Depends on size of truck and trailer, size of fuel tanks. But a good guest would be about 35,000 lbs.
truck and trailer 35000 pounds.
Empty, anywhere between 30,000 - 35,000.
There is no minimum weight.
Most trailers are semi trailers. You're probably asking the difference between a semi trailer and a full trailer. A semi trailer is not wholly self supporting, and weight is distributed both the trailer axles, and to the tow vehicle. A full trailer supports its own weight fully.
The weight capacity for semi trailer is 80,000 LBS. That is calculating with two or more consecutive axles to the nearest 500 LBS.
That depends on the size of the trailor.
The "tractor" is the vehicle which actually powers the combination. A semi-trailer is any trailer in which the weight of the trailer (and the payload) is shared between the trailer's axles and the axles of either a dolly or the towing unit (in contrast, a full trailer supports all of its own weight).
The weight of the truck/truck trailer when it is unladen (empty) .
6500lbs
13,000 lbs
the weight a semi can haul depends on the empty weight of the semi subtract the empty weight from 80thousand pounds. eg ; 80.000 minus empty weight 21.000 equals 59.000 pounds in this instance the cargo that could be legally hauled is 59000 pounds total semi weight which includes all tarps, straps ,equipment and load equal 80.000 pounds
This varies greatly depending on the type of truck. For example, a sleeper tractor weighs more than a day cab, a refrigerated van trailer weighs significantly more than a flatbed trailer, and so on. I drive a tandem axle day cab Sterling semi (this is a semi tractor with a total of 3 axles and no sleeper), and I pull a 53-foot dry van trailer (this is a box trailer without a refrigeration unit). When I have run it across a scale empty with about 120 gallons of fuel (this will also change weight as fuel weighs about 12 pounds per gallon), the whole truck weighs very close to 29,600 pounds. An empty semi can weigh as much as about 40,000 pounds, leaving room for 40,000 more of cargo before reaching maximum legal weight of 80,000.
