Not being a lover of rack-mounted equipment, I'm not the one to do this sort of
thing often, but, when we were setting up the ISP, with dozens of drawers of
5-1/4" disk drives and the associated power supplies to heft into place so they
could be screwed to the frame, we used two fellows with muscle and a third with
a screwdriver and small hands with nimble fingers.
When I worked in the aerospace industry, where the "right" equipment is always
in the wrong place, I frequently observed a technician with a solid plate he'd
made from a piece of heavy steel and a couple of brackets, on which he situated
a pair of small bottle jacks with which he pushed the equipment into place so he
didn't have to get help when he rearranged the hardware in the racks. I found
that fairly clever, though I imagine one still had to have some skill to go with
it.

In some cases the rack can be laid down, the equipment mounted in it,
and then it can (hopefully) be stood upright again... if the rack is heavy
and you are performing this solo, you can tip the rack back against
something so there is less of a 'lift' later.
Depends on the hieght of the rack and the tonnage involved.
Alternatively, you can run in some rack screws under the flange of the
items, then mount them with the normal screws, and remove the first set.
I have also used temporary aluminum rails that the unit could be slid
onto in order to mount it by the flanges.. the rails are then removed for
later re-use.
I have, in the case of big heavy things (>200lb) used jacks and lumber,
but this gets to be quite a production.
