Title
(EN) GROUND CONTACTING BOOM HEIGHT CONTROL SYSTEM
(FR) SYSTEME DE CONTROLE DE HAUTEUR DE FLECHE PAR RAPPORT AU SOL
Abstract
(EN) A ground-contacting boom height control system for a vehicle comprising a frame supported for rolling movement along the ground; an operator cab for supporting an operator of the vehicle therein; a pair of boom structures extending laterally outward from opposing sides of the frame for pivotal movement up and down relative to the frame; a lift cylinder coupled between each boom structure and the frame for lifting the boom structures, each lift cylinder including a lifting circuit for lifting the boom when receiving hydraulic fluid under pressure from a conventional valve control and a lowering circuit for lowering the boom when receiving hydraulic fluid under pressure from a conventional valve control, and a conventional hydraulic circuit including a reservoir and a pump for supplying the hydraulic fluid under pressure from the reservoir to the lift cylinders.
(FR) L'invention concerne un système de contrôle de hauteur de flèche par rapport au sol, pour véhicule, comprenant un cadre en suspens destiné à être mis en mouvement le long du sol; une cabine d'opérateur ; une paire de structures de perche s'étendant latéralement vers des côtés opposés du cadre aux fins de pivotement vers le haut et le bas par rapport au cadre ; un cylindre d'élévation couplé entre chaque structure de flèche et le cadre pour l'élévation des structures de flèche, chaque cylindre comprenant un circuit d'élévation qui assure l'élévation de flèche sur réception de fluide hydraulique sous pression via un système de contrôle de vanne classique et un circuit d'abaissement assurant l'abaissement de flèche sur réception de fluide hydraulique sous pression via un système de contrôle de vanne classique, et un circuit hydraulique classique comprenant un réservoir et une pompe pour l'alimentation en fluide hydraulique sous pression depuis le réservoir vers les cylindres d'élévation.
