    Winch - Hydraulic Vs. Electric

    Posted by Jeff on Wednesday, March 18, 2009 @ 06:52 PM  

    For the regular off-roaders, winch users and/or engineer types out there, I'm curious as to your thoughts on hydraulic vs electric winches. The hydraulic models seem to be more popular for heavy-duty applications (military and tow vehicles), whereas the electric models seem to be more popular among the hobbyists and off-roading community. After quite a bit of reading I'm really leaning towards hydraulic but I'm very unfamiliar with winches in real-world applications so I'm looking for some insight from those of you who have used them.

    REMOVABLE vs STATIONARY

    Pros:

    • Reduced vehicle weight when removed and stored
    • Reduced wear and tear on front suspension components when removed
    • Improved fuel mileage when removed
    • Portable winches can be used on front or rear of multiple vehicles
    • Reduced wear and corrosion on winch while in storage
    • Easier to perform winch maintenance tasks when removed

    Cons:

    • Winch is only as strong as the receiver in which it is mounted
    • Hydraulic winches, in particular, don't appear to be easily removed
    • Portable winch requires a hitch receiver

    If at all possible, I would prefer to make use of a portable winch assembly since the FJ is, first and foremost, a daily commuter vehicle. The potential downfall to a portable solution is that the Cruiser weighs as much as the receiver rating, approximately 5000lbs. I've been reading up on snatch blocks and recovery scenarios but I'm still pretty fuzzy on adjusting and reducing the winch load. Is a portable solution even feasible for a 5000lb vehicle or am I wasting my time?

    STEEL vs SYNTHETIC

    As though the winch type debate wasn't enough for you, if anyone has opinions on steel cable vs synthetic, I'd be interested in any feedback on that as well. From a safety factor it sounds like synthetic is the best option but my choices may be limited based on the type of winch as well. Is synthetic fully compatible with both types of winches?

    ODDS and ENDS

    Out of curiosity, are there any types of small electrical motors available that could power the hydraulics in the event that your vehicle was not start-able? Also, I know some of you will probably have preferences for a particular brand of hardware. Because I have no personal experiences with winch manufacturers, I'm interested in hearing about your experiences (good and bad) with particular brands.

    Below is some basic info I've picked up so far but my resources aren't always that reliable so please feel free to correct me if any of the information is misleading or incorrect. I'm new to a lot of this stuff so I'm hoping the more experienced folks can provide info to fill in some of the gaps. Here is what I have so far:

    HYDRAULIC WINCH

    Pros:

    • Less expensive than electric alternatives
    • Will operate under load for long periods without overheating
    • Will operate under water
    • Runs on existing electrical system (no dual battery, high output alt, etc)
    • No significant electrical draw

    Cons:

    • Requires engine to be running
    • Slower spool and pull speed than electric
    • More complicated to assemble
    • Prone to fluid leaks
    • Cannot be easily removed once installed


    ELECTRIC WINCH

    Pros:

    • Does not require engine to be running
    • Faster spooling and pull speed than hydraulic (when in operation)
    • Quicker and easier to install
    • Portable / Removable

    Cons:

    • More expensive than hydraulic options
    • Excessive down time (~1/10 time operational) due to overheating
    • Recommend additional components (dual battery, high output alt, etc)
    • Huge electrical draw - can easily drain battery under high loads

    You probably know more aout winches than I do after your research, so consider these ideas as coming if not from the blind, at least the barely sighted.

    It seems to me that the power of the hydraulic winch would be dependent on the power of the hydraulic pump and could in theory be far more powerful than any 12 volt winch could ever hope to be. But maybe they don't have applications for vehicles that powerful. Heavy equipment uses hydraulics to lift many tons.

    That said, I wouldn't consider a hydraulic winch for a light application like yours. They are susceptible to leaks and if you snag or puncture a hose, it's all over. You would have to carry hydraulic oil, spare hoses and the tools to install them. If the vehicle was not on its wheels or at to steep an angle for oil pickup, you aren't going to want to run the engine -- so no winch. I thought the electric winches were unbearably slow when I looked at them for Bubba and if the hydraulic is slower ...

