It can be done safely. Just too many times it hasn't been for me. Think of all the safe MAX 737 flights.
I haven't worked on the problem, but I am sure there are safer solutions that fail less, and I'm sure they cost more, probably a lot more.
Currently working on a school. "Yes, I absolutely need your AV subs submittal. I need to know how much their video wall weighs so I can order counterweight for itIts also weird that it came down flat like that. I'm suprised it didn't buckle more.
Its also amazing to me how many people are carrying video walls out there that have no idea how to rig or the dynamic forces walls can exert. I had a show come in a year or two ago that wanted to hang a wall on house pipe.... dumb.... add to that we are double purchase. Promoter got to pay for local truss and motor for that day.
My arms beg to differ after hanging any significant number of aluminum framed double panels (biggest so far is to 8 m x 4 m/~26 ft x 13 ft, did that one solo, yay arm day!) (Side note, an alum. framed 8x4m wall weighs just over an imperial ton/under a metric ton.)"Videowall doesn't weigh anything"...
