Title (EN) LOAD LIFTING CARRIAGE AND MAST ASSEMBLY
(FR) ENSEMBLE DE CHARIOT ET DE MAT DE LEVAGE DE CHARGE
Abstract: front page image
(EN)A carriage and mast assembly (10) including a mast (16) having outer sides (R, L) and a first pair (36, 38) of movable inner uprights and a second pair (20, 22) of fixed outer uprights, a load lifting carriage (12), a pair (48, 50) of free lift cylinders being directly connected to the first pair (36, 38) of uprights and to the load lifting carriage (12), a pair (52, 54) of mast lift cylinders being connected to the first pair (36, 38) of uprights and to the second pair (20, 22) of uprights, each pair (48, 50) (52, 54) of cylinders being disposed at the outer sides (R, L), and a pair (98) of means for communicating fluid between one (50) of the free lift cylinders (48, 50) and one (54) of the mast lift cylinders (52, 54), respectively. The invention relates to load lifting carriage and mast assemblies (10) having a free lift carriage (12). The problems of using lift chains and sheaves to free lift the carriage (12) and operator visibility through the mast (16) are avoided by directly connecting the free lift cylinders (48, 50) to the carriage (12) and mast (16) and disposing these cylinders (48, 50) outside the mast (16).
(FR)Ensemble (10) de chariot et de mat comprenant un mat (16) possedant des cotes exterieurs (R, L) et une premiere paire (36, 38) de montants mobiles interieurs et une deuxieme paire (20, 22) de montants fixes exterieurs, un chariot de levage de charge (12), une paire (48, 50) de cylindres de levage libres connectes directement a la premiere paire (36, 38) de montants et au chariot (12) de levage de charge, une paire (52, 54) de cylindres de levage de mat connectes a la premiere paire (36, 38) de montants et a la deuxieme paire (20, 22) de montants, chaque paire (48, 50) (52, 54) de cylindres etant disposee sur les cotes exterieurs (R, L), et une paire (98) de moyens servant a mettre en communication le fluide entre un (50) des cylindres (48, 50) de levage libres et un (54) des cylindres (52, 54) de levage de mat, respectivement. La presente invention concerne des ensembles (10) de chariots et de mats de levage de charge possedant un chariot (12) de levage libre. Les problemes causes par l"utilisation de chaines de levage et de rea pour lever librement le chariot (12) ainsi que les problemes de visibilite de l"operateur au travers du mat (16) sont supprimes en connectant directement les cylindres de levage libres (48, 50) au chariot (12) et au mat (16) et en disposant ces cylindres (48, 50) a l"exterieur du mat (16).
