I am trying to put up an electric between two towers 27' apart. I need to hang it 6' above the towers and am looking for advice on the best way to go about it. The towers have metal flanges around them, much like I-beam, so I was thinking of attaching 6' long 2" pipes with beam clamps to the towers and clamping 30' of 12" box truss to the pipes. I need to hang 8-10 instruments, probably 2 tree packs, and about 100' of cable from the truss. There is absolutely nowhere in between to support the truss from. I am concerned about the beam clamps holding the pipes securely and wether pipe is the best way to raise the truss the 6' I need it to go. I would appreciate any advice and all suggestions.
