Abstract
The crawler belt 20 is structured of a plurality of inner shoes 21; a plurality of outer shoes 30 arranged to oppose each of the inner shoes; an endless ring-shaped rubber belt member 26 retained between the inner shoes and outer shoes respectively opposing each other; and an endless ring-shaped steel wire 27 embedded in the belt member extending in the longitudinal direction. The inner shoes 21 are arranged side by side along the inner periphery of the belt member, the outer shoes are arranged side by side along the outer periphery of the belt member, and concave portions are arranged in the longitudinal direction between the inner shoes and formed openly toward the inner periphery for receiving the sprocket teeth. Thereby, it is possible to reduce the travel noise while maintaining the advantages of the strength, durability and repairability of steel crawler belts.
