Most of them fall between 2 tons and 6 tons, but some are over 10 tons.
That's talking about a vehicle, not an axle. A 6x2 vehicle has six wheel assemblies, and two are driven. So you'd be looking at three axles total (two wheel assemblies per axle), one of which would be a live axle with a differential, and the other two would be dead axles which are not driven... there'd be a steer axle, and the other dead axle could be a stationary axle, or it could be a lift axle. The powered axle could be either the forward or rear drive axle - it doesn't have to be one or the other.
The F350 is a two axle vehicle.
A dually vehicle is typically a truck that carries heavy or large loads and that has 4 wheels on one axle instead of the usual two wheels on one axle.
The axle shaft serves two combined function's, it supports the weight of the vehicle and delivers torque to move it.

Two axle, rigid body on a car means that there are two axles or four wheels and the body is one solid piece. This means that the vehicle does not have a vinyl top.
This is a type of steering most commonly used on vehicles carrying large loads such as fixed bed lorries, it is essentially when such a vehicle has more than one steering axle. It can either be the front two axles in a six axled vehicle or both axles in a vehicle with the usual two axles. If it is two front axles then the degree of steering angle on the second axle is much less than the first and is dictated by the distance between the two front, and the distance to the next axle, as well as the length of the axles themselves. On a vehicle with just two axles where both are steering then the rear is used as a method of improving cornering abilities, on a normal corner they must steer in opposite directions but in certain such vehicles - like monster trucks - the steering is independent to allow the vehicle to 'crab' sideways, vastly improving manouverability.
It looks like a dump truck that has another axle in front of the tandems at the rear of the vehicle. Most people who have these trucks have a mechanism to allow the fourth axle to be raised when it's not needed.
They vary by manufacturer, passenger capacity, etc. Some are under CDL weight, but still require a CDL, as they are designed to transport more than 15 persons (including the driver). The highest gross weight which a school bus would be allowed is 33,000 (35,000 in some states), as that's the max allowable weight for a two axle (steer axle and drive axle) vehicle. So you're at anywhere between 22,000 to 33,000 lbs, variables considered. wow your smart! {a comment}
There's no such thing as a one axle truck. There has to be a minimum of two axles. "Single axle" if a term referring to a truck with only a single drive axle, and doesn't count the steer axle. Same with "tandem axle", "tri axle", "quad axle", and "quint axle".
Five, all told. The steer axle isn't included in the count, so a single axle with have two - a steer and a single drive axle, a tandem will have a steer axle and two drive axles, a tri-axle will be a tandem with an additional lift axle, a quad axle will have two additional lift axles, a quint will have three additional lift axles, and a centipede will have four additional lift axles. A superdump is usually a quint with an additional Strong Arm mounts to the top of the dump body which extends out to maximize the vehicle's wheelbase.
They weigh twelve oz to two lbs
