Truck trailer axle loads permitted
Truck trailer axle loads permitted
(OP)
Hello Guys,
Im studying max. axle load for trailers in the us compared to their european counterparts.
As far as i can see the normal max axle load for a single is 20K and for tandem is 34K.
Why then does for instance Hendrikson offer (single) axles >20K?
Why would they offer these when they are basically not allowed?
Or are these allowed with special state specific permits?
Also on interstate highways in that case?
Thanks and have a nice one

RE: Truck trailer axle loads permitted
Some trailers have two axles in a spread axle arrangement rather than tandem.

But even then 40K is max for a tandem according the bridge laws, right?

Try looking at this:

Yeah now i see that in spread the total axle loading for 2 or more axles can go over 40k (at least in CA i guess)
But kind of weird since i thought that generaly 20k(single) and 34k(tandem) were allowed without permits on US highways.
But CA seems to have strikter limits for semi-trailers? 18k(single) and maybe less than 34k(tandem)
