10,000 and up, depending on what type of trailer it is (e.g., dry van, refrigerated van, flatbed, stepdeck, RGN lowboy, beam trailer, etc) and what material it's made from.
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.
16,000 - 20,000 lbs usually for the front part ("truck", "tractor", "cab"). But the empty trailer adds several tons more. For example a 53 foot long simple box ("van") trailer weighs 10,000-15,000 with nothing in it. So a whole 65 foot long empty system (truck and trailer) weighs over 30,000 lbs. Shorter box, flatbed, and covered wagons systems would weigh less. Systems with an extra long truck or specialized systems, like some of those with tank and pumping equipment, may weigh more. Adding to this answer. I have a 2003 kenworth w900 with a stepdeck trailer and i weigh 32,000 empty.
The total square footage inside a 53 foot semi trailer is about 3,400 square feet. This space can only be fully occupied if the semi truck and trailer weight combined is 80,000 pounds or less. Federal law regulates how much a loaded semi truck and trailer can weigh. There are also limits on axle weight to arrive at this total. It is 12,000 for steer tires, 34,000 for drives, and 34,000 for tandem axles.
Semi-trailers come in different sizes and not all are made with the same materials and components or extra features. A 53-foot empty semi-trailer can weigh anywhere from 10,000 to 25,000 pounds.
1375
15 tons
truck and trailer 35000 pounds.
Empty around 35,000 lbs
14,000 lbs
Empty, anywhere between 30,000 - 35,000.
Depends on size of truck and trailer, size of fuel tanks. But a good guest would be about 35,000 lbs.
69,500 pounds
