Re: Line Array Carts
I am ever the contrarian. Let me make a couple of points:
1 - Any thing getting flown overhead needs every attachment point inspected for tolerance every time.
2 - If trucking stresses may de-range ("oval") attachment holes or score some pins, they are quite underdesigned and should not be rigged overhead anyway.
3 - Educate yourself on basic material science and mechanical engineering i.e. mild steel v. 6061 aluminum, "double shear", etc.
4 - Buy replacement hardware from reputable sources.
I have seen many LA carts come out of various USA soundhouses with years of rigging experience. Most are smartly executed and operate as the time & labor savers they were designed to be. I worry more about the fatigued old points in many buildings more than the fresh, low-cycle hardware being attached.
Build and enjoy your carts!
