For those of us who don’t have any heavy moving equipment, are there heavy Duty Retractable Casters or Mobile Bases that others could recommend?
I’m expecting a fully assembled MR1 by the end of the year and it would be great if I didn’t need a forklift. I’m not sure my garage would even clear a forklift.
I would be happy to pay Langmuir to have retractable casters as an addon as well.
I’ve used this type before. They come in different sizes and weight capacity.
Yes, I was thinking of something like that - heavy duty ones with at least 500lbs capacity.
It would be amazing if the assembled version came with these as an add-on or something. Also not sure these plate or stem versions would work with the MR-1 feet, all the pictures look like the legs/feet are just a 90 degree sheet metal bend.
looking at this photo, you could machine a plate for each leg for those casters.
Oh! Looks like there might already be threaded levelling feet at the bottom? Maybe I’ll reach out to support to ask about this…
I’m asking Langmuir support for the thread size of those mounts to see if we can replace them…as well as whether Langmuir can install levelling casters at the factory for an additional price. Might be worth the hassle/cost if it means I can just roll the machine off the pallet.
You might take a look at the unboxing videos posted. It comes completely unassembled.
Edit: I forgot you can get it assembled with the full service package.
Yes, I’ll be getting the fully assembled version 
Yeah I ordered mine assembled as well. Looking at the time I have with work, kids and what not, I figured it wouldnt have it assembled until 2024 if I did it myself. Plus I didnt really want to be doing concrete in a barn in the MI winter.
I plan to add leveling casters on it just like holla2040 posted. I use them at work all the time with good results. I figured Id be waiting until I received the machine to sort out just what ones I needed and how to mount them.
Any comments on how smooth the floor needs to be? I have smooth concrete floors in the shop but I have read even small items on the floor can block these sort of casters from rolling.
Of course, you are not supposed to move the machine once it’s levelled and the bed is skimmed, so I guess these are for the once in a blue moon case?
I would love to have the ability to roll the MR-1 out a bit and store it tight against a wall, but I think that may throw off the tolerances - but willing to weld up a super stiff base (like discussed in another thread) and rely on that base, the concrete pour and natural stiffness of the machine to be rigid if the machine is moved and re-leveled. I think it’s worth testing - assemble, skim cut the bed, check with a dial indicator, then roll it out and recheck with the same indicator. I will probably do that 
Cheers,

Machine is to heavy for the legs to accommodate casters. Probably could be done with major reinforcement to machine legs. Needs a skid or something like that to bolt it down too. Just my two cents.
I agree that it’s too heavy for casters based on the lack of support (off axis) and the length of the legs. A frame to close in the base and maintain shape (say a square with a diagonal brace) would be my minimum approach. A way overkill skid would also work
No I would not use the existing legs and bolt on the casters, but I do have some heavy steel (U channel and other bits) left over from some fabrication that could provide a base that would be very torsionally stiff - and the casters/base would run off this frame. These are heavy 1/2" structural steel components. The frame would also facilitate using a pallet jack as well. This is similar to an earlier thread about building a base, and the time to put in a base is before concrete lol.

McMaster Carr has versions of those casters that are rated for 500lbs EACH…so 4 of them would be plenty for carrying the weight of the MR-1…at least according to the specs on the MR-1 website.
I don’t think the question is whether you can find casters that can support the machine.
To me the question is can legs that were designed to support the machines stationary gravity loads support the dynamic and lateral loads that would be induced rolling the machine around the shop on casters.
You better modify it prior to concrete or you won’t be able to bolt on the modified legs.
Once you pour concrete you can’t get to the bolts anymore. I mean forever…
We’ve take the legs off before- the concrete secures the bolts heads from the inside and the nuts can be removed to remove the legs.
I dont quote think thats true. I got a set from CasterHQ.com. pretty much the same kind as above. My plan is to jack up the unit slightly and then detach the small block the current feet are screwed into.
I made sure to order the threaded type and not the plate mount as theres no way for a 2" square to rotate there. I will only need to dre-rill and thread the hole to 12mm and just install them and lower it back down one leg at a time.
I ordered the TP-60S on their site under the “Leveling Casters” submenu if anyone is interested.
This place is WWWAAY better than McMaster as the whole set was less than what you will pay for a single caster with MMC.
Probably what I may have to do as well…although I don’t have the luxury of space or large equipment moving tools like some of the other members here…so jacking up the machine is going to be a challenge for me
