Large Pipe handling equipment

[andriver]

Gents,

I am working on a job where we are on an offshore jetty that we are installing pipe in. We have a 32" diameter pipe that is 35' long that we need to move from one side of the jetty to the other over a concrete roadway. My superintendent is looking for a pipe cradle cart, or something of the like with the capacity and size needed to move this pipe. Everything we have found off the shelf online has a maximum pipe cradle diameter of 28". I have been on countless web sites and cannot find anything bigger. Mobilizing heavy equipment will be costly due to having to get a barge crane.

He came to me to design him our own pipe cradle cart or to modify an existing cart. Before going down this road I wanted to know if there were any suggestions out there that are off the shelf. Just looking for a cart that could handle a 32" pipe, we could throw more than 2 3 or even 4 under the pipe if necessary so its not really a capacity issue so much as a dimensional issue. Any suppliers would be appreciated. We don't want a dolly that sits so low to the ground because the concrete roadway has a large slope which could cause the pipe to dig into the roadway.

Here is an example of what we are looking at:

Sometimes its possible to do all the right things and still get bad results

These guys aren't far off in size, Just adapt it a bit or get them to.

Or get some flat ones and bolt something like this to it - scroll down to the saddle shoe.

A picture or drawing will make this come to life.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Andriver:
Use your head, how are you actually going to do this? You have to actually think through the approx. steps of the process of moving the pipe, ten different ways, with slight variations in equipment. This starts eliminating or suggesting, and reinforce good points of various options. Then, you need to provide a great deal more design info. than you’ve provided for anyone to start offering ideas. A sketch of the cross section of the jetty, with good proportions, good notes and dimensions would be a good place to start. We can’t see what you’re looking at from here. What equipment do you have available? How much does the pipe weigh? You did say 32" dia. by 35' long, so .5" thick would be about 6100lbs. each, 1" thk. about 12k each. How many of these pipes, 1 or 100? How are you ever going to roll the pipe cradle carts you show over a jetty which likely has rock armor down at the water line, then up a hill, etc?

Can you roll this pipe without hurting it or its protective coatings and other hardware on the pipe? Maybe fasten a temp. collar on the pipe to protect it. Why not build two 6"x6" oak rails across the jetty. Crib as needed to match the terrain and rock armor, and the bending of the rails. These rails would be 6-8' from the end of the pipe and up the hill to the pavement edge. Then, you anchor one end of a rope at the road’s edge, on down the slope and around the pipe, and back up the slope. Do this near each oak rail and pull the pipe up the slope, with some good control using two ropes. Put a chock behind the pipe, lay the rail across the roadway to the rails on the other side and on down the hill, with a second set of ropes. This minimizes road closure times. If you can move the next pipe section 8 or 10' longitudinally, you only have to jump one 6x6 rail for the next move. One the third move you probably have to move both rails.

If you have a small dozer with a rear winch and a skid steer with a pipe lifting front end fixture, or some such..., you could winch/run the skid steel down the slope to pick the pipe up, then winch it back up the slope, cross the roadway, and repeat, in reverse.
