We have 4 1/c #750 that need to be pulled out of 3 manholes . The run is about 2000’ that goes through the manholes. The area is wide open. How would one approach pulling these out and how? Cut at each manhole and pull from there? What would you use ? Truck? Thanks

Check with Greenlee or similar. They have data on pull force required and you can rent pullers. The issue that you may run into is that depending on if water is involved and it gets sanded in which is common in coastal areas you might never get it out and just tear it in half. Then you are looking at excavating or directional drilling and pulling new. Always discuss the possibility with the customer ahead of time so they aren’t surprised if you go from a couple thousand for the job to tens of thousands. It is best to bid these as excavation then maybe you get lucky.

Use pulleys to avoid side loading on the duct.

A truck is limited by the engine and weight. It’s ok for a couple poles but that’s it.

Vaults are like overhead lines. Not a place for the inexperienced. Sub Ir out.
 
Cut it in the manholes.

Install a curb roller on the edge of the manhole.

Hook a truck to it and pull it out.

Cut it down into manageable pieces, usually 20 foot chunks or less.

Scrap it out.

Done.
 
You want some roller set up so the pull is straight out of the conduit and then over the lip of the manhole. I would use a setscrew eye on the end of each 750, and then to a pulling rope, you may not have enough length to get a wire basket on the wire.
I would pull out one and see how it goes
Buy a battery cutter (Milwaukee has some nice ones) and cut into lengths to scrap. Your scrap cost should pay for all your tooling.
Spend some time in the Greenlee catalog, maybe give them a call.
Once you get set up and get one out, the rest should be easier
