Cable drilling Winch?

[alegriarick]

Does anybody know how I can make or obtain a winch suitable for cable (or percussion) well drilling? It would have to hold enough cable to go at least 150 feet. It would need to have some type of free wheeling device with a clutch so that you can winch up the bit 6 feet or so then let it drop.

I think this is what you are looking for.

Do a google on Cable tool rigs as they are set up a little different for raising and dropping the bit. Lots of videos.

Are these rigs still being used? I have only been around one cable drill rig for one day, so you know this is coming from a real expert

Are you intending to sit at the winch to raise and drop the bit yourself? You'd go nuts in no time.

I don't recall the guys on the one rig I saw using the winch to do the actual drilling. They would send the bit down to the bottom of the hole with the winch, put on the brakes, then start up a second, reciprocating mechanism that would alternately pull on, then let down the cable.

If you look at a good cable rig the winch doesn't wind and unwind for the hammer cycle.

The winch is forward on truck go's 90 around a pulley on an eccentric then to the top of the rig makes a 180 back down to the tool.

the eccentric moves the 90 pulley up and down taking and removing cable to lift the tool and drop it.

Ill try and sketch it up

here is a sketch if it works

There is usually 3 winches one for the tool, one for the bailer, and one for the casing.

I'm just curious what are you trying to do.

here is a link to video you can see the pivot arm moving up and down and the crank going around.

I have seen some smaller units that use a break over or swing arm, on the drive wheel instead of a fixed crank,
it is attached at the center of the drive wheel and there is a peg or cleat that will catch it, and rotate it in the same manor as a fixed crank, but when it comes to the down stoke or the cable being released, the arm can swing upward dropping the bit faster, than what the drive is turning,

Oppsi, wrong information. The above would apply to the sandline or bailer but not the bit cable. It's a Seniors moment!

Here is a system from UK that looks great, and highly portable. http://www.consallen.com/forager/cable-tool/ I thought winches like this would be fairly easy to duplicate. I want to drill water wells for irrigation, but a friend wants to drill holes as cheaply as possible for geothermal installations.

With a cable drill you can go deeper for less money and equipment than a rotary drill. There is one on the internet which uses a cement mixer and a rope and a 2x2" Square tubing mast to hold the upper pulley. He has drilled wells in E. Texas for under $400 using this system. You can see it at www.lostcreek.net
Thanks for all the great responses.

For a drop hammer winch you could use a car rear end wit a spool on one end and and 2 mastercylinders to work like a crane friction, or the epicyclic winches. They worked good for makeshift pile drivers and pulp wood loaders back in the old days.
