Hey, it's not my video but the unit on the left is a hydraulic power pack. It consists of a motor driving a hydraulic pump with two solenoid valves mounted on top and a semi transparent reservoir where you can see the oil level change as the oil is pumped in or out from the cylinders. Hope it helps.
I don't have an exact list at the moment, but the parts are all available from flowfitonline.com - check their catalogue and you should be able to find what you need, even if you then buy some of the parts elsewhere.
