Ladder crane. I admit I'm skeptical.

Even on the ground, tilting the ladder like that, to kinda form half a gantry; is that OK? 2:31 video:

On the step ladder video, he isn't lifting much weight. Doesn't seem worth the trouble but do suspect it is safe. The other two seem foolish.

I agree, re the step ladder. The motor and pump might be 60-80 pounds, though I question such a quick convenient hook attachment. It seems reasonable extracting the unit from inside well of a condenser, not too different than an engine crane.

Though pertaining 1st two video's
Even if those aluminum extension ladders are rated IA [300 lbs] a load on convex side is questionable, not to mention what looks like a single basket sling. A/C units, weight-wise, aren't very symmetrical.

I think the concept is brilliant but could certainly lead to accidents. I have a 36' ladder that weighs over 200 lbs, haven't moved it since I bought it but it is certainly strong enough.
