Novelty: hydraulic elevator for cars and merchandises. Constitution: the platform 1 of rectangular, in general, cross section, which platform can be hoisted with the assistance of an arrangement consisted of a single pair of platform-propping and -hoisting elements set in X or V arrangement and a platform-retaining system (4a,4b,5a,5b, 6a,6b,7a,7b,8a,8b, 9a,9b). The pair of the platform-propping and -hoisting elements can alternately be: 1) two hydraulic pistons (2b,2c) fixed with articulated connections (3a,3b) on the ground at a certain mutual distance (X arrangement) or at zero mutual distance (V arrangement) and with articulated connections (3c,3d) on the underside of the platform or; 2) a single pair of two jointly interconnected metal arms (10a,10b) disposed in X- arrangement and assisted for being hoisted by the hydraulic piston 2a; the four ends of the foregoing metal arms end with four wheels (12a,12b,12c,12d) able to roll on the ground surface, on the floor surface and on the underside of the platform too. The platform-retaining system is composed of two perpendicular columns (5a,5b) operating also as guides retaining the platform with the assistance of arrangements of rolling wheels (6a,6b,7a,7b,8a,8b,9a,9b). The driving of the platform onto the perpendicularly-disposed columns (4a,4b) is achieved with the assistance of two vertical stems (4a,4b) firmly adapted proximal to the two angles of the rectangular hoisting platform on which angles there are adapted the arrangements of the rolling wheels. |
