Abstract
(EN)
A turning frame (11) comprises a center frame (12) and a tail frame (30). The center frame (12) comprises a front bottom plate (13), and left and right vertical plates (14, 17), which rise from the front side of the front bottom plate (13), configured by left and right bracket parts (14A, 17A) joined by pins to a lower boom (5A) and a boom cylinder (5E) of an operation device (5). The tail frame (30) comprises left and right I-beams (31, 32), and a rear bottom plate (33) connected between the I-beams (31, 32).The height dimension (A) of pin insertion holes (15A, 18A) for the boom provided on the bracket parts (14A, 17A) is set so as to be less than the height dimension (B) of the front end of top flange parts (31B, 32B) of the I-beams (31, 32).

L'invention concerne un bâti de retournement (11) qui comprend un bâti central (12) et un bâti de queue (30). Le bâti central (12) comprend une plaque inférieure avant (13), et des plaques verticales gauche et droite (14, 17), qui montent depuis le côté avant de la plaque inférieure avant (13), conçues par des parties d'étrier gauche et droite (14A, 17A) jointes par des goupilles à une flèche inférieure (5A) et un vérin de flèche (5E) d'un dispositif de fonctionnement (5). Le bâti de queue (30) comprend des poutres en I gauche et droite (31, 32), et une plaque inférieure arrière (33) reliée entre les poutres en I (31, 32). La dimension en hauteur (A) des trous d'insertion de goupille (15A, 18A) pour la flèche ménagés sur les parties d'étrier (14A, 17A) est définie de façon à être inférieure à la dimension en hauteur (B) de l'extrémité avant des parties de rebord supérieures (31B, 32B) des poutres en I (31, 32).
