Definitions

  • an electric motors is present, provided with an upstream gear box and longitudinally moving vertical spindles in the pillars.
  • the spindles cooperate with suitable nuts (spindle locks) in the intermediate table.
  • spindle locks suitable nuts
  • the solution does not allow to install a second smaller platform in the free internal space of central column, the rising/lowering movement of the second smaller platform being independent from rising/lowering movement of the first bigger platform.
  • the installation of the second smaller platform is not allowed because the pillars of the second smaller platform would preclude the lowering movement of the of the first bigger platform, said pillars being fixed and not collapsing together with the lowering of the second smaller platform.
  • this solution constitutes an undoubted benefit from the point of view of the static stability in any position, terminal or intermediate position, because the platform (3) is always supported in correspondence of four points corresponding to the ends of the platform (3) and in four points each of which in an intermediate position with respect to two of the four supporting ends.
  • the lifting system (23) of the platform is considered, as known in the art and therefore it will not be disclosed in details, possibly being of the hydraulic type, of the electro-mechanical type with rigid chains, etc.
  • the lifter (1) object of the present invention will include all the necessary elements to ensure the operative safety, as, by way of example only, mechanical standing locking means and antifall mechanical guards able to intervene at any height level of the platform.
