External Hydraulic Pack

[ThreePer]

Does anyone have any ideas or links to anybody making a electicly powered hydraulic pack suitable for on-the-hook/belly operations? Something fairly small and light. Used on a light or intermediate.

 

Thanks in advance.

there are so many variables that we'd need to know to help you narrow down a search.

 

what are you trying to build? what do you need it to do?

[SuddenStop]

ok, i'll let you continue your search on your own.

What do they use for a hydro pack with tree toppers/cone rakes? Something along those lines is what I am after.

[SuddenStop]

The ones I was involved with, had a gas powered motor running the hydraulic pump and ram.

It was a substantial sized ram to get the cutting power, even using mechanical advantages with leverage. The cutter was custom made shear that could cut 6-8". Worked well even though it was on the heavy side.

 

I'll browse around and see what I can find

 

If you're buidling an actual tree topper and if you'd consider it, you should look into a servo actuated electric saw (chainsaw perhaps), I can see an immediate weight savings as well as simplicity in that.

Not building an actual tree topper no but thanks for the info. I realize I am not showing all my cards here so it is tough.

 

We have a gas powered hydraulic pump right now too and I am trying to eliminate it from our project. Too many moving parts and too heavy. My plan was to use something like a snow plow hydraulic pack (but in 24v of course).

 

Princess auto has most of the parts I need, just gotta find a solid 24VDC power pack. I think I have found a few online though.

How about using pressurized air from the compressor?

 

It's been a few years, but I used to work for a company that had a grapple and a cone harvester which used an "hydraulic" ram which operated on air pressure.

 

A C20B makes about 90 psi at 100% torque. Run an airline down the longline, a little accumulator with a checkvalve and you are in business.

 

Of course, that was in the days when STCs were optional.

Haha ya the STC thing scares me a bit. Was hopeing to keep the entire system pickle-able.

Try can am in delta they built us one years ago for a KMAX grapple
