Systainer Weight Limits?

[smorgasbord]

I'm the proud owner of a Domino XL Set with both systainers of dominos (the 8/10 and 12/14). So, I've got three systainers.

Is it a bad idea to clip them together to move around in the shop? I was surprised to see that they really only clip in the front, and rely on vertical walls in the rear to prevent them from "tipping" apart. OK, I do see that there are protrusions in the rear bottom of the top unit that slide under a lip in the top of the bottom unit. But still, I wonder about that front attachment carrying all that weight.

I would not carry them as a unit outside the shop, like to a job site, since that's too heavy for me, but within the shop to bring them to my workbench? I mean, it's not like it's a big deal to bring them separately, but I am interested in capacity limits.

What I was thinking is that I'd put the two domino assortments on the bottom and the big, heavy, systainer with the XL itself on top. That way the first connector is really only carrying the two assortments, which should be fine as long as the top handle of the top systainer will hold up.

The setup reminds me of the old Hyatt Regency hotel walkway failure in 1981. The original design was a single long threaded rod through which each floor of the skyway passed and was attached. On-site fabricators and engineers modified the design to have multiple shorter rods that simply connected each floor to the floor above. That was fatal (literally) since the modified design had the top skyway nuts carrying not just the weight of that skyway, but also the weight of the skyways below it.

Anyway, I haven't come across any Festool official guidelines for systainer chaining limits, but if there are, I'd like to see them.

The Systainer that my Domino 700XL lives in is the one container I have on an older Festool Systainer dolly. So while I believe that the connections involved with two additional Domino media sets would likely hold the weight of carrying the stack around, this is one case (pardon the expression) that I'm glad I have the dolly. It's a heavy stack, especially if the media Systainers are stuffed. (I've moved to buying the Domino stock in the 750mm sticks, honestly, so the media Systainers now only have limited left-overs, etc.)

Thanks for the reminder of the dollies. Where I'm stacking these systainers now I don't have enough vertical height to add a dolly, but I really only need to slide them out a couple of feet to clear the workbench they're under. I just CNC'd a piece of 12mm Baltic Birch Ply with holes for the feet on top and added 4 thin plastic outdoor furniture sliders on bottom.  The systainers don't click into the plywood, but there's no side-to-side play with the cut-outs so it works just fine.

I have another systainer or two coming, so I'll need to find other places to store things, but this works for now.
