I have the Bendpak MD6XP in a pit and I love it. It came mostly assembled, and all I did was hook up the hydraulics.
It looks like it could be dissembled, but I never tried. Did your lift come with a manual?
When I had my pit put in, I had them cut a trench and I put in 1.5 inch conduit to carry the hydraulic line and 110 volt line for power in the pit. It is great to the have the pump mounted to the wall and out of my way.
I have a piece of 1/2 plywood that covers the pit when lowered and it basically is gone and out of the way and the plywood helps keep the leaves and debris out of the pit.
It was a real challenge to get the lift into the pit. I had a buddy help me and we used long very stout pry bars and straps. Getting it out would be a real challenge.
Try to download the manual for your lift, and good luck!
