20,000 lbs. statutory for each trailer axle, provided that there is a 10' spread between the axles. This does not affect the gross weight you are allowed.
A ten foot spread axle trailer is allowed 20,000 lbs. per axle, for a total of 40,000 lbs.
Front axle 12,000, Front tandem 34,000, Rear tandem 34,000 unless it is a spread axle trailer; then it is 40,000 for the two rear axles combined. Total weight not to exceed 80,000 lbs.
With a ten foot spread, you can have up to 40,000 lbs. total on the trailer axles, but no more than 20,000 lbs on each individual axle.
That depends on the axle configuration. If it a closed tandem typically 17,000. If it is a spread axle 20,000. If it is a single axle (Front of a Semi) typically 12,000. Those would be the "legal weights", but states allow different amounts of weights with a permit for over weight. That all depends on the state. Wisconsin will allow 23,000 per axle.
It can vary according to the configuration of the trailer axles. A straightforward tanndem, with no spread, is permitted 34.000 lbs. on the trailer axles, which would allow the combination to gross out at 66,000 lbs. A 10 ft. spread axle, on the other hand, is allowed to weigh 40,000 on the trailer axles, which would permit the combination to gross 72,000 lbs.
Well, you're limited to 20,000 on the single axle. If you have at least a 35 ft. bridge to the trailer tandems, you can gross 34,000 on the trailer tandems (or 40,000 if you have a 10 ft. spread between the axles). As a rule of thumb, 12,000 is going to be your limit on the steers.
The same amount it could with tandem axles... you can put 40,000 lbs. on a 10' spread, but it doesn't increase the gross weight you're allowed.
Legal limits can vary from state to state, but a good general rule is 800 pounds per wheel. Axel weight limits should not exceed 73,280 pounds.
A trailer with 10' California spread can have 40,000 on the trailer axles without requiring a permit.
#1 axle is the steer axle, #2 axle is the front drive axle, #3 axle is the rear drive axle.
a " conventional " or " regular " axle - an axle that is not a limited slip axle
