I saw a similar one a few years ago, it was in Bolivia and up in the mountains they wanted to build a road between two tin mines, it would have cost he company two million dollars to do it.......the indian capataz was able to push a bulldozer across the two mountains for $100,000..........I still don't know how the hell he did it.

In some parts of the world life is cheaper then giving the driver a life preserver.

A new standard for stupidity.
If he hadn't made it this would be true. Got to believe someone with some mathematical and civil engineering skills took a look at the bridge and decided that it would hold. Life is cheap but motor graders of that type are worth some money.

It was stupid even though he made it. What job on the other side was so important that he risked his life to get there? That bridge could have snapped at any point. He likely damaged it by that load. A return trip would be double risky.

If you are not risking something then what are you gambling with?

He almost certainly destroyed whatever integrity the bridge had. There is a bridge a stone's throw from my home that goes over the Little Manistee. It was a decent route to take to get where I was going until the local idiot with his skidder destroyed it by driving over it.. It was fine for autos, just not meant for anything else. Now the road is closed and the bridge rotting away.

Riddle me this since you are all wrapped up in enigmas:

WHY DID THE MOTOR GRADER CROSS THE STREAM?

To get to the side with the gas tank.

That suspension bridge didn't appear to have any trouble at all supporting the weight of the grader.

A grader like that weighs about 30 to 40 thousand pounds. Breaking strength of 5/8" steel cable is 65,000 pounds. I don't know what size cable they had or how many. The weakness of cable is that the inner core rusts if not properly lubricated.
When the grader crossed the bridge, those concrete bulkheads were pulling towards each other. They probably drilled and pinned the ground before they poured them. None of this matters if you have enough faith in Allah.

Yup. And that cable isn't being pulled straight up and down, where it has it's maximum strength either. People don't realize, wire rope is a machine. To work right it needs to be used correctly. Maybe they used 1 inch wire rope...

I've watched this video several times and shake my head. I don't know how that guy made it across. Allah. Or maybe a good Guardian Angel.

That bridge was built strong, the concrete anchors for the size and span of the bridge are huge. The cables are not punk ether at least 1" or a tad better. Bunch of suspension cables and I would bet other than the actual roadway everything was steel. Then there were the long wood planks that are for driving on would tend to spread some of the weight. The concrete anchors and their size compared to the span sorta tell the story, that bridge was built to carry a very good load.

Horder I agree they probably also drove pins then pored the concrete, the weight of the concrete alone is not punk on ether side, lot's of weight in the based, can not see how far back the bottom of the bases were dug back, looking it looks like the bases would fall back or were weighted on the back side, to resist being pulled together by a weight in the center of the span.

Edited: after a rethink.

But still looking at it is a butt clincher.

Dogman, those cables are not suspension and carrying that load at angles much less than they are rated for.

Granted, I know nothing about simple bridge construction. But I do know that I work with 7/8 inch wire rope on a winch. The winch is rated for 50,000 lbs of pull. I've seen this winch part that wire rope, like it was nothing.

This is wire that is lead correctly, to maximize it's strength. Looking at that bridge, I just see the wire rope they must be using is functional at maybe 25% of it's rated breaking strength.

I would think at the ends of the cables the load is a straight pull right at the anchors. Sorta the same as the golden gate bridge, look at the weight that the 2 main cables are carrying, but the load is almost a straight pull at the anchors at ether end of the bridge. Look at all the crap they hang off those two main cables, huge loads/weight.

Same, same, but at a smaller scale.
