Title (EN) SELF-LEVELING AND HEIGHT CONTROL HYDRAULIC SYSTEM
(FR) SYSTEME HYDRAULIQUE AUTOMATIQUE DE MISE A NIVEAU ET DE COMMANDE DE L'ELEVATION
Abstract: front page image
(EN)An implement having a rotary flow divider (16) controlling fluid to and from at least two independent hydraulic rams (26, 28) for raising and lowering the implement in a level manner. A counter (74, 274) totals the revolutions of the flow divider and actuates an electrical circuit which controls solenoid valves (44, 46, 220) to stop the implement at the proper height.
(FR)Outil possedant un diviseur (16) d'ecoulement rotatif commandant un fluide en direction et provenant d'au moins deux pistons hydrauliques independants (26, 28) permettant de lever et d'abaisser l'outil tout en gardant le niveau. Un compteur (74, 274) totalise les revolutions du diviseur d'ecoulement et actionne un circuit electrique qui commande des soupapes a solenoides (44, 46, 220) pour arreter l'outil a la hauteur voulue.
