Another bridge knocked down.

[grsthegreat]

Someone's assuming the driver was at error, but we don't know that for sure. A number of years ago, I checked the sign posting the clearance on a McDonald's underground parking and drove in. Within seconds there was a whole lot of noise when the ladder on my truck's roof ripped through about sixty feet of aluminum soffit material before I realized what was happening and stopped. This was witnessed by a cop. "Just the person I need", I told him. He noted the clearance was posted as 7' 6" when it was actually measured at 6' 7". McDonald's gave me a wad of vouchers in consideration of the paint scratches on the roof of my beater truck.

Thats what happens when a dyslexias reads a tape measure hehe

Hit it at about 50 mph.

From:
Traffic now moving at overpass

"Const. Inman said the driver of the transport, who thought he had clearance, was travelling 80 kilometres per hour at the time of the crash. "

Famous words spoken..... to the DOT officer I'm sure.

Bridges, for the most part sit on trunions so thay can move, expand and contract, without buckling.

This one moved a lot......:laughing:

So what happens in an earthquake where there is uplifting? do the bridges just fall apart?

The two ways they do it here is by using large plates to clamp the I-Beams allowing for some expansion and contraction length wise.

The other was is with cables... lots of them... everything can move but not far enough to separate.

I told you to deflate the ties not inflate them!!!

Can anybody tell what size excavator it is? A 30 metric ton machine would weigh in the 75,000 pound range.

The pic I seen showed it was a JD 240. A salesman once told me that the first two digits tell the metric weight of a JD... so.... about 24 metric ton. Now a Cat 325 trackhoe would be the last two digits, so... 25 metric ton.


I've never seen a large trackhoe being transported with the boom to the front which leads me to believe Whom ever loaded and tied it down (probably the driver) had no clue to what they were doing.

Here is one for you:
Policeman: "It looks like you got stuck there."
Driver: "That is total nonsense. I am carrying that bridge and I just run out of fuel."

:laughing::laughing::laughing:

That one looks like an easier fix though. Just let some air out of the tires:thumbsup:

The cables are what you see now all over California bridges. And the plates on top of the beam flanges with oversized holes and a greased plate underneath is what I had to do when I put in my bridge. About 3 miles from 1989 Loma Prieta 6.9 epicenter.

I guess I don't get it but why didn't the truck seperate from the trailer. I would think that the pin would be the weak link in all the other mass being moved in this wreck.
