I want to rehabilitate a 20 ton shop press with screwed up hydraulics.
The local shop equipment store offers the 20-ton low-profile jack shown below. On the packaging one can see they brag this jack can be used horizontally, angled or vertical (the 20-ton standard-profile jack offers no such versatility.)
It would suit me just fine if I could bolt this jack UPSIDE DOWN to the upper crossmember on my press.
What are the chances this will be successful? I'd like the odds to be in my favour before spending $84.99+tax to find our for sure.
It doesn't say upside down does it? Probably because it won't pick up oil for the pump in that direction and won't work. If you're thinking of making a press you'll need a hydraulic cylinder and a separate pump/oil res. like a Porta Power set-up has.
Look at Harbor Freight. The 20 to press is &199.99 US and the bottle jack is right side up.
I'll guarantee you it will not work upside down. Dave in Bellingham,WA
Thanks everyone. Dave, much as I expected.
This forum is such a great community!
Harbor Freight also sell a 20 ton air over hydraulic cyl that works great in any 20 ton press and it goes right in in an upright position
I have 1 similar that works sideways.I have used it to push out a chassis rail 1 time. No upside down that I know of.
I just wish i could replace the jack on my lawnmower lift. It has a threaded hole in the bottom to hold it to the frame and none of the jacks I look at have a threaded hole in the bottom.
Mack, can you drill a hole and tap it?
