Possibly... I just don't see it.Saw this . . Potential failure?
Sorry guys. I cannot upload the file.
Website issue?
Finally able to upload the image.
Potential failure? Sure, everything is. Whether or not this depends on multiple things but the first issue I have is that it violates one of the Primary Directives of Rigging - compression, not tension. The video wall should be rigged from the top truss chords, near a node point. More ideal would be a choke around the bottom chord, a wrap around the top chord, and then back through the middle of the truss to attach to the video wall bumper. From the number of wraps on the downstage chord it appears that the slings are of different lengths.
The other is that attachments should be metal to metal whenever possible. If these are "gak flex" (internal wire rope instead of polyester fibre), the slings meet that requirement.
Finally it appears that the video wall is attached directly to the roof structure, meaning the load is being raised with the roof. This is a serious violation of temporary demountable entertainment structure protocol.
The video wall supplier should supply appropriate chain hoists and rigging for their gear. This is a "fail" even if it was successfully lifted and didn't fall from the sky.
Am i getting this right, compression is better than tension?
