Mini digger winch

[doobin]

Hi all

 

Looking to equip my 1 1/2 ton digger with a hydraulic winch. Blade seems the obvious place to bolt it to- question is, how big a winch to go for? PTO winches seem to have similar sized blades to the digger- what size should I go for? Got 35 litres a minute flow rate.

 

Seen a nice nine ton winch on ebay but that might be pushing it!

Do you plan to use it for winching stuff towards the blade or dragging the digger out of a hole when you've bogged it ?

Both

 

I appreciate they're nowhere near as fast as a PTO winch but I couldn't find any fast hydraulic winches.

It may be worth looking in a recent Land Rover comic, there are a few teams doing winching competitions with 2-speed hydraulic winches and their vehicles weigh a lot more than your digger! I don't know the origin of the winches they use but they might do what you need. My guess would be around 10000lbs to 12000lbs pulling capacity, is that enough?

you want a speedy hydraulic winch? try a milemarker type R

An electric winch with freespool, hand held remote and 35 mts cable would be the easiest to fit and like you say the blade seems the likely place to put it. With all new you would be looking around £1700.

 

Personally I think hydraulic would be the better long term option and if you find the solution please let us know.

Hydraulic would be by far the cheapest option as you already have the hydraulic supply and an electric winch with such small alternators and batteries would soon run flat.

 

You would just need to put “Y” pieces into the relevant breaker pipes down near kingpin (only if you have a 3 pipe system) so the arm can still work but you wont be able to slue as there are only a limited number of rotary couplings to the undercarriage, the only other way is to terminate the pipes for the blade ram with a double 3 way rotary valve (or double 3 way solenoid valve) fixed on the blade then send 2 pipes to the ram and 2 pipes to the winch, all you would do then is lower the blade in the normal way, move the rotary valve to isolate the blade and supply the winch, then hay-presto the lever for the blade up and down works the winch in and out, also you maintain full function of the arm and the slue, however the winch would need mounting in such a way that when the blade is up or down it doesn’t foul the counterweight, which is easer on a zero tail swing machine than a normal one.

remember to check pressures reqd for operation as flow=speed+ pressure=power

Came across this today, check out page 5 of the Farmi winch brochure. Not quite what I had in mind but close.

true

 

hydraulic HP = flow in L * pressure in Bar / 600 = HP

 

e.g. 35L * 204bar / 600 = 11.9HP

 

BUT most small winch only work on >140bar to <180bar which if on run off the above e.g. then would be >8.16HP to <10.5HP so you would need to spec the right pressure motor to get the best out of a winch for your digger max pressure
