Whats best truck set up to haul GCW 140K?

Tuned 550 putting 600/2350 plus to the ground

11 5/8ths x3/8 is the biggest single frame kw has.....rmb 2,572,000

I believe the 1/2 inch thick frame is only 10 something tall and is rated for less strength.....but I could be wrong....

 

I had heard if you order over 300" wb they always want to double or put a insert in. You know bout that @Cat sdp?

 

Not sure of the exact length , but yes that long they want/demand a insert or full double....

 

I went and measured mine. They are 12 1/2 X 1/2". I was told kenworth was offering that now. That is second knowledge but it's from a good source. Of course he's not looking for 300+ inches

 

I will add also IHC only offers it in the HX or older 5900. Anything else you can't get factory heavy haul specs.

 

Mr Steve with a heavy haul.....

 

I’m a little late to the party here but when he said “3/4 insert” I believe that’s 3/4 of the frame length. I’m planning on specing our new one with the large single frame. My current one is double from the steering box to the rear of the bogie, I’m getting some rust jacking now.

 

Yes...3/4 is slang for the total length

 

I’m curious if after running the truck for a while if you feel the 22/20,000 front is worth the extra weight and reduced turning radius? Can you actually get 20,000 up there? My experience is most can’t and just seems like something people do because they think they’ll “need” it. I know I HATE my 20,000 front and it’s a 4 axle.

 

I can get 20 up there. Don't do it very often but I routinely have 15-16K up front.

With our 3 axle Reitnour flat I can get the 20/46 on the tractor but I have to remove my rear fenders to clear the frame of the trailer. With most legal loads I run about 14.5-14.8 up front. Can't get much more that with a standard step/rgn with a 10ft upper deck.

My jeep has enough swing clearance as well to run 20/40/60 or 20/46/60 if I want. When I stack up I usually try to slam the fifth wheel as far up as I can to keep my overall length down so I usually end up about 16.5-17K on the front and 26-27K on the drives.

Our 4 axle truck is a Pete 378 with a 14.5K steer and 54" drive/pusher spacings. He's about 1-1.5K heavier than I am and can only haul about 6-7K more. With the amount of legal weight flatbed stuff we do that extra weight makes it very difficult to book him return loads. He can only scale about 42-43K on our lightest flatbed.

I could probably get away with running 385s on the front because I rarely actually hit 20K but sometimes I do and I'm just not a fan of running things right at the ratings especially tires.

I've had the truck loaded to 20/65/75 on 6 axles once. Customer had a broken crane and needed a 117K piece moved to a different part of their building. Couldn't get the big trailer into the bay they needed it out of so I had to do it with our 3 axle flat. Creaked and groaned the whole way. The way the saddles for it had to sit the weigh was only spread across about 15ft of deck.
