Title (EN) CARRIAGE ROLLER ARRANGEMENT FOR A CARRIAGE AND MAST ASSEMBLY
(FR) CHARIOT ROULANT POUR UN ASSEMBLAGE A CHARIOT ET MAT
Abstract: front page image
(EN)A carriage and mast assembly (10) has a mast (12) having a pair (16) of movable, inner uprights, a load lifting carriage (18) having a pair (22) of roller brackets, a pair (24) of lower roller assemblies having rollers (32) supported on sleeve bearings (30) and being connected to the pair (22) of roller brackets and pair (16) of inner uprights, and a pair (26) of upper roller assemblies having rollers (46) supported on anti-friction bearings (48) and being connected to the pair (22) of roller brackets and pair (16) of inner uprights. The carriage roller assemblies solve the problems of drag when lifting the carriage, which causes lifting of the inner uprights and thereby some loss of free-lift movement of the carriage, and load impact which causes premature failure of the lower roller assemblies. These problems are solved by using, on such an assembly for a fork lift track, lower carriage roller assemblies having sleeve bearings and upper carriage roller assemblies having anti-friction bearings.
(FR)Un assemblage a chariot et mat (10) possede un mat (12) ayant une paire (16) de montants mobiles, interieurs, un chariot de levage de charge (18) ayant une paire (22) de consoles a roues, une paire (24) d"assemblages a roues inferieures ayant des roues supportees sur des paliers a manchon (30) et reliees a la paire (22) de consoles a roues et a la paire (16) de montants interieurs, et une (26) d"assemblages a roues superieure des roues (46) supportees sur des paliers antifriction (48) et reliees a la paire (22) de consoles a roues et a la paire (16) de montants interieurs. Les assemblages a roues du chariot resolvent les problemes dus aux frottements lors du levage du chariot, ce qui levage des montants interieurs et par consequent une certaine perte du mouvement libre d"elevation du chariot, et l"impact de la charge qui provoque la defaillance prematuree des assemblages a roues inferieures. Ces problemes sont resolus en utilisant sur un tel assemblage pour un chariot elevateur a fourche, des assemblages a roues de chariot inferieures ayant des paliers a manchon et des assemblages a roues de chariot superieures ayant des paliers anti-friction.
