Abstract: 본 발명은 운반체부, 및 굴착 치부의 접촉 끝단으로 압입되는 고장력 팁을 구비하는 굴착 치부를 포함하는 개선된 굴착 부츠에 관한 것이다. 작동 시, 운반체부가 마련되고 불도저의 굴착 부츠 섕크, 또는 하나 이상의 굴착기 로더 버킷 섕크들에 운반체부가 끼워지도록 맞춰진다. 압입된 고장력 팁을 사용하게 되면, 작업 중 굴착 부츠를 정비할 필요성이 줄어들게 되는데, 이는 기계류를 자주 놀릴 필요가 없게 됨으로써, 많은 시간과 비용을 절감하게 되는 것을 의미한다. 팁이 닳기까지 전에 상당히 오랜 기간동안 사용될 수 있는 이유는 팁이 마멸과 찢어짐을 일으키는 경향이 적은 텅스텐과 같은 고장력 금속으로 마련되기 때문이다. 더군다나, 텅스텐 팁의 전방에 있는 단단하고 거친 암석은 보석들의 위치에 따른 굴착 경로에서 "부서진(explode)" 상태로 발견되는데 이 보석들은 그렇지 않다면 종래의 장비를 이용함으로 인해 유실되었을 것이다.
