12v hydraulic pumps

Three 12v hydraulic pumps followed me home.

They are gently used or new old stock, but similar to these:

and include a manual pumping handle in addition to a motorized pump. 2400 PSI.

Having been bitten often by selling stuff that I later needed, I wonder if these have any real life use for my applications.

They can certainly be useful if you want to build yourself any sort of mobile lifting equipment, such as a specialty lift truck for moving larger machines. Keep in mind they are intermittent duty and noisy when considering other applications.

Yes, I hear you. After some bad experience with "air/hydraulic" freezing due to rust and weather exposure, I now prefer all my moving equipment to be manual.

The key thing is to try to park any outdoor hydraulic equipment with the cylinders retracted and thus with the piston rod protected in the oil bath inside. When I had my backhoe I always did this, though it meant parking it with the boom fully extended out on the ground. The few cylinders that couldn't be retracted had the piston rods coated with grease for the winter.

Do you want to set up a H-frame hydraulic press with motorized operation? (Though I'm not sure whether 2400 PSI would be sufficient for those.) I know that the Enerpac hand pumps will get up to 10,000 PSI, and the electric (120 VAC powered) pump for the Amp hydraulic crimpers has a cutoff around 7400 PSI I think.

Also -- you could use them to operate hydraulic fixturing on the CNC mill. 2400 PSI should be plenty for that, I would think. (But really, AC power would be more convenient.)

Hmm ... a powered jack to lift the tongue of your trailer? that would benefit from the 12 VDC operation.

Just some possibilities.

Enjoy, DoN.

DoN, the only thing that comes to my min dis converting my trailer to a dump trailer, which I do not care to do.

Potentially a way to impress the SWMO with a nice set of hydroformed vases...

Your tractor doesn't have hydraulics???

Moblie lift rigs for machines would be nice, but I expect you could make them with regular long travel jacks as used on shop cranes, and save the extra bulk and hassle of hydraulic lines, valves and power packs.

It does, '64 Fordson Super Major / Ford 5000 in USA.

I want self contained hydraulics for the cultivator so I do not have to disconnect the FEL. Much easier to connect a power lead.

I also need to build a road licenced tipper trailer to collect free horse manure from stables about 5 miles away. Current trailer has off road tyres and no brakes or suspension.

How about a simple selector valve to direct the hydraulics?

Gunner is right, useless. I'll take the other two off your hands.

Close. Choose 'drop bed trailer' for a good time.
