vertical actuator

edited April 2012 in Technology
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.

    Just purchase an electric linear actuator.

    Except those are money & I'm intending to eventually make multiples. And if I'm going to sell this thing, I'd prefer to not spend a disproportionate amount of money on that aspect.

    Perhaps you should define all of your constraints when asking the original question :P

    Have you considered using some manner of hydraulics instead?

    have considered, but don't know enough about it. (that is to say, if you *do* know, please educate me.)

    was considering gas-cylinder assists as well. it is important that it does not require much exertion on the part of the user.

    You know, the ID dept here is *really* into service design. Maybe I should start a handy-stripper company with something in the tag line referencing "heavy lifting".

    Is your project allowed to start with a 50-90 lb weight 14 inches in the air attached to a lever? Because I always recommend a good counterweight.

    if i understand your question, no, unfortunately. this needs to essentially be a small table lift, without being nearly as complex. think those hidden TV cabinets.
