Johnson County
A restricted crossing six tenths of a mile from a plant that moves
MSHA records 4 employees at Portable Plant #3, under Capital Materials, LLC. Its recorded point sits 3.15 miles from the middle of Leeton — not a stated address, so read the distance as an approximation.
The lowest rating among them is 6.3 tonnes, barely half the 11.0-tonne tare of an empty tandem dump, so nothing commercial crosses it in either direction. The lowest that does admit a truck is rated 13.5 tonnes, about 14.9 US tons, leaving roughly 2.5 tonnes of stone over that tare against the twenty-five a legal 80,000 lb truck carries.
Two and a half tonnes is not a load. A crossing rated like that does not trim a haul, it ends it — the truck goes over empty or it goes another way. Across Johnson County as a whole 33 of 375 county-maintained structures fail item 70, 8.8 per cent against 12.7 across Missouri’s counties, so the problem near this plant is concentrated rather than general.
That word portable is doing real work in the name
That the plant moves is the thing most likely to explain a truck you are selling out of this town.
Capital Quarries and Capital Materials hold twenty-eight sites in the Mine Safety and Health Administration’s mine data across eight states — Missouri, Arkansas, Arizona, Kansas, Michigan, Montana and Texas. A portable operation is a crushing plant that is trucked to the stone rather than a pit the stone is trucked out of.
What follows for the equipment is that most of it around a plant like this is haulage rather than fixed works, and a machine may carry hours from more than one site. That changes what the hours mean when you describe the truck.
Eleven of the twelve are county-maintained, and a cap in the teens admits only a couple of tonnes over an empty tandem’s tare.
Around Portable Plant #3 — four people on the MSHA roll, its recorded point 3.15 miles out from the middle of Leeton — and across Johnson County and Pettis County, this country turns over a steady amount of it.
- A plant that moves puts hours on a truck across several sites rather than one, which is useful for us to know and is not a mark against it.
