Runva Hyd winches any good?

[Sitec]

Hello all... I've been looking at Hydraulic winches as I have a truck gearbox with a sizeable dowty pump on the side of it that as some of you will know is going into the 101.... I've been looking at the various s/h winches on Gumtree and Ebay but then stumbled on the 10000lb Runva Hydraulic Winch. I plan to mount it under the floor at the rear of the 101 and figure that 10000lb is plenty because that doubles with a double line pull.... The advert says 'lifetime Guarantee' and at $1350 it has to be a better or comparable option to a tidy S/H Superwinch at $1500.... Your thoughts and opinions would be appreciated be they +VE or -VE. Cheers all. Simon.

So, no one has had anything to do with these?? Kinda tells me that they're no good then! :)

That might not be the case. Maybe most people aren't set up to power a hydraulic winch.

I've got a runva 12v electric 9500lb winch on my disco 2. I've used it twice and it worked very well.

[rangieman]

No not had any experience in the runva , But a mate of mine has a 4x4 w/shop here in vic and he is a authorised agent and repair agent for them , he was a tigerz repairer but got sick of fixing winch.s.
He actualy says they are the best chinese which he has seen and worked on;) He has had very little problems or need to fix on them well the electric ones any way :cool:
If you want pm me and ill send you his contact details and you can ask him your self;)

Mmmm. Maybe I've found a use for that Isuzu PTO drive and pump sitting in my shed ;)

I've just bought a 15,000lb Runva Hyd. winch for my truck (inter ACCO), haven't finished setting up yet but the construction is solid and the accessories supplied seem to be first class, will let you know how it performs in a day or 2.
My biggest problem is setting up the hydraulics off the PTO pump which powers the 5T. Hiab crane, seems I need to setup a relief valve so as I can by-pass the Hiab setup, you will more than likely have to install a relief valve as well, Regards Frank.
P.S. when buying a winch don't go by the advertised 10,000lb cap. go by the SWL of the cable supplied, in the case of the 10K. you will find that the SWL of the cable is around 1T. BTW I paid $1078 for my Runva 15K winch which includes freight of $99.95 weighs 85kgs. if you want the name of the seller reply here or send a PM.

On our Isuzu truck we run a 22000 lb hydraulic winch which runs off a spare spool valve of the crane control.A wing nut holds the lever in the forward or reverse position .Works very well with no other valves needed

[uninformed]

Frank, Since you seem to ALWAYS bring up the cable size VS SWL on winches. Could you tell me #1, are you referring to LIFTING? and #2 are these and any 4x4 winch rated for LIFTING?

Thanks for that advice, I don't have a spare valve on my Hiab, so I'm tapping into the outrigger pipeline with a 3 way valve which will give me the pressure and the use of the Hiab relief valve, Regards Frank.

#1 , NO, #2, No, and the reason I ALWAYS comment is that there are winch sellers out there advertising line pull that is way above the Guaranteed Breaking Strain (GBS) of the cable supplied.
Do you know why these winches are not rated for lifting, I'll bet you have no IDEA why?
I imagine you are thinking there is a different SWL for lifting as opposed to dragging, well your wrong. SWL is just that. A rope/sling/chain/shackle/etc. doesn't know what it is being used for the SWL doesn't change because of use, Regards Frank.

Ok then, how about adding some info like the safe working load of cable sizes provided on winches. How many "times" factor is the SWL above the actual braking strain of cable for lifting?

Lets take for example a 10,000lb winch with the standard 3/8th cable.

Also If I have a 10,000lb winch what size cable should I run to be safe at 10,000lb. Will that cable be happy to wrap around my 70 or so mm dia drum?

A winch advertised at 10000lb, I assume is the max load it will pull or lift with the min. number of wraps on the drum, therefore at it's max. mechanical advantage.
Now if you lay 50lb GBS fishing line on that spool then the max. it will pull is 50lb before it breaks, regardless of the advertised load rating. My point is that a winch is no better than the cable it is supplied with.
If spooled with 3/8" (10mm) galvanised IWRC (7 strand) then the SWL of THAT WIRE ROPE is 1100kg (2420lb) using a Safety Factor of 5 (GP) i.e. SWL= 1/5 of GBS then the GBS should be 5 x SWL, which is 5500kgs.(12100lbs.).
But this way of working out the SWL and GBS is dubious at best, the correct way would be to KNOW the GBS of the rope supplied and then divide that by the SF of 5 for gen. purpose use, to arrive at the SWL.
I have seen winches advertised on eBay of having 13,000lb working capacity supplied with rope that (by it's advertised dia.) was only around 9,000lbs. GBS.
In my whole rigging career I have never seen a winch cable break, yet if I had a dollar for every winch cable snapped in 4WD recovery I would be rich.
BTW you have not asked why, or the difference between a winch built for a 4WD is not rated for lifting, Regards Frank.

