A crawler pad to be mounted on the tread board of a crawler track shoe includes an elastic pad body (1) and a metal core (2) buried in the elastic pad body (1). The metal core (2) includes a locking member (4) movably inlaid therein, a fixed hook (6) rigidly secured to its one end, and a detachable hook (5) detachably secured to its other end. The locking member (4) and the detachable hook (5) have ratchet teeth (4a), (5a) on their mutual surfaces which are inclined to permit the detachable hook (5) to slide in its inserting direction and intermesh with one another in its withdrawing direction, thereby allowing the detachable hook (5) to be locked. The detachable hook (5) has preferably a groove (5b) for inserting a releasing pin (9) on its surface where the ratchet teeth are formed. The releasing pin (9) is operable to unlock intermeshing between the ratchet teeth of the locking member and the detachable hook (5). |
