A deadhead truck has a trailer attached but carries no freight. Deadheading means driving a cargo carrying truck (semi-truck) pulling an empty trailer. Deadheading often happens when a trucker returns or backhauls the empty cargo container to the point of origin. Be careful not to confuse “deadheading” with “bobtailing,” which happens when driving a cargo carrying truck without a trailer attached.
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.
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".
The axle of the truck broke.
You need to be more specific about the configuration. Is a single axle straight truck, a tandem axle straight truck, a tandem axle straight truck with additional lift axles, a tractor trailer...?
From the center of steer axle to center of rear axle on trailer. If you want just the truck it's the center of steer axle to center of rear drive axle.
#1 axle is the steer axle, #2 axle is the front drive axle, #3 axle is the rear drive axle.
Those designations actually exclude the steer axle, and only count axles behind the steer axle, so what you're talking about would actually be a truck with two axles - a steer axle, and a single drive axle.
A truck with three rear axles and one of the axles is a drop axle that is only used when carrying heavy loads.
What is the track width, or also known axle length of every truck?
It keeps the axle centered under the truck.
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.
Tandem axle dump truck. In some states, you may be able to put up to 15 tons on a single axle with an additional lifting tag axle.
