On various work vehicles (trucks, diggers, etc) at construction / mines sites, I see there are alpha-numeric codes often placed on the side (e.g. WT13 as shown below.

What do the codes represent? How to they get determined?

Pretty sure that one stands for ‘water truck 13’. Don’t know about the 796D but it could be the capacity of the diesel powerplant.
Company fleet number.

So there can be duplicates? Our base is one huge construction site right now (not even the runways are free from them) and there are utes, traytops, etc, all with these numbers and i wondered who decides what number goes on what vehicle.
purely arbitrary, whatever numbering convention the various companies have for their vehicle fleets.
also used as UHF call sign on site and for gps id tracking
The 760D is just the Caterpillar model number.
All the manufacturers have a different system.

yeah, but at 350 degrees, they cause more fires than they put out…
In the army the numbers on the trucks etc are the numbers from a master ledger held by the QM that relate to the establishment table which is authorised at Canberra so relates to numbers there as well, the establishment being the units authorised holdings. I don’t know the ins and outs but the number can trace the individual holding down to a unit level and its position on the table.
water truck 13
being 13 the water has been blessed by a priest
in the event of zombies breaking through the perimeter, this water is sprayed onto the rampaging hordes to contain the situation
if you have been bitten by a zombie you should flush the wound with this holy water
Thinking about it some more, I imagine it would be as simple as the unit establishment number and then three digits identifying the paralone number in the ledger. So if you were in the know you would know that 5 being Queensland and other numbers equals a Queensland unit, and if you read down to say 346 paraline number it would tell you it was a landrover on the establishment ledger.

So they would renumber army vehicles if transferred to other units?

for a horse add 1
for a goat add 2
for a pony add 3
for a dog add 4
for a bird add 5
and so on
in wartime regimental mascots could be swapped at will to confuse the enemy

Possibly if it was a “posting”. Soldiers are on the establishment table as well, if you get seconded to another unit it is just noted on the paraline number as being detached. If the vehicle was taken on the other units strength it would be given its new unit establishment and paraline number and the original unit would mark it on its own ledger as being taken off strength leaving the place open for a new vehicle.
That is how units get get reformatted or downgrade etc, Canberra adjusts the establishment tables.
Letters are often the contractor’s code, some abbreviation of the company name, plus a number for the individual vehicle.

The 769D is the model number – determined by the manufacturer
The WT13 is the asset number – determined by the operating company
In this instance the WT stands for Water Truck…
Found this on the back of a truck.

Water Truck 13
7 is the type of vehicle. 7= Water truck, 3=Excavator, 9=Loader, 2=bobcat, 8=Compactor,1=Grader. Though they have some variations, and some companies ignore this guide.
69 is how many tons it weighs.
D is the series. A = first model, B=next model, D = current model, so E = next model. F = future model, etc.

amazing- this actually came up in a google search I was doing
havent been here in ages so waves hi
7 isnt a water truck code in the cat range- close, but no cigar
7 is the code for an `off highway truck’- ie anything designed for heavy off road purposes- it can be fitted with a range of bodies depending on application (eg tippers are the most common use in mining)
not sure how the next two numbers are determined as checking their webpage, it definitely isnt to do with the weight
not sure on the last letter either as they also use 2 letter codes for some chassis’s (eg 794 AC ) and they have from a to g on different models, and some have no letters at all on the end….
(http://www.cat.com/en_GB/products/new/equipment/off-highway-trucks.html)
the yellow `WT13’ is the radio callsign/ item `rego’ number- in this case it is WT for water truck, 13 being the asset number (so they have at least 13 of these things in their company), it is allocated by the owning company in whatever format they please- often outside contractors will have the company name and unit number (eg Hertz rental utes have a HERxxx number) while minesites utes will usually either be the mine name and number- or LVxxx the second being a `light vehicle)
