Hydraulic Elevators

And now for something different, a real gold topic!

This was a hydraulic elevator used in Breckinridge, Cc. in the early 1900's. It used water at 182 psi and lifted -8" material 100' straight up to the sluicebox on top. Bedrock was hit at 73'.

Re: Hydraulic Elevators

Cool photos, Leonard. I never cease to be amazed at the lengths to which men will go to get to gold. We look at the somewhat primitive equipment and methods the old timers used and wonder how they could manage. I remind myself that they considered what they had as "state of the art"...just like we consider our fancy, schmancy mining stuff as the best available. It, too, will someday be looked at as primitive.

What? Wanna compare your dredge to this hydraulic elevator? It is just a suction nozzle, nothing more. Wanna bet your dredge nozzle can compete with this so-called primitive junk? The hydraulic elevator was well engineered and made of cast iron.

Think about it. 8" rocks lifted 100 feet with 182 psi. I ain't convinced it was primitive.

Re: Hydraulic Elevators

Simple gravity.

Basiclly what they did was take the water canon(Monitor)from a hydraulic operation and plumb it into a large tube, creating an eductor jet just like the one on your dredge. They'd use this to lift gravels from a pit up to an elevated sluicebox, often using other Monitors to drive pay gravel into the feed pit. Most of the gold recovered in the operation came from eventual cleanup of the pit itself with the sluice acting as a secondary recovery.

This system was most often used in areas that didn't have adequate dump for the tailings of a 'normal' hydraulic mine. By elevating the gravels, it was possible to work low ground(even submerged ground)and still have drop for the sluice and somewhere to run the tails.

Re: Hydraulic Elevators

The source was 4 miles of ditches and 8,000 feet of pipeline. The ditches and pipeline had a capacity of 6,000 miners inches and 350 feet of head. The pipeline used 5 foot steel made in their own local shop.

The source of the pictures is a book, Gold Pan Mining Company and shops. 64 pages from Quandry Press
PO Box 566
Breckinridge, Co
80424
303-453-0536

It is filled with black and white pictures of the system and shops.

I just looked and Amazon has several for less than $10.00.

Re: Hydraulic Elevators

ThankYou Leonard! Great brainfood makes a guy want to upsize :devil: smaller version Hmmmmmmmmm??? Got the timber the whole county is loaded with beatle killed lodgepole acres and acres of it. Could get old underground ore cars to tram it by rail down the stream canyon to dump in cribbed terraces. But I dont think the forest service and blm would like me stealing a 2X5 ft stream to feed it, Dang!

Re: Hydraulic Elevators

John Ewing, Central Otago "Gold Baron" in New Zealand had elevators that lifted wash in excess of 135 ft during the late 1800's!

His elevators are still in place under the blue lake at Saint Bathans.

Thanks.
There were a few pictures posted on my forum that would have been harder to move.
