PTO driven hydropump for hydro wincheeee

[AT]

hi all,

gonna try to fit my hydraulic winch with a pto driven Hydraulic pump.. any recommendations on whats a good pump.

driving a td5 defender with a LT230(i think)... i aint a techie person but gonna try and learn

anyone knows whats the spline/teeth on that pto?

some info here: MAXI-DRIVE HYDRAULIC P.T.O. UNIT (http://www.4wdworld.com.au/products/maxidrive/hydraulicunit.htm)
For Land Rover Discovery & Defender models and Range Rover with LT230 Transfer Case

cheers,

I have one fitted to my disco,should be easier on a defender if you are using the ox winch do not use the valve that comes with it also get the right type of valve is important as well

[Bush65]

The maxi-drive pto is made for pumps with an SAE 'A', 2 bolt mounting flange and 9 tooth splined shaft. I believe they now have a pto for larger SAE 'B' mounting.

The gear pumps that Mal sells are made by Cross.

am thinking of maybe an alternative... you guys reckon a electric hydraulic winch is a good choice? just throwing around the idea. :)

Why not splice it into your power steer unit like it is designed for as it will run your winch and ster the veh at the same time with ease ..

Or mount up another power steer pump to run the winch as this would probably cheaperand easier than the pto driven jobbie ..

If i was guna drive a winch off the pto it would be a pto winch like a thomas like the army use

the winch are rated at 1500PSI ..does it mean a typical steering pump can do it. i just wanna run it on an alternate pump then the current one im using.

What should i look out for in the steering pump.. just the PSI or is the flow rate important as well..

[weeds]

my mate has a hydraulic winch fitted to his cruiser, i'm pretty sure he said when its connect using the existing steering pump hoses when you steer while winching the winch slows and in some cases stops until you stop the moving the steering wheel, this wouldn't be an issue as its not as if the steering gets a big workout while winching

[lokka]

Any type of power steer pump should do i know a holden one is good fr about 11000 psi so yep it will be adequate your steer pump on the engin will be capble of running both and you can geta shutoff for it so it bypasses the stering so it only runs the winch ...

dont know why youd want to put the hyd pump on the pto unless you dont already have power steering.....

the powersteeing pump (typically) has a fiar margine of headroom for the job it actually does... splice into it for the winch and your laughing.

If you want to go overboard later,,, in addition to this splice in a smaller hyd pump on a 12v startermotor to use as an emergancy pump, fit it with some one way check valves and you can winch when you dont have the engine turning..


If you choose to go this way I would consider fitting a bigger hyd tank to the system to allow for cooling and to help prolong the life of the oil.

thanks for the input :)

now for a stupid question. have a eletric pump lying around belonging to a friend. it belongs in a saloon car.... i cant find the specs anywhere on the output..

can it work or its better i find a pump that comes off a truck .. even without the specs its still kinda safer to assume it'll work....

and i discover pple are selling electric hydraulic pumps on ebay with reservior.. comes of a lift gate or camper.. not that expensive too..(used) will that work or just using the saloon car pump would be good enough.

ohh the reason why im giving myself headaches is this.. i would like to have best of both worlds

hydraulic winch off steering pump...
when engine is running.. i can winch all day long... but when it dies off.. sometimes it does.. bye bye wincheeee

electric winch..
engine running ... can winch but wont last long if theres a need to winch every 50metres of travel.
and when the engine's dead.. byebye wincheee too cuz amp too high even for a double batt setup(i have that)....

now THE HYBRID

engine running... same deal no problems...
engine's dead.. winching capabilities still available and may last longer then a electric pure breed if i dont go overkill on the electric pump,

these are the reasons why i need help on finding the best possible electric pump to work the winch effectively without too much of an overkill..

I feel like a preschooler asking for help on algebra..:D

i have a 12000lbs hydraulics... my vehicle is about 2 ton.. with me in it.. that makes 2.1tons + shampoos, soap and my 3 square meals a day... thats about 2.2.. if my gal comes along ...its 2.4tons including her sq meals and shmpooo (am glad she isnt reg in this forum) :p guess getting a 12000lbs isnt that far off

doing elec over hydraulic to mechanical is not as effecient as going elec or hydraulic alone.

get a snatch block to make the workload lighter on the winch. (doubles your single line pulll by going to a 2 line pull..

so long as your gont going to drive it to death every day, a small starter out of say a suzuki sierra on a holden powersteering pump should give you plenty of power and not be stupidly hard on the batteries...

This all depends on what your objectives are and how much money you have.
Are you talking about general touring with the occasional mud pool/ rock ledge then just go electric.
The simplest and cheapest winch by far is an electric winch. Set up and maintained will get you out of trouble. Even long extended winching can be done but will need to allow the motor to cool and battery to build back up.
Hydraulics for some are the ultimate for their extended or multiple usage such as challenge. They come at a hugh cost to be effective.
I have an ox hydraulic run on the steering pump. Yes it will winch all day but it is PAINFULLY SLOW. Yes winching should be done nice, slow and with the brain in gear but the power steering pump on the Land Rover is inadequate. If it was an option of electric or hydraulic powered by the LR steering pump, electric will win by a mile for general use.
You said that you had a hydraulic winch. Probably best to go to someone who has it set up such as Maxi Drive engineering. Pumps must be set up for the winch motor. Some of these forces if not done correctly will damage the chassis or mounts. If you have a/c on a Defender for example then due to no more room under the bonnet then a PTO is basically your best option.
A 12v pump is another option but you are best going o a hydraulic specialist for advise re necessary outputs and amp draw.
There are a lot of mathematics involved to set up pumps to motors and logistics eg PTO/fan driven pump/electric pump. See a hydraulic specialist.
