Adding a table lift to a hydraulic press

- My 30 ton hydraulic press was a pretty good piece of kit out of the box but it had one bad design feature. In this video I talk about the problem and what I did to fix it, along with some other improvements.
Nice mod Alan. I also have one of these 30 ton presses and I think I'll also put a winch on the side. Nice work..
Thank you.
Same press I use at work on occasion, one of the engineers did a very similar winch installation when it was installed. Definitely necessary.
Very nice work Alan. I like that the table moves quite fast as you crank the winch.
Thanks Allen. This modification has proved to be one of my best tool improvements and continues to operate really well.
Cheers.
Nice job
A great price of engineering great way to move the table 😃
Thank you Ronald. That project has been a great success and changed a risky chore into an easy adjustment. You might note from another video that I also made a 1" thick table plate for the press. That has also been really useful but wouldn't have been feasible without the hoist.
Cheers, Alan.
I just bought this 30 ton press and you’re right about the table being a pain to raise or lower. Not sure whether I want to go to the lengths you have as I only plan to push in some bushes but depends on what other projects come to it later. I bought that press brake attachment too and that’s going to be useful for bending stuff later. Great job on the pulley system, very inventive.
You'll likely use the press more if its easy to set the table height. I use mine quite often, including for light jobs I used to do with a hammer or the vise. My latest video is an example: th-cam.com/video/cC-Gcaz2TBE/w-d-xo.htmlsi=RzTU9xmrjQ2QtdPK&t=1954 You might also be interested in the 1" plate table I made for the press: th-cam.com/video/XEmGwf6WpX8/w-d-xo.htmlsi=5gf9UDfVNb3wzrZq
Thanks for your comment.
@@alanshomeworkshop No doubt if it were less troublesome to adjust it would be ay more useful, I see a few channels have added something similar so it's definitely an improvement people seek. By the way, the two pieces that you can use as a V block or flat, have you ever found them separating if you try to bend something between the V's? I can imagine them shooting apart when a piece begins to go beyond horizontal. Wondering if I should put something either side to keep them centered.
I have yet to use the V blocks but I think your concern is valid. I wouldn't rely on friction to completely stop them moving, but I can't see them flying apart in a hazardous way.
Alan -- very clever -- two thumbs up .
Thank you.
Good information Alan. Now I know how to do this improvement easily on my press for the same reasons. Thanks, just subscribed. Tony
Tony, pleasing to hear my video helped you. This mod. changed a difficult and risky chore into a simple and safe procedure. I should have done it sooner 🙂 Thanks for subscribing and I hope you also find some of my other videos helpful. Cheers, Alan.
Nice job Alan, well thought out and nicely executed. I have the same press and struggle when moving the table. I'm going to copy what you have done. Can I ask you where you sourced the pulleys and what size are they? Thanks for your channel.
Best regards from South Gippsland, Victoria.
The pulleys are cast iron and were sold as rope sheaves ~3" diameter with 3/8" rope groove. There is no inserted bearing and, as bought, the pulley runs on a 12mm steel pin supported between side plate straps pressed into a "Z" pattern. I would have bought them from ePay, but the only listing I could see today was from a US seller with expensive shipping.
Thanks for watching and good luck with your project - it'll transform the press and make it much easier and safer to use.
Cheers.
PS: the winch and cable came from Bunnings
Some nice mods Alan. I have the same press imported by a company to the UK , so basically different paint work and manual but footpump. I love it but the table is awkward hence searching and finding your video. Very neat solutions. That's a like and subscribe from me.
Thank you - and perhaps you'd be interested in a further improvement: th-cam.com/video/XEmGwf6WpX8/w-d-xo.html
BTW the plate has stayed on since I first put it in place, so the effort was worthwhile for my situation.
Cheers, Alan.
Nice press and a good modification. The cable being in the middle of the long-item pass through space isn’t a good thing for my use. Could the pulleys be moved to the back or front?
I understand your point but, in my usage, this inconvenience is an acceptable price to pay for the benefit. On the rare occasions that I have needed long access through the sides of the press, I set the table at the required height and unhooked the ends of the cable from it after releasing the tension. I'm not sure how well the mechanism would operate with the pulleys moved to the front or the back as the resulting imbalance would cause the table to roll over when lifted and drag on the side frames of the press. However if it was possible to move one side forwards and the other backwards, balance would be retained and I'd be interested to see the result if you manage to do this. Cheers, Alan.