    I think I would want the electric winch permanently mounted on the frame rather than in a receiver for the strength issue you mentioned. But keep in mind, a 10,000 lb winch should be able to dead lift that weight and all you need to do is roll or at worst drag that weight. You're probably going to want to run the engine if possible, due to the current draw. The one real plus I see for the portable would be the ability to swap ends if you've gone in nose first. And that ability might tip the scales for me.

    As far as steel vs synthetic, why is synthetic considered safer? Because of less weight if it snaps? I think my overriding consideration would be abrasion resistance dragging across ground, rocks, etc.

    Most of the jeeps I have seen use the 8000 lb. electric. Mike would be the one who could give you expert advice: both knowledge and experience. Unless you are a real offroader a winch is pretty much an expensive decoration. Kind of like the city SUV crowd. I have a Warn 8000 winch on the trailer I haul buildings with. It has been more than adequate for the job. The buildings are 1800 lbs but they do not roll and sometimes they tend to dig in as well. I have a separate battery on the trailer just for the winch and the hydraulic tilt bed. I have only had a battery problem one time after 3-4 deliveries. Apparently the truck was not charging. In reality, the time using the winch is only a matter of seconds. While it is a heavy draw it is only for s short time. As far as speed it seems fast enough for me in my application. I suspect Dave is thinking in terms of pulling logs a fair distance which would be comparatively slow and be a large draw down on the battery. I currently have several broken strands in the 5/16 cable which can happen when the cable does not wind up evenly and crosses over. I have a synthetic line replacement on standby. As I recall it was about 3x the price. It is lighter weight for a 10,000 lb rating and there is no recoil if it breaks. The downside is that it is not nearly as abrasion resistant. If I were to do it again I would use cable. It seems to last forever and is much cheaper. The problems with hydraulics seem to be a real drawback.

    A rear receiver mount would have an advantage but if you want to cover all possibilities get a tank and a tank retriever.Big Grin

    In reality you will be with other off roaders who have winches or tow straps and can always give you a pull. Yes, it is harder on the ego to be pulled out, but you will have many opportunities to return the favor. On the other hand if you seriously think you need a winch, better give up the idea of a family driver and think more in terms of being an off road mechanic. I have seen some of the jeeps that come for the annual jeep jamboree at the Nile. They have serious repairs on a frequent basis. Again, I recommend talking to Mike. He's been there and done that.

    Hi Jeff.

    Great questions, I am in agreement with Dave & your dad. I am going to cast my vote for the electric winch (Warn)with a upgraded electrical system.

    You will want good dual batteries ( I run odysseys), with 2 aught fine strand welding cables,and a good battery manager system. (The system i use allows me to winch with both batteries if i need to, or can be isolated to preserve one battery for back up. all controlled by a switch on my dash. They have some nice systems that will automatically divert power and manage your batteries, but i wanted to be able to manually control my system, just my preferance).Also add a high out put alternator that makes a lot of amps.200 amps total would be nice with at least 100 amps at idle (at least 100 amps with a 100% duty cycle @ 600-1000 rpm,preferably more).

    It's been my experience while jeeping with a few guys with hydraulic winches that they do fine with light pulls (although incredibly slow).Where i feel they fall short is on real tough long pulls. although they are strong,I have seen them get the power steering pump so hot that it breaks down the hydraulic fluid and smokes the pump, Now you are left with no steering or winch. I realize this can be overcome with a dedicated H.O. pump & reservoir, but it's my understanding it is costly and complicated, (bracketry & plumbing plus finding room under the hood for every thing). also remember as was stated earlier if you roll over,or you become disabled/ engine does not run you have no winch. I have been on some really dificult trails where every one was winching at the same time and it sure is nice when every one is similarly equipped,one slow winch can really cause a traffic jam.