[uninformed]

why dont you tell me then :D

[Tank]

OK, the casing on a 4WD winch is designed to be fitted to and supported by a bulbar or in the portable ones a frame. A winch designed as an overhead winch as in a workshop has the casing designed to support itself off a single attachment point, say to a sliding bogey or set of wheels.
But the main reason is that winches used for lifting have travel limit switches to cut power to stop the hook being wound onto the drum and they also have a positive braking system that will not let the drum rotate when the load is suspended, it should be a failsafe system, unlike the simple braking system on a 4WD winch, Regards Frank.

Finally completed installation of new Runva hyd. winch rated at 15,000lb line pull, it is running off the PTO pump through the relief valve on the Hiab crane via the passenger side outrigger ram. I have installed a 2 way ball tap that either directs fluid to the outrigger ram or to the Winch, the winch stats say that running pressure is 1667lbs. psi., hoses supplied are stamped as rated to 2250psi..
Anyway winch runs smoothly, with no noise or vibration, engine on truck running at around 1000 to 1200 rpm. Hauled a Mercedes car (approx.) 2 tonne up a set of ramps and onto the tray (not a Tilt tray) with no effort at all and no heat generated, so far so good, will update if any problems, Regards Frank.

Good to hear! Thanks for the PM too. I'll be watching with interest how it goes after a bit of work, and if all is still good in April/May then a Runva winch can be the winter project! Cheers again! :)

Most common setup uses a CETOP 3/5 (pending o the flow) solenoid spool valve to control the winch. The valve mounting subplate may or may not have a relief in it, if not then a separate relief will be needed. A simple 3 port selector valve is then used to divert pump flow to either the crane valve or winch valve.


If using a spare spool in the crane valve to control the winch, yes you may well need a separate relief (or 2) to limit the pressure to the winch motor.

Thanks anyway (see my post #17) but the system I setup works great, simple and effective, Regards Frank.

[Rick1970]

Just keep an eye on your line pressure. Coming of the leg circuit you are probably going to see full system pressure at the winch motor in a stall situation. Depending on the crane, this would most likely be 2500psi + so your 15,000lb line pull will jump to 22,000+.


Years ago I help setup an old 20,000lb hydraulic Olding winch on a tilt tray, the guy who owned it didn't want to set up a separate system and just ran the winch of a spare spool in the Palfinger crane valve bank.


He changed the circuit later to include a relief set much lower for the winch after a container he was winching on jambed on the container locks and the 16mm wire rope he was using broke and nearly went through the headboard of the tray....

Yeah, I have seen some truly awful looking, but correctly sized, cables on hoisting winches that you would have thought would break, but didn't.


Was called out one day to replace a few bolts on a 5T winch on a crane. Seems they were trying to pull out a power pole with the winch, which stalled.
The crane had been fitted with a load management override button by the manufacturer due to an apparent electrical system design fault. This allowed them to get a bit more pressure on the rope. When that failed to pull the pole, they simple hit the button and luffed up......rope held but it ripped the winch from its mountings on the top of the boom.

Update on 15,000lb Runva Hyd. Winch, no problems found so far, no leaks, though a bit slow compared to an electric winch, 2 speed model may correct that, but it isn't a problem and am happy with it so far, Regards Frank.

The winch fitting and control valve is the easy bit.
The hard work is the fitting of a hydraulic oil tank on the vehicle.
many a time I have had to set up something like this using second hand parts.
If you figure out oil tank location you need largesh oil return hose/pipe with a filter on it and a oil supply to the pump.
I figure you beening in the tractor game should have access to a single spool valve with adjustable relief just like the stuff used on tractor attachments etc.
Cost of hosing and locating the hosing in side the confined area of a 101 chassis would be interesting.
To be very realistic a electric winch will save money, weight , time, effort.
How many times in the real world do you use a winch on a small 4x4 truck.
If you were fitting a winch on the back of a tilt tray I would say go hydraulic because of the fact a full hydraulic system is already in place and the constant usage of the winch.
This is the most cost effective hydraulic filter around, easy, throw away
Toyota 67502 20540 Hydraulic Filter WIX 57111 | eBay (http://www.ebay.com/itm/TOYOTA-67502-20540-Hydraulic-Filter-WIX-57111-/251417100801?pt=BI_Heavy_Equipment_Parts&hash=item3a89a08201)
I suspect the dowty pump fitted to a truck gearbox would be on the large side to run the hydraulic winch shown..........they can run slowly from a power steering pump circult.
Electric winch fitting will save a lot of space.
I found when fitting a LPG tank behind the rear diff of 101 the exhaust and muffler had to be moved.
The new position of the exhaust system made for some interesting exhaust pipe work.
One of the best positions for a electric winch on a 101 is just behind the front bumper between the chassis rails.
Any rearward winching could be done by a simple pulley on the front diff housing.
One other point and I know I will start a can of worms.
In the time I had a cheapo Aldi $350 electric winch I couldn't kill it and I did some bad things to it.
My only complain about the Adli winch was the 25 mtrs cable was too short and a bolt head in the drum would cause damage to the cable.
