Hey Trekkie.
I removed a warn 12,000lb electric, and installed an (imported) mile marker 10,000lb hydraulic. Mile marker is at www.milemarker.com
(by the way, an ox hydraulic is just a rebadged mile marker) Oh its on a 100 series diesel by the way.
OK, so, Electric, - draws upward off 450 amps, ( at max pull, then less with less pull), so you really should have a dual battery system. I used to get about 7 to 8 minutes winching before I notice the thing slowing severly, because it was both hot, and the battery terminal volts were dropping. I'd say the alternator was doing a hard job as
well. Low mount electrics drum's get hotter than the manufacturers of plasma rope (when i looked) would recommend for use.
Electric - was definitely faster recovery, (
Check the line speed of the high mount, it'd nearly give you whiplash!! ) - which is really important when your stuck in the bush, and you dont care how, but you just want get out, BECAUSE TIME MEANS EVERYTHING WHEN YOU COMPETE!! But i dont, so it didn't matter!!
True, Electric still runs when the engine isnt. - until the batteries goes flat.
Hydraulic. - draws 2 amps ( Solenoid power), More exxy to buy, does get hot (power steering fluid runs quite hot) but still ok for plasma rope.
Ive played with
mine for nearly 45 minutes one day, and the truck just idled away, like nothing even happeing.
One thing with a hydraulic, which a mechanic mate of
mine said - DONT increase rev's when you use hydraulic winch, - the power sterring pump is designed to make most pressure at idle - for when its hardest to turn the wheels, when you are sattionary. made sense to me.
To me the biggest downfall was the whole " but if the engine stops...blah..blah.." - but really when ive never had a diesel stop, even through sum very deep crossings, and other punishing times.
But - I was worried that tiny bit, so, my solution - I purchased a marine hydraulic 12V pump, capable of the required 1500psi at 3 GPM, and had it valved in series with the power steering pump. It draws 80 amps while running, less than the alternator output. but the winch gets its main power from the power steering pump, untill power steering pressure is lost, when engine stops, then i switch on the auxilary pump. - I also had to install a 6 litre hydraulic fluid reservoir.
Its quite wierd to have power assited steering, whilst the engine is off!! - not while winching though.
So, based on the above, I'm in favour of the Hydraulic solution. - and liked the fact the US army were retro-fitting all there humvee's with the mile markers...
Hope this helps,
Jarrod.
