Sell your semi truck for cash in Randolph the easy and convenient way

The Randolph Deep Mine records 103 employees underground.

It also sits on a dense road network: 737 structures within ten miles, in a circle that crosses the state line and picks up 95 more from the Kansas file for 832 in total.

An operation of that size runs a written specification, a maintenance department and a replacement cycle, so its machines leave with records. And because it is underground, the single most useful thing a seller can say is whether a given machine worked inside or on the road. At the same age those are materially different lives — a room-and-pillar mine runs at steady temperature and out of the weather.

That mine is not on its own. Four underground operations lie within twenty-five miles of one another here — 103 people at Randolph, 23 at Liberty, 23 at Mosby and 22 at Kingsville over in Johnson County, 171 underground between them.

It is a district. Kansas City sits on flat-lying Pennsylvanian limestones that are thick, uniform and easy to enter from a bluff face, so room-and-pillar mining wins out over stripping the overburden off — and the mined-out rooms get a second life as conditioned warehouse space. An operation whose voids have a use afterwards is not working to exhaustion the way a surface pit is, so its production and its fleet run steadier over a longer horizon.

A sand operation sits here too, 14 employees under Holliday Sand & Gravel — a company that also turns up four times in the Oklahoma production returns.

The roads are the Kansas City pattern. Twenty-nine structures within ten miles are rated below legal loads against 138 carrying a posting, only three of them county-maintained, the nearest 2.79 miles out. The lowest that admits a loaded commercial vehicle is rated about 18.8 US tons. Clay County restricts 18 of 72 — a quarter of what it maintains — while Jackson County across the river restricts 1.1 per cent, so a truck’s road history here depends entirely on which side of the water it worked.

• The opposite, usually, and here it is the single most useful thing you can tell us. A room-and-pillar mine runs at steady temperature and out of the weather, so a machine that stayed inside has had a very different life from one that ran the roads.
• It worked south of the river rather than here.Clay County restricts a quarter of what it maintains and Jackson County across the water restricts about one per cent, and there are few crossings between them. Same market, very different road history.
