Title (EN) LIFTING AND LOWERING DEVICE FOR TILTING A LOADING PLATFORM,PARTICULARLY FOR TRUCKS AND TRAILERS
(FR) DISPOSITIF DE LEVAGE ET D"ABAISSEMENT POUR BASCULER UNE PLATEFORME DE CHARGEMENT, NOTAMMENT POUR CAMIONS ET REMORQUES
Abstract: front page image
(EN)A scissors-like tilting device, e.g., for use on trucks, has a lower lever, hinged to the body of the vehicle and an upper double-arm scissors-lever, hinged to the loading platform, and a hydraulic piston (1, 2) connected between the body of the vehicle and a shaft on the upper lever. The purpose is to obtain a wide tilting angle of the loading platform combined with a large initial lifting force, which has the possibility of exerting at any position of the loading platform a positive backward force on the platform. The solution consists in providing an angled end for the lower scissors-lever (3.3") and a special trapezoidal hinge connection between the scissors-levers (3.3", 4.4") that is formed by connecting links (5.5", 6.6") of different lengths. The arrangement also allows an especially low construction height of the tilting device in its initial position.
(FR)Dispositif de basculement a articulation du type ciseaux, par exemple pour camions, comprend un levier inferieur, articule sur le vehicule et un levier superieur a double bras du type ciseaux, articule sur la plateforme de chargement, et un verin hydraulique (1, 2) dispose entre le vehicule et un axe sur le levier superieur. Le dispositif permet d"obtenir un angle d"inclinaison de la plateforme de chargement tres ouvert tout en conservant une force de levage initiale elevee, et offre la possibilite d"exercer sur la plateforme, quelle que soit sa position, une force de rappel positive. La solution consiste a donner a l"extremite du levier inferieur (3, 3") une forme angulaire et a articuler les leviers (3.3", 4.4") entre eux a l"aide d"une articulation trapezoidale forme par des bras de liaison (5.5", 6.6") de longueurs differentes. Cette disposition permet egalement de limiter considerablement l"encombrement vertical du dispositif dans sa position initiale.
