I was in the excavating business for most of my life. When I bought my first four post lift I assembled it by myself in about 6 hours using a mini excavator as was mentioned. When I sold it 3 guys came and disassembled it and hauled it away without any kind of lifting equipment. I also recently helped my brother assemble his new one. Four of us with a cherry picker assembled it in about 4 hours. Seems there are multiple means of doing any project, it just depends on what you have access to. Jazzman, I am in Gilbert and my brother is in Chandler. If you make a deal and we can be of any help send me a PM. I'm not on here on a daily basis but will keep my eye out.
