A crawler pad with improved durability comprising: a pad body having ground contact parts formed protruding respectively on the both upper side surfaces thereof, a link coupling part dently formed on the center of the low surface thereof, and a plurality of installation holes formed between the ground contact parts; a steel core which is inserted and located inside the pad body, and has installation holes on its center to communicate with the installation holes of the pad body; a stop bump which is formed protrudingly on each of the front and back surfaces of the ground contact part, and functions to firstly prevent foreign materials from coming into space between neighboring pad bodies; overlap inclines and formed on the front and the back lower surfaces of the pad body respectively inclined downwards so as to be overlapped with those of neighboring another pad body and thereby to form an overlap region and secondly prevent foreign materials from coming into; a non-ground contact surface formed on the back surface of the ground contact part, in order to reduce the contact space with the ground; and reinforcing bumps, and longitudinally formed at the front, middle and back positions respectively on the upper surface of the steel core, upwardly protruding from said upper surface, wherein the steel core further comprises a central part having the installation holes with equal thickness, and edge reinforcing parts located respectively on both sides of the central part, and gradually greater in thickness toward both ends upwardly, a rubber path is formed on the center of the reinforcing bump with dented, which is located at the center among the reinforcing bumps, and, and thus flowed rubber is well flowed through the rubber path between the reinforcing bumps, and during vulcanization process of the pad body for good flow ability, a warp prevention sill is provided on the upper end surface of each of the reinforcing bumps, and protruding therefrom, and rubber-thickness enlargements are respectively formed on both sides of each of the reinforcing bumps, and, in which the center of the bump is formed as plane surface and the both sides are inclined downwards, and the portions of the pad body, which contact with the rubber-thickness enlargements, are better in the cushion ability than the portion thereof, which contacts with the center of each of the reinforcing bumps, and as the rubber thickness is enlarged. a pad body having ground contact parts formed protruding respectively on the both upper side surfaces thereof, a link coupling part dently formed on the center of the low surface thereof, and a plurality of installation holes formed between the ground contact parts; a steel core which is inserted and located inside the pad body, and has installation holes on its center to communicate with the installation holes of the pad body; a stop bump which is formed protrudingly on each of the front and back surfaces of the ground contact part, and functions to firstly prevent foreign materials from coming into space between neighboring pad bodies; overlap inclines and formed on the front and the back lower surfaces of the pad body respectively inclined downwards so as to be overlapped with those of neighboring another pad body and thereby to form an overlap region and secondly prevent foreign materials from coming into; a non-ground contact surface formed on the back surface of the ground contact part, in order to reduce the contact space with the ground; and reinforcing bumps, and longitudinally formed at the front, middle and back positions respectively on the upper surface of the steel core, upwardly protruding from said upper surface, wherein the steel core further comprises a central part having the installation holes with equal thickness, and edge reinforcing parts located respectively on both sides of the central part, and gradually greater in thickness toward both ends upwardly, a rubber path is formed on the center of the reinforcing bump with dented, which is located at the center among the reinforcing bumps, and, and thus flowed rubber is well flowed through the rubber path between the reinforcing bumps, and during vulcanization process of the pad body for good flow ability, a warp prevention sill is provided on the upper end surface of each of the reinforcing bumps, and protruding therefrom, and rubber-thickness enlargements are respectively formed on both sides of each of the reinforcing bumps, and, in which the center of the bump is formed as plane surface and the both sides are inclined downwards, and the portions of the pad body, which contact with the rubber-thickness enlargements, are better in the cushion ability than the portion thereof, which contacts with the center of each of the reinforcing bumps, and as the rubber thickness is enlarged.
