Hello,
Life in the gig world has just been really good the past year or so, I need to be brought back down a peg:
I've thought on and off for a year about getting two reasonably-priced electric winches and attaching them to a truss for flying. I do a few venues regularly and to get the front truss up I've been using two Applied lifts temporarily and then dead-hanging the truss. It works, but really slows down the process because we have to set the lifts, build the front truss, hang it, and break the lifts back down before we can build the back truss. Likewise at the end of the show the front truss can't get to work until the entire stage is pretty much out.
I'm thinking a pair of $100 to $150 electric winches like these:

I would estimate total weight of the truss around 150lbs. So even at 440lbs capacity it's rated at 4 times the load. And they're 1200 watts at 120v, so it'd be easy to build a pickle-extender and run them from the ground. But I'd imagine these are stamped "not for overhead lifting" and language like that... at least they're UL listed, if in fact that's worth anything in this case. (They won't start on fire at least?)
So my question really is less about logistics and more about "is this just a really bad idea?" I always use two safeties (redundant hanging methods) and still get nervous flying anything, which is partly why I haven't already tried this. I could (and probably would) still dead-hang these once in the "up" position and take the weight off the winches. But how does flying things above crowds affect liability insurance... is that something I need to have actually noted? Or will they refuse to cover it? And is this the kind of thing where insurance won't cover anything without a licensed rigger? Maybe that's what this thread should have been about anyway... general questions for the future, at least I'm not doing this yet.
... and is there a good agent for gig liability insurance? My current agent is clueless and I think I'm not well protected.
