Abstract: A rubber crawler has a structure in which connecting members are sequentially fitted onto wing portions adjacent to each other without using steel cords for resisting tensile force applied to the rubber crawler. Accordingly, the rubber crawler of the present invention has excellent characteristics in that breakage of steel cords due to the tensile force can be prevented, and torsion of the rubber crawler can be reduced.

Abstract: In the present invention, cord protruding portions at each of ends of a crawler body are divided into groups such that each group has a protruding length different from those of other groups. The entire cord protruding portions at one end of the crawler body when seen from a direction perpendicular to a belt surface are disposed so as to present a male configuration, and the entire cord protruding portions at the other end of the crawler body are disposed so as to present a female configuration. The lines each connecting ends of cord protruding portions at the ends of the crawler body can be disposed so as to form a configuration that is one of terraced, tiered, and crenellated when seen from a direction perpendicular to a belt surface. When seen from the direction perpendicular to the belt surface, an overlapping portion of steel cords includes two outlines separated from each other in a longitudinal direction of the belt, and each outline includes a bent line. According to the present invention, a difference in rigidity between a portion of the crawler body including the overlapping portion of steel cords, and a portion not including the overlapping portion can be lessened as far as possible. Therefore, occurrence of vibration or noise can be effectively prevented. Further, a boundary between a high rigidity portion and a nonrigid portion of the rubber crawler is formed characteristically. As a result, occurrence of bending or buckling of the rubber crawler is alleviated, and the rubber crawler having excellent durability and reliability can be provided.

Abstract: When a conventional swivel working vehicle is constructed such that a real part of a swivel body is not extended beyond a traveling device in order to improve an operability at a small site, a balance weight must he significantly increased in weight so as to prevent falling and tumbling of a machine body. In the invention, left and right core metal projections of a crawler are laterally offset from a center line of the crawler and right and left lugs are formed on an outer peripheral surface of the crawler. The lugs are formed to assume the same shape on the right and left sides or laterally symmetrical shapes or occupy the same area on the right and left sides, and to be symmetrically shaped about a center of rotation of the swivel body between the left and right crawlers of the machine body.

Abstract: An assembly for joining ends of a drive track of an endless track drive system includes at least one connector member or connector member belt situated within the endless drive track, one or two retaining rods situated between abutting ends of the endless drive track, and a master link with a one-piece upper part and a one-piece lower part. The connector member(s) or connector member belt(s) is situated within the endless drive track in such a way that substantially parallel lengths of the connector member(s) or connector member belt(s) extend longitudinally of the endless drive track and loops of the connector member(s) or connector member belt(s) extend from ends of the endless drive track. The loops extending from abutting ends of the endless drive track are looped around an individual retaining rod, or two different retaining rods, and the retaining rod(s) and loops are sandwiched between the upper and lower master link parts by a fastening device which holds the upper and lower master link parts to one another. The retaining rod(s) is circumferentially grooved and connector member loops are disposed within the groove(s) so as to lie below the outer circumferential surface of the retaining rod(s), such that compression is exerted by the master link upon the retaining rod(s) and not upon the connector member loops. The simplified, high strength joint assembly can be utilized for interconnecting one or more drive track modules to form an endless drive track.
