The esest lift is the chain path lift. But because it is so simular than the chain lift i think you won'nt build it. You could build the mill lift, but it uses quite a lot of yellow geers on such a hight. If you rather like somthig turning you should use a lardge rotating arme lift. Of course you could also use a alternative chain lift, but it is again simular to the chain lift. You could also try to invent a lift at your one. If you like more lifts than one you could try to power many lifts with one and the same motor. I hope I could be helpful.
