Title (EN) EXTRA LIFT MAST FOR LIFT TRUCKS
(FR) MAT DE LEVAGE SUPPLEMENTAIRE POUR VEHICULE ELEVATEUR
Abstract: front page image
(EN)Free-lift of a lift truck carriage is desirable without extension of the uprights, along with the capability to extend the carriage above the uprights, all while retaining clear forward vision and a rigid mast structure. Herein, relatively movable mast members (14a 14b) are shorter than relatively fixed mast members (12a, 12b), the sheaves (28a, 28b) are affixed to the movable members (14a, 14b), the chains (30a, 30b) are attached to the carriage (16) over the sheaves (28a, 28b) and to the relatively fixed members (12a, 12b), while the jacks (24a, 24b) act between the relatively fixed (12a, 12b) and movable (14a, 14a) members. Slide bars (44a, 44b) are movably mounted to the relatively movable members (14a, 14b) and to the carriage (16). A structure (50) is provided for preventing further linear movement of the slide bars (44a, 44b) relative to the relatively movable mast members (14a, 14b) white allowing further linear movement of the carriage (16) relative to the slide bars (44a, 44b), as the jacks (24a, 24b) extending beyond a selected length.
(FR)L"elevation libre d"un chariot d"un vehicule elevateur est souhaitable sans l"extension des montants, ainsi qu"il est souhaitable de pouvoir amener le chariot au-dessus des montants, tout en conservant une bonne vision et une structure de la mature rigide. Des elements de mat relativement mobiles (14a, 14b) sont plus courts que des elements de mat relativement fixes (12a, 12b), les rouets (28a, 28b) sont fixes aux elements mobiles (14a, 14b), les chaines (30a, 30b) sont attachees au chariot (16) par dessus es rouets (28a, 28b) et aux elements relativement fixes (12a, 12b), tandis que les verins (24a, 24b) agissent entre les organes relativement fixes (12a, 12b) et les organes relativement mobiles (14a, 14b). Des barres coulissantes (44a, 44b) sont montees de maniere mobile sur les elements relativement mobiles (14a, 14b) et sur le chariot (16). Une structure (50) est prevue pour empecher le mouvement lineaire supplementaire des barres coulissantes (44a, 44b) par rapport aux elements de mat relativement mobiles (14a, 14b) tout en permettant un mouvement lineaire supplementaire du chariot (16) par rapport aux barres coulissantes (44a, 44b), lorsque les verins (24a, 24b) s"etendent au-dela d"une longueur determinee.
