At least new to me. I don't use a hydraulic winch, but saw these and thought they were pretty nice.

Wow, never heard of them. Didn't look too hard at where to buy or import them, but they look pretty good, and fast for hydraulics. Nice find! How much in US dollars?

Best of Luck,

Those do look nice... high quality and purrdy.

However, those numbers wouldn't be the same on our Jeeps. I converted their specs over to US and for their Sabre winch:

Flow Rate: 20 L/min = 5.3 gpm
Pressure: 200 bar = 2901 psi
Force/Load: 4500 kg = 9921 lb
Line Speed: 24 ft/min

On my home computer I have a spreadsheet with specs for our Jeeps, but off the top of my head I think the Jeep stock at idle is 2.4 gpm of flow @ 1500 psi. Flow corresponds to line speed and pressure relates to the force/load. So roughly, on the first drum wrap, the force/load would be 4800 lb @ 11 ft/min for the Sabre. Granted, that is faster than my Milemarker, but they traded off load capacity for line speed by using smaller displacement motors. For reference, I think my 10500 lb MM can pull around 9900 lb @ 4 ft/min on the first drum wrap on my stock Jeep at idle.

I made some pretty nifty charts I should post up about the effects of different PS upgrades and snatch block configurations on the line speed and load capacity of the MM winches in high and low gears. I also threw in the electric winches my friends use for curiosity's sake because I was sick of them always making fun of my poor ol' slow hydraulic, but it didn't solve anything because it IS slow! :laugh:

I would love to see that kind of data. When I first saw these, my first thought was about the pump and how it would work with a hydraulic winch. Do you know of any upgrades for our jeeps? I thought AGR made some but I'm not sure if they had them for the 2003+ models.

Here you go, Specs on the pump are at idle this is just one of several options for a jeep.

That PSC pump does the following:

1600 psi and 4.5 gpm

That is a step in the right direction to get to the number the Red Winch is posting.

I would expect these to be very expensive, but seem very high quality. Even for the price they sold in England, once you get them here, and pay duty you can add anywhere from 20-30% before dealer mark-up.

Yes those AGR/PSC aftermarket pump kits are what you have to do... However the other thing to take into consideration is the flow limitation of the stock valve assembly (manifold and valves) that comes with the MM winches. I forget what the actual number is, but I sent an email to MM asking them the max flow that could go through the valve assembly and I think it was what is advertised on their spec sheet, so 3.5 gpm. That means to get the full 4.5 gpm of flow from an aftermarket pump system you would have to upgrade the valve assembly of the winch as well...

I'll try to find some time in the next month or two to put that data together... It is more purdy on a graph.

Any word on putting up the data? I'm interested as well in these winches. I was wondering if a "snow plow" version of the Dodge Dakota steering pump would work. Anybody know?

Thanks for the reminder. I made a new thread for the data:
