Reefer: Recommend fixed spread or sliding closed tandems?

(g) Air suspension exhaust controls. The air suspension exhaust controls must not have the capability to exhaust air from the suspension system of one axle of a two-axle air suspension trailer unless the controls are either located on the trailer, or the power unit and trailer combination are not capable of traveling at a speed greater than 10 miles per hour while the air is exhausted from the suspension system. This paragraph shall not be construed to prohibit'
(g)(1) Devices that could exhaust air from both axle systems simultaneously; or
(g)(2) Lift axles on multi-axle units.

 

yes you can have 20k per axle. the author of this thread is wanting to know about loading 40k in the first 40 foot. on a 48 foot trailer with a spread with the rear axle all the way at the back, a 40 foot load would still be about 6 and a half feet from the center of the rear axle, putting the bulk of the load on the drives and basically making the back axle (and the spread for that matter) useless. as for a 12 foot spread, on a 53 foot trailer the front axle would still be back further that the front axle on a 48 foot trailer with a 10 foot spread. if you have never seen a 12 foot spread, you have never seen a real trailer.....................

 

yep, miss mine especially the ride..

agreed.....

 

G, I seen you in Wildwood some months ago but didnt look at your wagon close enough (you had your reefer not your flat) is that thing a 12 ft spread? I was pulling out as you were fueling.

 

that says nothing about the valves being controlled by electric switches in the cab..

 

G being me ?? If so, no my spread reefer went bye bye in the summer of 2001..

 

I meant greenpete, you snuck in a quick post there pounder...(grin)

 

raaaaaaaaaaaaaaaaaah jo !! just run'n up the ole post count friend...LOL

 

mitch, read it again. In so many words it means any device used to dump air from a single axle must be located on the trailer. If it say "on the trailer" it means just that, and not inside the cab. Trust me it a stupid rule since none of us drive down the road with an axle dumped. But they come in handy for tight turns.

 

For those of us that have never used a spread...when you dump the air, does that raise the axle or just take load weight off of it....hope you understand what I am asking....(obviously I don't...LOL)
