Another bridge knocked down.

It looks like someone forgot to bolt down the bridge in the first place :laughing:

That's what I was wondering. It would be interesting to know how or if the bridge was secured. Still blows my mind.....

IMO there's no way those beams could of been bolted down.

But it is still something how that boom was able to move that much weight, with out being more damaged. Good advertisement for JD

Looks like continuous welded rail, the only thing still holding.

Believe it or not, bridges aren't really bolted down, mostly just gravity hold them in place, or not in this case.

I think a little heat on the boom of that JD will straighten it out and let it go back to work.

Seeing is believing and eyes don't deceive. Simply bewildering to believe that the boom held up. Another reader inquired about the traveling speed of the truck, and I wish to reiterate that question. Has anyone found out the answer? I tend to believe that the truck was probably approaching at a slower than normal rate of speed, because of the driver's concern over the clearance issue.??

Hello. . . Allstate? I have a little bridge work needed and I ain't talkin' a trip to the dentist here.:laughing:

 

[dodge man]

He may have been going full speed, you never know. He may have also realized at the last second there might be a problem and slowed down. Someone near here hit a bridge with a Cat D8 on a lowboy going full speed. It was a concrete bridge and it didn't give as much. I'll never forget the gouges in the pavement from where the D8 came off the lowboy and flipped down the road.

Yeah, imagine the call to the boss Better not hold the phone to close to your ear :laughing:

As far as speed goes, it had to be fast enough to move that much weight, but not so fast that it would rip the boom right off.

Just guessing between 30 and 40 MPH???

I was talking to an old timer in the construction field about this, he said bridge sections are not fastened rigid, to allow for movement, but should still be secured enough to prevent that from happening.

I've seen a few times where trucks, cranes etc hit bridges and nothing like this. One old train bridge in the next town was low enough that it was hit so many times over the years, the beam edge was bent up like a potato chip.
In one incident it was hit with a mini excavator and the driver abandoned the trailer and machine, they found out later it was stolen.

That bridge has since been replaced.

Tsk! Tsk! Such a sad commentary on the state of America's infrastructure. A shame non of our politicians had visited that bridge before so that it would have at least been repainted.



Good build quality on that excavator though, not to mention the chains! :thumbsup:
