17,500 - 18,500. The ISX will weigh more the same rated at 450 horsepower at it would at 600 horsepower.. the displacement, block size, etc. are the same.
You'd be in the 18,000 lb. range.
15,000 to 18,000 lbs., depending on options.
Curb weight for a 780 is typically between 18,000 - 19,000 lbs.
~17,500 - 19,000 lbs, depending on specifics.
Somewhere in the vicinity of 17,000 - 18,000 lbs.
Assuming you're referring to a Volvo VNL 780 truck, with the double bunk sleeper, 12'6".
You'd have to contact Volvo customer service for this. IIRC, there were a couple different options for the 730 and 780.
To give an accurate answer, you have to give us an idea of how the truck is configured.. a 780 with standard 12k steer and 40k drive axles is going to differ greatly in weight than a heavy haul truck with, say, a 20k steer and 50k drive axles. The motor is going to affect weight, as well. The lightest motor will be the Volvo VE D 12, and the heaviest will be the Volvo VE D 16. In between those motors, there were several other motors available in various years - 12.7 litre 60 Series Detroit, Cummins M11, N14, and ISX, Caterpillar 3306, 3406, C12, C13, C15, and possibly the C16, etc...
That depends on if yours has the Cummins ISX, VED12, VED13, or VED16. I believe there was a VNL780 in production when the Detroit Diesel 60 Series and Caterpillar 3406E, C12, C13, and C15 were available options for Volvo, as well.
