll have to decide & make an informed decision for yourself on how to deploy the aerial & employ your systems.

29 CFR 1910.180 (Crawler Locomotive & Truck Cranes)... [h.3.iii.v] prohibits moving a live load suspended on a rope system using the aerial itself (via rotating, raising/lowering, or extending/retracting).
