Abstract
(EN)
A crane (1) is provided with: a crane body (4); a frame (16); a jib (18); a boom driving unit (16S); a jib driving unit (18S); an operation unit (85); a driving control unit (702); a suspension device (57); a determination unit (705); and an action restricting unit (703). The determination unit (705) determines if jib/boom angle conditions have been met. In accordance with the determination results from the determination unit (705), the action restricting unit (703) allows the posture of the crane (1) to change between a stowed position and a work position.
(FR)
La présente invention concerne une grue (1) qui est pourvue de : un corps de grue (4) ; un cadre (16) ; une flèche (18) ; une unité d’entraînement de bras (16S) ; une unité d’entraînement de flèche (18S) ; une unité de commande (85) ; une unité de commande d’entraînement (702) ; un dispositif de suspension (57) ; une unité de détermination (705) ; et une unité de restriction d’action (703). L’unité de détermination (705) détermine si des conditions d’angle de flèche/bras ont été satisfaites. En fonction des résultats de détermination provenant de l'unité de détermination (705), l'unité de restriction d'action (703) permet à la posture de la grue (1) de passer d'une position de stockage à une position de travail.
(JA)
クレーン(1)は、クレーン本体(4)と、ブーム(16)と、ジブ(18)と、ブーム駆動部(16S)と、ジブ駆動部(18S)と、操作部(85)と、駆動制御部(702)と、吊り装置(57)と、判定部(705)と、動作規制部(703)と、を備える。判定部(705)は、ジブブーム角度条件の成立を判定する。動作規制部(703)は、判定部(705)の判定結果に応じて、クレーン(1)が倒伏姿勢と作業姿勢との間で姿勢変更することを許容する。
