Concrete is measured in yards, not tons. As for permissible tonnage on a dump truck, it'll vary by state. IIRC, in North Carolina, a tri-axle dump is typically good for 16 - 18 tons, dependent on tare weight, wheelbase, and whether they're traveling on primary or secondary roads.
Dump trucks are used mostly to haul neighborhood trash to dump sites. Depending on if you need to haul things such as garden waste or scrap metal, it might not be necessary. Instead of getting a dump truck, you can rent a pickup truck and/or a trailer.
Dump
I use my truck to tow my camper and haul junk to the dump.
The main differences in the dump truck and standard truck is the size. The dump truck you will be able to haul more stuff and it will be easier to off load.
26000 lbs of cargo? A tandem straight truck, such as a flatbed or a dump, could haul that amount of weight legally.
Dump trucks are used in construction sites to haul large loads of materials to and from the construction site. Jobs available with dump trucks are usually to drive the truck.
The volume that a dump truck can hold depends on the size of the truck. You could say that there is no 'typical' dump truck. The horsepower, the axle weight, and the size of the box are a few of the features that determine how much the truck can hold and haul.
That depends on what type of dump truck, what type of commodity, how it is measured (by weight or by cubic yard), and the state laws regarding weight allowances. A Class 7 single axle dump truck can typically haul eight to ten cubic yards, or up to eight tons of payload. A tandem axle dump truck can typically haul 15 to 20 yards, and anywhere between 12 and 16 tons of payload, dependent on truck specifications and local laws.
If a dump truck is hauling 34 tons of stone that is 68000 pounds of stone. Tons is a just a short way of saying it.
A standard dump truck can haul approximately six cubic meters of sand. Sand and gravel are aggregates for foundations in Philippine construction.
Special tow trucks are called in to haul larger vehicles.
You'd have to give me some idea of what type of dump truck you had in mind. You could be talking about anything from something mounted on a one ton pickup chassis all the way up to an off-road dump truck rated to haul over 400 tons.
