Hand Winch
Test Report
I recently tested the Mud Mauler and ARB Magnum hand
winches and have some interesting results that you should read before purchasing a hand winch.
This
test started out after I bought a hand winch and broke it the first time I used it trying to recover my lightly loaded Pathfinder from a soft mud bog hole. I then set about trying to see if I was doing the wrong thing, if the winch was OK for the job or if I should have got something else in the first place.
This is my own practical winch
test (unaccredited and almost unbiased).
I take no responsibility or liability for what you want to do with this information or with your winch. Remember
winches don’t have brains but hopefully you do, they are only as safe as you make them. Be bloody careful with
winches for 4WD recovery. Be careful as the (real) rated capacities of some
winches are over-stated in advertising.

Test 1
Mud Mauler
The Mud Mauler was advertised by 4WD Megastores in 4WD magazines as "pulls 4.4 tonnes". It is currently advertised on the following web site www.4wdmegastores.com.au/products_lz2/winches/mud_mauler
Stating “Pulls up to 4.4 tonnes” and “Conforms to Australian/NZ standard”
To be fair, it is also advertised by Big Balls Offroad website www.bigballsoffroad.com/category264_1.htm
Stating: “Mud Mauler Handwinch 3.2t lift 5.0t pull 10m cable” but on the subsequent details page it states “Pulls up to 4.4 tonnes”. I don’t know why the discrepenc.
I purchased the Mud Mauler because of this advertised 4.4 tonn pull rating. It fitted neatly under the passenger
seat with the handle under the back
seat. I carried it on a trip all around southern Australia (WA to SA, Vic and Tas) and despite going through some pretty rough
Vic high country and Tas west coast tracks solo, we never needed it or had a chance to
test it out properly.
Only a few weeks ago, I decided to give it a thorough
test. Yes OK, I got
well and truly stuck on a local track that I knew
well while showing a new chum how to do it (or how not to as the case was). I set up the Mud Mauler for a straight line pull directly forward to a convenient tree. I used the short handle provided with the winch and had only just taken up the slack and started to tension the chain (about 6 strokes of the handle) when the shear-pin (bolt in the handle) snapped with only medium level of exertion. I am only 78kg and the winch has a very short handle so I was surprised to snap the shear bolt in the handle so easily (and surprised to end up sitting on my bum in the dirt).
When the bolt snapped, all the parts were thrown into the dirt and mud including the broken bitts of the bolt, the lower part handle that engages the winching cog and a specially shaped washer(Oh yes they were fun to find in the mud). The slack end of the chain that comes out the bottom of the winch was pulled back up and jammed the chain dolly wheel, before the ratchet lever on the drum could do its thing and hold the chain.
The result:
1. Even if I had been supplied with a spare shear pin/ bolt (which I believe now comes with the winch, sticky taped to the handle) the bolt would have been useless if I could not have found the parts in the mud or worked out how they went back together.
2. As the chain was now jammed back up into the winch under load, replacing the bolt and continuing to winch would have been pointless unless I could move the vehicle to unload the chain (that is where you need a second winch I suppose).
I went back to the
shop where I purchased the winch, they rang the manufacturer and willingly handed the phone over to me. I must admit that the manufacturer, Evercam Transport in Queensland were very helpful. I was informed that the winch has a minimum breaking strain for a static load of 4.4 tonnes, however, it has been tested by them and exerts 1.1 tonnes of pull (not 4.4) when a maximum load of 80kg is applied to the top of the handle.
I was advised that the winch handle length and the mild steel shear bolt were designed in combination to fail at a point where damage would not result to the winch. I was also told that if this was a problem and provided I was sensible, I could replace the bolt with one grade higher (grade 5.5) but not to use a higher tensile bolt or a longer handle. The manufacturer also told me that they had used a Mud Mauler with a longer handle to drag a 4 tonne (approx) container across the workshop floor but it just about buggered the winch. However, he reiterated that the 4.4 T rating is a Minimum Breaking Strain and not a working or pulling load rating.
Test 2
The next
test was done just to compare winching effort and effectiveness between the Mud Mauler, Magnum and a Jack-All high lift jack set up as a winch.
For this I used the steep slope of my driveway and attached each winch in turn via a drag chain to the post of my garage. The vehicle was in neutral, had the hand brake off and a big concrete block placed behind each wheel just in case it rolled back. I also used a small 50mm thick block of wood in front of the right front tyre and rear left to simulate the resistance of winching over something like a small
rock during a recovery.
Mud Mauler
I replaced the shear bolt with the standard grade bolt. Firstly I winched the vehicle up the slope about 1m without the small blocks of wood to go over. The Mud Mauler performed OK but was quite hard work 39 strokes of the handle moved about 1 m but I did not measure it out. Next I put the small 50mm thick wood blocks in front of the tyres and continued. The resistance on the handle was considerably higher and the shear bolt broke after the 8th stroke of the handle, locking the winch and again jamming the chain up under the winch.
Magnum
Setting up was not quite as easy as I had thought. The cable was wired on to the reel and tried to unravel itself as soon as I removed the tie wire. A cable holder that hooks around the outside would be far easier. It also took a considerable effort to activate the jaw release handle so that I could feed the cable in to the winch.
Once I had connected the Magnum I conducted the same
test. It took only about 25 strokes of the handle to cover the same distance but the handle strokes were far longer due to the much longer handle and the resistance about half that of the Mud Mauler. When I put the same small wood blocks in front of the tyres and continued, I winched over them without feeling much increased work load. I put a brick in front of one tyre and winched over it with a bit more effort but still less than for the Mud Mauler without the blocks.
