PROBLEM TO BE SOLVED: To increase the circumferential strength of a crawler to provide excellent durability by connecting a track link mounted on the inside of a shoe body to form a circumferentially continued rolling wheel track. SOLUTION: A track link 5 is connected to the core metal of a shoe body 4. In this connection, the bolt hole of the track link is fitted to a bolt hole in the center part 1b of the core metal, and the communicating bolt holes are bolted, whereby a pair of track links 5 is raised on both sides of the center part 1b. Each pin hole of the front and rear track links 5 is superposed, and a link pin is rotatably inserted to the superposed pin holes to connect both the track links 5, whereby a connected rolling wheel track is formed. The inside part of the connection part of the core metal is laid in the exposed state or covered with a thin rubber layer, and then combined with the track links 5. According to this structure, since the track links 5 are circumferentially connected, the circumferential mechanical strength of a crawler can be enhanced. |
