Speaking of Construction equipment......

[ArmySGT.]

Why not an encounter group built around construction equipment? There are truckers, bikers, and boatmen......

So why not one with dozers, excavators, dumptrucks?

They can be basically good. Repairing roads, building bridges, and clearing land for crops in exchange for food, fuel, and other consumables. On the other hand they can be bad guys that build fortifications for warlords, plow crops under, divert water from farmers, keep dozens of slaves as labor or entertainment.

Some names could be dozers, diggers, builders, breakers, struckshuns, or anything the language could morph into in 150 years.