    Which line to use? Again i have to say galvanized steel air craft cable,properly sized for the winch you choose. I purchase mine @ tacoma wire rope supply and the last 2 I bought cost me .32 cents @ foot x 150' =$48, (5/16th" domestic cable and they will swedge an eye on one end also).Look local to you for a similar company. It is lots cheaper than synthetic, and properly cared for should last indefinately. Here in the northwest our trails are so rocky, steep, & off camber that our lines are frequently being abraded or being pulled over or around an obstacle. There is something unnerving to me about trusting mine & my families lives to a line that you can cut in two with one quick slice from a sharp knife.(especially under tremendous tension), although you can use a sleeve over synthetic line,some times it will not be enough.

    You do have to take care to properly spool your cable on your drum, (both while you are winching and when you are done with your extraction and are respooling. One of the biggest causes of kinked & frayed line is hard winching over loosely spooled line.ALWAYS respool under moderate tension,even if it's only a buddy leaning back on the line, and try to wrap uniformly,also invest in a good pair of HEAVY leather gloves.

    And please use a safety hook with spring latch,or even better, a screw pin shackle on the end of the line to attach to your anchor point. I had to go to a friends funeral who died when his line came loose from his anchorage point because he was helping his winch by driving a little, well he got a little traction and over ran his winch line causing it to slacken and the hook to come loose and then he lost traction and his brakes wouldn't hold him,( extremely steep and loose mountainside). ending in multiple rolls and Kens death. very sad and preventable.

    A receiver mounted winch would be handy at times, but i think you would be better served with a well built winch mount, tied in as low as practicle & to the frame if possible. You will find out that some times you will want to pull at an angle, ie: to break the suction of a deep mud hole and lift your tires and frame clear of the ruts (your winch will thank you) or to right a roll over etc, and a receiver style mount does not like to be pulled to the side. Also the few receiver mounts i have seen add to your approach/departure angles. Usually someone is there to snatch you backwards if you need to be freed from behind.

    Just my .02
    Mike.

    P.S.
    All my winches (3) are WARN 8274 uprights. imo the best winch out there. They dont lend themselves to every rig though, so i'm not sure of your application. I have heard a lot of good about the warn 9500xp. just sayin...

    Just wanted to say thanks to all of you for some very good feedback. Based on what I was reading (prior to your feedback), the hydraulic winches seemed like the way to go. But after seeing your recommendations and reasoning behind using electric winches, I think I'm beginning to understand why there are so many more electric models available.

    (A reply to comment #4)

    I found a similar debate on the FJ Cruiser forums that has a lot of good info so I figured I'd revive this post and see if any of the opinions changed. Here's the link in case anyone is interested in some light reading:

    More Electric vs Hydraulic Fun

    To be honest, I'm still not convinced that electric is the way to go. It does appear to be a simpler setup which would make trail repairs potentially easier. And I already have the secondary deep cycle battery system in place so installation would no doubt be a breeze with the electric.

    As far as hydraulic goes, the H12 Type R seems to be a lot faster than previous revisions and if I were to invest in a 12v auxiliary hydraulic pump and cooler/tank the hydraulic system seems like it would be far superior. Granted your pump is still reliant on electric but at least it would run with the engine off.

    I'm still debating on portable vs permanent too. For a daily commuter it seems wasteful to haul the extra weight of a winch around and exposure to weather elements means unnecessary wear and tear too. Plus a receiver mount on the front of the FJ would give me additional capabilities like maneuvering trailers and hauling small items on a receiver basket. Permanent mount, OTOH, would mean greater approach angle and greater reinforcement when pulling. Then again, as long as there are trees available nearby, one or more snatch blocks can serve to change the pulling angle and help reduce the overall load.

    Don't mind me. I'm just thinking out loud. Enjoy the forum debate and feel free to add any follow-up comments if you like. In the mean time I'll go back to debating for another three years until I finally make a decision. Confused
