My guess is that they tried to fix a sagging beam with it by putting tension on the cable and the plate with the angle was under the beam. tightening the cable would put upward pressure on the center of the beam but with the low angle there would have to be many times more tension in the cable that the upward force it would provide.

If they have installed posts, I would say the cable is moot any more.

Heavy...if it was common you probably would have seen it before.

In a residential basement. It goes from one end of the beam to about two thirds down.
The homeowner has since installed new support posts.
Was this some way of supporting the post through upward tension? Have not seen this before.

Interesting approach for taking the sag out of a beam. Probably wasn't very effective.
Never seen a electrical panel installed horizontally.

To get lift you would have to have a much more significant angle and a much larger offset undee the beam. It the angle block at the center were 3' tall you could get some lift but not at 3"

Not sure exactly what I am looking at from camera angles. If there is a support in middle between cable and beam wouldn't it be a king post truss? I have seen this on bridges. Recently repaired roof system made with king post trusses. Note that fasteners are heavily loaded when there is small angle between beam and tension member.

I work at a house that has 2 of those on steel beams in the garage , 24' or so span. There is a piece of 6" sq tube welded to the middle of the beams and the cables go under them. No posts at all in the garage

I don't think you have seen many electrical panels.
