Got a bargain on a old grain trailer last year and am using it to haul manure/gravel with it (only reason I bought it). It was an old truck bed with single duals. Previous owner added another 3 ft or so and another axle with duals (all are 9.00x18). Not pretty but was done pretty well. Currently pintle hook, will convert it to GN when I got some time and $.
Hydraulic system: dual cylinders (each a "triple piston" or"cylinder in cylinder in cylinder", depending who I talk to), connected together with tractor hydraulic line at a T and single connector for power up, hold and gravity down. "Big" Cylinder total length 29", diameter 5". Been using my JD 5010 (pushing it) to power it, but wanting to get/make a portable hydraulic over electric (12V)system to unload it. Portable because I want to use it to lift up hydraulic headers on combines that I am collecting (done with jacks, lifts, holding chains etc. in the middle of nowhere....LOL).
Questions are:min/max operating pressure capability for both applications of the pump (power up, hold, gravity down) and size of reservoir? Is 5 gal enough? If a cyl. were empty, no piston, it would be roughly 570 inch2, about 2.45 gal. Just don't know how to account for the piston/cylinder itself on the 2nd and 3rd stage. Have also option of 4 gal tank if it fits, would be lighter to move around.... How about a small primary tank (1-2 gal) with an axillary tank connected to it for the trailer???
Any thoughts appreciated. Thanks in advance,
