Weird looking. Why the huge tubular spacers?

I wonder if the longer hex parts are attached to the spreader plates, the hex is used to stop the spreaders turning as the nuts are tightened?

Seems perfectly correct to me. The lock nut is of a smaller thickness and on top of the main nut.

I wonder how far the anchor bolts went into the bridge ? Did the top bolts hit an impenetrable object that required an extra spacer under the nut? Looks like a good installation to me. Enough to take the top off a double decker bus!

If the bridge in the Google Earth picture is the same one as the one in Michael photograph then the bracket looks to have been modified or altered at some stage.

In Michael's picture there are 6 fixings to the masonry but there appears to be 8 in the second image.

Just curious.

If it'd been me, I'd've found it hard to walk away leaving that bottom right square washer – if that's what it is – visibly on the skew.

I suspect that is because the thin nut should go on first.

It looks as though the end of the thread has been hammered over to prevent removal.

One of my main gripes is studs that have a foot long of thread poking out the nut.

You see a lot of this in modern construction, an example of this is when stuck in traffic on a motorway with nothing to do and looking at the way the overhead gantries are secured to the concrete mounting blocks.

I haven't got a photo, other drivers stuck in the traffic alongside me might wonder what the hell I am I taking a photo of !

Are they not on the bridge wing, so they should be wingnuts?

Given the bullbar is made of half-inch steel plate and upwards, and truck bodies are a thin aluminium skin over a flimsy aluminium framework, take a guess.

The correct way to position lock nuts, according to MacGibbons Tech. Drawing for Marine Engineers published in the 1970s (in UK). And woe betide any candidate for his chief engineer's ticket who drew them in the reverse order. I know that forgetting to draw the split pin hole was grounds for a solid F. But nobody was ever known to draw the thick nut on top of the thin one. Unheard of at that time. This was an exam very strictly administered by the Department of Transport etc in the UK and former colonies for engineers responsible for the safety of ship worth millions and the lives of all aboard.
