The two 30 foot base pipes are 10 feet in the ground, so pivot point is 20 feet up. It was counterbalanced at the base with a billet shoved inside the bottom 6" pipe. A boat winch cranked it up and down in about three minutes ...my wife could handle it!
Also saw a guyed 60 foot Rohn lattice tower with similar tilting mechanism. I have the engineering print and some pics if anyone is interested: http://s145.photobucket.com/albums/r203/scorman1/Foldover%20tower/
