If you have experience operating a Class 8 truck, you should have the driving part down. If not, I would suggest you go to a truck driving school - you're not going to learn how by simply reading about it. As for the PTO controls, it depends on which PTO system you have. Normally, you push in the clutch, engage the main PTO control, let off the clutch, and use the secondary PTO control to raise and lower the dump body. Some systems differ, however.
It's a dump truck with four axles--the steer axle in front and three axles in back. One of them moves up and down via a control in the cab, so the tires aren't on the road if the truck's not loaded. A tri-axle dump truck carries more weight than a one-axle or two-axle truck.
A North American truck will be 96" wide.
That's going to depend on the dump truck's configuration. It could be a single axle, tandem, tri-axle, quad axle, quint axle, centipede, frameless end dump, framed end dump, etc.
12 or 14. Depends if lift axle has dual tires or not.
In the vicinity of 22,000 - 25,000 lbs.
The amount of dirt a dump truck can hold depends on the size of the dump truck. The average tri axle dump truck can hold 12 cubic yards of dirt, and a quad axle can hold 14.
A dump truck with two (tandem) rear pulling axles supported by a third fixed axle located in the middle of the truck which only reaches the ground after a certain amount of load weight.
It varies from state to state, and will also be dependent on the tare weight of the truck. I can tell you that, in North Carolina, 13 to 15 tons is the norm for a tri-axle dump truck.
Need to know the specific model and configuration (e.g., single axle, tandem, tri-axle, quad axle, centipede) in order to answer this.
Varies by state. In North Carolina, a tri-axle is generally good for 15 - 17 tons, depending on the tare weight of the vehicle.
Go to a truck driving school. You're not going to learn how to drive a Class 8 truck by reading about it on this website.
Wages differ from job to job. The contractor you are working for will be able to provide you with them. Dump trucks (single & tri-axle) are Truck Driver Class 2.
