ABSTRACT:
A lift system for effecting a vertical parallel movement of a platform relative to a base, in particular for moving a sample changer platform of a sample changer in a weighing system, has at least three substantially identical and mutually interchangeable mechanical lift units supporting the platform. The lift units occupy an at least triangular flexible layout on the base. The lift system is equipped with a drive system that includes a transmission device and a drive element, wherein the transmission device connects the lift units among each other and to the drive element. The arrangement produces a simultaneous vertical movement of the lift units with the platform always staying aligned in a plane that is substantially orthogonal to the gravity force.
