Hydraulic Power Pack

[Whitetrash]

I decided awhile back I wanted a Hydraulic power pack to run some equipment I plan on building. Press Brake, Picket and Cage maker, Roll bender Etc. Basically whatever needs hydropower. I had my eye on an old Coats tire machine and a shop compressor that I finally picked up for $400.00 Once the build commenced I cannibilized the Coats down to the components I wanted to keep and assembled my power pack Now I've got a 3 horse system with 3 separate hydraulic circuits. Two spools in the valve body are set up to run cylinders and one which ran the mount/dismount arm powered a hydraulic gear motor. I found a picture of the original machine and took some of the finished unit. Because, I wasn't recording things for posterity during the build. So here's the "Skonk Werx Power Pack"

Looks like a useful tool. Got a question... does it matter whether an hydraulic pump is mounted horizontally or vertically?

[Whitetrash]

Yea, it can depending the pump design and bearing setup. Same goes for the electric motor. I kept it the way Coats designed it. They build a good product IMHO.

I built something like yours for a shop I used to work for. The guys called it the "POWER WAGON".

Unless the manufacturer say different, the pump doesn't care if it is mounted vertical. A lot of power packs are made with the whole pump submerged in oil; this is quiter, simplifies plumbing, no priming issues, etc... mark

W'T', great recycling.

Nice rig.

I like it. What kind of pressure are we talking about?

[Whitetrash]

Not sure I haven't thrown a gauge on it and deadheaded it to see when the relief opens yet.

Sooner or later your going to find out. One way or the other.

Digr's question on system pressure got me curious too. So, I checked it today. 1500 lbs. on the nose would be the answer. I also took a picture of the gear and drive motor from the mount/dismount table that I saved to give a better idea what I have in mind for building a Picket/Cage twister and powering a roll bender. The end of the hollow gear shaft is set up for 2" square tube. This will allow me to interchange slide in dies for twisting stock or a shaft to drive the roll bender. I figured my ratio at 9.75 to 1 reduction based on my tooth count. If it doesn't have enough grunt I'll just run it through another reduction box. I also saved all the mount flanges for the gear and shaft complete w/brass bushings. So mounting should be fairly straight forward during fabrication

looks like you will plenty of power.
