Can I ask how you got the lower TR in there? Did it go in before the upper half of the frame?
And how did you get the upper one in? There doesn't appear to be enough headroom for a forklift, but I could be mistaken.
No forklift used, only an engine hoist (cherry picker in the US). I first placed sleepers on the floor and vertical posts bolted to the back wall. Placed the Doretti so the frame rests on the sleepers. Then placed the front posts and the next set of horizontal runners. The next car was lifted into place using the engine hoist. A TR has four mounting points for the body in the interior. I used those points and two lift chains and a load leveler and then just picked the car up and slid it into place. A TR minus engine, gearbox, interior and most everything else is maybe 1200 pounds. I then built up the structure around the second car the same as the first. The top car was a bit trickier as my hoist would not quite lift high enough. So, I built some runners that came straight out even with the top level but were attached with hinges. Those runners tilted down and were supported with some temporary legs. I built a cradle that would slide along the runners and set the car on the cradle using the hoist. I then used the hoist to lift up the front of the runners until they were parallel with the top of the rack and then used some cables and pulleys and a come-a-long to pull the car and cradle back onto the top shelf. I then unbolted the runners and stashed them. Everything is bolted together with structural screws and reinforcing plates and tied into the walls. The garage was built only three years ago and to the latest building codes which are pretty substantial as this is earthquake country.
I wanted to build a bigger garage, about 1200 sq ft, but my city codes wouldn't allow it. I was allowed 800 sq ft max so I had to get a little creative. My wife said I should just get rid of a couple cars but that made too much sense and we can't have that can we?
