I would like to see 20 cubic yards on a tandem. I would hate to pay that overload ticket.
it depends on how big the dump truck is
Dump trucks typically don't haul liquid commodities, unless you're thinking of snow removal operations where they'll be outfitted with prewet or calcium chloride tanks. Even with that in mind, you need to remember that there are many different sizes of dump truck out there. 15 cubic yards is "typical" for a tandem axle dump truck.
It depends on the size of the dump truck.
How many liters a dump truck holds depends on the size of the bed of the truck. A small dump truck can hold about 1,024 liters.
Three - the two drive axles, and the steer axle.
Legally, as much as it's rated for. The legal GVW of a dump truck depends on configuration, local law, wheelbase, and other factors. For a tandem axle dump truck, they can typically legally carry between 13 and 15 tons.
Provided it's not a short tandem, 15 yards with a 'rock tub' dump body and 16 yards with a 'dirt tub' dump body are typical.
Dump trucks come in many sizes and configurations. Additionally, vehicle weight laws vary greatly between countries. We would have to have some idea of what configuration and jurisdiction you had in mind. Configurations of dump trucks would include single axle, tandem axle, tandem axle with twin steer, tri-axle, quad axle, quint axle, centipede, tractor-trailer end dump, etc.
Dump trucks come in many shapes and sizes, and the same holds true with dump bodies. For a tandem, 13 - 15 tons is typical.
