  I am building a big walker thing. It has a mining laser at the bottom that can be lifted on one half, and the other is attached to the vehicle.
  
  However, I can't seem to find a way, because the hooks attached to the strings come off to easily. The studs are also facing down and I am not using Mindstorms.
  
  I'm looking for a purely LEGO solution.

  Screwjacks!
  
  Key components would be [Technic, Gear Rack 1 x 4](http://www.bricklink.com/catalogItem.asp?P=3743) and [Technic, Gear Worm Screw](http://www.bricklink.com/catalogItem.asp?P=4716)
  
  Application of said parts are left as an exercise for the reader, though since OP says they're not using Technic, this might be a moot answer.
