Bowed out old Dake 25-H press

[RichTes]

Older model, low serial number.

The table sits on top of the pins. Pins don't go through the table holes since it’s a little bowed out.

is there any way to pull the frame sides in? That would be best. I’m going to pull the head off to replace some seals but the only person with a 50 ton press I know doesn’t have a lot of clearance around.

Any other way to correct?

Thanks

Chain binder?

Porta power?

Skidsteer, loader tractor, telehandler? I need a picture to see what we're dealing with here , but that's what I use when I can't fit something in the press.

Either you have the wrong pins that are too short or its not bowed out just a little. The pins should stick out at least 2 or 3 inches.

Its not uncommon for pins to be damaged and possible the previous owner replaced them with pins too short?

Are you sure its even a Dake 25H? The have C channel vertical frame members and if the flanges with the holes are splayed out how does the table even move up and down ????? Do you have a picture because this is not making sense.

One can see how far out the pins stick even past the edges of the table.

I don't think they're saying the flanges of the channel are bowed I think they're saying the uprights are bowed, which changes the distance between the holes relative to the table. Like so:

How would that happen?

Pressing with high forces will naturally straighten them out not bend them?

But if that is the case wrap a sufficient size chain around it with wood blocks between the chain and uprights and use a ratcheting screw type load binder to pull it in.

Is the top member bent up which has pulled in the top of the uprights? Or the top frame bolts loose?

Thanks all. The frame sides are bowed out so the pins won’t fit through the holes.

Theres no pic since while I wait for the seals (evidently Dake is moving warehouses) stuff got piled in front of it.

Pushing out would seem easier than pulling in. I didn’t know a chain binder would generate enough pull. If it’s short enough there’s always the double acting cylinder on my drop deck trailer.

This type of a chain binder should generate sufficient force to pull things straighter....use quality chains and watch how they wrap around the corners. I might be tempted to drill a hole thru the center of the uprights and use a load rated shackle/eye bolt with a piece of channel or plate backing it up on the outside vs looping the uprights with chain
