unclebill Posted October 27, 2006 Share Posted October 27, 2006 Hi, anyone shed any light on the specs of the Warn 12 Industrial hydraulic winch that i've obtained through eblag, its rated at 5500kg, but anything like gearbox ratios, flow rates etc would be helpful, ,its also got a divided spool almost like it was designed for twin cables, any ideas. Cheers Bill Tis a bit of a monster, but think I can get it to fit, goodbye 2 inch lift. Quote Link to comment Share on other sites More sharing options...
jericho Posted October 27, 2006 Share Posted October 27, 2006 Try this H12 The drum was divided by a previous owner - probably just to increase the number of turns as it is a large drum for a hundred foot cable. nearly went for it myself,was suprised at the motor size.

unclebill Posted October 27, 2006 Author Share Posted October 27, 2006 Try this H12 Thanks , just what I wanted. Quote Link to comment Share on other sites More sharing options...
jericho Posted October 27, 2006 Share Posted October 27, 2006 motor is about 4.5 cubic inches,as opposed to the mile marker 12000 which is about 18 cubic inches.Don't know much about hydraulics ,but would be interested to know what sort of pump would be required to make the warn work well.if anyone can shed light...

Hybrid_From_Hell Posted October 27, 2006 Share Posted October 27, 2006 If my memory is right most industruial superwinch (and a H12 is) will take 50-60 LPM from a PTO driven pump, prob you will have is that for a series 2 unit (Superwinch PTO face mount) this stops at around 30-32 LPM series 3 takes you to this output but the face plate is biggwer and doesn't fit Just means the winch runs slower than its design max HTH nige Quote Link to comment Share on other sites More sharing options...

Right ready for the comments, good bad idea, I'll still go ahead and build the unit anyway, just to see how it performs. Bill Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted October 27, 2006 Share Posted October 27, 2006 In simple terms it has merits. But the PTO on say an LT230 at engine speed of say 1500 RPM and a 30 LPM pump shifts a LOT of fluid, not sure what you are proposing will. However, you may fiond that with a decent battery and pump it shifts more than an engine driven PAS and MIlemarker winch......although that needs less volume shifted to move it I'm sure mafhs clever with number blokeys will give you more accurate numbers...... But interesting non the less.... Nige Quote Link to comment Share on other sites More sharing options...
LR90 Posted October 27, 2006 Share Posted October 27, 2006 Does the higher volume requirement equate to lower pressures with the H12? Quote Link to comment Share on other sites More sharing options...

dollythelw Posted October 27, 2006 Share Posted October 27, 2006 ping me as much info as you have Unclebill and I'll do the maths for you, need to know rpm of the leccy motor, cc/rev of the pump and working pressure (if you can dig it out), torque or HP figure for the leccy motor would be helpful as well Quote Link to comment Share on other sites More sharing options...

jericho Posted October 27, 2006 Share Posted October 27, 2006 Hybrid - this is the warn h12 not superwinch h12,very different,but yes it is rated as 60 l/min max flow. Dolly - warn h12 has a motor about a quarter the capacity of the milemarker h12,does this mean it requires a quarter the flow of oil?It can't be that simple.

dollythelw Posted October 27, 2006 Share Posted October 27, 2006 Milemarker 1:1 low gear ratio Warn 36:1 its a higher speed lower torque motor than the milemarker, hence the lower CC/rev Quote Link to comment Share on other sites More sharing options...

Bull Bar Cowboy Posted October 27, 2006 Share Posted October 27, 2006 Most of the specs are on the website …….. Max flow 60L/min @ 1820psi = 24ft/min............... g/box is 36:1 so the motor must be doing 830rpm @ full rated pull ........... drum is 4inch dia so it will recover 12.5inches per rev. Flowing less = slower, but is not linear on most motors. Less working pressure will result in less max torque, again not exactly linear in most applications. Beware of altering the fluid capacity of the tank as you may run into overheating problems. Most commercial applications run anything from 2:1 to 4:1 tank size, based on the pump flow….i.e 60L/min flow would be sized as a 120L to 240L tank. As our uses are classed as intermittent, it is common to use 0.5:1 (60L pump = 30L tank). The laws of physics tell me you are not going to get something for nothing ……….. so I would expect a hefty current flow to the leccy pump motor when the winch is at full chat. Seems a long way round to get a result …………. Putting leccy in there will just increase the losses …………. Better to go PTO Ian Quote Link to comment Share on other sites More sharing options...

Better to go PTO Ian Cheers Ian, must admit I've been waiting for your comments as I read your other stuff on hydraulics when I was putting this idea together, points taken, i,ve thought about the overheating but unless in a competition I don't think that would be a problem, currant load, yes thats why I've gone for a winch motor, used to working hard and the battery is a mother of a battery, point taken about a PTO, but whilst my V8 swims well its the thing that you need a winch when your in the mire and its possible that all is dead, drowned whatever and the battery should then have enough to pull to somewhere sensible. Pleased you stayed on by the way, your tech info on hydraulics has been very useful. Cheers Bill Quote Link to comment Share on other sites More sharing options...
dollythelw Posted October 28, 2006 Share Posted October 28, 2006 you'll need cc's/rev for your pump and the torque rating of the motor - without those you're going to be flying blind. milemarker 1:6 high speed, 1:1 low speed Quote Link to comment Share on other sites More sharing options...

Better to go PTO Ian One more point on this: the worm and wormwheel have a efficiency of about 25%! So the losses in this powertrain from engine transformed into line pull will be horrendous.

dollythelw Posted October 28, 2006 Share Posted October 28, 2006 my brain and fingers not talking to each other - soz 6:1 low gear 1:1 high gear doh! will reconnect fingers with brain and try again Quote Link to comment Share on other sites More sharing options...
