mobile tool base

[phred]

Guys I've got a 45ton shop press that I want to move around so I can get larger pieces in. I mainly use it for pressing bearing and such but occasionally I use it as press break and need more depth than the 12" I have it from the shop wall.
I've searched for mobile tool bases but only found small one. This press is just shy of 600 lbs. Anybody ever build one for something like this. I'm looking for ideas that will have fully retrackable wheel so the press is resting on its feet an not the wheels.

Rockler all terrain mobile base is about as stout as a retail unit is.

I've come up with a design that uses acme screws to raise and lower casters. Its not a complicated solution, but I was just fishing for other ideas to help refine this one.

I'd make the casters fixed and use the screws to raise and lower feet depending on how often you plan to move it

I'd do the opposite. Fix casters, then raise and lower some leveling feet. get some feet that have allen or slotted studs or weld some nuts on the top of the stud, then you can raise/lower the feet with a cordless impact or similar

^^^^^^ these ideas .... I just started last night building a mobile base that has 4 Albion swivel casters and 4 leveling pads that are screwed with 5/8"-11 rod for a 3/4" size Bridgeport style mill that weighs close to 1500 lbs.. The swivel casters will allow me to pivot into tight spots in my garage and the leveling pads will level, stabilize and keep the machine from moving when screwed down. I will have some pictures of it in my garage projects thread probably this weekend.

Mine does not weigh 300# but it does weigh close,to 200#s

For mine I just used 3/4 plywood and attached the casters at the corners under the factory legs

Keep in mind you can put fixed casters in the back and legs in the front and then use a floor jack to move it out when you want it to move

If you put correctly rated casters under it you shouldn't have any problems.
