Heavy spec truck purpose?

I have same heavy specs pulling super-b trains. 140,000 lbs gross, if I stayed on dry pavement I maybe able to get by, but I load out in farmers fields and it takes a lot of torque to get that much weight rolling on soft soil.
My last truck only had 40,000 lb rears and after two years it blew out all the bearings in the front diff. Plus the lighter rears would push 300 degrees climbing the mountains, 46k's stay much cooler.

 

I use those kind of specs with a 3 axle trailer on these loads every day.....

 

550hp C15 cat, 14,000 front, 46000 rears, 4:56 ratio 18speed duel over drive tranny, pulling super b fuel tanks, 140,000lbs through the mountains of BC.

The short wheel base 244" is for maneuvering. Deliver to some tight spots KW T800.

 

That and traction on a tridrive is far superior to a tandem. All 3 diffs and inter axle locked in you can power through just about anything without chains.

 

I learned real quick driving a tri drive winch tractor moving rigs that if I chained up all six and locked everything in I could go farther in the mud than anything else could come get me when I got stuck.

 

4:56 gears? Holy crap you must have to do 90 everywhere lol

 

Last time I ever listened to a consultant.....




D8 pulled me out lol

 

No. 100kph 1500 110kph 1600 120kph1700. Never push her over 1700 rpm.

Best part is I climb ####### in sixth. Never drop out of high range. Burnaby to Prince Rupert!!
