Abstract
(EN)
Provided is a work machine with which the rotational speed of a prime mover and the actuating speed of a hydraulic actuator can be appropriately set and selected. This work machine comprises a first setting member that receives a selection of a rotational speed setting for the prime mover, a second setting member that receives a selection of a speed setting for the hydraulic actuator, a rotational speed control unit that controls the actuation of the prime mover on the basis of the rotational speed setting, and a speed control unit that controls the actuation of the hydraulic actuator on the basis of the speed setting. In accordance with the rotational speed setting selected by the first setting member, the speed control unit changes the actuating speed of the hydraulic actuator corresponding to the speed setting selected by the second setting member.

L'invention concerne une machine de chantier avec laquelle la vitesse de rotation d'un moteur d'entraînement et la vitesse d'actionnement d'un actionneur hydraulique peuvent être réglées et sélectionnées de manière appropriée. Cette machine de chantier comprend un premier élément de réglage qui reçoit une sélection d'un réglage de vitesse de rotation pour le moteur d'entraînement, un second élément de réglage qui reçoit une sélection d'un réglage de vitesse pour l'actionneur hydraulique, une unité de commande de vitesse de rotation qui commande l'actionnement du moteur d'entraînement sur la base du réglage de vitesse de rotation, et une unité de commande de vitesse qui commande l'actionnement de l'actionneur hydraulique sur la base du réglage de la vitesse. En fonction du réglage de vitesse de rotation sélectionné par le premier élément de réglage, l'unité de commande de vitesse modifie la vitesse d'actionnement de l'actionneur hydraulique correspondant au réglage de vitesse sélectionné par le second élément de réglage.
