The technique I have used with audio recorders, ( probably not
as heavy as computer equipment,) is to lay the rack on its back, install
the equipment, round up muscular friends and stand the rack up.
If you've ever seen a rack with three RA81 drives in it, you wouldn't
suggest that method - they are well over 100lbs each, IIRC.
Unfortunately, most of the big stuff I load into racks (BA-11s, RL02s,
RA-81s) does involve using a couple of muscular friends. Little stuff
like BA-23s, RX02s, PDP-8/a boxes, etc., I do myself. There is no way
I could do an RA-81 by myself. If I absolutely had to, I'd probably find
a table that was nearly the same height, but a wee bit shorter, then
shim it up on lumber or something similar until the rails lined up, then
extend the rails and fasten it on from there.
I think the heaviest thing I put in a rack by myself was a PDP-8/i I'd
removed to get the rack up to my bedroom when I was in high school. Since
it's so low in the rack and the rails are so large, I remember balancing
it on my foot to lift it up the few inches it needed. Still took several
tries to line it all up. Moving the rack by myself was a treat - nearly
killed me... I stood *in* the H-960, with my feet sticking out the square
hole for cable access, then hopped it up the stairs one-at-a-time. It
almost fell over twice with me in it. I do *not* recommend anyone else
try it.
I typically just lift the stuff into the rack myself, even the heavy stuff
(like RK05s and the like). Most of the peripherals have a rail that can
be mounted first, and then it is just a matter of lifting the unit up and
sliding it onto the rails. The RL02s have a very nice system for doing this
where the drive is actually set onto the rails and the rail interlocks into
the drive so that the screws can be installed.
I carried a H960 rack up the stairs to my 2nd floor office as well, but I
stood inside of the rack with the rack on its side. I guess I might have a
wider staircase than Ethan does...
In any case, I am a fairly large person, so carrying and lifting these
things is not as much of a problem.
