I'm building a project and I need to lift and hold a small box (8x15x40" holding 50-90 lbs) 14 inches, and then retract it with control. I'm thinking of using drawer runners on each side (to guide) and a central lead screw + motor (to power).
Any engineers out there to advise me / tell me I'm crazy and I should use foo technology instead?
I'm wondering what kind of screw to use, what power motor (I think AC would be better for my purposes, but I suppose I could include an adapter), what setup (motor directly connected to the screw?). Any other advices would help too -- I'm not an engineer.
