FIVE Axle T660s, niche market opportunity

I gave up when he said 115000 lbs. Whats the point of buying a 5 axle tractor for 115000 lbs?

 

Agreed,.. it didnt take me long to figure out that I could avoid needing to drop the 2nd axle by throwing all the weight onto the trailer. I did my best to avoid it when ever I could.

I argued the need for a front flip to extend the neck. The neck already had the pins to set it up. His argument was that it would be over 80 ft and that would defeat what he was trying to do.

You guys can have all the heavy stuff.

im not really sure where you are comming from on this. i get more wiggle room on my 7 axle on bridge law loads than a 5 axle gets. the reason is because the sum of your axle groups is more than your outer bridge. so if you get 12 42 42.5= 96.5k but depending on your total length you may only be able to be say 92k meaning you have 4.5k lbs of wiggle room on your axle weights where a 5 axle 80k has to be right on the nose to the pound on every group to get there max gross of 80k.

but you hit right on that on bridge law loads at a certain point adding axles is not adding meaningful payload. the increase in weight per axle is less the more axles you ad each axle adds empty weight and at a certain point you just get so heavy empty its not worth it. then if you have to haul something down a weight restricted road you can't hardly load anything.

I don’t know what the say really - everyone wants to haul heavy but none wants to pay the entrance fee.

All I can say is good luck

 

Don't necessarily need to adjust the 5th wheel.

Taking pressure off the drops would make the steers heavier also.

It's possible the drops had too much pressure. Raising the front end.

I drove a truck with 9.500 on the steers. Raise the drop and steers had 11.500.

I adjusted the drop for 11.000 on the steers.

Oregon didn't like me driving around that light on steers.

It also gave me more wiggle room for load weight on drives

 

Unless you have some custom built trailers for extreme heavy haul, you'll never find a regular use for all five axles.

 

Except for 10 wheeled dump trucks. And some even have 6 axles. 2 drops and 1 swing drop behind the truck.

Dirt haulers and concrete haulers.

 

This dude has 7 axles

 

It's funny looking at them dump trucks with so many axles. Dump trucks and cement trucks run 4 axle trucks that are grossing 80,000lbs.. Most cement trucks are 2 steers axle and 2 drive axles and most 4 axle dump trucks are 1 steer, 1 steerable lift and 2 drives.

We gross out at 130,000lbs on 3 axle trucks and 4 axle trailers and even more on our 5 axle trailers. So only 7 and 8 axle setups.