High lift jack set up as a winch
The first problem was connecting this with the standard shackles chain and straps that I have. I had an article from 4WD Monthly April 2001 that showed how to do it. They used High Lift brand jack and attached a 4.7t shackle to the top jaw. Ah, I have Jack-All brand jack that does not have a top jaw so I had to get a smaller shackle to go through the top hole of the jack post. I found that it would only fit a smaller 1.7t shackle not suitable for a recovery situation (but adequate for my driveway
test). NOTE it would be really dumb and unsafe to use a bolt or shackle rated to less than 3.2 tonne WLL in a real recovery situation.
I also found that I needed two drag chains to connect this set up. After borrowing another I connected the haul chain from the vehicle to the lower jaw of the jack with a 3.2t shackle. I took up as much slack in the chain with the grab hook on the chain and proceeded to winch. I had only taken up the remaining chain slack and moved the vehicle by about half a meter before I ran out of travel in the jack. I chocked the wheels, released the chain tension by reversing the jack, took up the chain slack and started again. As I had a lower rated shackle, I did not risk winching over the wood blocks. The effort on the jack handle for each stroke was probably a bit less than for the Magnum winch but the extra effort wasted with stopping every half meter or so was a pain. I think this would be difficult to do safely on a steeper slope in a real recovery. Better for bog holes where you do not have to chock the vehicle to stop it running off down the
hill while taking up on the chain.
The result:
Mud Mauler broke the shear pin/ bolt twice and jammed the chain back up into the winch under load. The effort was far higher than I want to do on a hot day in the bush. Moved the vehicle less than two metres up my driveway in about an hour of stuffing around and hard work. The finish of the winch gears is quite rough and I think this would cause quite a bit of ware during use. It might be OK for a small light 4WD but not even my Pathfinder let alone a bigger vehicle. Take a big supply of spare shear bolts and a strong magnet to find the lost bitts in the dirt each time the thing breaks.
The Mud Mauler is smaller, lighter and far more convenient to store and clean than any cable type winch that I have seen. It is a pity that does not have the mechanical strength to do what it is advertised to do or it could be a formidable bit of gear. Make me a stronger one with better leverage please.
In My opinion Magnum wins hands down for winching ease and distance travelled. The Magnum cable release handle was hard to operate and relock.
The same is true for a Big Haul and other similar versions. The cable outside type reel was not ideal to unwind but easy to roll up except for having to use tie wire to hold in place.
High lift jack works OK for very short distances. I would not use it on a steep slope, only in a bog. It was a bit more effort to set up. Brands of high lift jack with only a small hole in the top are unsafe to use with a smaller than adequate shackle.
My advice is to get a decent brand of hand winch from a reputable store. Even if you only need to use it once it has to work properly and safely.
Other brands of cable hand
winches I looked at
I found only two main types of cable hand winch:
the Turfor and its clones have pressed steel bodies and
the Tugger, Big Haul, Magnum, and clones with a cast alloy body. Both work by a similar system of two setts of jaws that alternate to creep along the cable.
The Turfor (French made) cable winch looks pretty good but is expensive. The 11.5 mm cable and hook look very heavy duty. The Turfor hook looks huge compared to Big Haul, Magnum etc. It is surprisingly only rated to 1.6-tonne WLL but must have a good safety margin. Black Rat, Mean Green and others have cheaper copies that still look reasonable
well made.
The Big Haul, Magnum, Supercheap Auto, MaxiTrac and others all seem to be out of the same mould and probably a copy of an original alloy case winch that I have seen as a Tugger UT16 Wire Rope Winch by PWB Anchor and Nobles ‘N’ series Rig-Mate. All seem to be reasonable but some have better wire rope holder reels, handles and hooks. The Big Haul that I saw in a
shop had a rusty handle (straight out of the box).
The PWB Tugger and Nobles ‘N’ series Rig-Mate looked like they were a different moulding and a bit better made than the others and had a neat rubber insert to keep dirt out of the inner workings of the winch and a chromed handle. The Big Haul, Magnum, Supercheap and MaxiTrac have a neat system of half turns to lock the main front connecting pin in place while the PWB Tugger has an older style but very secure using a locking clip pin.
All the Big Haul, Magnum, Supercheap etc.
winches have similar 11mm cable and a 1.6T rated hook BUT put the hook next to a Turfor 1.6T hook and you will see how much bigger and stronger looking it is. I am not sure how they can be rated the same. I think the Turfor also has 11.5 mm cable. After comparing the Magnum hook with the much bigger Turfor hook I do not intend to use the hook, and have tested that a 3.2-T rated shackle will fit through the cable eye leaving the hook hanging.
One hook that I saw had the WLL
sign removed from the hook, It looked like it was ground off and painted over. I was told by the sales person that it is not rated for lifting so they can not have WLL (Working Load Limit) or LC (Lifting Capacity) on it as that implies it has been tested to a standard. Even though it did have "Complies to Australian Standards" on the Super Cheap Auto box, there was something crossed out with black marker pen on every box “1.6 tonne lifting capacity”.
The Magnum that I have from ARB does look like it is from the same manufacturer as the SuperCheap, Repco MaxiTrac and Big Haul. It was a bit cheaper, has a compliance plate with 1.6Tonne lift and 2.3T pull capacity, the handle is zinc plated and not rusty and the winch is painted a nice shade of dark blue.
