I have the GDR-80-F-NYN casters. My machine easily weighs north of 1200 lbs, and they roll smooth. They did bog down when I tried to roll my machine around PLUS my 150 lb surface plate sitting on it for tramming, so 1200-1300 is probably the practical limit.
The levelling caster assemblies worked but weren’t perfect, especially because there was an incline in the area of my garage where I was putting the machine, so a lot of the weight/load started off on a couple of casters. I definitely saw the sheet metal legs bouncing around a bit. That being said, they worked to get me into position and I’ve now lowered it to rest onto the rubber feet. The important part is that it allowed me to roll into the spot I wanted, as my residential garage didn’t allow me to use the forklift to put it into the exact position without crashing the forklift into the wall/ceiling
The lift gate service was sketchy as hell. The MR1 barely fit onto the lift. For the amount that we paid for shipping, I would have expected a better delivery truck, not just some random furniture moving style truck
One of the handles fell off during transit and one of the doors seems bent or something
The machine comes with some plasma cut cross bracing around the legs and brackets for the fork lift forks. It’s really silly that the cross bracing covers the fork lift bracket holes, because ideally we would have left the cross bracing on until it was fully moved into position and then taken them off, but you have to remove them on the front and back in order to get the forks in
The fork holes on the bracket are really tight/small. There’s a lot of rubbing when the forks go in if you’re not perfectly aligned.
The brackets come with 2x4s in case you need to forklift it up in the other direction. These 2x4s are super short though and only overhang out of the brackets by an inch on each side
I wish that the machine came with some kind of bar or tubing near the bottom so that we could jack the machine up easier in the future with a simple low profile jack
There are ratchet straps that are meant to tie the machine down to the pallet (not shown in pictures) - but they were ripped when we opened the box. I presume these are meant to be tied around the plasma cut fork brackets, but these brackets are super sharp, straight off the plasma and not deburred, so not surprising that they cut/ripped the nylon strapping during transit.
Langmuir really, really needs to provide some kind of documentation on all of this stuff. I had to ask them lots of questions about the crate dimensions, height, fork brackets, etc. to get an idea of how this thing would be moved. We’re a small business run in a residential garage so we don’t have the luxury of space and/or heavy moving equipment, so having some documentation on what we expect and how to move things would have saved us some anxiety. I can imagine for less prepared individuals this would have been a gong show.
Overall a decent experience, but clearly some things that can be improved. I’m now looking forward to unboxing all the bits and slowly setting up the machine
It was good enough to wheel around my shop a small distance, so it did the job. I wouldn’t say that it’s sturdy enough to roll overtop of things or on rougher terrain - a limitation that I think is just because of the sheet metal legs.
Overall though, for what I needed, they worked great.
If I were to do it again though, I would have bought the slightly larger version with larger wheels, load capacity, and a ratcheting levelling mechanism.
I’m just glad I got it off the pallet, in place and in our tiny shop
I ended up keeping all the cross bracing and the rear forklift bracket on the machine. Figure the extra support won’t hurt. I only removed the front forklift bracket as I might try to find a small rolling cabinet or something I can sneak underneath.
In the mean time I’ve unpacked everything and organized the tools. There are several mods I’m planning to do before actually running the machine…specifically:
Y-axis way covers so chips don’t build up all over the lead screws. It looks like the X axis is fairly well protected so I might not bother with these, as way covers can be expensive
Laser cut out acrylic windows for the inside of the doors to prevent chips and coolant from splashing inside the doors
An articulating mount for the touchscreen - the stock arm sticks out stupidly and I don’t have room in our tiny shop for it
Do you find that the feet can rock at all when extended? I bought a ratchet lever set and returned them because when raised there was no locknut and the feet could move a little bit inside the slop of the threads. Maybe higher quality ones are better there?
I also planned to make similar mounting bolts to the ones that you made, and then add some steel bracing on the sides and back to stiffen up the legs. Temporary ones could be installed in front during the move and put away when done to allow access under the machine.
I’d still like to do the upgrade if I can find the right casters.
It seems pretty sturdy right now to be honest but I have yet to cut any chips and see if it’s causing problems.
If I were to do it again, and if I had the ability/skills to weld, I would actually weld a steel threaded block instead of screwing it on. It would make that connection a lot more sturdy when rolling on the floor.
