Holy crap.. I wonder if the rig in the rear is there to help out on the hills. They were linked together.

Mowin, that rear 'tractor' is there to help provide power (for any hills especially, but also for getting & keeping things moving on the flat) and also to provide steering for the tail end of the load platform which is hanging between the pulled/towed pushed/driven multi-articulated trailers at each end. So there's load carrying ability and articulation in a whole heap of places through-out the entire rig, just not immediately under the load platform!! :shocked:

That whole rig is very similar to those pioneered here on the Snowy Mountains Hydro-Electric Scheme, altho our steep & narrow mountain roads & the need to move 200 ton rotors etc often called for the running of TWO multi-wheel-drive tractor units connected to those 3xtriple bogie articulated 'load platform' trailers at each end, with the actual load then slung between the trailers! And SMHEA didn't have ANY 'slave facilities' or electronic rev or speed matching devices to synchronise the driving when they did it, so each tractor driver had to manually drive their particular power unit to within a bees' mickey whisker's tolerance of all the others!! :yikes:

But it's bloody amazing the sheer size of some of the gear they actually move around these days, isn't it!!

Standard 19 axle tractor trailer, in the heavy haul business, fairly common.

The company I worked for had a few, and they were in constant use. The pusher in the back was unpleasant duty, the tires in front tossed up rocks and stones, busting windshields and radiators, and scaring the hell out of the driver. Note in the back of pusher, a large block of concrete, usually 15 or 20 thousand pounds, to put some weight on the drive tires. Also note on the back of the trailer a large hydraulic pump to operate the steering on the back axles.

This load was going through Pennsylvania, and required two private escort cars, and two State Police escorts. Permits for these loads could take months to acquire requiring road surveys. If the load was heavy enough the Police would stop traffic so only the truck would be on a bridge.

Toll booth costs ?

 

[Bob Denman]

:shocked: That thing is big enough to have it's own Zip-Code... nojoke

 

[gkamer]

Yup

Holy crap.. I wonder if the rig in the rear is there to help out on the hills. They were linked together.

That would be my guess, to either push on the up side and pull on the down side.

Thanks for the info.:thumbup: I figured it helped push, but didn't think of the turning issues.

Very interesting. Biggest rig I have seen so far. :bowdown::bowdown:
