Yes, so long as the combination is within weight and bridge law regulations.

Semi tandem truck?
The "tandem" part means it has two drive axles, although it is possible for a tandem truck to be a 6x2 vehicle, and have only one of those be a live axle.
What is the difference between a normal dump truck and a tandem dump truck?
A tandem dump truck is as normal as any other dump truck. Tandem simply indicates that it has two drive axles (as opposed to a single axle, which only has one). A tandem dump is typically allowed to gross at 54,000 lbs. From there, some dump trucks have additional axles (lift axles) which allow them to haul more weight. They're named in accordance with the number of axles behind the cab (i.e., not including the steer axle). So a tandem dump with a single lift axle would be referred to as a tri-axle, with two lift axles it would be referred to as a quad axle dump, with three lift axles it would be referred to as a quint axle dump.... at four lift axles, they're typically referred to as 'centipedes'.
Do both axles on a tandem truck have a ratio or is one free turning?
Neither is turning freely in a twin screw drive configuration.
How much does a concrete mixer truck weigh?
They come in many sizes and configurations. They could be single axle trucks, tandem axle trucks, tandem axle truck with additional lift axles, tandem axle trucks with a twin steer setup (and these may also have additional lift axles, as well), and even tractor-trailers with mixer trailers. You'd have to be a little more specific as to which one you had in mind.
What is a tri-axle truck?
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 a split tandem axle and does one axle always stay all the way to the rear of the trailer?
A split tandem axle is one where the axles on the trailer are several feet apart. There are 2 types of these. One set if "fixed" and cannot be moved and the other you can pull the slider pin to move them to adjust your weights so your legal. Hope this helps! (BTW if you don't know what I'm refering to this question and answer are for 18 wheelers.)
What is a tandem truck?
A tandem truck usually refers to the amount of axles on the trailer or tractor. A single drive axle on a tractor would be referred to as a single, or the same for one axle on the trailer. I have seen it referred to the amount of tires on the end of an axle. When there are two tires on the end of the axle, that would be referred to as a dual, not a tandem.
What axle drives a tandem truck?
There are two configurations for a tandem truck... the first - more common in Europe - is known as "single screw". The driveshaft goes to the differential of one axle, and that's the only live axle. In cases such as this, the additional axle is typically a lift axle. In N. America, tandem trucks normally use a twin screw configuration, where the driveshaft goes to a power divider... that power divider is essentially a differential, and has outputs going to both axles... ergo, both axles have power supplied to them at all times. A lot of people think that the power divider lock engages one of the axles.. this is not true.. it simply locks the outputs so that they always rotate at a matching speed.
Why do some semi tractors have twin steer axles?
Tandem steer axles are primarily employed in vehicles because of that particular vehicle's load distribution, per-axle weight limits and bridge formula issues. They're often used for crane applications, large cement mixers, dump trucks, and for some oversize load hauling applications, etc. -- vehicles where a single steer axle would be inadequate or undesirable. Single axle load limits are typically 20K pounds, tandem load limits are typically 34K lbs. How both the payload weight is distributed and how the axles are distributed can have a substantial effect of how much weight a particular axle has to carry, and to remain legal additional axles are required -- however just putting extra axles around the rear drive axles will do little to ease a heavy forward located load. Also, with tandem steer axles the tires are actively turned, unlike tag axles which tend to passively turn/align themselves (or not turn at all). By having a couple active steer axles one can gain a more positive steering response (not to be misinterpreted as meaning a tighter turn) which can be particularly useful in off-road applications, and by having the forward (steering) axles actively aligned in turns rather than having an extra forward placed axle just passively tagging along (sorry, had to) less tire scrubbing should result.
What is a quad dump truck?
A quad axle dump truck is a tandem axle dump truck, with additional lifting pusher and/or tag axles. The most common configuration is two steerable lift axles in front of the drive tandems, although some will have one pusher in front of the tandems, and a tag behind the tandems.
What is tandem network?
One in front of the other
What is a quad-axle dump truck?
A quad axle dump truck is a tandem axle dump truck, with additional lifting pusher and/or tag axles. The most common configuration is two steerable lift axles in front of the drive tandems, although some will have one pusher in front of the tandems, and a tag behind the tandems.
