Yet another stage collapse 8/10/13

Re: Yet another stage collapse 8/10/13

Just another reason to use truss towers and guy lines( it looked like they used speaker hoists and no guylines in sight. It could just be bad angle from the video however.

I see what look like Genie construction lifts supporting downstage and upstage trusses, with a roof spanning between the trusses. I also see a scaffold tower with speakers on it still upright, despite minimal guying. I'd say this is yet another reason to use properly designed structures in accordance with the manufacturer's instructions (if a manufactured system) or in accordance with the design drawings (if an engineered structure). Just using truss towers and guy wires does not a safe system make.
