One Heckuva Crane!

[Diggin It]

I was looking for something entirely different and stumbled on this picture:

New $1 million Doty Bridge project on Coalwood Grade completed in Alger County

The new 130-foot bridge over the North Branch of Stutts Creek replaces a temporary bridge in place since 2000 over a former railroad trestle.

Cranes are amazing. During our shutdowns/rebuilds I have seen 600 ton crawler cranes and one worked at our mill for a month with a million pounds of counter weight. Watching them work was amazing but seeing them transported in in pieces and assembled was even more amazing to me.

The Liebherr documentary on YT is amazing. I suggest you watch it.

Which cost more, the bridge, or the bridge placement?

Prep needed to tear down transport and setup again must be mine boggling at times.

I had a 300 ton crane for lifting a tilt up at one of my high school gymnasiums. It required 17 semi loads to deliver to the site and 2 smaller cranes and 5 days to assemble. Same to disassemble and transport off.

How long ago was that?
300 ton crane to set bridge beam last year self assembled. Hydraulic crane, lots of semi loads for counterweights
passed a 500 ton crane on highway today. Travels without its boom or any counterweights

About 15 years ago. The big issue was about 250’ of stick.

They used one like the one on the right side of the picture a couple of years ago when they set the prefab concrete bridge beams for the overpass on the new bypass in Goshen. The beams were 165 feet long and weighed about 114 tons. The crane had the same wings on the boom and was a 250 ton Liebherr. There was a Grove that handled one end of the beams and the Liebherr handled the other end.

I like the Liebherr video of a crane picking up a crane, picking up a crane, picking up a crane, about 5 cranes. Thats a lot of engineering.
