A CRAWLER PAD FOR THE TREAD BOARD OF A CRAWLER TRACK SHOE

摘要

A crawler pad to be mounted on the tread board of a crawler track shoe comprises an elastic pad body (1) and a core metal (2) buried in the elastic pad body (1). The core metal (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 rack teeth on their mutual surfaces which are inclined to permit the detachable hook (5) to slide in its inserting direction and intermesh one another in its withdrawing direction, thereby allowing the detachable hook (5) to be locked. The detachable hook (5) has preferably a groove for inserting a releasing pin on its surface where the rack teeth are formed. The releasing pin is operable to unlock intermeshing between the rack teeth of the locking member (4) and the detachable hook (5).
