Title (EN) MATERIALS HANDLING VEHICLE ESTIMATING A SPEED OF A MOVABLE ASSEMBLY FROM A LIFT MOTOR SPEED
(FR) VÉHICULE DE MANIPULATION DE MATÉRIAUX CONÇU POUR ESTIMER LA VITESSE D'UN ENSEMBLE MOBILE À PARTIR DE LA VITESSE DU MOTEUR D'UN APPAREIL DE LEVAGE
Abstract: front page image
(EN)A materials handling vehicle (100) is provided comprising: a support structure including a fixed member (200); a movable assembly coupled to the support structure (300); a hydraulic system (401); and a control system (1500). The support structure further comprises lift apparatus (400) to effect movement of the movable assembly relative to the support structure fixed member. The lift apparatus includes at least one ram/cylinder assembly. The hydraulic system includes a motor (301), a pump (302) coupled to the motor to supply a pressurized fluid to the at least one ram/cylinder assembly, and at least one electronically controlled valve (420) associated with the at least one ram/cylinder assembly. The control structure may estimate a speed of the movable assembly from a speed of the motor and control the operation of the at least one valve using the estimated movable assembly speed.
(FR)Un véhicule (100) de manipulation de matériaux comprend : une structure de support comprenant un élément fixe (200); un ensemble mobile couplé à la structure de support (300); un système hydraulique (401); et un système de commande (1500). La structure de support comprend en outre un appareil de levage (400) conçu pour déplacer l'ensemble mobile par rapport à l'élément fixe de la structure de support. L'appareil de levage comprend au moins un ensemble piston/cylindre. Le système hydraulique comprend un moteur (301), une pompe (302) couplée au moteur afin de fournir un fluide sous pression à/aux ensemble(s) piston/cylindre et au moins une soupape à commande électronique (420) associée à/aux ensemble(s) piston/cylindre. La structure de commande peut estimer une vitesse de l'ensemble mobile à partir d'une vitesse du moteur et elle peut commander le fonctionnement de la ou des soupapes à l'aide de la vitesse estimée de l'ensemble mobile.
