とするクローラ−走行装置。A crawler belt 4 is installed on a running frame 1 that pivotally supports a plurality of wheels 2, and is suspended between an optical image driving wheel 3 and an idler wheel 3a, and the idler wheel 3a is moved in the front-rear direction. In the crawler traveling device, the idler wheel 3 is tensioned and loosened.
A pair of sliding rods 5 rotatably supported are attached so as to be slidable in the front-rear direction of the traveling frame 1, and the ends of the sliding rods 5, 5 are protruded inwardly so as to be thick. The head of an adjustment bolt 10 having a predetermined strength and serving as a safety pin is supported at the widthwise center of the running frame 1, while being removably screwed to both ends of a connecting base 9 formed in the flesh. and the other end threaded portion is a hole 9 provided in the protruding thick wall portion 9a of the connecting base 9.
a nut 10 passed through b and screwed onto the adjustment bolt 10
The crawler is characterized in that the idler wheel 3a can be moved in the tensioning direction via the sliding rod 5 by tightening b, and the adjustment bolt 10 is used as an overload relief mechanism in the event of an overload. Traveling device.
