s1, selecting a proper number of synchronous belts according to the width of the crawler belt (1) by taking the standard universal synchronous belts as a substrate; when the width of the crawler belt (1) needs to be increased, the process goes to step S21; when the width of the crawler belt (1) needs to be reduced, the step S22 is carried out;
s21, selecting a plurality of synchronous belts, and realizing connection combination of adjacent synchronous belts through a die-casting forming process;
and S22, selecting a synchronous belt, and cutting the synchronous belt until the width of the synchronous belt meets the width requirement of the crawler belt (1).
10. A track working process according to claim 9, characterized in that: the limiting lug (11) and the driven gear (12) are used for die-casting rubber on the inner surface of the synchronous belt in a corresponding shape through a rubber die-casting process.
