Pima County
A hundred and fifty people at a cement plant, and three at a stone quarry
Two rows are filed at this town and the gap between them is the story. The Rillito Plant, operated by CalPortland Company, works cement and reports 150 employees, with its coordinate 3.86 miles from the middle of town. The other is a dimension-stone quarry called Silver Bell, operated by Rock Pros USA, and it reports 3.
A cement plant is a different animal from a pit. Cement moves in bulk tankers and in mixers rather than in dump bodies, it runs to a schedule set by pours rather than by a stockpile, and a plant of that size supports a standing haul fleet in a way a three-person quarry never does. Both are filed here; only one of them puts trucks on the road every day.
Where those trucks go is the thing worth knowing. This state has two markets and no third: the plant here serves the Tucson side, and the cement plants a long way north serve the Phoenix side. Those distances are read from general geography and are approximate rather than measured, so treat them as shape and not as figures — but the shape is real, and it means a plant that misses its metro has nowhere else to sell into.
So the fleet here is bulk, and bulk wears differently
Those 150 employees at the Rillito Plant sit behind a kind of truck we see a lot of and a lot of pages never mention.
Bulk cement tankers and mixers carry dense product in a pressurised or rotating body, which puts constant load on the driveline, the PTO and the air system rather than on a tipping ram. A mixer in particular spends its life turning a drum whether it is moving or not, so the engine hours run far ahead of the odometer and the front axle carries weight the whole time.
That is why we ask what body was on it before we ask the mileage. A truck out of Pima County that spent ten years under a mixer barrel and a truck that spent ten years pulling a flatbed have the same number on the dash and nothing else in common. And the three-person quarry at Silver Bell puts the opposite kind of truck on the same roads — occasional, light-duty, long gaps between jobs.
Arizona weight law
One axle number, and the tolerance is already inside it
Bulk or stone, it all moves under a state figure written differently from most.
Arizona sets the single axle at 20,000 lb under A.R.S. § 28-1100, and the enforcement tolerance is included in that number rather than added on top of it. Alabama is the only other state on file that builds it in the same way — Georgia, Kentucky and Florida all publish a base and then allow something over it. So a driver who has worked one of those states and moved here can arrive expecting headroom this section does not give.
The gross limit is a different matter. It was not extracted from the section text when the rule file was compiled, so this page does not state one. An unverified ceiling is worse than no ceiling, and the section itself is where the answer is.
A.R.S. § 28-1100. Information, not legal advice, and only as current as the date the rule file was last verified.
Arizona paperwork
We need a title — unless it never had one
Beyond the weight rules, the paperwork is one sentence and then a set of fixes.
Everything after that sentence is a fix rather than a category. A lost title has a counter replacement. Where none exists there is a bonded route. Both are ordinary and neither stops a sale.
Arizona has no percentage threshold for salvage. A.R.S. § 28-2091 brands a vehicle salvage where it has been stolen, wrecked, destroyed, flood or water damaged, or otherwise damaged to the point that the owner, the leasing company, the lender or the insurer considers it uneconomical to repair. That is a judgement rather than an arithmetic test, and the wording sits closest to California’s. Four of the seven states on file work this way; Kentucky and Alabama use 75 per cent and Florida 80.
There is also a separate nonrepairable class, and A.R.S. § 28-2095 covers the restored salvage certificate — its inspection triggers were not extracted, so this page does not describe them.
A.R.S. § 28-2091, § 28-2095. Information, not legal advice.
What we buy here
Those rules land the same way on every body style, and so does the offer. We buy all of them.
Mixers and bulk tankers off the cement side, tandem and tri-axle dump trucks and aggregate haulers off the stone side, day cabs and road tractors, flatbeds and stake beds, water trucks, service bodies, box trucks, rollbacks, and the crew pickups behind all of it. Box trucks and straight trucks are not a Pima County thing in particular — they are everywhere — and we buy those too.
This is close enough in that every way of doing it is ordinary: we come to you and drive it away, we come to you and tow it, we buy it remotely and arrange the tow, or you drive it to us. With 150 employees at the Rillito Plant and 3 at Silver Bell, almost all the equipment around here belongs to owner-operators and small hauliers rather than to either of the two rows on file.
We buy complete trucks. If the engine, transmission, doors, rear ends, drive shafts, wheels or anything under the hood have been removed, we can’t buy it. Small things — a missing bumper — are fine.
Straight answers
The questions we get asked in Marana
- Does it have to run?No. It does have to be complete — if the engine, transmission, doors, rear ends, drive shafts, wheels or anything under the hood have been removed, we can’t buy it. Rust is not a disqualifier.
- Do you buy mixers?Yes, and cement tankers, and everything else. The offer does not depend on the body. With a cement plant of 150 employees 3.86 miles from the middle of town, mixers are simply what turns up here more often than elsewhere.
- My hours are high and my miles are low.That is normal on bulk work. A drum turns whether the truck is moving or not, so we read the hour meter, the front axle and the air system before the odometer.
- What is actually filed at Marana?Two rows: the Rillito Plant under CalPortland Company at 150 employees, and a dimension-stone quarry called Silver Bell under Rock Pros USA at 3. Note that this Silver Bell is dimension stone and is not the copper operation of the same name filed at Tucson.
- What is the axle limit?20,000 lb on a single axle under A.R.S. § 28-1100, with the enforcement tolerance already inside that number. Do not add anything to it.
- What about the title?We need one unless the truck is old enough that it never had one. Lost titles have a counter replacement; where none exists there’s a bonded route.
Why people call
Those are the mechanics. The reasons behind a call are more personal than that.
Retiring. A medical that did not go the way it used to. A contract that ended, or an outfit that has grown out of one truck and into another and needs the first one gone. Around a plant employing 150 people there is a ring of small hauliers doing the deliveries the plant does not do itself, and a three-person quarry like Silver Bell is one truck away from being nothing at all. Those are the outfits that call, not CalPortland Company.
Most of those aren’t happy reasons, and we don’t treat them like they are. Somebody wants a straight answer and the truck gone by the end of the week. That’s what we’re here for, in Marana and across Pima County.
