Sliding spread axles?

Canada,California.............a lot off places penalise you for having a to long kingpin to axle ratio or having axles too far spread out.

 

or you have a light load. if you only have 15k lb load slide your spread closed you get less tire scrub and still can carry the weight

 

there are 13 states if i remember right, that have kingpin laws. on the west, california is the only state. on the east, a majority of loads run through tennessee. then you've got florida, i think both virginias and one of the carolinas. new york and every state northeast. michigan, wisconsin, and minnesator, i think.

don't have my list handy. so i could be wrong on a couple of states.

your fine with a 48, but not a 53.

 

I tried to design a way how to slide spread-axels, but I realized it would be stupid unless you had extra valves to open and close the air to the appropriate axle, it could be done, but it would be very expensive

my other plan involved motors that ran off of reefer fuel, but that's even stupider more weight and more money spent

 

There are actually a lot of spread axles that slide. People do it for CA bridge law or to run Canada. It's just like sliding a tandem.

 

does each axle slide individually? that's what I meant

my system involved sliding each axle back and/or forth

 

no the last axle is hte one that slides front or back. the inner axle(closest to landing gear) stays stationary

 

cool!

yea, in my system they both slid


how do you slide it? is it the same way you slide regular axles?

 

going to assume yes. i dont have that option. and having bot axles slide is stupid. have the inner axle lift so you dont have to drag it when empty( or light)
