OT goldhofer heavy haul trailer

That trailer might have cost as much as the transformer.

D9gdon,
Not really sure about the cost of either, I am just the guy who hangs wire on the transformer.

But both are spendy, for sure. Goldhofer is apparently a modular rig, this particular setup was 3 sections pinned together end to end. The first unit has a diesel engine, and drives, this rig is not drawn by a truck tractor but is self propelled. Control is via a wireless remote, so the operator can walk around and check clearances. Each set of wheels can steer, like a caster, and there are 4 sets of dual wheels, (each set of duals casters independently) wide at each "axle" location. The unit has a bunch of steering modes, crab, front/rear steer, etc. And each set of dual wheels had a sort of trailing arm suspension, so walking up onto and off of crane mats in a couple soft spots was no problem.

I cant recall the name of the rigging company unfortunately, but they were pros, the field engineer told us they move over 100 transformers a year.

Thanks,

Stewart

very similar setup to a 300 ton transformer taken over a 40 ton drawbridge we had. took me weeks to analyze each wheel load as it moved across the bridge

That is Edwards rigging, I work full time for bay crane in New Jersey we also own goldhofers, self propelled, tow behind, and dual lane (double wide) tow behind and we also own this 400ton capacity suspension beam trailer, this was a picture of us on Maryland the front trailer was 15 axle lines of goldhofer with the beam on top and another 15 axle lines for the rear

Are the axles always powered or are they pushed and pulled on long straight hwy moves?

And when you're negotiating a corner like that, how are the relative speeds of the two trailers synchronized so that one's not over- or under-pushing?
