SAN FRANCISCO AT IT'S FINEST
 

THERE ARE ALOT OF TIMES I WISH THERE WAS MORE SPACE BETWEEN ME AND THIS CITY, BUT THIS WAS A GOOD JOB. THE CITY OF SAN FRANCISCO REQUIRED C.C.MYERS TO BUILD A BRIDGE OVER A PET CEMETARY, IN ORDER TO BUILD THEIR FALSE WORK ON FOR THE WORK THEY WERE DOING TO THE ROADWAY ABOVE IT. THEY WERE ADDING AND BUILDING LANES TO THE EXISTING ROAD WAY ABOVE. IT IS AN OFF RAMP FROM THE GOLDEN GATE BRIDGE TO THE PRESIDIO. THEY SPENT $1 MILLION FOR THIS BRIDGE OVER A "PET CEMETARY". WE HAULED 10 OF THESE GIRDERS FROM LATHROP, CA. TO SAN FRANCISCO, CA. THEY WEIGHED IN AT 160,000 LBS AND THEY WERE 130' LONG X 8' HIGH. WHEN THEY ARE DONE WITH THE PROJECT ABOVE THEY WILL DEMO THESE GIRDERS WE HAULED IN. DON'T GET ME WRONG, WE'LL TAKE THE WORK WHEN EVER IT COMES OUR WAY BUT IT SEEMED A LITTLE RIDICULOUS...THEN AGAIN IT IS SAN FRANCISCO.

very cool truck man

Re: SAN FRANCISCO AT IT'S FINEST
 

I've been planning on building a setup like this some day . We got a co. In my back yard that builds girders like this and the I beam 1s . maybe you herd of them ( use to be Schuylkill Products but another co. bought them after they got caught doing some BS )

And they wonder why some of these cities run out of money to fix things that really matter.:confused:

Re: SAN FRANCISCO AT IT'S FINEST
 

Reeve. Can you give a short explanation of how the steering works on the rear carrier. I don't see a cab, so how's it done.
Thanks Rob

Re: SAN FRANCISCO AT IT'S FINEST
 

It is the last 2 axles on the dolly that do all the steering. The bullster on the dolly has a very heavy duty arm that connects it to the rear 2 axles. They are on a pivoting point. Every time you make a turn with the truck and the bullster turns it, the rear axles follow. It cuts the tracking of the trailer way down and you can make alot tighter corners. When you need to make even tighter turns, there is a pin in the arm that connects the bullster to the rear 2 axles and when you remove it, you can self steer hydraulically the rear 2 axles. When you take that pin out, you start a pony motor that runs the hydraulics that are run off a lever that has a neutral valve for when it is not in use. There is a platform you can sand on on one side of the dolly and run this lever or you can plug in a remote that is on a cord and actually walk along with the trailer and steer it. The cord is about 20' long. They've probably come out with cordless by now though...lol. Any how, it is kind of hard to explain in text form. If your still up in the air on it but interested further I can take send pictures that will give you a better idea of how it works. Let me know

Re: SAN FRANCISCO AT IT'S FINEST
 

Now this is something that's been on my mind for ages and been thinking about using a couple of Bruder trailers and chopping them up:D:D keep the photo's coming the work you do I love it :D

Cheers Tracy

Thank you for the complements!

Re: SAN FRANCISCO AT IT'S FINEST
 

I think I've got it. The load mount is a giant pivot point with a drag link mounted on the bottom. The bullster runs from that drag link to a drag link mounted on the top pivot of the rear two steering axles. The bullster must also be crossed for it to steer properly. The steering axles have to move opposite the load. Steering is almost like a giant fork lift from the back of the dolly. The hydraulics are just used for close maneuvering at the job site or tight corners. Am I close with this. Also what kind of speeds can you run with this setup.

great pics..

Re: SAN FRANCISCO AT IT'S FINEST
 

Pretty much got it. As far as speeds you can travel, it all depends on what you're hauling. The trailer is capable of all of the posted speed limits. Usually weight keeps you from getting there though...lol
