This screw jack is fitted with a large turntable fixed on top of a metric square pitch screw thread.

                                     
  • All items are mounted onto a bench top base.
  • Wrapped around the periphery of the large turntable is a cord, which runs off horizontally and over a pulley, allowing the free end of the cord to hang vertical.
  • A load hanger is attached to the free end of the cord to create the driving torque for the screw jack.
  • Depending on the orientation of the cord on the turntable will determine whether the turntable is raised or lowered.
