We buy trucks in Mascot

Two operations sit under Mascot. The Immel Mine works zinc underground with 140 people, one of five Tennessee rows controlled by Korea Zinc. Martin Marietta works the Midway Quarry with fourteen, approved for state highway work and matched at 0.74 miles.

The interesting number here is not either workforce. It is the road network, which more than doubles across one county. Within 10 miles of this town the inventory records 178 structures; within 10 miles of the Riverside Drive pit in the city, twelve miles south-west, it records 439.

Same county, same weight law, same producer group — and a truck working out of here meets less than half the bridges a truck working out of the city does. Knox County posts 9 of its 131 county-maintained bridges, 6.9 per cent, but that single figure hides the difference entirely.

That density matters because of where the ore actually goes. This town, Strawberry Plains and Jefferson City all lie within thirty miles of Knoxville, and the mine-to-mill haul roads are roads people live on. It is the only underground mining district on file whose truck traffic runs through suburbs.

So the driving is short repeated runs at moderate speed with junctions, traffic and sheeting discipline in the middle of them. Brakes, clutch and suspension take the load; the top end of the engine barely gets stretched; idle hours build at gates and weighbridges rather than on a highway.

An ore hauler is heavy work regardless of the road — dense material, full loads, and a body taking the impact of loading every cycle. If you are selling one out of the Immel Mine, the body and the frame are what anybody will look at first.

Those quarry trucks come off a narrower ownership than the names suggest. Two national producers hold all five Knox County quarries between them: Vulcan Materials at the Everett Road and Riverside Drive sources, Martin Marietta at Heiskell I-75, this town and John Sevier Highway.

The node list gives five unrelated-looking names and its operator field does not group them the way the register does. So most of the used stone iron that reaches this market has come off one of two replacement plans rather than out of five independent yards.

A national producer runs a standard specification, a scheduled replacement cycle and a maintenance system that outlives any individual machine, so the records usually exist. The honest other half is that a machine off a replacement plan was worked to that plan rather than spared.

Both fleets run under a statute that hands the ore side and the stone side the same nothing.

Tenn. Code Ann. § 55-7-203 sets 80,000 lb gross, 20,000 lb on a single axle and 34,000 lb on a tandem, with up to 550 lb more for emissions-reduction equipment. Subsection (b)(7) grants a ten per cent margin of error on the weighing to logging, sand, coal, clay, shale, phosphate, solid waste, recovered materials, farm trucks and machinery trucks — off the interstate system only. Crushed stone is absent, and so are limestone, aggregate and gravel.

Tenn. Code § 47-26-812 adds an axle-citation shield and five hundred pounds for a natural resources load, from a weights-and-measures chapter about certified public weighers rather than the motor vehicle code. Off the interstate again.

And § 55-7-104 is the one that costs a working day: an overweight vehicle may not be moved until the load is reduced into compliance or a permit obtained, and failing to comply is itself a Class C misdemeanour.

Tenn. Code Ann. § 55-7-203 and § 55-7-104, and Tenn. Code § 47-26-812, as summarised by the University of Tennessee County Technical Assistance Service. Information, not legal advice.

Beyond the weight rules, the paperwork is one sentence.

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. Neither one stops a sale.

The salvage rule is the one people repeat wrongly. Tennessee’s salvage and rebuilt part is built on the term passenger motor vehicle, and § 55-3-201 defines that as a vehicle ten model years old or less which, if it is a light-duty truck or a multipurpose vehicle, is rated at not more than nine thousand pounds gross.

So the seventy-five per cent threshold does not reach a truck rated above nine thousand pounds at any age, and does not reach a vehicle of any kind over ten model years old. Those limbs describe the class the part governs rather than exceptions inside it. Whether some other provision reaches such a vehicle was not determined and is not claimed here.

Tenn. Code Ann. § 55-3-201 and § 55-3-211, with the Tennessee Department of Revenue’s guidance. Information, not legal advice, and only as current as the day those were read.

All of that iron is iron we buy. Ore haulers and heavy tandem dumps off the Immel Mine. Aggregate haulers off the Martin Marietta pit, 0.74 miles from the register’s own point.

Day cabs, road tractors, box trucks, straight trucks, flatbeds, rollbacks, tankers, service bodies, work trucks and pickups too — not a Knox County thing in particular, they run everywhere.

Whatever you drive, the offer doesn’t change. We buy all of them.

• 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.
• The engine is out of it. Is that different?Yes, and that is the line. A tired engine is fine; an engine that has been pulled and sold means we can’t buy the truck.
• What about the title?We need one unless the truck is old enough that it never had one. Lost titles have a counter replacement, and where none exists there is a bonded route.
• It hauled ore through the houses for years.Then expect the wear in the brakes, the clutch and the suspension rather than the top end. Around the Immel Mine that is the normal shape of a working truck.
• It came off a Martin Marietta cycle.Then a maintenance file probably exists, and there is a comparable machine at the other Knox County pits to set it against.
• How do you pay?Cash or electronic payment, whichever suits you.

Beyond a machine that has simply done its cycles, the reasons here are personal ones. Retiring. A medical that went the wrong way. A contract hauler losing a run to the mill and having one truck too many the week after.

The yards along the Immel Mine road and out towards the Martin Marietta pit usually have one standing that came off a haul contract and never got another.

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.
