Questions about pusher axles

Does the lift axle have a regulator valve? If not does it have a proportioning valve ( if it were running a California inspection report to allow it into California as a 4 axle)?



It would look like this….

 

I can't answer your question regarding other states. Wyoming always weighs ours separately as well as they only allow 55K on a set of tandems - 65K on a tridem on permits without having to call Cheyenne, so they check to make sure we are not over the 55k on the drives.

We are not tied into the driver suspension (would be pretty tough as it is non-air ride walking beam), so we have a regulator outside the cab to regulate pressure. We do have a switch with which to lift the axle in the cab, and it automatically lifts when in reverse.

 

Does California still say no to running a regulator?

 

Of course they say no

and they also don’t like single tire pusher axles

 

if you have a proportioning valve - you dial it up same as with a regulator vis the set screw on the bottom.

if not - I would in bypass the non existent regulator

IL does about weigh the drive axles and a lot of states want you in the +- 10% range across the 3 axles

OK wrote me my one and only overweight ticket for just that kind of issue / not enough weight on the pusher but under the axle group weight limit.

 

Does that go for the 20k+ steerables too running floats?

 

I've found,,"pusher axles" don't push anything. Sorry, can't help, but I'm sure they'd call in reinforcements to help find a violation. I hope you are getting filthy rich hauling this stuff, always seemed like a giant PITA to me.

 

Yes

to get full purple bonus weight - dual tires

they will give some weight on a single but it must be at least a 445

I have not spent a lot of time figuring it out as it does not apply for me
