The system comprises a drive assembly fixed along an imaginary longitudinal centre line of a rectangular base and having two identical units. The main platform (56) is lifted and lowered by operating the drive assembly and the guide frame (58) fixed on one end of the base extends at right angles thereto and guides the movement of the main platform. Each unit of the drive assembly can include a swivel console (62) fixed on the base along the imaginary longitudinal line, and a piston arm (66).
