A crawler traveling device, wherein first and second support bodies (19) and (20) for supporting both end parts of the roller shaft (17a) of an upper roller (17) are formed of roller support parts (19b) and (20b) and a pair of connection piece parts (19a) and (20a) for connecting the roller support parts (19b) and (20b) to a carrier frame (10) in a generally channel shape and installed on the upper parts of track frames (11) and a cross frame (12) of the carrier frame (10) provided on the underside of a frame, whereby, when upper rollers are installed on the carrier frame provided on the underside of the frame, mud can be prevented from entering between the support bodies though a roller support mechanism is formed in a both roller shaft end support type so as to support both ends of the roller shafts by the support bodies.
L'invention concerne un dispositif roulant à chenilles dans lequel un premier (19) et un second (20) élément de support destinés à supporter les deux extrémités de l'arbre porte-galet (17a) d'un galet supérieur (17) sont constitués de pièces de support de galet (19b et 20b) et d'une paire de pièces de liaison (19a et 20a) servant à relier les pièces de support de galet (19b et 20b) à un cadre porteur (10) sous forme de canal, sur les parties supérieures de cadres de chenilles (11) et sur un cadre en croix (12) du cadre porteur (10) installé sur la face inférieure d'un cadre. Lorsque des galets supérieurs sont installés sur le cadre porteur installé sur la face inférieure du cadre, il est impossible que de la boue pénètre entre les éléments de support malgré la présence d'un mécanisme de support de galets du type à éléments de support supportant les deux extrémités des arbres porte-galet.
