Patent ID: 7377601

Claim:
A detachable crawler comprising: a rubber belt part ( 4 ), said rubber belt part comprising a rubber elastic body ( 4 a ), a tensile reinforcing layer ( 2 ) and core bars ( 3 ), said tensile reinforcing layer ( 2 ) comprising a plurality of tensile reinforcing members arranged and embedded in the rubber elastic body ( 4 a ) in parallel rows, the rows extending in a crawler width direction, and the tensile reinforcing members extending in a crawler circumferential direction, and said core bars being embedded in the rubber elastic body at fixed intervals in the crawler circumference direction; and detachable pads, each of said detachable pads being one of a) a rubber pad ( 5 ) comprising a rubber elastic body and a metal core ( 6 ) having protrusions ( 7 ) having a height (H 1 ) on an inner peripheral side thereof and (b) a metal pad comprising a steel track shoe ( 21 ) having protrusions ( 7 ) having a height (H 1 ) on an inner peripheral side thereof, each of said detachable pads being mountable to and dismountable from a tread side of the rubber belt part ( 4 ) by fastening fixtures; wherein the rubber belt part ( 4 ) is provided with interfitted holes ( 12 ) having a height (H 2 ) on portions corresponding to the protrusions ( 7 ), the height (H 1 ) of each of the protrusions ( 7 ) is less than the depth (H 2 ) of each of the interfitted holes ( 12 ), the rubber elastic body ( 4 a ) is pressed by tightening fastening fixtures ( 8 , 18 ), and a tightening force of 4.90 to 78.5 MPa per unit area is applied to the rubber elastic body ( 4 a ) including the tensile reinforcing layer sandwiched between the core bars ( 3 ) and the detachable pads.
