As per the "Today I acquired" thread, I bought a second hand hydraulic power pack, because it looked well engineered, the price was right and it was 10 mile away. There wasn't much info on it, all I know is that it came of a scissor lift and the seller had wanted it to make a lift for his bike but never got around to it.
Just a quick note about YouTube, please refrain from posting endless links to other people's hydraulic press projects unless directly related to the conversation, in which case state when in the vid the related bit happens. I am completely capable of using the YouTube search facility and watching some redneck play crap music while dragging a 2 minute video out to 40 minutes on my own If only all video's were as good as @doubleboost
As the power pack was bought opportunistically, I will need to work within its limitations, but my demands are not great so should be fine. The plan is to get the power pack working before looking at the ironwork and ram. Here's what I know at the moment.
Here's an overview of the pack, there's the tank on the left, motor on the right, connected to the pump, to the right of the pump is a valve and at the bottom labelled UC60, is the controller.
3 phase power goes to the controller, which controls the motor. They are the bottom most connections. The connection labelled X0 is for the switch gear. The connection labelled X6 is for the hose burst valve. Typically these power packs are used on scissor lifts and descend under their own weight so no need for a double acting ram. I guess the controller may also control a valve to allow the scissor lift to drop or keep it where it is.
The pump seems to be an 80 frame 1hp dual voltage 3 phase 4 pole motor. 1410 rpm @50Hz.
This is the pump, it appears to be an Edmo lift special made by Marzocchi, its dated 2013 so I guess the whole unit could be up to 10 years old, unless its been swapped at some point.
The pump takes oil from the tank and pumps it to this valve via the brass fitting on the left/bottom. Oil is returned to the tank via the top hose bypassing the pump. Oil is fed via the quick release connector at the bottom/front to the tool or whatever. The valve isn't electrically operated, no solenoid as I initially thought.

and one of the pump and valve and how it connects to the tank
Given I know not a lot about hydraulics, my first thoughts are that, at least without modification, it won't drive a double acting ram, so I'll need some kind of return mechanism for the ram, weights or springs etc. and to keep it simple, I'll go that way to begin with.
But first I need to get the pinouts for the UC60 controller, it looks like I will need to contact EdmoLift or their agents for a schematic as there's not much on t'internet. This is about as technical as it gets If anybody has worked on Edmo lifts and could shine a light n it, that would be great.
Cheers
